Abstract: Techniques are described for synchronizing multiple time-based data streams with independent clocks wherein relationships between clock rates of timing devices associated with the time-based data streams are determined, and based on these relationships, times in at least one of the time-based data streams may be translated to times in any of the other time-based data streams despite the data streams having independent clocks.

Abstract translation: 描述了用于使多个基于时间的数据流与独立时钟同步的技术，其中确定与基于时间的数据流相关联的定时装置的时钟速率之间的关系，并且基于这些关系，基于时间数据中的至少一个的时间 尽管数据流具有独立的时钟，流可以被转换成任何其他基于时间的数据流中的时间。

Abstract: Systems and methods are disclosed for the rendering of contents communicated between devices. A source device processes a video sequence and transmits it to a target device together with metadata including rendering directives. At the target device, the received video sequence is rendered according to the rendering directives. Rendering is affected by events detected by the target device at the time of rendering or by the target device's information. Transparency masks, generated by the source device, are transmitted in an alpha channel to the target device, and are used for blending the video sequence with a secondary content.
