In addition to DHEI, the other interfaces include: a High Speed Serial (HSS) interface compatible with General Instrument's DigiCipher-II and Broadcom's QAMLink digital broadcast equipment; a combination DVB Synchronous Parallel Interface (SPI) and Asynchronous Serial Interface (ASI) compatible with all equipment using this defacto European digital broadcast standard; and SMPTE 310M, the recently accepted ATSC standard for digital terrestrial broadcast of SDTV and HDTV transmissions.
The UNITY4600 IRD will fit most locations, but at existing cable headends that need a DHEI interface the DTV735 groomer works like hand and glove with the UNITY IRD's.
The centerpiece of the DVB headend will be the PowerVu(R) BitMizer(TM) multiplexer, a high performance MPEG-2 packet multiplexer that supports both DVB-ASI and DHEI formats.

The PowerVu BitMizer multiplexer is a high performance MPEG-2 packet multiplexer that supports both DVB-ASI and DHEI formats, supports statistical re-multiplexing of both standard definition and high definition signals, and is the only multiplexer capable of grooming sufficient output capacity to fully drive the Scientific-Atlanta(R) MQAM from a single device.
MediaPumpXL offers DVB-ASI, DVB-LVDS, RS-422 or DHEI interfaces that connect high-speed synchronous MPEG-2 multi-program interfaces to PCI bus-based servers.
The MDRs will allow Fox to deliver its digital multiplex easily to Scientific-Atlanta and other digital headends using SWIF, DHEI, or DVB-ASI interfaces.
Viewgraphics' MediaPumpXL is an add-in card with DVB-ASI, DVB-LVDS, RS-422 or DHEI interfaces that connects high-speed synchronous MPEG-2 multi-program interfaces to PCI bus-based servers.
With a proven track record for compatibility and reliability, and more than two years of continuous live operation and hundreds of channels currently on-air, Viewgraphics' technology sets the standard for DVB and DHEI compliant MPEG-2 server technology.
The announcement of DHEI and DVB-LVDS support extends MediaPump XL's power and flexibility and demonstrates Viewgraphics' ability to incorporate new standards in the digital broadcast arena.
