Motorola announced the DSR-6300 — the industry’s first commercial receiver/decoder (IRD) to deliver three-channel MPEG-4 to MPEG-2 HD transcoding — enabling cable operators to increase HD throughput by up to 50 percent while offering satellite operators greater flexibility in packaging HD services to their affiliates.
The DSR-6300 features Motorola’s closed-loop statistical multiplexing, which dynamically allocates the optimal bandwidth to each program using Motorola patented video complexity analysis. This process provides appropriate and timely bit rate adjustments to services as video becomes more or less difficult to encode. As a result, up to three HD services can be efficiently delivered to the home in QAM-friendly transport bit rates, significantly increasing the number of services that can be delivered over a standard cable 256-QAM feed.
The DSR-6300 simultaneously uses the in-band active format descriptor (AFD) to translate input HD services to an appropriate standard definition (SD) service with proper aspect ratio and resolution. This will allow programmers to migrate to HD-only distribution strategies, further freeing up valuable satellite bandwidth for delivering even more HD services.
