Triveni Digital and Dotcast Announce ATSC Data Broadcasting Integration
Triveni Digital Shows Industry-First End-To-End Demonstration of Carriage of Local Off-Air DTV Streams Over QAM to Cable-Ready DTV Receiver at Cable-Tec Expo 2002
San Antonio, TX (Cable-Tec Expo 2002, booth #207), June 5, 2002
Triveni Digital, a leading provider of professional broadcast products for data enhanced digital television, is demonstrating an industry-first end-to-end solution for carriage of terrestrial DTV broadcast signals over digital cable to cable-ready DTV receivers, at the SCTE Cable-Tec Expo 2002 (booth #207). Triveni is showing its StreamBridge solution for grooming the off-air ATSC PSIP data at the local digital cable head-end to ensure that the off-air signal carried via the cable system is compliant with the NCTA-CEA PSIP Agreement. The demonstration includes a cable-ready DTV receiver from LG Electronics that incorporates a QAM tuner and supports tuning and navigation of the signal using PSIP. Triveni Digital's StreamBridge is also being shown in various partners' booths including BigBand Networks (#1130), Motorola (#2138 and #4140) and Terayon (#351). The StreamBridge product is also capable of implementing different private carriage agreements between cable operators and networks/stations.
Triveni Digital's Cable-Tec Expo demonstration shows their new StreamBridge product placed at the cable head-end alongside a muliplexer. While the multiplexer performs grooming of the audio/video streams, the StreamBridge system processes the associated PSIP data in the stream - filtering, merging, and translating two or more PSIP data streams into a single PSIP stream. This PSIP stream is then transferred to the multiplexer where it is aggregated with the audio/video streams to feed a single QAM signal for delivery to subscriber-provided cable-ready digital TV receivers.
"This is a significant milestone in implementing the NCTA-CEA PSIP Agreement in an end-to-end manner," said Nandhu Nandhakumar, Vice President of Engineering and CTO of Triveni Digital. "We have been working with industry leaders such as Terayon, Motorola, CableLabs, BigBand, and major MSOs to accelerate cable-carriage of terrestrial DTV signals and ensure interoperability with cable-ready DTV receivers. We have demonstrated the high value of PSIP to subscribers and cable operators, and the ease of including PSIP in digital cable plants using our products that integrate seamlessly into existing head-end infrastructures with minimal impact on capital and operational costs."
Triveni Digital's StreamBridge automates and simplifies compliance with terrestrial-to-cable carriage agreements including the NCTA-CEA PSIP Agreement and other private carriage agreements for carrying ATSC DTV signals over local digital cable infrastructure. StreamBridge grooms data and metadata from terrestrial DTV streams, customizes them for the digital cable systems, optimizes streams to decrease bandwidth used by PSIP, dynamically updates Electronic Program Guide (EPG) data from terrestrial PSIP, and supports multiple inputs and outputs simultaneously.
