Abstract: Existing infrastructures such as DS1 or E1 are used at currently accepted rates to carry a third more information by using a hybrid encoding technique wherein a 4B3T encoding is done for the payload bits, while a 1B1T encoding technique is used for framing information. In this way, for example, a DS1 can be used at 1.54 Mbit per second to carry 2.058 Mbits of binary payload, while respecting the 8 kilobits of framing expected by DS1 hardware.  Similarly, for example, an E1 infrastructure can be used at the accepted 2.048 Mbit per second rate to carry 2.560 Mbits of binary payload plus 128 kilobits of binary framing/CRC without having to change the accepted E1 framing techniques.

Abstract: A digital television system receives transmitted television information in the form of a stream digital packets representing video and audio information in compressed form. A packet transport unit routes the digital packets to respective digital video and audio signal processing sections according to header information contained in the packets. The digital processing sections decode and decompress the respective packets to form sequences of digital words which are subsequently converted to analog form. Apparatus for providing audible messages, such as operating instructions and status information, in tone or voice form includes a memory for storing digital representations of the audible messages in the same compressed form which the transmitted audio packets have, and a controller for selectively directing the digital representations to the packet transport unit when it is desired to provide the audible messages. The digital representations of the audible messages are automatically routed by the transport unit to the digital audio signal processing section which will decode and decompress the digital representation of the audible messages in the same manner as it does the transmitted audio packets. As a result, analog versions of the audible messages will be produced.
