Abstract

The invention provides a code stream sending device, a code stream sending method and a code stream sending system. The method comprises the steps: adopting a first main control chip at the code stream sending device side to process communication control information, adopting a first code stream processing chip to process a code stream request, and employing two independent buffer queues; arranging a first buffer queue in a first main control chip, and arranging a second buffer queue in a first code stream processing chip, so a code stream request is completely separated from other communication control information, wherein the first main control chip only needs to pay attention to processing of the communication control information in the first buffer queue; the first code stream processing chip only needs to pay attention to processing of the code stream request in the second buffer queue, and the problem that a processing thread of the first main control chip cannot process the codestream request in time due to processing of the communication control information is avoided; after the code stream request is separated from other communication control information, the response tothe latter does not cause the former to be delayed in response, so the quick response to the code stream request can be completely ensured.

Description

technical field [0001] The present invention relates to the technical field of code stream transmission, in particular to a code stream sending device, a code stream sending method and a code stream sending system. Background technique [0002] In the audio and video distributed system, the video code stream data is transmitted from the sending end to the receiving end, and then the receiving end transmits the video code stream data to the display screen for display. When the receiving end switches the signal source video, it essentially sends a code stream request to the sending end. If the receiving end and the sending end have too much protocol interaction for the code stream request or the sending end processes the request for the receiving end too slowly, it will cause the sending end to fail. The video cannot be quickly displayed on the display screen, which is manifested by the slow response of opening the window on the large screen and slow call of the plan. [0003...
