Description

Conflict detection method and display device

Technical Field

The present application relates to the field of television technologies, and in particular, to a conflict detection method and a display device.

Background

A PVR (Personal video recorder) is an important function of a smart television or a set-top box, and a scheduled recording is an indispensable part of the PVR function. The user can select the recording time interval without the specific date in the 24-hour system from 0 o 'clock to 24 o' clock in advance, and correspondingly select different scheduled recording modes to add the corresponding specific date for the recording time interval so as to realize scheduled recording. The scheduled recording mode is divided into single recording and periodic recording. For periodic recordings, daily recordings every week, monday-friday recordings every week, saturday-friday recordings every week, or optionally days of recording every week, etc. are typically included.

In the related art, when the user selects the scheduled recording mode, the user can select from 7 options corresponding to monday through sunday, respectively. After the selection is finished, the television stores the reserved recording mode selected by the user in a bit mode through a reserved recording mode value consisting of 7 bits (numerical values of 0-255) which respectively correspond to Monday to Sunday. However, because the above operations are relatively complicated, most of the current tv manufacturers provide some commonly used reserved recording modes to users in the standard reserved recording mode, so that the users can select the standard reserved recording mode only once, for example, recording on monday to friday of each week or recording on saturday to sunday of each week. On the basis, the television manufacturers additionally set special reserved recording mode values (values larger than 255) for the standard reserved recording modes so as to store the reserved recording modes after the corresponding standard reserved recording modes are selected by the users.

However, since the above-mentioned scheme adopts different representation methods for the standard scheduled recording mode and the non-standard scheduled recording mode, when performing the scheduled recording conflict detection, it is necessary to detect whether the recording time interval of each day in the week in the scheduled recording mode conflicts with the recording time interval of the newly added scheduled recording task one by one according to the scheduled recording mode of each existing scheduled recording task, so that the conflict detection process is very complicated.

Disclosure of Invention

The application provides a conflict detection method and display equipment, which are used for determining whether a reservation conflict exists only through one-time reservation conflict detection when the reservation conflict is detected.

In a first aspect, a collision detection method is provided, including:

responding to the newly-added reservation instruction, and acquiring a newly-added reservation recording task; the newly-added reserved recording task comprises a first reserved recording mode value, the first reserved recording mode value is composed of 7 bits, different bits represent different time attributes, and the time attributes comprise Monday to Sunday;

aiming at each existing reserved recording task, when the first reserved recording mode value and the second reserved recording mode value are both used for indicating single recording, checking whether an intersection exists between the recording time interval of the newly added reserved recording task and the recording time interval of the existing reserved recording task; the second reserved recording mode value is a reserved recording mode value of the existing reserved recording task;

and if so, determining that the newly-added reserved recording task and the existing reserved recording task have a reservation conflict.

In a second aspect, there is provided a display device comprising:

the display is used for displaying a playing picture;

the user interface is used for receiving instructions input by a user;

a controller for performing:

responding to the newly-added appointed recording task instruction to obtain a newly-added appointed recording task; the newly-added reserved recording task comprises a recording time interval and a first reserved recording mode value; the first reserved recording mode value is used for indicating a reserved recording mode and is composed of 7 bits, and the 7 bits respectively represent Monday to Sunday;

for each existing reserved recording task, when the first reserved recording mode value and the second reserved recording mode value of the existing reserved recording task are both used for indicating single recording, checking whether an intersection exists between the recording time interval of the newly added reserved recording task and the recording time interval of the existing reserved recording task; and when the intersection exists, determining that the newly-added reserved recording task and the existing reserved recording task have a reservation conflict.

In the above-described embodiment, since all the scheduled recording modes are represented by the scheduled recording mode value composed of the 7-bit bits respectively corresponding to monday to sunday, an effect of representing all the scheduled recording modes by using the same representation method is achieved. On the basis, whether the reserved recording task is reserved once or not is judged through the reserved recording mode value, whether intersection exists between the recording time interval of the newly increased reserved recording task and the recording time interval of the existing reserved recording task or not is directly detected when the newly increased reserved recording task and the reserved recording mode of the existing reserved recording task are both recorded once, and the newly increased reserved recording task and the existing reserved recording task are determined to have a reserved conflict when the intersection is detected, so that the embodiment of the application can simply and conveniently determine whether the reserved conflict exists through one-time reserved conflict detection.

