The GuideBuilder™ system provides mission critical operational capabilities for both content providers and network operators by generating accurate Program and System Information Protocol (PSIP) data. PSIP is mandated by the FCC and forms the foundation for ATSC digital television transport streams as well as being important for digital cable carriage of Over the Air (OTA) broadcasts. Errors in PSIP data can cause serious problems including DTV tuners not finding your channel, closed captions not appearing, or programs not being listed in electronic program guides (EPGs). GuideBuilder's intuitive interface for managing program event information and flexible architecture ensure smooth operational integration. GuideBuilder can import program data from a wide variety of traffic systems, automation systems and commercial listing services. Local control is provided, by allowing program information or customized data to be manually entered into the system. Competitive advantage is maintained, allowing the retention of EPG branding and channel identity by the grouping of specific offerings under existing channel number, regardless of the frequency assigned to the digital broadcast. GuideBuilder's versatility and field proven capabilities have made it the system of choice for PSIP generation and management. Depending on operational needs, GuideBuilder provides the choice of three levels of functionality - Lite, Basic and Pro - all ensuring compliance with ATSC guidelines and FCC mandates.
