TV Azteca, the second largest broadcaster in Mexico, has deployed Harmonic’s IP-based video processing solutions to facilitate satellite distribution of its expanded HDTV service to hundreds of retransmission sites throughout Mexico and Central America. The new DVB-S2-based distribution system relies on Harmonic’s multifunction compression and stream processing solutions to reduce the cost of satellite uplink and transmission through more efficient use of the satellite bandwidth.

“Harmonic’s compression and stream processing solutions provide the bandwidth efficiency, video quality, reliability, and versatility required to meet our needs, while enabling us to expand our HD service,” said Ing. Román Gomez Mendez, department director, engineering and advanced technology development at TV Azteca. “The new distribution system allows us to securely transmit HD MPEG-4 AVC content over satellite and transcode to multiple formats for retransmission over terrestrial broadcast networks, while providing excellent video quality.”

TV Azteca is using Harmonic’s Electra 7000 HD AVC encoders and the ProStream 1000 stream processing platform with DiviTrackIP statistical multiplexing and DVB scrambling to deliver secure, high-quality services while optimizing bandwidth efficiency. Harmonic’s ProView 7000 integrated receiver/decoders (IRDs) and ACE any-to-many real-time transcoding technology are used by TV Azteca for content reception and format conversion.

Project integration and system installation were performed by Teletec de Mexico, SA de CV, a Harmonic reseller and systems integrator in Mexico.

“Cost-effective transmission of high-quality content is among the primary business challenges facing broadcasters today,” says Richard Phelps, VP of sales for Latin America at Harmonic Inc. “Harmonic’s complete offering for high-quality HD encoding, DVB-S2 distribution and dense transcoding enables operators such as TV Azteca to significantly reduce bandwidth usage costs associated with distribution to terrestrial transmitters and increase the range and quality of the services they provide.”
