Problems solved by technology

[0002] With the popularity of instant messaging and the improvement of network bandwidth, more and more network users use cameras for video chatting. However, due to the instability of network bandwidth and transmission quality, it is difficult to guarantee the quality of video chatting in instant messaging. Video blurring and mosaic phenomena caused by out-of-sequence and packet loss are one of the current bottlenecks in video communication quality
[0003] In the prior art, after receiving the video data packets, the receiving end sorts the data packets to solve the problem of out-of-order data packets, but still does not solve the problem of packet loss. If there is packet loss in the video, it will still cause Flower screen or mosaic phenomenon
[0004] For example, the video sequence encoded by the sending end according to the H.264 encoding technology is IPPPPP IPPP. If the second I frame is lost during video data transmission, in this case, the video sequence received by the receiving end is IPPPPP PPP, the sequence sent to the decoder for decoding is also IPPPPPPPP. At this time, due to the loss of the I frame reference frame, the subsequent P frame can only be used as a reference from the first I frame, resulting in mosaic or blurred screen phenomenon

Abstract

The embodiment of the invention provides a video data decoding method and device, and the method and device are used in the Internet of scenes. The method comprises the steps: receiving a video sequence sent by a node server, wherein the video sequence comprises an intraframe coding frame; and judging whether packet loss happens to the intraframe coding frame or not: abandoning the video sequence if the packet loss happens to the intraframe coding frame, or else, carrying out the decoding of the intraframe coding frame. According to the embodiment of the invention, the method guarantees the integrity of the video sequence, and avoids the mosaic phenomenon during video playing.
