摘要： An apparatus automatically corrects for DC offset in a multi-level packet-switched receiver. A reference carrier frequency is used during the receiver's idle mode to establish a DC offset exiting a discriminator (302). The DC offset is amplified by a video amplifier (315) and fed into an error amplifier (320) which generates the negative of the DC offset. The DC offset and the negative of the DC offset are input into a summing network (330) resulting in a zero DC offset exiting the video amplifier (315).
摘要翻译：一种装置在多级分组交换接收机中自动校正DC偏移。在接收机的空闲模式期间使用参考载波频率来建立离开鉴别器（302）的DC偏移。 DC偏移由视频放大器（315）放大并馈送到产生DC偏移的负的误差放大器（320）。 DC偏移和DC偏移的负值被输入到求和网络（330）中，导致离开视频放大器（315）的零DC偏移。

摘要： A method and apparatus for multiplexing a plurality of communication signals where the communication signals may operate using different protocols is provided. A communication node (102) that is a part of a communications system or network (100) is provided. The access point includes a transceiver (202, 204) for transmitting and receiving a first signal and a second signal wherein the first signal (410) is using a first protocol and the second signal (412) using a second protocol. The access point also includes a scheduler (208) for scheduling a transmit time for the first signal and for the second signal within a first frame (402, 404) and a receiving time for the first signal and for the second signal within a second frame (406, 408). A multiplexer (210) is also provided where the multiplexer combines the first signal and second signal in the first and second frames according to the scheduled transmit time and receive time.

摘要： A self-contained wireless camera and a wireless camera system having such a device and a base station. Video processing (e.g. video compression) circuitry of the camera device receives video signals from a camera and provides processed video signals. These are transmitted over a shared radio channel. A radio receiver 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. The base station device 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 can be selected according to the application that the user selects for operation.
