Video file distribution method and video file distribution system

Abstract

The invention provides a video file distribution method. A video file comprises a low frequency essential data layer and at least one high frequency detail data layer after layered coding. The video file distribution method is characterized in that the transmission efficiency of a distribution network can be determined; the distribution level of the video file can be determined by comparing the transmission efficiency with a predetermined efficiency / distribution level model; the video file is distributed based on the determined distribution level of the video file; the residual distribution levels of the predetermined efficiency / distribution level model are corresponding to the distribution of the combination of the low frequency essential data and at least one high frequency detail data layer of the video file after the layered coding. The invention also provides a video file distribution system. According to the current network quality, the video files can be transmitted according to different distribution levels, the video definition can be adjusted in a self-adapted manner according to the condition of the network quality, and therefore the storage space can be greatly reduced, the scheduling quantity can be reduced, and the user experience can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a method and system for distributing video files. Background technique [0002] With the rapid development of network technology, the amount of network data that integrates multi-bit rate codecs such as data, voice, and video is increasing rapidly. Due to the difference in network transmission bandwidth, generally high bit rate video files need to use a wider bandwidth, while low bit rate videos occupy a small amount of bandwidth. [0003] Currently, for different bandwidths, a certain video file (for example, the file size is 1G) is transcoded into multiple copies with different bit rates. For example, high-bit-rate video files (that is, high-definition video files, the video screen display is very clear, and its file size is 1G), ordinary bit-rate video files (plain-definition video files, the video screen displays general clarity, and its files The ...
