Transition to all MPEG-4 will optimize bandwidth utilization, readying the network for delivery of more high definition services
HORSHAM, Pa. – Motorola Mobility Inc. (NYSE: MMI) announced that Home Box Office (HBO) Latin America will upgrade its satellite network using MPEG-4 video encoding and DVB-S2 8PSK advanced modulation to launch all MPEG-4 programming. The solution compresses, encrypts, modulates, and receives the high definition (HD) signals within a single integrated transmission system to allow HBO Latin America to expand its HD offerings to subscribers. It also features many distribution system enhancements developed collaboratively between HBO Latin America and Motorola.
HBO Latin America will utilize Motorola’s SE-5100 encoder to process HD video content and convert it to MPEG-4 format for distribution via satellite to affiliates. At the affiliates’ downlink sites, the content will be received and processed real-time with Motorola's new DSR-4460 digital satellite receivers and DSR-6300 multi-channel integrated receiver/transcoders (IRDs) as part of the consolidated network-wide upgrade to MPEG-4 and, eventually, all-HD service distribution.
“Motorola’s advanced digital distribution solution leverages bandwidth efficient compression and modulation techniques to address the unique needs and challenging demands of HBO Latin America’s customer base,” said Jorge Duron, vice president and general manager, Latin America, Motorola Mobility. “It is the most advanced digital delivery system ever deployed in the region, yet remains very economical due to the advanced technologies that HBO Latin America developed in close cooperation with Motorola and have applied to their network.”
“Demand for high definition programing continues to grow in Latin America and Motorola’s commitment to the advancement of digital distribution will enable us to not only address our immediate network needs, but allow us to sustain our HD growth momentum long-term,” said Emilio Otermin, vice president of operations and engineering, HBO Latin America. “Working closely with Motorola, we designed an advanced digital distribution system to meet our unique needs and those of our affiliates.”
HBO Latin America will use Motorola’s uplink control system to execute a well-designed technology transition strategy. The new multi-format IRDs can be signaled to seamlessly transition from MPEG-2/QPSK to MPEG-4/8PSK services. The DSR-6300 IRD features a three-service MPEG-4 HD input that efficiently delivers content to the home in QAM-friendly transport bitrates, significantly increasing the number of services that can be delivered over a standard cable 256-QAM feed. The DSR-6300 also utilizes AFD (Active Format Descriptor) to translate input HD services to an appropriate standard definition (SD) service with proper aspect ratio and resolution. The DSR-4460 includes an MPEG-4 HD or SD input and a composite video SD output that also utilizes AFD. Both models of satellite receivers derive SD channels from the HD source, allowing programmers to free up additional bandwidth by transmitting the HD signal.
