Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a flowchart illustrating a method for adjusting video playback sharpness according to an exemplary embodiment of the present invention, where the method includes the following steps:
step S101, acquiring the playing attribute of the video being played, the playing attribute of the set-top box, the playing attribute of the display device and the network bandwidth.
In the embodiment of the invention, in order to provide better video playing experience for users, the set top box for adjusting video playing definition acquires the playing attribute of the video being played, the playing attribute of the set top box, the playing attribute of the display device and the network bandwidth. The playing attributes of the video include, but are not limited to: the code rate of the video, the resolution of the video, and the playing attributes of the set-top box include, but are not limited to: the current output resolution of the set-top box, the maximum output resolution of the set-top box, and the playing attributes of the display device include, but are not limited to: the maximum output resolution of the display device, the network bandwidth, is the speed of the network the user is using.
The method for acquiring the playing attribute of the display device comprises the following steps: the method comprises the steps of obtaining extended display identification data EDID of display equipment through a direct digital control DDC channel of the HDMI, and obtaining playing attributes of the display equipment according to the EDID.
The network bandwidth can be obtained by measuring through measuring software, the playing attribute of the video can be obtained by analyzing the video through analyzing software, the playing attribute of the set top box is stored locally in the set top box, and the set top box can be obtained by directly calling local information.
And S102, comparing the playing attribute of the set top box, the playing attribute of the display equipment and the network bandwidth with the playing attribute of the video respectively, and adjusting the video according to the comparison result.
In the embodiment of the present invention, what affects the video playing effect is generally the relationship between the code rate of the video and the network bandwidth, and the relationship between the resolution of the video and the resolution of the terminal and the resolution of the display device, and the played video is adjusted according to the above relationship.
The comparing the playing attribute of the set top box, the playing attribute of the display device and the network bandwidth with the playing attribute of the video respectively, and adjusting the video according to the comparison result includes:
comparing the network bandwidth with the code rate of the video, if the network bandwidth is higher than the code rate of the video, adjusting the video to a higher definition film source, and if the network bandwidth is lower than the code rate of the video, adjusting the video to a low definition film source; and/or the presence of a gas in the gas,
and respectively comparing the resolution of the video with the playing attribute of the terminal and the playing attribute of the display device, counting the conditions of the resolution of the video, the current output resolution of the set top box, the maximum output resolution of the set top box and the maximum output resolution of the display device if the resolution of the video is higher than the playing attribute of the set top box, and increasing the output resolution of the set top box if the current output resolution of the set top box is lower than the resolution of the video and lower than the maximum output resolution of the set top box so as to enable the output resolution of the set top box to be matched with the resolution of the video.
When playing network video, the factors influencing the playing definition are mainly the network bandwidth and the code rate of the video. When the network bandwidth is larger than the video code rate, the video can be smoothly played. Otherwise a stuck occurs. We can make a corresponding relationship between the network bandwidth and the video bitrate. For example, under the network bandwidth of 10Mbps, the video with the maximum bitrate of 8Mbps can be played, and the definition of the video is generally 720P or 1080P. When the user plays the video, the downloading speed can be calculated by monitoring the downloading size of the video file in unit time, so that the network bandwidth for playing the video can be known. And simultaneously analyzing the code rate for playing the video. The code rate of the video and the network bandwidth are combined, and whether the network bandwidth meets the requirement of smooth playing of the video can be judged. According to the corresponding relationship between the network bandwidth and the video code rate, it can also be determined that the network bandwidth can support the maximum code rate. Because the video packaging types and the compression ratios are different, the relationship between the bandwidth and the video fluency can be judged by some auxiliary methods. For example: and recording the pause times of playing the video in unit time, the size of a video buffer area and the like to know the smoothness degree of playing the current video. Judge equipment connection type, under the circumstances that wifi connects, the bandwidth can change in real time because of factors such as interfering signal, and it is more stable to cause the card pause under this kind of circumstances and can indicate the user to change wired connection. The auxiliary method can assist in judging the bandwidth and the video fluency to some extent, and the methods are also expected to fall into the invention.
In combination with the definition and output resolution (i.e., Vout _ now) of the video being played, it is possible to know whether the currently played video is output to the maximum extent. For example, the definition of a currently played video is 1080P, but the output resolution is only 480P, so that the content in the video cannot be displayed point to point, and the situation that the video is blurred due to output pixels is reduced.
According to the embodiment of the invention, the playing attribute of the video being played, the playing attribute of the set top box, the playing attribute of the display device and the network bandwidth are acquired, the playing attribute of the set top box, the playing attribute of the display device and the network bandwidth are respectively compared with the playing attribute of the video, and the video is adjusted according to the comparison result, so that the playing definition of the video can be comprehensively adjusted by the set top box according to the use environment of a user, and the best video watching experience allowed by the environment is provided for the user.
As an optional embodiment of the present invention, before the step of adjusting the video according to the result of the comparison, the method further comprises:
and displaying a video adjusting option on the display equipment so that a user can select whether to adjust the video definition according to the video adjusting option.
In the embodiment of the invention, when the video definition needs to be adjusted, the set top box does not default to adjust the video, but displays the adjustment option on the display equipment, and a user can determine whether to adjust the video or not and what definition to adjust through the motor adjustment option.
