H.264/AVC - Advanced Video Coding

H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors.

The standard offers up to twice the compression of MPEG-4 ASP (Advanced Simple Profile). In addition to improvements in perceptual quality, the H.264 standard can provide DVD-quality video at under 1 Mbps.

QPSK - Quadrature Phase Shift Keying

Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to carry twice as much information as ordinary PSK using the same bandwidth. QPSK is used for satellite transmission of MPEG2 video, cable modems, videoconferencing, cellular phone systems, and other forms of digital communication over an RF carrier.

QAM - Quadrature Amplitude Modulation

QAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications.

RF - Radio Frequency

Radio frequency (RF) is a rate of oscillation in the range of around 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

HDMI - High Definition Multimedia Interface

HDMI (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with digital versatile disc (DVD) players, digital television (DTV) players, set-top boxes, and other audiovisual devices.

TS - Transport Stream

Transport stream (TS) is specified in MPEG-2, and it is a standard format for transmission and storage of audio, video, and data, and is used in broadcast systems such as DVB and ATSC. Transport stream specifies a container format encapsulating packetized streams, with error correction and stream synchronization features for maintaining transmission integrity when the signal is degraded.

ASI - Asynchronous Serial Interface

Asynchronous Serial Interface, or ASI, is a streaming data format which often carries an MPEG Transport Stream (MPEG-TS).

STB - Set Top Box

A set-top box (STB) is an information appliance device that generally contains a TV-tuner input and displays output connects to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device.

CATV - Cable Television

CATV is a shorthand term for cable television service. Many providers offer cable Internet service together with television to their customers over the same CATV links.
