[0002] In the live signal broadcasting system, there is a mosaic navigation system, sometimes called channel 0, which is expressed in the form of synthesizing multiple live signals into another live signal, which is treated as an indistinguishable live signal when played on the terminal to play, there are many limitations in experience
[0003] When it is necessary to select a sub-picture for presentation, the traditional method is to obtain a live signal in the target display area when the user pays attention to (such as focus selection) a sub-picture, and the effective picture cannot be presented in the target area before the acquisition , poor experience

Embodiment Construction
[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is only some embodiments of the present invention, but not all embodiments.
[0030] see figure 1 , which is a flow chart showing the steps of the multi-picture signal playback method according to the embodiment of the present invention, which includes the following steps:
[0031] S101. Receive a multi-picture signal, and obtain a sub-picture B that the user pays attention to;
[0032] S102, decode the video picture into a first video picture A;
[0033] S103, judging whether the first video picture has used the original signal of the user-focused sub-picture B,
[0034] If yes, proceed to the following steps S104 to S108...

The embodiment of the invention discloses a multi-image signal playing method. The method comprises the steps of receiving a multi-image signal and obtaining a sub-image B concerned by a user; decoding a video image into a first video image A; judging whether the first video image employs an original signal of the sub-image B concerned by the user or not; if the first video image employs the original signal of the sub-image B, pulling the original signal corresponding to the sub-image B concerned by the user; analyzing the original signal; decoding a video signal into a first original image M; scaling the first original image M according to a target area to obtain a first scaled original image N; synthesizing the first scaled original image N into the target area again to form a new first image K; marking the first image K as an initially employed original signal; rendering the new first image K to a screen; and synchronously playing an audio corresponding to the sub-image B concerned by the user.
Description
technical field [0001] The invention relates to the technical field of video coding, in particular to a method for playing multi-picture signals. Background technique [0002] In the live signal broadcasting system, there is a mosaic navigation system, sometimes called channel 0, which is expressed in the form of synthesizing multiple live signals into another live signal, which is treated as an indistinguishable live signal when played on the terminal To play, there are many limitations in experience. [0003] When it is necessary to select a sub-picture for presentation, the traditional method is to obtain a live signal in the target display area when the user pays attention to (such as focus selection) a sub-picture, and the effective picture cannot be presented in the target area before the acquisition , poor experience. [0004] see figure 1 , which is shown as a multi-picture signal synthesized by the method of Chinese invention patent application CN201610568959.4, ...