In some embodiments, since the display device does not use a uniform reserved mode representation to represent all reserved recording modes, when detecting a reserved conflict, it is necessary to detect, one by one, whether a recording time period of each day in a week in the reserved recording mode conflicts with a recording time period of a newly added reserved recording task according to the reserved recording mode of each existing reserved recording task, so that a conflict detection process is very complicated.

In view of the above, the present embodiment provides a conflict detection method, so that when a reservation conflict is detected, it can be determined whether there is a reservation conflict only by one reservation conflict detection.

Next, with reference to the contents shown in fig. 2A to fig. 2D, 4 different detection methods in the collision detection method provided in the embodiment of the present application are respectively described.

With reference to the method shown in fig. 2A, the collision detection method provided in the embodiment of the present application may include the following steps:

s21, responding to the newly added reservation recording task instruction to obtain a newly added reservation recording task; the newly-added appointed recording task comprises a recording time interval and a first appointed recording mode value; the first reserved recording mode value is used for indicating a reserved recording mode and is composed of 7 bits, and the 7 bits respectively represent Monday to Sunday;

as an example, the new scheduled recording task obtained in response to the new scheduled recording task instruction may be a scheduled recording task newly set by the user, or a new scheduled recording task obtained by modifying an existing scheduled recording task by the user.

As one example, the scheduled recording mode may include both single recording and periodic recording. For a periodic recording of such a reservation, it may include: on monday to friday every week, on saturday to sunday every week, on monday to sunday every week, or optionally on several days every week.

As an example, the reserved recording mode value is used to indicate a reserved recording mode, and is composed of 7 bits, which represent monday through sunday, respectively. As one implementation, the most significant bit to the least significant bit of the 7-bit may correspond to sunday to saturday, respectively. In the following description, unless otherwise specified, the highest bit to the lowest bit of the 7-bit may correspond to sunday to saturday, respectively, for example.

As an example, for a 7-bit in the reserved recording mode value, the representation of different reserved recording modes can be realized by different values of different bits. When the bit value is 1, the recording is performed on the day represented by the bit in each week. When bit takes 0, the opposite is true. Here, if each bit in the reserved recording mode value is 0, it indicates that the reserved recording mode is single recording. Here, as a simple example, if the reserved recording mode value is 1111111B, it indicates that the reserved recording mode is recording on monday to sunday of each week. If the value of the reserved recording mode is 1000001B, the reserved recording mode is recorded on saturday and sunday of each week.

S22, aiming at each existing reserved recording task, when the first reserved recording mode value and the second reserved recording mode value of the existing reserved recording task are both used for indicating single recording, checking whether the recording time interval of the newly added reserved recording task and the recording time interval of the existing reserved recording task have intersection or not; if yes, go to S23; if not, go to S24.

As an example, the execution process of the scheduled recording task in which the scheduled recording mode is single recording will be described here. When a user sets a reserved recording task, if the reserved recording mode is selected as single recording, the display equipment can determine the corresponding reserved date according to the current time of the 24-hour system of the current date and the recording starting time of the 24-hour system. Specifically, if the recording start time of the 24-hour system is earlier than the current time of the 24-hour system of the current date, the scheduled date is the current date. Otherwise, the appointment date is the next day of the current date. For example, if the user selects 8 o ' clock to 9 o ' clock as the recording time interval in the time period of 24 hours system at 8 o ' clock of 1 o ' clock of 2020 year, and selects the scheduled recording mode as single recording, the scheduled date of the scheduled recording task is 1 o ' clock 2 of 2020 year since the current time of 24 hours system at 8 o ' clock of the current date is already later than the recording start time of the recording time interval of 24 hours system set by the user at 8 o ' clock.

As an example, since the single-reserved recording mode only corresponds to one recording time interval, whether the recording time interval of the newly added reserved recording task and the recording time interval of the existing reserved recording task intersect with each other or not can be directly compared to determine whether a reservation conflict exists or not.

As an example, the recording start Time and the recording end Time of the recording period may be both expressed by UTC (Universal Time Coordinated) in seconds. For example, since the UTC in units of seconds is the number of seconds relative to 0 minutes 0 seconds at 0 point 01/1970, if the recording start time is 0 minutes 10 seconds at 0 points 0 minutes 0 at 01/1970, the UTC in units of seconds is 10.

It should be noted that, when the UTC in seconds is used to represent the recording start time and the recording end time, the time may be adjusted according to the time zone where the display device is located.

