YCrCb - Almost identical to YPrPb. If you connect a YCrCb unit to a YPrPb unit you might have to adjust the color slightly. YCrCb is an older standard uncommon for consumer connections.

DLP - (digital light processor). A technology for video projection, also call DMD (Digital Micro-mirror Device). It is a large chip with about a million tiny mirrors on its surface. The chip can tilt each mirror to vary the amount of light reflected off of it.

DTS - Digital Theatre Sound System. A Dolby proprietary discrete 5.1 channel surround system similar to, but not the same as Dolby Digital AC-3, the DTV standard. DTS is used in cinema presentations and in DVD's.

Interoperability - This refers to the ability of a system or a product to work with other systems or products without special effort on the part of the customer. For example, interoperability would be required for a digital television set to be plugged into a VCR that is plugged into cable with all the components working together.

Bandwidth - The range of frequencies used to transmit the television signal, including picture and sound. Analog television signals have been allocated at 6 Megahertz for each over-the-air channel. Digital channels are allocated the same 6 Megahertz by Industry Canada. However, by the use of digital compression, a combination of up to 5 SDTV programs and/or one HDTV program can be carried in this 6 MHz digital channel.

Must-carry - This refers to the legal obligation of cable companies to carry analog or digital signals of over-the-air local broadcasters.

Compression - A method of reducing the number of bits required to store or transmit programs by the removal of redundant and/or non-critical information in the digital picture and sound. The DTV broadcasting standard for Canada, uses the MPEG-2 video and the AC-3 audio compression coding. Compression allows the delivery of more programs in a single channel.

ATSC - "Advanced Television Systems Committee." Formed to establish technical standards for U.S. advanced television systems. ATSC is now used as the catch-all nomenclature for DTV broadcast standards.
