Self-contained wireless camera device, wireless camera system and method
First Claim
1. A self-contained wireless camera device comprising:
- a camera;
video compression circuitry, coupled to the camera that receives video signals from the camera and that provides compressed first video signals;
a radio transmitter coupled to the video compression circuitry for transmission of the compressed first video signals; and
a radio receiver for receipt of command signals, wherein the video compression circuitry is responsive to receipt of a control command by the radio receiver to modify operation of the video compression circuitry.

Abstract
A self-contained wireless camera (10) and a wireless camera system (25) having such a device and a base station (20). Video processing (e.g. video compression) circuitry (200, 210) of the camera device receives video signals from a camera (130) and provides processed video signals. These are transmitted over a shared radio channel. A radio receiver (101) receives processed (e.g. compressed) video signals from the base station or another camera device. Images from the camera or the base station are displayed in a selected manner on a display or monitor (140). The base station device (20) receives processed (e.g. compressed) video signals, stores them and retransmits them. A command signal is received by the radio receiver to modify operation in such a manner as to control bandwidth usage. Wireless camera devices can adjust their operation to accommodate other wireless camera devices. Different transport protocol modules 230 and 240 can be selected according to the application that the user selects for operation.
