Selector for switching the output data signal from the
It is an MPEG decoder as a decoder unit that decodes and outputs a PEG-compressed stream.
The hard disk device 2, the MPEG decoder 8 and the control unit 1 are connected to each other by a control bus 11. The stream processing unit 4 and the TS / PS converter 6 correspond to the first signal processing unit, and the emergency broadcast information processing unit 5 corresponds to the second signal processing unit.

FIG. 3 is a structural diagram of a digital signal output from the tuner section 3, and FIG. 4 is a structural diagram of a TMCC signal.

Generally, in the case of BS digital broadcasting, a super frame composed of 8 frames is transmitted as one unit. Each frame is composed of a synchronization signal, a TMCC signal, and a main signal. The main signal is based on the MPEG system, and 48 MPs are included in one frame.
EG-TS (Transport Stream) is included, and a maximum of 8 TSs can be transmitted in plural.

Next, this conventional video information recording / reproducing apparatus 2
The recording operation of 0 will be described. Tuner section 3 in general
The digital signal output from is composed of the synchronizing signal, the TMCC, and the main signal as described above. The stream processing unit 4 selects the TS signal requested by the viewer from the plurality of TS signals and outputs it. The TS / PS converter 6 converts this TS signal into a PS signal and then outputs it to the hard disk device 2.

When the hard disk device 2 is in the recording state, the PS signal output from the TS / PS converter 6 is recorded in the hard disk device 2. The PS signal output from the TS / PS converter 6 is also output to the selector 7 at the same time, and at this time, the selector 7 selects and outputs the PS signal. Further, the PS signal input to the MPEG decoder 8 is converted into a luminance signal and a color difference signal here and output to a display such as a TV.

Next, the reproducing operation of the video information recording / reproducing apparatus 20 will be described. In this case, the signal reproduced from the hard disk device 2 is output to the selector 7.
At this time, the selector 7 selects this reproduction data signal from the hard disk device 2 and outputs it to the MPEG decoder 8. Further, the reproduction data signal input to the MPEG decoder 8 is converted into a luminance signal and a color difference signal as in the case of the above-described recording and is output to a display such as a TV.

In general, current hard disk devices have very high information read and write speeds and a transfer capacity of several tens of Mbits / second or more. The access speed is also very high, with an average of several msec. On the other hand, the transfer rate of video information is about several Mbit / sec. Therefore, for example, during recording of video information, the waiting time becomes longer than the writing operation time. By performing a time-division process in which a reproducing operation and a recording operation are further performed during this waiting time, a plurality of simultaneous recording / reproducing operations can be performed.

Next, the time-free reproduction utilizing this characteristic will be described. Time-free playback is a recording operation that starts the program recording at the same time as the TV screen is paused when the viewing is interrupted by a sudden visitor or telephone while watching the TV, and continues when the program returns again. This is a function that allows the user to watch the continuation of the program without interruption during playback by continuing the playback from the recording start point. This will be described in more detail below.

When a digital broadcast is viewed using the tuner section 3 of the information recording / reproducing apparatus 20, the output data signal from the TS / PS converter 6 is selected by the selector 7 and output to the MPEG decoder 8, and further. This signal is MP
The EG decoder 8 converts the luminance signal and the color difference signal into a TV.
It is output to the display such as.

When the viewer operates a predetermined operation button (not shown) to indicate the interruption of TV viewing, the control section 1 senses this operation and the MPEG decoder 8 repeats the video signal currently being displayed. Control to output.
As a result, the screen is temporarily stopped. At this time, the control unit 1 also controls the hard disk device 2 to start recording the output signal from the TS / PS converter 6 at the same time.

Further, after the screen is temporarily stopped, the output signal from the hard disk device 2 is selected as the output signal of the selector 7. However, in this state, since the hard disk device 2 has not started reproduction, the still image of the decoder 8 continues to be output to the TV.

When the viewer performs an operation for canceling the interruption of the viewing, the hard disk device 2 continues the current recording based on a command from the control unit 1 while continuing from the beginning of the currently recorded program. Start playback. Since the reproduction signal of the hard disk device 2 remains selected in the selector 7, the reproduction signal from the hard disk device 2 is input in the decoder 8 and converted into a luminance signal and a color difference signal. At this time, the paused state of the decoder 8 is released at the same time. With the above operation, the time-free operation is realized, and the user can continuously view the video delayed by the interrupted time.

