摘要： A wireless communication apparatus in a hierarchically coded modulation system can use error control mechanisms generated during decoding of base layer information to predict a probability of successful demodulation of enhancement layer information. Performance in the demodulation of the base layer correlates to performance in the demodulation of the enhancement layer. The receiver can determine whether to attempt demodulation of temporally correlated enhancement layer data based in part on the predicted probability of success. If the receiver determines not to demodulate the enhancement layer, the receiver can power down the enhancement layer demodulator, or otherwise minimize the power expended in the enhancement layer demodulator.

摘要： Techniques to seamlessly switch reception between multimedia programs are described. For “continued decoding”, a wireless device continues to receive, decode, decompress, and (optionally) display a current program, even after a new program has been selected, until overhead information needed to decode the new program is received. After receiving the overhead information, the wireless device decodes the new program but continues to decompress the current program. The wireless device decompresses the new program after decoding this program. For “early decoding”, the wireless device receives a user input and identifies a program with potential for user selection. The identified program may be the one highlighted by the user input or a program anticipated to be selected based on the user input. The wireless device initiates decoding of the identified program, prior to its selection, so that the program can be decompressed and displayed earlier if it is subsequently selected.
摘要翻译：描述了在多媒体节目之间无缝切换接收的技术。对于“继续解码”，即使在选择了新的程序之后，无线设备继续接收，解码，解压缩和（可选地）显示当前程序，直到接收到解码新程序所需的开销信息。在接收到开销信息之后，无线设备解码新程序，但是继续解压缩当前程序。解码该程序后，无线设备解压缩新程序。对于“早期解码”，无线设备接收用户输入并识别具有用户选择潜力的节目。识别的程序可以是由用户输入或预期将基于用户输入选择的程序突出显示的程序。无线设备在其选择之前启动所识别的节目的解码，使得如果随后选择该节目，则可以更早地解压缩并显示节目。

摘要： This disclosure describes a number of techniques for processing multimedia data that can improve multi-program “picture-in-picture” viewing, particularly in a wireless mobile apparatus setting. In one example, a method includes receiving multiple channels of the multimedia data, decoding frames associated with two or more of the channels, presenting first frames of a first channel at a first frame rate, and presenting second frames of a second channel at a second frame rate while presenting the first frames, wherein the second frame rate is lower than the first frame rate. In another example, method includes receiving multiple channels of the multimedia data, receiving channel switch frames (CSFs) associated with the multiple channels, and simultaneously presenting the CSFs associated with two or more of the multiple channels to a user.
