摘要
提出一种面向客户端带宽与设备受限的视频数据转码方案。首先,获取并存放与视频资源相关的用户感兴趣区域(ROI)元数据。然后,在视频传输阶段,根据客户端的带宽、处理器处理能力、功耗的不同情况,参考ROI信息,将原始视频进行转码。转码后的视频流仍会保持较好的主观观看效果。
This paper proposes a video transcoding scheme oriented the client bandwidth and device limited. Firstly, it acquires and stores the Region of Interest (ROI) metadata. Then, during the video transmitting phase, according to the client bandwidth, ability of processor, the different of power dissipation, the original video is transcoded. The video stream of transcoding remains good sound effects.
