PSIP (Program System Information Protocol) is the standard file format that stations feed into the PSIP generator. The PSIP data is transmitted along with the digital television (DTV) signal which then shares important station and programming information. In turn, the ATSC tuner inside a digital television will display the information for consumers to view via an electronic program guide (EPG). MediaStar PSIP is customized to interact with the MediaStar Suite, enabling station personnel to plan, change and publish their base schedule in real-time. The MediaStar Suite of program management tools provides a one-step publishing process, which in addition to updating PSIP data also updates the station’s TitanTV data services and the national listings guide at TitanTV. com. MediaStar PSIP is able to be delivered in a variety of formats including the industry benchmark, PMCP (Programming Metadata Communication Protocol).
