Abstract

A digital television translator includes a digital television receiver for receiving a first digital television signal at a first frequency and generating a digital transport stream from the first digital television signal. The digital transport stream can include original Program and System Information (PSIP) data having RX channel data that is indicative of the first frequency, the first major channel number, and/or the first minor channel number. The digital television translator also includes a PSIP update module for updating the original PSIP data in the digital transport stream by replacing the RX channel data with TX channel data. The TX data is indicative of a second frequency, a second major channel number, and/or a second minor channel number. The digital television translator further includes a digital television modulator for converting the digital transport stream having the updated PSIP data into a second digital television signal at the second frequency, where the second frequency can be the same or different from the first frequency.

Claims

1. A system for translating a first digital transport stream containing one or more digital television programs carried in the first digital transport stream, comprising:

a program information update unit, the program information update unit supplementing one or more attributes for a virtual channel of a digital television program carried in the first digital transport stream; and

a multiplexor, the multiplexor combining the one or more attributes supplemented by the program information update unit and the first digital television program carried on the first digital transport stream to form a second digital transport stream.
