A DigitalTransmission process used to transmit a video signal. When the vast amount of information in a video transmission is compressed into a fraction of its former Bandwidth by a codec, the resulting compressed video can be transmitted more economically and through existing phone lines. While compressed video requires less bandwidth, signal quality may be reduced. As a result, picture quality is generally not as good as full-motion video. Quick motions often appear somewhat blurred. This quality issue is becoming less of a concern as more and more playback systems for compressed video run at 30 Frames per second.
