the deck assembly 227 spin to ensure proper operation when a network break is detected by mixer 217 the mpu 221 sends a signal to audio video switching circuit 211 to switch to dvd video and audio source the audio and video signals from the dvd deck assembly 227 are transmitted through the dvd video board through an audio attenuator 225 which sets the audio at the same level as the original incoming signal at input 203 and with video being passed directly to the audio video switching circuit 211 to be passed therethrough to the display device as connected to the system of fig2 the mpu 221 also checks for the change in channel through a signal which is received from the tuner electronics 207 and passed to the mpu 221 to perform appropriate preprogrammed functions as described in greater detail hereinafter in order to provide power and control a power supervisor board 231 is connected to a source of 120 volt ac power power is provided by the system to various elements of the dvd player namely an electromechanical counter 237 a dvd power supply unit psu board and counter driver 235 and a tuner power module 233 connected to the mpu 221 optionally the power supervisor board 231 can be further modified for connection to an optional circuit 239 which can provide additional functionality to the system in one aspect the optional circuit 239 includes a video motion detector 245 which provides signals to the power supervisor board 231 which in combination with signals from the audio amplifier and threshold detector.
