1. A service and entertainment system for supplying frequency-multiplexed signals to a plurality of passenger seats, comprising:
- a head end apparatus comprising means for reproducing video signals, means for reproducing audio signals, means for storing television game software signals, encoder means for digitally encoding said audio signals and said television game software signals, means for modulating said video signals and said encoded audio signals and encoded television game software signals in channels of different frequency bands, respectively, and means for multiplexing said modulated video signals, modulated, encoded, audio signals, and modulated, encoded, television game software signals, respectively;
cable means for transmitting said multiplexed, modulated video signals, encoded audio signals, and encoded television game software signals; and
a plurality of terminal units each positioned at a different one of the passenger seats away from the head end apparatus, each said terminal unit including a means for selecting at least one of said multiplexed, modulated video signals, encoded audio signals, and encoded television game software signals, a tuner coupled to the selecting means for receiving and demodulating said selected multiplexed, modulated video signals, encoded audio signals, and encoded television game software signals, a decoder means for decoding the selected demodulated encoded audio signals and the selected demodulated television game software signals, a display means for displaying the selected demodulated video signals, an audio output terminal for receiving the selected decoded demodulated audio signals, and a means for storing and processing the selected, decoded, demodulated television game software signals.

Abstract
A service and entertainment system for transmitting video signals, audio signals and television game software signals from a central transmitting apparatus to each of a plurality of terminal units mounted at respective passenger seats in a passenger vehicle such as aircraft or the like, or at respective seats in a stadium, a theater, or the like. The video signals, audio signals and television game software signals are frequency-multiplexed and then transmitted to the terminal units, so that desired ones of the frequency-multiplexed signals can be selected at each terminal unit.
