The Program and System Information Protocol (PSIP) is a collection of tables designed to operate within every transport stream for terrestrial broadcast of digital television. It describes the information at the system and event levels for all virtual channels carried in a particular transport stream and to allow program schedule information to be displayed on ATSC-compatible digital TV receivers. PSIP is not only the foundation for maintaining the station's digital TV identity, but also the delivery of a rich variety of television-related data services, including the electronic program guide data, caption service data, content advisories, and support of multiple languages. The primary purpose of PSIP is to facilitate acquisition and navigation among the analog and digital services available to a particular receiver or set-top-box, but it also serves as a support platform for applications such as data broadcasting. Delivering PSIP data is essential for digital terrestrial broadcasters in North America and South Korea.

DTVi's PSIP Pro software is an accurate, easy to use, and feature rich PSIP (Program & System Information Protocol) generation and management software system. It contains advanced capabilities and a user-friendly graphic interface at a cost-effective, entry level price.
