Its application is focused on the NGB TVOS  which is more popular currently.
We found that the film sometimes pause the problem, in the actual implementation of audio and video for real-time wireless transmission and playback. The reason for the analysis is that the image changes from the low frequency and the more inter-frame redundant image of the fragment directly into the high frequency and the less inter-frame redundant image of the fragment.
In order to understand the efficiency of the bitrate control on the wireless transmission, the experiment is divided into three parts, the bitrate control of JVT; the bitrate control of a buffer control and NO bitrate control, explore the benefits of the three different approaches.
The empirical study found that the bitrate control of the buffer control method, can improving the two consecutive images of dramatic changes, resulting in a single image of the bitrate will be a big change. The total bitrate exceeds the set value, affecting the wireless transmission cannot instantly transmit video to pausing of the problem.
