Patent ID: 7688868

Claim:
A monitor, comprising: an information receiving part, comprising: a receiver for receiving a transmitted signal; a first unit for capturing a video signal from said received signal; a detecting unit for detecting a blanking period of said captured video signal, said blanking period being set to a length different from an original period; a second unit for capturing information on a multiplexing period of said captured video signal in which a compressed audio signal is multiplexed; a third unit for capturing said multiplexed compressed audio signal from said captured video signal on a basis of said captured information on said multiplexing period; and a correcting unit for correcting said detected blanking period on the basis of said captured information on said multiplexing period; data indicative of the duration of the multiplexing period is received during said blanking period of said captured video signal; and a controller for controlling said information receiving part; an RGB amplifier for amplifying video data output from said information receiving part; a monitoring device for receiving video data output from said RGB amplifier and for producing moving images according to said video data; a H/V sync generating unit for generating a horizontal synchronizing signal and a vertical synchronizing signal on the basis of synchronizing data output from said information receiving part; a buffer for buffering audio data received by said information receiving part and converting said audio data into continuous data; and left-channel and right-channel speakers for producing sound according to said continuous data.
