Scientific Atlanta Expands MPEG-4 AVC/MPEG-2 Digital Leadership

New Encoder and Decoder Platform Saves 40 Percent More Bandwidth

SAN JOSE, Calif./ATLANTA - Scientific Atlanta®, a Cisco company, today announced new releases of its MPEG-4 advanced video compression (AVC) encoders and a new set of digital integrated receiver/decoders (IRDs) that will help deliver the flexibility and high-quality video performance needed for today’s advanced digital TV services.

The next-generation encoders (models D9054TM and D9034TM) deliver up to 40 percent improvement in bandwidth savings compared with previously deployed MPEG-4 AVC encoders. These Scientific Atlanta AVC encoders are now available and support integrated picture-in-picture (PIP) and capped variable bit rate (VBR), using a powerful single-slice, dual-pass architecture. Among the four new IRDs is an MPEG-4 AVC HD decoder to provide expanded flexibility for operators through a modular architecture that supports a variety of input and output configurations. The new IRD (model D9887TM) supports new DVB-S2 modulation technology for up to 30 percent bandwidth improvement over satellite links.

“Across Europe, the launch and expansion of digital video services are continuing at a rapid pace,” said Dean Rockwell, vice president and general manager of Digital Media Networks. "Scientific Atlanta’s single-slice MPEG-4 AVC HD encoding architecture allows us to continue to improve the encoding efficiency over the long run, thereby allowing operators to deploy services at lower bit rates without compromising video quality.

“The MPEG-4 AVC encoding standard allows for significant improvements over time, so it is crucial that operators deploy encoders today that have the ability to capitalize of these improvements,” added Rockwell.
