C-Cube?s chips are endorsed by Avid, NDS, General Instrument and C-Cube subsidiary DiviCom.............. broadcastingcable.com Technology Briefs Date Posted: 9/10/1999 C-Cube slices and dices HDTV C-Cube has developed an improved high-definition chip for video production and broadcast, it was announced last week. The new chip, dubbed DVx-HD, supports all ATSC high-definition and standard-definition compression formats and is based on C-Cube?s HD image processing technique, HDScan. Most encoding/decoding, or codec, chips handle video processing by ?tiling? the image--that is, dividing the bit rate into six equal tiles. Existing codec chips divide the 19.4 Mb/s HD signal into six individual tiles, each about 3.2 Mb/s, says C-Cube Marketing Manager Bob Saffari. The tiling technique can lead to artifacts and less-efficient compression, he says. C-Cube?s HDScan processing divides the image into nine ?slices? that ?talk? to each other and determine the bit allocation based on the amount of data present in each slice, says Saffari. This creates more ?uniform, crisp, clean, artifact-free images.? C-Cube plans to make the new chip available to manufacturers in the third quarter of 1999. C-Cube?s chips are endorsed by Avid, NDS, General Instrument and C-Cube subsidiary DiviCom. DiviCom creates new SD encoder While C-Cube is tackling HDTV, subsidiary DiviCom has developed a new standard-definition encoder, the MediaView MV45. The MV45 uses three C-Cube Dvxpert compression chips for a new noise-filtering technique called ClearMotion. ClearMotion was developed to handle the noisy analog sources that the majority of cable networks and satellite providers still use to generate compressed digital signals, says Eric Norton, director of DiviCom?s encoder product line. ?ClearMotion is motion-compensation filtering during the encoder process that differentiates noise from motion,? Norton explains. He expects the new technique to greatly improve encoding efficiency. ?We think for a lot of customers, this will give them an extra channel per transponder. ? There are a lot of noisy sources that take up a lot of bits.?

Did NBC buy the Divicom encoders????????????????????? www2.digitalbroadcasting.com{8FCA3F55-62DC-11D3-9A60-00A0C9C83AFB}&Bucket=Industry+News NBC Flagship Station Purchases Thomcast Transmitter 9/8/99 WNBC, NBC?s New York TV station, has picked Thomcast to supply its digital transmitter, to be installed in the World Trade Center. The Thomcast Ultimate Model Solid State transmitter is a UHF, 8-VSB, 15kW digital transmitter recently introduced on the market. Shipment is scheduled for December with an early 2000 on-air date. The transmitter also will have improvements designed to tackle VSB reception problems. The unit will be the first water-cooled solid-state 15kW 8-VSB digital transmitter in the US equipped with Thomcast?s Digital Adaptive Pre-Correction ?DAP? capability, which is designed to provide optimum signal-to-noise ratio performance. NBC also is using Comark (which merged with Comwave earlier this year to form Thomcast) transmitters at digital broadcast facilities in Los Angeles, Philadelphia, and Washington, DC.
