HORSHAM, USA: As higher bandwidth video services such as high definition (HD) 1080i, HD1080p60 and 3D TV proliferate, studios and programmers continue their shift to MPEG-4 based satellite video distribution. The benefit to content providers is the freeing up of costly satellite transponder space, making room for new HD channels.
The challenge for cable operators is their video infrastructure and home devices are almost exclusively designed to support legacy MPEG-2 formatted video services. To address this challenge, Motorola Mobility, Inc. (NYSE: MMI) is introducing the DSR-6400 family of integrated satellite receiver transcoders.
Offering support for single, dual, three and four channel configurations, The DSR-6400 family is an integrated design combining traditional IRD functions and transcoding functions into a single unit that fits within a sing;le RU.. Each channel of the DSR-6400 series can independently transcode the input MPEG-4 HD video service into simultaneous MPEG-2 standard definition (SD) and HD video outputs.
This flexibility in design provides operators the ability to support legacy MPEG-2 based video services simultaneously as they begin the bandwidth saving shift to MPEG-4 based video delivery services all in one DSR-6400 unit. In addition, the DSR-6403 and DSR6304 support a very-high quality closed-loop statmux capability, to maximize transmission bandwidth efficiency while ensuring subscribers enjoy the ultimate in picture quality and viewing experience.
With simple setup via the front panel, web browser, or from a satellite uplink control from the programmer, the DSR-6404 can be provisioned for CBR and VBR video bitrate encoding, allowing for very high quality video statmux in groups with up to four HD channels within a 256-QAM multiplex bitrate of 38.8Mbps. The DSR-6400 also utilizes AFD (Active Format Descriptor) to translate input HD services to an appropriate SD service with proper aspect ratio and resolution, ensuring that video is display-ready for screens of any size and format.
The DSR-6400 family of products also includes a variety of interfaces for several configuration options. Specifically, they include come equipped with radio frequency (RF), Gigabit Ethernet and Adapter Support Interface (ASI) inputs and outputs formats to enable seamless connections to existing headend equipment for easy installation and deployment. An additional Ethernet port also allows for web browser monitoring and control.
