Method and apparatus for communicating different types of data in a data stream
First Claim
1. A method for transmitting different types of data in a single data stream comprising the steps of:
- generating digital data for insertion into a data stream, said digital data including digital data representative of at least one of games and software;
generating a first type of data for insertion into said data stream;
generating a second type of data for insertion into said data stream;
combining said digital data with said fast type of data to form mixed data groups;
generating a header containing data from said second type of data;
combining said header with said mixed data groups to form a data frame; and
constructing said data stream by joining a plurality of successive data frames for transmission.

Abstract
An apparatus and method is described for transmitting, receiving and communicating program data signals which are combined with digital data signals. Preferably, the present invention compresses 30 digital audio signals, multiplexes them with title, track, artist, record label, year, etc., program information, and transmits the combined signals via satellite to a receiving station. The receiving station demultiplexes the signals and sends them via a cable distribution system to a subscriber'"'"'s digital music tuner. This tuner further demultiplexes and decodes the signals so that the digital audio signals may be converted to analog and output for listening, while the corresponding data signals are communicated to the subscriber. In an alternative preferred embodiment, the program data signals are transmitted to a remote control receiver where they are displayed. The system described in the present invention may be used for transmitting video, software or games with program data to subscribers.

11. A digital data receiver for receiving a data stream containing successive headers including data of a first type, with each header followed by a plurality of mixed data groups including digital data and data of a second type, said receiver comprising:
-
first means for detecting data of the second type from successive mixed data groups contained in a received data stream; second means for detecting data of the first type from successive headers contained in the received data stream; means responsive to the detected data of the first type and the detected data of the second type for recovering the digital data from the received data stream, the digital data including digital data representative of at least one of games and software; and means for reproducing a program from the recovered digital data. - View Dependent Claims (12, 13, 14, 15)
