Abstract: A video coding method includes: obtaining a first video file and a second video file that are different; separately decoding the first video file and the second video file to obtain first information of a first image block in the first video file and second information of a second image block in the second video file; obtaining, based on the first information and the second information, difference information indicating a difference between the first information and the second information; and encoding the difference information to obtain encoded data. The difference information may be used to replace an original decoding result in the second video file. It is equivalent to reducing storage resources for video storage and bandwidth for video transmission while ensuring that the complete second video file can be restored.

Abstract: The present invention discloses an inter-frame predictive coding method and a coder. Inter-frame predictive coding is sequentially performed on frames in multiple groups of pictures by using a group of pictures as a unit; a correlation between the reference B frame and a GPB frame in the same group of pictures is used; and when the maximum depth of the CTU in the same position in the GPB frame is smaller, a quantity of mode decisions performed on the CTU in the reference B frame may be relatively small, so that an objective of reducing complexity of an inter-frame predictive coding process of the reference B frame is achieved.

Abstract: A data interaction method is provided, which includes: sending simultaneously an address detection request for a UDP channel and an address detection request for a TCP channel; and when both address detection for the UDP channel and address detection for the TCP channel fail, sending an address detection request for an HTTP channel; when detection of at least one channel succeeds, collecting two types of addresses corresponding to each channel in the at least one channel; performing address exchange and address matching with a peer client host; and performing channel connectivity detection based on matched addresses, and selecting a channel with a highest priority from channels on which connectivity detection is successful for data interaction with the peer client host. Therefore, efficiency of traversing a NAT host during address detection is improved.
