Harmonic Provides End-To-End Solution at TV Centro América

Harmonic powers new HD and ISDB-T 1seq services for TV Globo affiliate TV Centro América

Harmonic announced that TV Centro América, a TV Globo affiliate based in Cuiabá, Brazil, is using Harmonic to power its new free-to-air multiscreen service. The company recently deployed Harmonic’s end-to-end contribution, satellite distribution and reception solution. SDB Comercial, Harmonic's local distribution partner, supplied the system in addition to providing professional services and support.

Harmonic enables the channel to deliver HDTV content to viewers on TV screens, as well as mobile devices utilizing the ISDB-T 1seq mobile terrestrial digital broadcasting service.

TV Centro América wanted to upgrade its legacy SD system to deliver free-to-air HD content on TVs and mobile devices. The station needed a powerful infrastructure solution capable of delivering superior-quality video at the lowest possible bit rates.

For distribution, Harmonic's ProView 7100 IRDs are used for descrambling and decoding. The IRDs also perform HD down-conversion and aspect ratio adaptation to generate PAL-M broadcast-quality baseband analog video and audio, keeping TV Centro América's analog transmission on-air until the government mandated switch-off scheduled for 2018. The ProView IRDs are controlled by Harmonic's DMS video distribution management system.

For delivery, TV Centro América is using Harmonic's Electra 8200 universal HD MPEG-2 and AVC encoders to provide high-quality, low-bandwidth MPEG-4 AVC encoding of video content for its new multiscreen service. Additionally, Harmonic's ProStream 1000 stream processing platforms support scrambling of DVB simulcrypt applications, working in sync with conditional access systems from Irdeto and Nagravision.

TV Centro América is also using the Harmonic Ellipse 3000 contribution encoder and ProView IRDs at its Cuiabá facility for contribution purposes. The facility delivers live productions via a terrestrial IP network to stations in the Mato Grosso Television Network, covering more than 200 cities in the region. The Ellipse and ProView platforms are also installed within TV Centro América's DSNG trucks. Together, the contribution encoders and IRDs provide TV Centro América with a high-density, scalable and bandwidth-efficient contribution solution that maintains superior video quality during live broadcasts.

Harmonic is in NAB 2015 booth SU1210.
