Presentation of cross-platform multimedia content may be controlled by a media player. Cross-platform content may include a two-dimensional (2D) graphics component, a three-dimensional (3D) graphics component, and a video component. Each component may be rendered as a separate layer, and each component may be rendered independently from one another. The multimedia player may synchronize the separate renderings for presentation. In one embodiment, the rendering of at least one of the separate layers may be performed by a hardware resource separate from the hardware resource executing the multimedia player. Each separate layer may be composited for display. In one embodiment, the compositing may be performed by a hardware resource separate from the hardware resource executing the multimedia player.

Independent layered content for hardware-accelerated media playback

In one aspect, a method includes: obtaining compressed video content within a video content processing module, a portion of a document structure of the compressed video content conforming to a predefined codec, the portion of the document structure including a plurality of video frames; decrypting the compressed video content in accordance with a digital rights management data encryption applied to the compressed video content; adding information in an extension frame associated with a portion of the document structure; and applying an encoding technique to content of one or more of the plurality of video frames after the decrypting, wherein the extension frame flags the applied encoding technique; and providing the compressed video content, including the encoded content, to a media player including a codec conforming to the predefined codec.

Protecting video as it is decoded by a codec

A system and method provides video data and its corresponding alpha channel data using a single stream or file, compressed using the same format and decompression algorithm for each of the video data and the alpha channel data.

System and method for compressing video data and alpha channel data using a single stream

Image content may be compressed using a plurality of block truncation coding schemes resulting in a plurality of compressed versions of the image content. The plurality of compressed versions may be combined together into a single data structure. Prior to combining the plurality of compressed versions, each compressed version may be further compressed. In one embodiment, a data structure containing a plurality of block truncation encoded format versions of image content may be received. Rendering hardware-compatible block truncation encoded content from the plurality of compressed versions may be determined and provided to rendering hardware. The hardware may then decode the selected one block truncation encoded format for display. In one embodiment, each of the received plurality of block truncation encoded content versions may be further compressed. Before providing the selected version to the hardware for decoding, the further compression may be decompressed.

Compression of image data

Video content from a layer of multiple multimedia content layers may be moved to a lowest content layer. The region of the multimedia content layer that previously contained the video content may be replaced with a transparent region. Additional layers that exist between the layer from which the video content was removed and the lowest layer may likewise have corresponding regions replaced with transparent regions. The content layers may be composited together at a display time. Accordingly, the video content of the lowest content layer may be viewed through the transparent regions, which may allow the video to be seen as originally authored. The lowest content layer may be rendered independently of other layers. In some embodiments, the content layer containing video may be performed with dedicated hardware (e.g., a GPU).

Accelerating video from an arbitrary graphical layer

A system and method receives video data and its corresponding alpha channel data using a single stream or file, each of the video data and alpha channel data in the same format, and decompresses each set of data using a single decompression algorithm.
