Abstract: |
The invention relates to a method for optimizing the transmission of the wireless video based on proportional integral differential control technology, which includes: Firstly, it initializes. Then, it carries out source encoding about the video, after that, it carries out channel encoding about the source encoded video according to the redundant value. Then, it transmits the video to the terminal. Then, the terminal decodes and broadcasts the video, at the same time, the terminal feedbacks information to server through back channel. Then, the server calculates the dropout rate of the wireless channel and real-time updates the redundant value when the server receives the feedback signal. After that, it encodes the video data according to the updated redundant value, packs it, and sends it out. |
