摘要： Delta compression may be achieved by processing video data for wireless transmission in a manner which reduces or avoids motion estimation by a compression process. Video data and corresponding metadata may be captured at a composition engine. Frame buffer updates may be created from the data and metadata. The frame buffer updates may include data relating to video macroblocks including pixel data and header information. The frame buffer updates may include pixel reference data, motion vectors, macroblock type, and other data to recreate a video image. The macroblock data and header information may be translated into a format recognizable to a compression algorithm (such as MPEG-2) then encoded and wirelessly transmitted.

摘要： In general, this disclosure describes video processing techniques that make use of syntax elements and semantics to support low complexity extensions for multimedia processing with video scalability. The syntax elements and semantics may be added to network abstraction layer (NAL) units and may be especially applicable to multimedia broadcasting, and define a bitstream format and encoding process that support low complexity video scalability. In some aspects, the techniques may be applied to implement low complexity video scalability extensions for devices that otherwise conform to the H.264 standard. For example, the syntax element and semantics may be applicable to NAL units conforming to the H.264 standard.
摘要翻译：一般来说，本公开描述了利用语法元素和语义来支持具有视频可扩展性的多媒体处理的低复杂度扩展的视频处理技术。语法元素和语义可以被添加到网络抽象层（NAL）单元，并且可以特别适用于多媒体广播，并且定义支持低复杂度视频可扩展性的比特流格式和编码过程。在一些方面，可以将这些技术应用于为符合H.264标准的设备实现低复杂度视频可扩展性扩展。例如，语法元素和语义可以适用于符合H.264标准的NAL单元。