[0016]

When the emergency broadcast is started during such time-free reproduction, the emergency broadcast information processing unit 5 detects the emergency broadcast and selects the TS signal designated as the emergency broadcast. A command is issued to the stream processing unit 4. In the stream processing unit 4, the TS signal of the emergency broadcast is selected according to the instruction from the emergency broadcast information processing unit 5. At this time, since the output of the hard disk device 2 is selected by the selector 7, it is delayed for the viewer to notice this emergency broadcast by the interrupted time.

Due to its nature, emergency broadcasts are broadcast in the event of an urgent natural disaster such as an earthquake or tsunami, so it is necessary to inform the viewers so that there is no delay in the emergency broadcast transmission due to time-free reproduction. is there. As described above, the conventional method has a problem that the emergency broadcast cannot be viewed in real time during the time-free reproduction.

The object of the present invention is to solve these problems,
Even during the time-free reproduction, the emergency broadcast can be viewed in real time when the emergency broadcast is started, and the program can be quickly viewed from the scene where the program was interrupted when the emergency broadcast is finished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 is a first embodiment of an information recording / reproducing apparatus according to the present invention.
3 is a block diagram showing the configuration of the main part of FIG.

The information recording / reproducing apparatus 10 shown in the figure differs from the conventional video information recording / reproducing apparatus 20 shown in FIG. 5 mainly in that the control signal from the emergency broadcast information processing unit 5 causes A selector 9 corresponding to a second selector for selecting the output signal from the selector 7 which is the first selector and the output data signal from the TS / PS converter 6, the stream processing unit 4, and the emergency broadcast. The information processing unit 5 is newly connected to the control bus 11. The selector 7 and the selector 9 correspond to signal selecting means.

Therefore, in the information recording / reproducing apparatus 10 of the first embodiment shown in FIG. 1, the same or corresponding portions as those of the conventional video information recording / reproducing apparatus 20 shown in FIG. The description of the common parts of the above is omitted, and the different points will be mainly described below.

First, the information recording / reproducing apparatus 10 shown in FIG.
However, the description will be made assuming the case of the above-mentioned time-free reproduction state. For details on time-free playback,
Since it is as described above, the description is omitted here. At this time, when normal broadcasting is being performed, the reproduction data signal from the hard disk device 2 is selected by the selector 7 which is the first selector, and the output signal from the selector 7 is further selected by the selector 9 which is the second selector. To be selected,
A reproduction data signal from the hard disk device 2 is input to the decoder 8.

In this way, when the emergency broadcast is started while the information recording / reproducing apparatus 10 is in the time-free state, TM
The activation control signal in the CC signal and the emergency broadcast descriptor in the PMT are set. When the control unit 1 reads this information from the emergency broadcast information processing unit 5 and confirms that the activation control signal and the emergency broadcast descriptor are set, the TS of the emergency broadcast corresponding to the emergency broadcast program data specified by service_id is transmitted. The stream processing unit 4 is instructed to output the signal. The stream processing unit 4 outputs the TS of the emergency broadcast from the stream processing unit 4 according to the instruction from the control unit 1.

When the emergency broadcast is started, the selector 9
Then, the output data signal from the TS / PS converter 6 is selected. With the above operation, the emergency broadcast can be viewed in real time even during the time-free reproduction.

The above description describes the operation when the apparatus is in the time-free reproduction state. However, not only when the apparatus is in the time-free state, but also when the hard disk apparatus 2 is in the reproduction state, or while the hard disk apparatus 2 is recording. Even when another program is played back, the same operation is performed so that the emergency broadcast can be viewed in real time.

In the configuration of the information recording / reproducing apparatus 10 of FIG. 1, the selector 9 is controlled so that the control signal from the emergency broadcast information processing unit 5 is directly input, but it is synchronized with the control of the stream processing unit 4. Then, even if the control unit 1 is configured to perform selective control, the same effect can be obtained.

As described above, according to the information recording / reproducing apparatus in the first embodiment, when the emergency broadcast is received, it can be viewed in real time regardless of the operating state of the information recording / reproducing apparatus.

Second Embodiment FIG. 2 shows a second embodiment of the information recording / reproducing apparatus according to the present invention.
3 is a block diagram showing the configuration of the main part of FIG.

The information recording / reproducing apparatus 15 shown in the figure is different from the video information recording / reproducing apparatus 10 of the embodiment shown in FIG.
The output part of is divided into two systems.

Therefore, in the information recording / reproducing apparatus 15 of the second embodiment shown in FIG. 2, the same or corresponding portions as those of the information recording / reproducing apparatus 10 of the first embodiment shown in FIG. Therefore, the description of the common parts will be omitted, and the different points will be mainly described below.

