Self-Contained Wireless Camera Device, Wireless Camera System and Method
First Claim
1. An wireless device comprising:
- a camera generating video information contained in a signal transmitted over a wireless channel, wherein the wireless channel has a total bandwidth capability; and
a communications interface receiving an initial command to utilize a first bandwidth utilization on the wireless channel in accordance with a first set of parameters and receiving a subsequent command to utilize a second bandwidth utilization on the wireless channel in accordance with a second set of parameters, wherein the second bandwidth utilization is less than the first bandwidth utilization and wherein a total bandwidth utilization of all wireless devices communicating on the wireless channel is not greater than the total bandwidth capability of the wireless channel.

Abstract
A self-contained wireless camera (10) and a wireless camera system (25) having such a device and a base station (20). Video processing circuitry (200, 210) of the camera device receives video signals from a camera (130) and provides processed video signals. A radio receiver (101) receives processed 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 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.
