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. The method includes the following steps: configuring a start shadow register for an encoder, and judging the start position of a current video frame according to a pre-start signal of the start shadow register ; Configure the encoding enable register, judge the current code stream form according to the enabling signal of the encoding enabling register; configure the storing enabling register, store the encoding unit of the fixed row in the internal memory, and store according to the storing of the storing enabling register Enable the signal to store the code stream of the corresponding form; judge the current code stream form to be encoded according to the code stream channel selection signal, configure the encoding priority, and judge the code stream form of the next encoding unit to be encoded after completing the storage of the current encoding unit . By changing the address mapping, the method and system can realize the circulation of one frame of requested data in a limited space to realize rolling storage, which can save memory and improve the utilization rate of memory.
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...
