System and method for dynamically transmitting program system information from television network to stations using information embedded in an HDTV signal

摘要

A system for dynamically transmitting recent program system information from a television network to an affiliate station using information embedded in an HDTV signal includes a program data server configured to provide current program system information protocol (PSIP) data, a network video programming source configured to provide network video programming, a data inserter configured to insert the PSIP data into vertical ancillary (VANC) space of a high definition television (HDTV) signal to develop a combined network video programming and PSIP data signal, and a transmission facility configured to transmit the combined network video programming and PSIP data signal.
