Video processing method and device

Abstract

An embodiment of the present invention provides a video processing method and device, the video processing method includes: the first device refers to the codec unit that can be correctly decoded by the second device in the reference image buffer of its own encoder, and converts the original video data The codec unit or the decoded codec unit is encoded as a P or B type codec unit; the codec unit includes a frame or a macroblock; the first device sends the coded codec unit to the second device. In the embodiment of the present invention, the first device re-encodes video data whose received type includes I and P (optionally including B) type frames or macroblocks, uses P or B type as much as possible in the re-encoding process, and then encodes The final video data is sent to the second device, so that bandwidth resources occupied by the video data can be reduced, and user experience can also be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a video processing method and device. Background technique [0002] With the development of communication technology, the application of video in mobile network is more and more extensive. However, while video services provide rich information, they also occupy most of the system bandwidth and become a great pressure on operators, especially for mobile operators. Due to limited bandwidth, video services are likely to cause mobile network congestion, degrade video user experience, and affect other voice / data users. [0003] In existing video coding formats, there is a distinction between intra-coded frames and inter-frame coded frames. The intra-frame coded frame is an independently coded image, and the receiving end does not depend on other frame decoding; while the decoding of the inter-frame coded frame at the receiving end needs to rely on the previ...

Problems solved by technology

[0004] However, for IPPP... (or some coded as B frames in the middle) video data at intervals of I frames, there is a problem that the amount of video data is too large, it takes up more bandwidth resources, and the user experience is not good.

In addition, for I macroblocks, some current practices are to randomly insert I macroblocks in P frames or B frames to reduce the impact of transmission errors; however, these randomly inserted I macroblocks are Unnecessary, there is also the problem of occupying more bandwidth resources, and the corresponding user experience is not high
