摘要： A method is provided for enhancing a legacy satellite digital radio audio service (SDARS) by overlaying a hierarchically modulated data stream on a base layer (legacy) data stream and improving the synchronization of the received signal in which an overlay layer frame is synchronized to a base layer frame. The base layer frame includes additional data that is used to synchronize the receivers to demodulate and decode the overlay layer and the base layer. The additional data is modulated using a technique that aids the receiver in synchronizing the received signal that is different from the overlay layer.

摘要： Systems and methods for increasing bandwidth for digital content delivery are presented. A content delivery method and system split a digitally encoded content file (e.g., song, television show, movie, podcast, or other audio or video content file) to be delivered to receivers into at least two files with a first file being stored at a receiver in advance of receiving the second file. The first file generally includes a majority of the information in the content file but is denatured and cannot be decoded by a receiver or media player to produce even a portion of the original content file without the second file. The second file includes information derived from the original content file that is not contained in the first file. Upon receiving the transmitted second file, a receiver combines and processes both files to recover the original content file wholly or substantially for playback.
摘要翻译：提出了增加数字内容传送带宽的系统和方法。内容传送方法和系统将要传送到接收器的数字编码内容文件（例如，歌曲，电视节目，电影，播客或其他音频或视频内容文件）分割成至少两个文件，其中第一文件被存储在接收器提前接收第二个文件。第一文件通常包括内容文件中的大部分信息，但是变性，并且不能被接收器或媒体播放器解码以产生甚至一部分原始内容文件而没有第二文件。第二个文件包括从原始内容文件导出的信息，该文件不包含在第一个文件中。在接收到所发送的第二文件之后，接收器组合并处理这两个文件以完全或基本上用于回放的原始内容文件。

摘要： A method is provided tor enhancing a legacy satellite digital radio audio service (SDARS) by overlaying a hierarchically modulated data stream on a base layer (legacy) data stream to increase the amount of data transmitted in the SDARS system. Using improved (next generation) receiver designs, additional services can be provided to users while existing legacy receivers can continue to receive the services broadcast on the base layer modulated data stream in the legacy system.