As an example, when performing reservation conflict detection, it may be implemented by a recording start time and a recording end time of a recording period. Specifically, when the recording start time and the recording end time of the recording time period can be both expressed by UTC in units of seconds, if the recording start time of the newly-added scheduled recording task is less than or equal to the recording start time of the existing scheduled recording task, and the recording end time of the newly-added scheduled recording task is greater than the recording end time of the existing scheduled recording task, or the recording start time of the newly-added scheduled recording task is greater than the recording start time of the existing scheduled recording task, and the recording start time of the newly-added scheduled recording task is less than the recording end time of the existing scheduled recording task, it can be determined that the scheduled recording task conflicts with the existing scheduled recording task.

And S23, determining that the newly-added reserved recording task and the existing reserved recording task have reservation conflict.

As an example, when it is determined that the recording time period of the newly added scheduled recording task intersects with the recording time period of the existing scheduled recording task, it may be determined that a scheduled conflict exists between the newly added scheduled recording task and the existing scheduled recording task.

As an example, after determining that the newly added scheduled recording task has a reservation conflict with the existing scheduled recording task, the display device may display it on the display to remind the user to modify it. For example, the newly added scheduled recording task a and the existing scheduled recording task B shown in fig. 2a1 are two conflicting scheduled recording tasks.

And S24, determining that the newly-added reserved recording task and the existing reserved recording task do not have a reservation conflict.

As an example, when it is determined that there is no intersection between the recording time period of the newly added scheduled recording task and the recording time period of the existing scheduled recording task, it may be determined that there is no scheduling conflict between the newly added scheduled recording task and the existing scheduled recording task.

This completes the description of fig. 2A.

With reference to the content shown in fig. 2B, the conflict detection method provided in the embodiment of the present application includes the following steps:

s21, responding to the newly-added reservation recording task instruction to obtain a newly-added reservation recording task; the newly-added reserved recording task comprises a recording time interval and a first reserved recording mode value; the first reserved recording mode value is used for indicating a reserved recording mode and is composed of 7 bits, and the 7 bits respectively represent Monday to Sunday.

As an example, the related content of S21 has been described in the foregoing, and is not described herein again.

S25, when the first reserved recording mode value is used for indicating single recording and the second reserved recording mode value is used for indicating periodic recording, checking whether the recording start time of the newly-added reserved recording task is later than the current nearest recording start time of the existing reserved recording task, and the bit which indicates the week M in the second reserved recording mode value is an appointed value; the week M is determined by the first appointment date of the newly-added appointment recording task; if yes, go to S26; if not, go to S27.

As an example, a description will be given here of an execution process of a scheduled recording task in which the scheduled recording mode is a periodic recording. The recording is performed periodically, i.e., at least one day of the week, and thus, the recording period of the scheduled recording task is continuously updated over time. Here, the scheduled recording mode is used as the monday and wednesday recording of each week, the recording time interval of the 24-hour system is 9 to 10 o 'clock, and if the current date is 2/2020 (sunday), the scheduled recording task is based on the current latest recording time interval being 9 to 10 o' clock of 2/3/2020 (monday). After a period of time has elapsed, for example, the current time becomes 9 o ' clock of 2/2020, that is, the recording start time of the recording time interval is reached, the scheduled recording task is started to be executed, and the current latest recording time interval is updated to 9 o ' clock to 10 o ' clock of 2/5/2020 (wednesday).

As an example, since the existing scheduled recording task is a periodic recording and the new scheduled recording task is a single recording, there may be a case where the scheduled date of the existing scheduled recording task from the current latest time is not the scheduled date of the new scheduled recording task, but the scheduled date of the new scheduled recording task is the same as the scheduled date after the existing scheduled recording task. Because the reservation date of the single reservation can only be the current date or the next day of the current date, if the situation can occur, the recording starting time of the newly-added reservation recording task is certainly later than the recording starting time of the existing reservation recording task which is nearest to the current, and therefore, whether the newly-added reservation recording task and the existing reservation recording task are executed on the same day can be determined through the judgment of the step.

For example, assuming that the current date is 1 month and 1 day of 2020 (wednesday), the current 24-hour time point is 8 points. If the user sets the newly-added scheduled recording task as single recording and the recording time interval of the 24-hour system is 7 o 'clock to 9 o' clock, the display device may generate the recording time interval of the date according to the above contents as 7 o 'clock to 9 o' clock of the 1 month 2 (thursday) day of 2020 year. The mode of the reserved recording task is recorded on wednesday and thursday of each week, and the recording time interval of 24 hours is 8-half to 9. Then, the recording period related to the date that the display device can generate according to the above is 8 half-hour to 9-hour of 1 month and 1 day of 2020. Since there is no intersection between 7 o 'clock to 9 o' clock of the 2020 year 1/month 2 day and 8 o 'clock to 9 o' clock of the 2020 year 1/month 1 day, however, the recording time period corresponding to the recording on thursday is 8 o 'clock to 9 o' clock of the 2020 year 1/month 2 day, which is overlapped with 7 o 'clock to 9 o' clock of the 2020 year 1/month 2 day.

