Problems solved by technology

However, for ultra-high-definition video live broadcast, especially for ultra-high-definition video with high resolution, high bit rate and high video frame rate, the I frame in the GOP data may be very large. When live broadcasting data, even if the first frame of data sent is I frame data, it may take a long time for the live broadcast end to receive the first frame of data, res

Abstract

The invention provides a fast broadcast starting method and apparatus of high-definition live video, and relates to the technical field of live video. The method comprises the following steps: receiving live video data from a live broadcast source in real time, performing parsing according to the currently received live video data, determining a live broadcast parameter of the live broadcast source, caching live broadcast cache data according to the live broadcast parameter and the currently received live video data, and quickly sending the live broadcast cache data to a live broadcast terminal, so that the live broadcast terminal can quickly start broadcasting the live broadcast cache data. The shortest cache time length of the live broadcast cache data needing to be cached at present iscalculated according to the live broadcast parameter and a predetermined algorithm, and the live broadcast cache data are automatically updated in real time according to the shortest cache time lengthand a complete GOP requirement. The live broadcast cache data with the shortest cache time length are met, and the phenomenon that the screen is blocked or the delay is too long after the broadcast is started is reduced; and furthermore, the live broadcast cache data are sent to the live broadcast terminal according to a fast sending speed, thereby improving the broadcast starting speed of the live broadcast terminal, and accordingly, the user placing experience is improved.

Description

technical field [0001] The present invention relates to the technical field of live video broadcasting, in particular to a method and device for quickly starting an ultra-high-definition video live broadcasting. Background technique [0002] In recent years, with the rapid development of video codec technology and screen display technology, people's pursuit of video playback experience is getting higher and higher. The mainstream TV screen size has gradually developed from 40 inches to 55 inches, 60 inches, 70 inches, and even 100 inches. More inches, large screens have higher and higher requirements for video resolution. 1080P (1920*1080) high-definition video can no longer meet the requirements of large-screen playback and display, and ultra-high-definition video has become the standard configuration for large-screen playback and display; At the same time, ultra-high-definition video brings people the ultimate high-definition visual enjoyment, and is becoming more and more...
