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.

Abstract: Techniques for communicating between a data user and a destination through a mesh network. The mesh network includes a communication node having a downstream component logically connected over a downlink to provide communications for a data user and a plurality of upstream components. The plurality of upstream components includes a first upstream component that is logically connected to a first data destination over a first uplink. The communication node also has a controlling component that selects the first upstream component based on a first comparative link quality of the first uplink, where the first downstream component is electrically coupled to the first upstream component. The controlling component determines the first comparative link quality from a plurality of link quality metrics, where a corresponding weight is associated with each link quality metric.

Abstract: Apparatuses and methods for multiplexing of DS1 traffic across wired and wireless Ethernet devices. A transmitter sends data packets to a receiver through an Ethernet system. The transmitter includes a modeling module that constructs a modeled jitter buffer corresponding to a receiver jitter buffer located at the receiver. The transmitter also includes a packetizing buffer that collects data to form data packets, that inserts buffer pointers into the data packets, and that sends the data packets through the Ethernet system. A buffer pointer is determined from the modeled jitter buffer. The receiver includes an Ethernet interface module that obtains the data packets from the Ethernet system, a jitter buffer, and a depacketizer that reads a buffer pointer in the data packet and that places the data packet into a position within the receiver jitter buffer in accordance with the buffer pointer.

Abstract: Data elements, preferably representative of video data, are logically divided into blocks. In a bit-wise fashion, each block is inspected to determine whether the data elements for that block may be represented in a highly compact format. If a given block may not be represented in this manner, it is sub-divided into blocks having smaller dimensions. This process of identifying suitable blocks and sub-dividing is recursively repeated until minimum block dimensions are reached. The same result may be achieved through the use of a plurality of ascending tables that are constructed by repetitively forming tables of reduced data elements. The plurality of ascending tables is traversed and, based on the reduced data elements, blocks of data are identified that are susceptible to the highly compact format. Wavelet transforms are preferably used to provide video data to be compressed.

Abstract: The quality of a channel for each of a plurality of receive antennas is determined in part by examining data collected during reception of test data. Substantially simultaneously, payload data is also used to evaluate channel quality for at least one antenna. A quality metric calculated for any given antenna is the result of measurements made upon the test and payload data. Parameters used to calculate the quality metric are preferably divided into two sets of non-identical parameters, those based on the test data and those based on the payload data. These parameters preferably include jitter, received signal strength, CRC errors and synchronization errors. By continuously updating quality metrics based on both test and payload data, more reliable assessments can be made of the various antennas being used. As a result, antenna selection is rendered commensurately more reliable thereby improving received signal quality.
