摘要： A system and method for transmitting files from a sender to a receiver in a television distribution system, for example, a cable television distribution network, is provided. The files are transmitted without the need for transmitting a directory over an out of band communications link. In an exemplary embodiment, a filename corresponding to a file to be transmitted is provided to a transform. The transform calculates a PID based on the filename. The calculated PID is incorporated into the MPEG2 data stream carrying the corresponding file contents. When an application program running in the receiver requests a file, the filename of the requested file is provided to a transform operating in the receiver. The transmitter and receiver transforms are identical. The transform provides a corresponding PID at its output. The PID is used to tune a PID filter on the receiver end such that the requested file is selected from the incoming MPEG bit stream for processing by the processor.
摘要翻译：提供了一种用于在电视分配系统（例如，有线电视分配网络）中从发送者到接收者发送文件的系统和方法。传输文件，而不需要通过带外通信链路发送目录。在示例性实施例中，将要发送的文件的文件名提供给变换。该变换根据文件名计算PID。计算的PID被并入携带相应文件内容的MPEG2数据流中。当在接收器中运行的应用程序请求文件时，所请求的文件的文件名被提供给在接收器中操作的变换。发射机和接收机的转换是相同的。该变换在其输出端提供相应的PID。 PID用于调整接收器端的PID滤波器，使得从输入的MPEG比特流中选择所请求的文件以供处理器处理。

摘要： A system and method for transmitting data from a sender (22) to a receiver (28) in a television distribution system, for example, a cable television distribution system (20), is provided. The files are transmitted without the need for transmitting a directory over an out of band communications link (24). In an exemplary embodiment, a filename corresponding to a file (FN1) to be transmitted is provided to a transform (54). The transform calculates a PID based on the filename. The calculated PID is incorporated into the MPEG2 data stream carrying the corresponding file contents. When an application program running in the receiver requests a file, the filename of the requested file is provided to the transform operating in the receiver (28). The transmitter and receiver transforms are identical. The transform provides a corresponding PID at its output. The PID is used to tune a PID filter (88-90) on the receiver end such that the requested file is selected from the incoming MPEG bitstream for processing by the processor (74).
