Harmonic displayed an IP-based ATSC headend solution incorporating Triveni Digital's GuideBuilder program and system information protocol (PSIP) generation system at NAB2007.
GuideBuilder is integrated with Harmonic's ATSC headend, which includes a DiviCom MV 500 HD MPEG-2 encoder, Electra 5000 SD MPEG-2 encoder and ProStream 1000 stream processing platform with DiviTrackIP statistical multiplexing. The solution provides broadcasters with an IP-based infrastructure that enhances their service offerings by supporting multiple HD and SD channels in the allocated spectrum.
The system generates accurate PSIP data, which forms the foundation for ATSC digital television transport streams, and supports digital cable carriage of over-the-air broadcasts. It also features an intuitive interface for managing program event information and helps to ensure compliance with ATSC guidelines and FCC mandates.
