Problems solved by technology

On the one hand, real-time live broadcast requirements require the use of real-time streaming media transmission protocols, which are generally based directly on UDP; on the other hand, the requirements for storage integrity require the use of reliable transmission protocols, such as TCP, but TCP will obviously Reduce the real-time performance of video transmission

Embodiment Construction

[0056] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0057] like figure 1 combine Figure 4 As shown, the frame loss control and continuation system in the real-time streaming media upload of the present invention includes two parts: a video acquisition end and a media server end.

[0058] Among them, the video acquisition terminal is used to acquire video scene data in real time, and upload them to the media server in two ways: real-time and continuous transmission, including:

[0059] Video shooting module, used for real-time acquisition of video scene data, marking the pre-playing moment;

[0060] The video sequence identification negotiation module is used for negotiating with the media server to uniquely identify the identification of the video sequence;

[0061] A sending queue detection module is used to detect whether the video frame in the sending queue is located within the sending windo...

Abstract

Disclosed is a system for frame loss control and retransmission in real-time streaming media uploading, which comprises a video obtaining side and a media server side. The video obtaining side is used for obtaining video scene data in real time, and uploading video data frames to the media server side in real-time and retransmission manners. The media server side is used for receiving the real-time and retransmitted video data frames of the video obtaining side, lively broadcasting, storing and merging the video data frames. Also disclosed is a method for frame loss control and retransmission in real-time streaming media uploading. Through the present invention, on one hand, frames are selectively lost through an application layer, and the lost data frames are put into a retransmission queue, so that the real-time transmission of live broadcast is ensured, and the transmission bandwidth is saved; and on the other hand, the data frames in the retransmission queue are retransmitted through a new connection when the network condition subsequently gets better, so that the integrity of the stored video is ensured, thereby improving the quality of video on demand.

Description

technical field [0001] The invention relates to a method and system for frame loss control and continuation transmission in real-time streaming media upload, and belongs to the technical field of network multimedia data transmission. Background technique [0002] Today, there is an increasing demand for real-time live event video information. The on-site information of real-time events can be captured in real time by using professional news shooting equipment or portable shooting equipment such as mobile phones and cameras, and quickly disseminate it to the public. like figure 1 As shown, this type of system usually includes two parts: a video capture end and a media server end. The video capture end uploads the real-time captured content to the media server in time, and broadcasts live to interested user groups through the media server. At the same time, the media server must also store the video captured in real time, on the one hand as a backup, and on the other hand to...
