Problems solved by technology
[0002] In the existing video coding technology, the coding of real-time video needs to pre-code 2 frames of images, and then perform alternate coding through ping-pong operations. However, the above-mentioned existing video coding technology has the following technical problems: 1. It cannot be realized by using the memory space of limited rows Rolling storage and correct encoding, which wastes storage space; 2. Wastes encoding time, unable to meet the time-division multiplexing to complete the encoding of multiple streams within the time required to store a frame of main stream

The invention discloses a multi-channel video time division multiplexing encoding method and system, and the method comprises the following steps: configuring a starting shadow register for an encoder, and judging the starting position of a current video frame according to a pre-starting signal of the starting shadow register; configuring a coding enabling register, and judging a current code stream form according to an enabling signal of the coding enabling register; configuring a storage enabling register, storing the coding units of the fixed rows in a memory, and storing code streams in corresponding forms according to storage enabling signals of the storage enabling register; judging a current to-be-coded code stream form according to the code stream path selection signal, configuring a coding priority, and judging a to-be-coded code stream form of the next coding unit after the storage of the current coding unit is completed. According to the method and the system, through changing address mapping, one frame of request data can be circulated in a limited space so as to realize rolling storage, the memory can be saved, and the utilization rate of the memory can be improved.
Description
technical field [0001] The invention provides the technical field of video coding, and in particular relates to a multi-channel video time-division multiplexing coding method and system. Background technique [0002] In the existing video coding technology, the coding of real-time video needs to pre-code 2 frames of images, and then perform alternate coding through ping-pong operations. However, the above-mentioned existing video coding technology has the following technical problems: 1. It cannot be realized by using the memory space of limited rows Rolling storage and correct encoding, thereby wasting storage space; 2, wasting encoding time, unable to meet the time-division multiplexing to complete the encoding of multiple streams within the time for storing one frame of main stream. Contents of the invention [0003] One of the objectives of the present invention is to provide a multi-channel video time-division multiplexing encoding method and system. The method and sy...
