    Abstract: This disclosure relates to techniques for synchronizing playback of media data between a source device and one or more sink devices in a Wireless Display (WD) system. WD systems enable mobile devices to share a local display of the source device with remote sink devices. The techniques of this disclosure include a management procedure at the source device to select a universal queue size for the source device and the participating sink devices. The source device selects the universal queue size based at least on supported queue sizes of the source device and the sink devices. The media packets are then held in queues having the universal queue size at the source device and the sink devices. The uniform queue size combined with compensation for transmission delay enables each of the devices to begin processing the media packets at the same time.

    Abstract translation: 本公开涉及用于在无线显示（WD）系统中的源设备和一个或多个宿设备之间的媒体数据的重放同步的技术。 WD系统使移动设备能够使用远程宿设备共享源设备的本地显示。 本公开的技术包括在源设备处为源设备和参与宿设备选择通用队列大小的管理过程。 源设备至少基于源设备和宿设备的支持的队列大小来选择通用队列大小。 然后，媒体分组被保持在源设备和信宿设备具有通用队列大小的队列中。 统一队列大小与传输延迟补偿结合使得每个设备能够同时开始处理媒体包。
