Abstract

A wireless audio/video system with remote playback and control comprises a main system unit and a portable control and playback device. The main system unit comprises a wireless reception sub-system for receiving audio and video signals, an audio/video signal processing sub-system for processing signals received by said wireless reception sub-system, an audio/video output sub-systems for retransmitting said audio/video signals, one or more audio power amplifiers for amplifying said audio signals, and an input signal selection system for receiving control signals from a remote device. The portable control and playback device comprises a program material storage sub-system, a program material playback sub-system for playing material stored in said program material storage sub-system, a main system unit control sub-system, and a wireless transmission sub-system.

Claims

1. A wireless audio/video system with remote playback and control, comprising:

a main system unit, comprising;

a wireless reception sub-system for receiving audio and video signals,

an audio/video signal processing sub-system for processing signals received by said wireless reception sub-system,

audio/video output sub-systems for retransmitting said audio/video signals,

one or more audio power amplifiers for amplifying said audio signals, and

an input signal selection system for receiving control signals from a remote device, and

a portable control and playback device, comprising;

a program material storage sub-system,

a program material playback sub-system for playing material stored in said program material storage sub-system,

a main system unit control sub-system, and

a wireless transmission sub-system for transmitting signals from the main system control unit to said wireless reception sub-system of the main system unit.

2. The system of claim 1, wherein the portable control and playback device is configured as a satellite control and playback device and acts as a repeater for the wireless signal transmitted from another portable control and playback device which has been set as a master unit or to enable multiple users for one system, or to extend wireless transmission range so that a plurality of users can be included in a wireless audio video network.

3. The system of claim 2, wherein a said satellite portable control and playback device is configured to send request signals to the master portable control and playback device, and wherein the master device is configured to set the system to playback audio and video signals transmitted from said satellite portable control and playback device, thereby operating as a wireless conference system with audio and video capability.

4. The system of claim 1, wherein said portable control and playback device further comprises a video display system.

5. The system of claim 1, wherein said portable control and playback device further comprises an audio playback system.

6. The system of claim 1, wherein said portable control and playback device further comprises a wireless receiving sub-system for receiving wireless signals from other portable control and playback devices.