Generally, information of about 25 Mbit / sec is assigned to one channel, and it is possible to carry a maximum of 8 program TS signals within the range. Generally, when broadcasting a program of normal image quality (480i; 720 × 480 interlaced signal) at the same time, 3 channels per channel
It is possible to broadcast one TS at the same time.

Now, in the stream of the digital signal output from the tuner section 3, three normal image quality (480i)
Of the TS (first TS, second TS, third TS) are being broadcast, and while the hard disk device 2 is recording and watching the program of the first TS among them, It is assumed that the emergency broadcast is started and the emergency broadcast is assigned to the second TS. At this time, the T that is currently being recorded even if the emergency broadcast is started
When the S broadcast is continued, the stream processing unit 4 outputs the first TS and the second TS assigned to the emergency broadcast to the TS / PS converter 16.

At this time, the TS / PS converter 16 uses the first
The first PS signal converted from the TS is output to the hard disk device 2 as an output data signal, and the second PS signal converted from the second TS (at this time, emergency broadcast) is output data signals to the first and the second PS signals. Selector 7, which is a selector of 2,
Output to 9.

Since the selector 7 always selects the output data signal from the TS / PS converter 16 because the recording is being performed, the emergency broadcast is transmitted to the T immediately after the emergency broadcast is started.
Output to V. At this time, the selector 9 which is the second selector outputs the TS of the emergency broadcast to the decoder 8 whichever is selected. On the other hand, since the TS / PS converter 16 outputs the first PS to the hard disk device 2, the program data of the first TS continues to be recorded.

When the emergency broadcast ends, the emergency broadcast information processing unit 5
When it is detected that the emergency bit in the TMCC has been released, the stream processing unit 4 sends only the program data of the first TS to the TS / PS converter 1 according to a command from the control unit 1.
6 is output. At this time, the TS / PS converter 16 uses the first PS as an output data signal from both output sections to output the HDD
2 and selectors 7 and 9 respectively. Therefore, M
Since the PEG decoder 8 converts this first PS into a TV signal, the program of the currently recorded first TS is displayed again on the TV screen.

By the above operation, even if the emergency broadcast is started during the recording of the program, the program can be recorded without hindering the current recording operation, and the emergency broadcast can be viewed in real time.

Next, the operation when the information recording / reproducing apparatus 15 is in the time-free reproduction state described above will be described. In the time free state, as described in the description of the first embodiment, the selector 7 causes the hard disk device 2 to operate.
The reproduced data signal from is selected. At this time also, the program data of the first TS is recorded and reproduced, and the emergency broadcast is assigned to the second TS.

When the emergency broadcast is started while the hard disk device 2 is recording the program data of the first TS, the emergency broadcast information processing unit 5 detects the emergency broadcast bit in the TMCC and performs the stream processing. In the unit 4, the first TS and the emergency broadcast (second TS) are output to the TS / PS converter 16.

At this time, the TS / PS converter 16 uses the first
The first PS signal converted from the TS is output to the hard disk device 2 as an output data signal, and the second PS signal converted from the second TS (at this time, emergency broadcast) is output data signals to the first and second PS signals. Selectors 7, 9 which are selectors of
Output to.

At this time, the selector 9 is set so as to select the emergency broadcast program data which is the output data signal from the TS / PS converter 16 in response to the instruction from the emergency broadcast information processing unit 5, so that the emergency broadcast is performed. Immediately after the start, the emergency broadcast is output to the TV. On the other hand, the hard disk device 2 continues to receive the first P from the TS / PS converter 16.
Since S is output, the program data recording of the first TS is continued. At this time, the control unit 1 issues a command to the hard disk device 2 to pause the reproduction, and the reproduction operation state is changed to the reproduction pause state.

When the emergency broadcast ends, the emergency broadcast information processing unit 5
When it is detected that the emergency bit in the TMCC has been released, the stream processing unit 4 issues a command from the control unit 1 so that only the program data of the first TS is TS / PS converter 1
6 is output. At this time, the TS / PS converter 16 uses the first PS as an output data signal from both output sections to output the HDD
2 and selectors 7 and 9 respectively.

At this time, the hard disk device 2 releases the paused state of reproduction and resumes the reproduction operation in response to a command from the control unit 1, and the selector 9 receives a command from the emergency broadcast information processing unit 5 again. The output signal from the selector 7 is selected. Therefore, the MPEG decoder 8 converts the reproduction data signal of the hard disk device 2 into a TV signal,
On the TV screen, the program of TS1 which is the restarted reproduction data signal of the hard disk device 2 is displayed without being cut.

