The Common Interface allows TV manufacturers to support many different pay TV stations, by allowing to plug in exchangeable conditional-access modules (CAM) for various encryption schemes. The Common Interface is the connection between the TV tuner (TV or set-top box) and the module that decrypts the TV signal (CAM). This module, in turn, then ...
Perceptual Evaluation of Audio Quality (PEAQ) is a standardized algorithm for objectively measuring perceived audio quality, developed in 1994–1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union's Radiocommunication Sector . It was originally released as ITU-R Recommendation BS.1387 in 1998 and ...
TV viewers can be affected as well. If a home theater receiver with external speakers is used, then the display lag causes the audio to be heard earlier than the picture is seen. "Early" audio is more jarring than "late" audio. Many home-theater receivers have a manual audio-delay adjustment which can be set to compensate for display latency.
As the cases on many computers are not perfect shields, some of this radio-frequency energy can leak out and cause interference to radio (and sometimes TV) reception. Switched-mode power supplies or packs can be a source of interference. [quantify] These are used in consumer electronic products such as phone charges and in some lighting systems.
The audio encoding is the last to suffer a loss due to the lower bandwidth requirements. [citation needed] Standards that support digital SDTV broadcast include DVB, ATSC, and ISDB. [5] The last two were originally developed for HDTV, but are also used for their ability to deliver multiple SD video and audio streams via multiplexing.
The elements of a simple broadcast television system are: . An image source. This is the electrical signal that represents a visual image, and may be derived from a professional video camera in the case of live television, a video tape recorder for playback of recorded images, or telecine with a flying spot scanner for the transfer of motion pictures to video).

In contrast, Japanese ISDB HDTV broadcasts use MPEG's Advanced Audio Coding (AAC) as the audio codec, which also allows 5.1 audio output. DVB (see below) allows both. MPEG-2 audio was a contender for the ATSC standard during the DTV "Grand Alliance" shootout, but lost out to Dolby AC-3. The Grand Alliance issued a statement finding the MPEG-2 ...
