Abstract

A portable audio/video playback apparatus of the present invention comprises an apparatus main body 1 and a broadcast receiver unit 4 removably attached to the apparatus main body. The apparatus main body 1 includes interfaces 32, 33 for connecting thereto the broadcast receiver unit; an audio processing circuit 22 connected to one interface 32 for processing and feeding an external audio signal to a speaker 24; and a video processing circuit 27 connected to the other interface 33 for processing and feeding an external video signal to a display 13. The broadcast receiver unit 4 includes interfaces 55, 56 connected to the foregoing interfaces 32, 33 and decoders 47, 48 for feeding an audio signal and a video signal included in a received television broadcast signal to the interfaces 55, 56.

Claims

1. An audio/video playback apparatus comprising an apparatus main body with a speaker and a display capable of reproducing and outputting an audio signal and a video signal, and an audio/video receiver unit removably attached to the apparatus main body, the apparatus main body comprising:

interface means fur connecting thereto the audio/video receiver unit;

audio signal processing means connected to the interface means for applying a signal processing to an audio signal externally fed thereto to prepare a signal to be outputted to the speaker, and feeding the signal to the speaker; and

video signal processing means connected to the interface means for applying a signal processing to a video signal externally fed thereto to prepare a signal to be outputted to the display, and feeding the signal to the display,

the audio/video receiver unit comprising;

interface means connected to the interface means of the apparatus main body; and

signal feeding means for feeding an audio signal and a video signal included in a received signal to the interface means.

2. The audio/video playback apparatus according to claim 1, wherein the apparatus main body comprises power source means for serving as a power source of the speaker, the display, the audio signal processing means and the video signal processing means, while the audio/video receiver unit comprises power source means for serving as a power source of the signal feeding means.

3. An audio/video receiver unit removably attached to a device with a speaker and a display capable of reproducing and outputting an audio signal and a video signal, comprising:

first interface means connected to second interface means of the device; and

signal feeding means for feeding an audio signal and a video signal included in a received signal to the first interface means.

4. An audio/video playback method operated in an audio/video playback apparatus comprising an apparatus main body with a speaker and a display capable of reproducing and outputting an audio signal and a video signal, and a audio/video receiver unit removably attached to the apparatus main body,

wherein the method comprises

connecting the audio/video receiver unit to the apparatus main body,

feeding an audio signal and a video signal included in a signal received by the audio/video receiver unit to the apparatus main body,

processing the audio signal in the apparatus main body to prepare a first signal to be outputted to the speaker and feeding the first signal to the speaker,

processing the video signal in the apparatus main body to prepare a second signal to be outputted to the display and feeding the second signal to the display, and

reproducing the first signal and outputting the second signal.
