ANSI Approves 2 SCTE Standards

The American National Standards Institute has approved two SCTE standards, one covering digital video transmission and the other covering data transport.ANSI/SCTE 07 2013, "Digital Transmission Standard for Cable Television," describes the framing structure, channel coding and channel modulation for a digital multi-service TV distribution system that is specific to a cable channel. The system can be used transparently with the distribution from a satellite channel, as many cable systems are fed directly from satellite links.ANSI/SCTE 19 2013, "Methods for Isochronous Data Services Transport," defines transmission format for the carriage of isochronous data services compatible with digital multiplex bitstreams constructed in accordance with ISO/IEC 13818-1 (MPEG-2 Systems). Bit rates for the data services extend from 19.2 kbps to 9.0 Mbps.Both standards are available at http://www.scte.org/standards/Standards_Available.aspx.
