Abstract:
Disclosed a method and a system for providing virtual reality (VR) video transcoding and broadcasting. The method comprises: obtaining a use's viewport; processing a VR video data into a basic video set and an enhancement video set in accordance with the user's viewport, wherein the basic video set comprises a plurality of basic video segments, the enhancement video set comprises a plurality of enhancement video segments, and the playback effect of the sum of the basic video segment and the enhancement video segment is better than that of the basic video segment; downloading the basic video segments and the enhancement video segments; and displaying a sum of two video data obtained by adding the basic video segments and the enhancement video segments in accordance with the user's viewport. According to the embodiments of the present disclosure, the VR video data is processed into a basic video set and an enhancement video set and an video data obtained by adding the basic video segments and the enhancement video segments in accordance with the user's viewport is displayed. Thus, viewing experience is ensured while downloaded data is reduced and transmission effect is improved.

Claim (Index 14):
The system according to  claim 13 , further comprises: a mapping table generating unit configured to obtain a plurality of combinations of resolution and bitrate, wherein each of the plurality of combinations comprises a basic resolution, an enhancement resolution, a basic bitrate and an enhancement bitrate.\n the processing unit comprises: processing a VR video data into the basic video set and the enhancement video set in accordance with the plurality of combinations of resolution and bitrate.
