[0059] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0060] The present invention starts from two aspects of bit error concealment and bit error diffusion suppression, combines the error bit concealment strategy of the receiving end and the bit error diffusion suppression strategy of the sending end, so as to reduce the video quality loss caused by bit errors as much as possible and avoid error The code causes the purpose of diffusion. For bit error concealment, a simple alternative can be used to achieve the effect of compensating bit error losses with as little complexity as possible; for bit error diffusion suppression, an error information feedback mechanism is established through the existing channels of H.264, and the frame is implemented according to the feedback. Intra-coding to achieve the effect of diffusi...