As an example, the first scheduled date may be determined according to a recording period of the newly added scheduled recording task. For example, if the recording time interval of the newly added scheduled recording task is 3 o 'clock to 5 o' clock in 2 month and 5 month in 2020, the first scheduled date is 2 month and 5 day in 2020.

As one example, monday M may be any day of monday through sunday. The specific day of the week M is the day of the week, and it is determined according to the specific date of the first appointment date. For example, if the first appointment date is 2020, 2/5, then wednesday M is wednesday corresponding to 2020, 2/5.

And S26, determining the recording time interval of the existing reserved recording task on the first reserved date, and determining that the reserved conflict exists between the newly-added reserved recording task and the existing reserved recording task when the intersection exists between the recording time interval and the recording time interval of the newly-added reserved recording task.

As an example, if the first scheduled date of the newly added scheduled recording task is determined, the time length of one or more days may be added to the current recording time interval of the existing scheduled recording task to obtain the recording time interval of the existing scheduled recording task on the scheduled date. Taking the recording start time and the recording end time of the recording time interval as an example, which are both represented by UTC in units of seconds, if the scheduled date is 1, 2 and 2020, and the current latest recording time interval of the existing scheduled recording task is 1577836800-1577840400 (8 o 'clock to 9 o' clock on 1, 1 and 2 and 2020), the number of seconds of one day (86400) is added on the basis, and the recording time interval of the existing scheduled recording task on the scheduled date is 1577923200-1577926800.

As one example, when performing reservation conflict detection, it may be determined whether a reservation conflict exists by detecting whether there is an intersection of recording periods. On the basis, if the recording starting time of the newly-increased reserved recording task is less than or equal to the recording starting time of the existing reserved recording task on the reserved date of the newly-increased reserved recording task, the recording ending time of the newly-increased reserved recording task is greater than the recording ending time of the existing reserved recording task on the reserved date of the newly-increased reserved recording task, or the recording starting time of the newly-increased reserved recording task is greater than the recording starting time of the existing reserved recording task on the reserved date of the newly-increased reserved recording task, and the recording starting time of the newly-increased reserved recording task is less than the recording ending time of the existing reserved recording task on the reserved date of the newly-increased reserved recording task, the newly-increased reserved recording task and the existing reserved recording task can be determined to have conflict.

And S27, when the recording time interval of the existing reserved recording task closest to the current time interval and the recording time interval of the newly added reserved recording task have intersection, determining that a reserved conflict exists.

As an example, if the determination result of S25 is no, it indicates that the existing scheduled recording task does not have the same date as the scheduled recording task after the existing scheduled recording task, but the date of the existing scheduled recording task is not the same as the date of the newly added scheduled recording task. Then, the recording time interval of the existing reserved recording task closest to the current time interval and the recording time interval of the newly added reserved recording task can be directly detected to determine whether an intersection exists. The detection manner of whether there is intersection in the recording time periods in this step is similar to S23, so reference may be made to the corresponding description in S23, and details are not repeated here.

This completes the description of fig. 2B.

With reference to the content shown in fig. 2C, the conflict detection method provided in the embodiment of the present application includes the following steps:

s21, responding to the newly-added reservation recording task instruction to obtain a newly-added reservation recording task; the newly-added appointed recording task comprises a recording time interval and a first appointed recording mode value; the first reserved recording mode value is used for indicating a reserved recording mode and is composed of 7 bits, and the 7 bits respectively represent Monday to Sunday.

S28, when the first reserved recording mode value is used for indicating periodic recording and the second reserved recording mode value is used for indicating single recording, checking whether the recording start time of the existing reserved recording task is later than the current nearest recording start time of the newly-added reserved recording task, wherein the bit indicating the week N in the first reserved recording mode value is an appointed value; the week N is determined by a second appointment date of the existing appointment recording task; if yes, go to S29; if not, go to S30.

