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.

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: Some embodiments of the invention provide novel methods for converting the color region of images. For instance, the method of some embodiments converts the color of an image from one color region (e.g., from a Rec. 601 color region) to another color region (e.g., to a Rec. 709 color region). In some embodiments, the method receives the image in a first color format that is non-linearly encoded within a first color region. Without performing a linearization operation to linearize the color component values of the image, the method then converts the image into a second color format that is defined with respect to a second color region. In some embodiments, the color-converted image is non-linearly encoded in the second color region.
