A plasma display panel is a type of flat-panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches/81 cm diagonal) flat-panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions.
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).
Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling). [50] Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays. [51]
Signal reception is invariably done via a superheterodyne receiver: the first stage is a tuner which selects a television channel and frequency-shifts it to a fixed intermediate frequency (IF). The signal amplifier performs amplification to the IF stages from the microvolt range to fractions of a volt.

HDTV antenna amplifiers counteract poor picture and sound on local TV broadcasts caused by a degraded cable signal, which may occur when you use an extra-long run of cable or a line that runs ...
The ATSC signal is more susceptible to changes in radio propagation conditions than DVB-T and ISDB-T. It also lacks true hierarchical modulation , which would allow the SDTV part of an HDTV signal (or the audio portion of a television program) to be received uninterrupted even in fringe areas where signal strength is low.
