Abstract

The present disclosure relates to a method and system for seamless switching of multiple video streams at a playback end. An example system includes a multi-stream encoder having an encoder controller configured to perform operations. Operations include receiving a plurality of video sources and encoding the video sources to form a plurality of encoded streams. Each of the plurality of encoded streams includes a corresponding primary video source and at least one secondary video source. The system also includes a multi-stream player having a player controller configured to perform operations. Operations include receiving a plurality of encoded streams, receiving a video source selection command indicating a desired video source, and determining a desired encoded stream that includes a high resolution version of the desired video source based on the video source selection command.

Description

technical field [0001] The present disclosure relates to the field of high-definition streaming media transmission, and more specifically, to the field of high-definition streaming media transmission based on user interaction. Background technique [0002] In a traditional video streaming or broadcasting scenario, there are multiple video sources, and for any given time, a viewer can only watch one of them. In traditional broadcasting, most video streams go through a broadcast station where a person (eg, a director) selects one of them to broadcast. [0003] Recent approaches provide each viewer with various ways of selecting which video stream to watch. However, existing methods either cannot ensure time synchronization during a switch, or require significantly more network bandwidth and computing resources on the client side, or require expensive server computing costs in order to provide synchronization. [0004] Therefore, there is a need to provide systems and methods...
