Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.

Abstract translation: 管理通信会话到在辅助无线设备的直接连接与经由主无线设备到辅助无线设备的中继连接之间切换的方法和设备。 辅助无线设备的连接管理器可以基于通信会话的性能度量的测量来触发通信会话的传送。 在检测到本地连接或回程连接或两者之间的性能下降时，辅助无线设备的连接管理器可以确定主无线设备的连接的接近度和/或能力，并且促使不同连接类型之间的通信会话的传送 ，例如在直接连接和中继连接之间。 通信会话的传送可以在没有用户干预的情况下进行，或者响应于用户的输入而不中断或重新建立通信会话。

Abstract: Techniques are disclosed for coding video data in which frames from a video source are partitioned into a plurality of tiles of common size, and the tiles are coded as a virtual video sequence according to motion-compensated prediction, each tile treated as having respective temporal location of the virtual video sequence. The coding scheme permits relative allocation of coding resources to tiles that are likely to have greater significance in a video coding session, which may lead to certain tiles that have low complexity or low motion content to be skipped during coding of the tiles for select source frames. Moreover, coding of the tiles may be ordered to achieve low coding latencies during a coding session.