As an example, since the newly added scheduled recording task is a periodic recording and the existing scheduled recording task is a single recording, there may be a case where the date of the newly added scheduled recording task from the current latest scheduled recording task is not the date of the existing scheduled recording task, but the date of the existing scheduled recording task is the same as the date of the newly added scheduled recording task after the current scheduled recording task. Because the reservation date of the single reservation can only be the current day or the current next day, if the situation can occur, the recording starting time of the existing reserved recording task is certainly later than the recording starting time of the newly-added reserved recording task which is closest to the current day, and therefore, whether the newly-added reserved recording task and the existing reserved recording task are executed on the same day can be determined through the judgment of the step.

As an example, the second scheduled date may be determined according to a recording period of an existing scheduled recording task. For example, if the recording time interval of the scheduled recording task is 3 o 'clock to 5 o' clock in 2 month and 5 month in 2020, the second scheduled date is 2 month and 5 days in 2020.

As an example, Wedns may be any of Monday through Sunday. The specific day of the week N is the day of the week, and it is determined according to the specific date of the second appointment date. For example, if the second appointment date is 2/5/2020, then monday is wednesday corresponding to 2/5/2020.

And S29, determining the recording time interval of the newly-added appointed recording task on the second appointed date, and determining that the newly-added appointed recording task and the existing appointed recording task have an appointed conflict when the recording time interval and the recording time interval of the existing appointed recording task have an intersection.

As an example, the present step is similar to the aforementioned S26, so the corresponding description in the aforementioned S26 can be referred to, and the description is not repeated here for the moment.

And S30, when the recording time interval of the newly added reserved recording task closest to the current time interval and the recording time interval of the existing reserved recording task have intersection, determining that a reserved conflict exists.

As an example, this step is similar to the aforementioned S27, so the corresponding description in the aforementioned S27 can be referred to, and the description is not repeated here.

This completes the description of fig. 2C.

With reference to the content shown in fig. 2D, the conflict detection method provided in the embodiment of the present application includes the following steps:

s21, responding to the newly-added reservation recording task instruction to obtain a newly-added reservation recording task; the newly-added reserved recording task comprises a recording time interval and a first reserved recording mode value; the first reserved recording mode value is used for indicating a reserved recording mode and is composed of 7 bits, and the 7 bits respectively represent Monday to Sunday;

S31, when the first scheduled recording mode value and the second scheduled recording mode value are both used for indicating periodic recording, determining all bits which are the same as the designated value in the first scheduled recording mode value and the second scheduled recording mode value, and selecting a target bit from the determined bits; the week X represented by the target bit is nearest to the week Z corresponding to the current date and is later than the week Z;

as an example, if the newly added scheduled recording task and the existing scheduled recording task are both in the periodic scheduled recording mode, a situation may occur in which the scheduled date of the newly added scheduled recording task from the current time is different from the scheduled date of the existing scheduled recording task from the current time, but the scheduled date of the newly added scheduled recording task is completely or partially the same as the scheduled date of the existing scheduled recording task except the last time. For example, the current date is wednesday, the scheduled recording mode of the newly added scheduled recording task is thursday and friday recording every week, and the scheduled recording mode of the existing scheduled recording task is friday and saturday recording every week. Then, it is necessary to compare whether a conflict exists between the newly added scheduled recording task and the existing scheduled recording task in the recording time period of friday.

As an example, in this step, all bits that are the same designated value may be obtained according to the values of the bits in the first and second reserved recording mode values. The specified value here may be 1. For example, if the first reserved recording mode value is 1000001B and the second reserved recording mode value is 1010001B, the bits that are the designated values are the 6 th bit and the 0 th bit.

As an example, both Sunday Z and Sunday X may be any of Monday through Sunday. The specific condition is the day of the week, and can be determined according to actual conditions.

As one example, the target bit may be determined based on the current date. For example, if bits having a specified value are the 6 th bit and the 0 th bit, and the 7 th bit corresponds to sunday to saturday from the highest bit to the lowest bit, it can be seen that the bits indicate sunday and saturday, respectively. If the current date is 29 days (wednesday) in 1 month in 2020, the condition that the week X represented by the target bit is nearest to the week Z corresponding to the current date and is later than the week Z can be determined, and the target bit is the bit of the 0 th bit.

S32, determining a target date according to the week X, and determining that the newly-added scheduled recording task and the existing scheduled recording task have a scheduling conflict when the recording time interval of the newly-added scheduled recording task on the target date and the recording time interval of the existing scheduled recording task on the target date have an intersection.

As one example, the target date may be a date corresponding to the nearest week X in the future from the current date. For example, assuming that the current date is 2020, 1, 6 days (monday), and saturday X is saturday, the target date is 2020, 1, 11 days (saturday).

