Infinifocus™ CRTs: Infinifocus CRTs are picture tubes with color filter lenses and Intellifocus™ digital auto convergence that display a bright, automatically aligned video image.

Many audio/video components come packaged with cables.
Integrated HDTV: Integrated HDTV means there is a digital turner built into the display, so the display can receive over-the-air DTV signals without a separate receiver (set-top box).
Interconnect: An interconnect is another term for the cables used to connect video and audio components. Cables come in a variety of lengths. Each cable has some form of termination at both ends. The termination, or connector, is what actually connects to the inputs and outputs on a component.

The common terminations for video cables are RCA (composite video), S-video, and F-type (used with coaxial cable for cable TV, antennas, etc.). The most common terminations or connectors for audio cables are RCA (most widely used), XLR, and Toslink (fiber-optic).

Many audio/video components come packaged with cables.
Interlaced: Interlacing is a method of combining two fields of information to create one complete image, or frame. The first field contains the odd lines of information, and the second field contains the even lines of information. The first field, with the odd-numbered lines, is drawn first, and then the second field, with the even lines, is drawn second to complete the frame.

Interlaced video is the standard for analog NTSC video distribution. Digital ATSC video can be either interlaced video or progressive scan video.

Interlaced video is different from non-interlaced (progressive scan) video, which paints each line of the frame sequentially. The interlaced video method saves bandwidth, but it can result in a shakier, less detailed image.
IR (Infrared): Infrared (IR) light beams are invisible to the human eye, but are used in many remote control devices to transmit information and commands to components. IR works like other light beams, traveling in a straight line. In order for an infrared command to work, there must be a clear, unobstructed path between the IR emitter that is sending the signal and the component that is receiving the signal.
IR Emitter: An IR emitter generates infrared (IR) light beams that transmit information and commands from one device to another.

The most common use of an IR emitter is in a remote control. The remote sends signals (invisible to the human eye) to a component, and the IR receiver in the component picks them up. When IR signals reach a receiving component they are deciphered, and the component performs the function you selected on the remote control.