Although the above description is for the operation during time-free reproduction, the hard disk device 2 performs at least one recording operation and at least one reproduction operation at the same time, not only in the above-mentioned time-free reproduction state. If so, it is applicable to all.

As described above, according to the information recording / reproducing apparatus 15 of the second embodiment, the emergency broadcast can be viewed in real time, and continuously broadcast programs can be recorded in the hard disk device 2. Is possible. Furthermore, in the case of time-free playback, playback is paused during emergency broadcast, and playback is resumed when the program broadcast is resumed, so continuously recorded programs are delayed by the emergency broadcast time. It is possible to watch without omission at the timing.

Third Embodiment Next, an information recording / reproducing apparatus according to a third embodiment of the present invention will be described. Since the information recording / reproducing apparatus of the third embodiment is structurally the same as the information recording / reproducing apparatus 15 of the second embodiment shown in FIG. 2, its operation will be described below with reference to FIG.

In the second embodiment, the operation in the case where one of a plurality of programs in the same channel is assigned to the emergency broadcast has been described. However, for example, when the high-definition broadcast is performed, the BS digital broadcast 1 is generally used. It is broadcast using the full amount of information allocated to the channel. Therefore, only one TS can be broadcast on one channel, and emergency broadcasting cannot be performed unless the program currently being broadcast is interrupted.

HDTV broadcast to hard disk device 2
When the emergency broadcast is started during recording in step 1, the emergency broadcast is output to the TS / PS converter 16. At this time, TS
The / PS converter 16 outputs the same emergency broadcast program data from both output sections to the hard disk device 2 and the first and second selectors 7 and 9 as output data signals.

At this time, the selector 7 always selects the output data signal from the TS / PS converter 16 because the hard disk device 2 is recording. Therefore, MPEG
The decoder 8 converts the emergency broadcast program data of the output data signal from the TS / PS converter 16 into a TV signal and outputs it to the TV.

By the above operation, when the emergency broadcast is started, the emergency broadcast is output to the TV, so that the viewer can watch the emergency broadcast in real time.

On the other hand, to the hard disk device 2, at the same time when the emergency broadcast is started, the control section 1 issues a command to suspend the recording operation, and the recording is suspended. Therefore, this emergency broadcast is not recorded in the hard disk device 2.

When the emergency broadcast ends, the emergency broadcast information processing unit 5
When it is detected that the emergency bit in the TMCC has been released, the stream processing unit 4 outputs the TS before interruption to the TS / PS converter 16 in response to a command from the control unit 1. Further, the control unit 1 issues a command to the hard disk device 2 to cancel the recording suspension, and the recording is restarted. Since the states of the selector 7 and the selector 9 are not particularly changed, the resumed program is displayed on the TV screen.

Therefore, even when the recorded program is interrupted by the emergency broadcast, it becomes possible to continuously record only the target program without recording the emergency broadcast in the hard disk device 2. .

When an emergency broadcast is detected when the information recording / reproducing apparatus is in the time-free reproduction state, the selector 9 is switched to change the TS / PS converter 16 as in the case of the second embodiment. The emergency broadcast program data of the output data signal from is converted into a TV signal and output to the TV. Then, the recording operation of the hard disk device 2 as well as the reproducing operation are suspended. This allows the viewer to watch the emergency broadcast in real time.

On the other hand, when the emergency broadcast ends, the hard disk device 2 releases the pause of recording and reproduction by the command from the control unit 1 and restarts each recording / reproduction operation.
The selector 9 selects the output signal from the selector 7 again according to the instruction from the emergency broadcast information processing unit 5. Therefore, since the MPEG decoder 8 converts the reproduction data signal of the hard disk device 2 into a TV signal, the resumed TS program which is the reproduction data signal of the hard disk device 2 is displayed on the TV screen without being cut. It

The above description applies to the case where the high-definition broadcast is interrupted, but it applies to all cases where the currently recorded program is interrupted by the emergency broadcast.

As described above, according to the information recording / reproducing apparatus of the third embodiment, an emergency broadcast can be viewed in real time regardless of the operating state of the information recording / reproducing apparatus, and the hard disk device can , It becomes possible to continuously record only a target program without recording an emergency broadcast.

In each of the above-described embodiments, an example in which a hard disk device is used as a recording / reproducing device has been described, but the present invention is not limited to this, and is applicable to all recording / reproducing media at a desired rate. It is what is done.

[0062]

According to the information recording / reproducing apparatus of the first and second aspects, even when the information recording / reproducing apparatus is in any state, when the emergency broadcast is received, it can be viewed in real time.