As an example, the implementation manner of determining the recording time period of the newly-added scheduled recording task on the target date and the recording time period of the existing scheduled recording task on the target date is similar to the implementation manner of S29, so that reference may be made to the corresponding description in S29, which is not repeated here.

As an example, the implementation manner of determining whether there is a reservation conflict is similar to the implementation manner of S30, so that reference may be made to the corresponding description in S30, which is not repeated here.

This completes the description of fig. 2D.

It should be noted that the steps shown in fig. 2A to 2D may be combined and used in the same embodiment, or the steps shown in any two, three or four of fig. 2A to 2D may be combined and used in the same embodiment.

How the display device displays the scheduled recording task will be described with reference to fig. 2E.

As shown in fig. 2E, the process may include the following steps:

s33, receiving a display instruction;

as an example, the display device may receive a display instruction sent by the control device, where the display instruction may be used to instruct to display some specific scheduled recording tasks or may be used to instruct to display all scheduled recording tasks recorded in the display device. The display instruction is used for indicating which reserved recording tasks are displayed, and can be determined according to actual conditions.

S34: responding to the display instruction, and judging whether a reserved recording mode value of a reserved recording task to be displayed is a standard reserved recording mode value; if yes, go to step S35; if not, go to step S36;

as an example, the scheduled recording tasks to be displayed are different according to the content indicated by the display instruction. For example, when the display instruction is used to instruct the display of all scheduled recording tasks recorded in the display device, the scheduled recording tasks to be displayed may be all existing scheduled recording tasks in the display device. Otherwise, the scheduled recording task to be displayed may also be some specific existing scheduled recording task.

As an example, the standard scheduled recording mode may include at least one of the following 4:

1. single recording, wherein the corresponding standard reserved recording mode value is 0000000B;

2. recording from Monday to Sunday of each week, wherein the corresponding standard reserved recording mode value is 1111111B;

3. recording on Mondays to Friday every week, wherein the corresponding standard reserved recording mode value is 0111110B;

4. every saturday to sunday of the week is recorded, and the corresponding standard reserved recording mode value is 1000001B.

As an example, after the scheduled recording mode is determined as the standard scheduled recording mode, the corresponding value of the scheduled recording mode is used as the value of the standard scheduled recording mode.

S35, displaying the standard reserved recording mode indicated by the standard reserved recording mode value;

as an example, when the scheduled recording mode value of the scheduled recording task to be displayed is the standard scheduled recording mode value, the standard scheduled recording mode indicated by the standard scheduled recording mode value may be displayed. For example, if the value of the reserved recording mode of the reserved recording task to be displayed is 0000000B, the reserved recording mode indicated by 0000000B, that is, single recording, may be displayed.

It should be noted that what language and what text content are used to display the standard scheduled recording mode in S52 can be flexibly set according to actual situations. For example, in an English country, the language may be set to English; in a Chinese country, the language may be set to Chinese. The following describes an example of display contents of the standard reserved recording mode by taking english as an example:

1. the single recording can be displayed as Once on a display; such as the existing scheduled recording task E in fig. 2E 1.

2. Monday through Sunday of each week are recorded and can be displayed as Daily on the display; such as the existing scheduled recording task D in fig. 2E 1.

3. Monday to Friday records every week and may be displayed on the display as Monday to Friday.

4. Saturday to Sunday are recorded every Saturday to Sunday and may be displayed on the display.

And S36, determining the bit with the value as the designated value in the reserved recording mode value, and taking the week I represented by the bit with the value as the designated value as the reserved recording mode and displaying.

As an example, the week I can be any one or more of Monday to Sunday, and particularly the day of the week, which can be determined according to the actual situation. For example, assuming that the reserved recording mode value is 1001101B, bit taking the designated value indicates sunday, wednesday, thursday, and saturday. For another example, if the reserved recording mode value is 0100000B, bit whose value is the specified value indicates monday. Such as the existing scheduled recording task C in fig. 2E 1.

This completes the description of fig. 2E.

In the embodiment, the reserved recording mode value is formed by adopting the 7 bits which respectively correspond to different time attributes in one week, and the standard reserved recording mode and the non-standard reserved recording mode are uniformly represented by the reserved recording mode value, so that when the reserved recording mode of the reserved recording task is displayed in the embodiment, the numerical value conversion is not needed, the display process is simplified, and errors are not easy to occur.

While the preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including the preferred embodiment and all changes and modifications that fall within the scope of the present application.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include such modifications and variations.
