Mitsubishi introduces ghost cancellation pre-processor IC for consumer products; fully compliant to Philips' Ghost Cancellation Reference (GCR) signal standard.SUNNYVALE, Calif.--(BUSINESS WIRE)--Sept. 5, 1995--A cost-effective pre-processor for ghost cancellation applications in televisions, set-top boxes and VCRs, was introduced by the Electronic Device Group of Mitsubishi Electronics America, Inc. The new ghost cancellation pre-processor, together with an adaptive filter chip (OR43100) from Oren Semiconductor and a standard 8- or 9-bit video A-D A-D Advance-Decline, or measurement of the number of issues trading above their previous closing prices less the number trading below their previous closing prices over a particular period. converter, provides the first fully compliant chip-set for the FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite. The FCC was created under the U.S. GCR (1) (Group Code Recording) An earlier encoding method used on magnetic tapes and Apple II and Mac 400K and 800K floppy disks.

Both the committee and the standard are called "NTSC. and PAL ghost cancellation standards. "Television signal deflections from buildings, mountains and other objects often cause images (or ghosts) as well as color reductions, loss of detail or contrast and smeared pictures on the viewer's TV screen," said David Thom, Mitsubishi Electronics product manager for Application Specific Standard Products. "Ghost cancellation technology makes it possible for these TV `ghosts' to be canceled dynamically if the broadcasting station transmits a Ghost Cancellation Reference (GCR) signal and a TV receiver has a ghost canceler." According to Thom, nearly 50 percent of all U.S. television broadcasting stations now transmit GCR signals. Mitsubishi's new M52661SP ghost cancellation mixed-signal interface IC cost-effectively provides de-ghosted analog signals to a television display. The device contains a 4 fsc burst-lock clock generating circuit, a synchronous separating circuit, a clamping circuit for digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). , an analog video switch and a 10-bit D-A converter. It also features a time-base error-detector circuit to detect channel change or VCR VCR: see videocassette recorder.

The M52661SP is offered in a 52-pin shrink DIP package. Commercial samples of the new ghost cancellation chip will be available in October. In volume quantities of 10,000 the device is priced at $12. Mitsubishi is working with Oren to provide application boards in October. Oren Semiconductor Ltd. designs, manufactures and markets ghost canceler ICs and adaptive equalizer ICs for the worldwide consumer television market, leveraging a strong technology foundation in patented digital filter and digital signal processing (DSP) technology. The company's ghost canceler products are compatible with all current and emerging ghost canceler reference signal standards worldwide.
