Decoding method, coding method, code stream transmission method, electronic equipment and system

Abstract

The invention relates to the technical field of data transmission, in particular to a decoding method, a coding method, a code stream transmission method, electronic equipment and a system, and the decoding method comprises the steps: obtaining the resolution of at least two paths of target code streams; according to the resolutions of the at least two paths of target code streams, determining target sub-pictures in one-to-one correspondence with the resolutions of the at least two paths of target code streams from a canvas corresponding to a target analog signal path; and decoding the corresponding target code stream based on each target sub-picture to obtain at least two paths of target analog code streams, the target analog signal path being used for transmitting the at least two paths of target analog code streams. The target sub-picture is determined from the corresponding canvas in the target analog signal path by utilizing the resolution of the target code stream, and the target code stream is decoded by utilizing the target sub-picture, that is, the same analog signal path is divided into a plurality of sub-pictures to be transmitted simultaneously, so that the use of equipment in a transmission system is reduced, and the deployment complexity of the transmission system is simplified.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to methods for decoding, encoding, and code stream transmission, electronic equipment and systems. Background technique [0002] Massive audio and video surveillance image information has become a necessary resource and means for target supervision. While the private network carrying these audio and video resources brings efficiency and convenience to the daily work of various departments, it also brings serious computer security problems. [0003] For example, when the audio and video code stream of the private network monitoring system needs to be transmitted to the public network, digital-to-analog conversion is required to decode the digitally coded code stream into an analog signal, and transmit it to the encoder of the public network monitoring system through the analog signal line , the encoder of the public network monitoring system is re-encoded into a cod...
