LIVE TIMING FOR DYNAMIC ADAPTIVE STREAMING OVER HTTP (DASH)

摘要

In one example, a client device for receiving information for streaming of media data includes a clock, and one or more processors configured to receive a media presentation description (MPD) for media content, wherein the MPD includes data indicative of wall-clock times at which the client device can retrieve data of the media content from a source device, and wherein the data indicates a synchronization method by which the client device is to synchronize the wall-clock times with the clock, synchronize the clock with the wall-clock times using the method indicated by the MPD, and request data of the media content from the source device using the synchronized clock. A server device or source device may form and provide such an MPD to a client device.
