Abstract:
A computer-implemented method is disclosed including: receiving a broadcast signal containing a set of multiplexed multimedia channels; storing said multiplexed multimedia channels in a temporary storage buffer on a mass storage device; determining a point in said temporary storage buffer to begin demultiplexing and decoding a first channel responsive to a user request to view a particular program on said first channel in its entirety, said point indicating the start of said program on said first channel; and demultiplexing and decoding said first channel of said set of multiplexed multimedia channels from said point within said temporary storage buffer.
Abstract:
A method is described comprising: transmitting a training signal from each antenna of a base station to each of a plurality of client devices utilizing tropospheric scatter, each of the client devices analyzing each training signal to generate channel characterization data, and transmitting the channel characterization data back to the base station utilizing tropospheric scatter; storing the channel characterization data for each of the plurality of client devices; receiving data to be transmitted to each of the client devices; and precoding the data using the channel characterization data associated with each respective client device to generate precoded data signals for each antenna of the base station; and transmitting the precoded data signals through each antenna of the base station to each respective client device.
Abstract:

Abstract:
A method of operation for wireless transmission of data to one or more destination devices across a network that includes a plurality of access points disposed about a building, each access point having a first transmission range of maximum bandwidth and a second transmission range of signal interference, the access points being arranged in a topology wherein each access point is spaced-apart from a nearest neighboring access point by a first distance less than the first transmission range. The data is transmitted by a first access point; then it is repeated by a series of additional access points that extends across the topology. Re-transmission of the data occurs in a manner wherein any pair of access points transmitting on the same channel is separated by a distance greater than the second transmission range. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
Abstract:
Systems and methods for recording a signal received by a home entertainment system that includes multiple consumer electronics devices interconnected to a central electronics device in a hub and spoke configuration. The configuration allows all signals in the home entertainment system to be accessible by the central electronics device. Accordingly, the central electronics device can process, route, or otherwise respond to any signal. By way of example, any signal can be routed to a recording system, where it can be recorded. The signal is coupled with information from an electronic programming guide that details specific programming. An automatic determination is made as to whether or not there exists enough free space on a recording medium to record a specific program. Upon recording the program on the recording medium, an index is updated on the recording medium from the electronic programming guide information and from the location of the program on the recording medium. By selecting the program from the index, the recorded program can be automatically located on the recording medium.
Abstract:
A method implemented on a multimedia storage apparatus comprises storing digital multimedia content, compressed using a first compression type, in an interim storage buffer, the first compression type being the type at which the digital multimedia content was transmitted by a multimedia content broadcaster; decompressing the multimedia content; recompressing the multimedia content using a second compression to create recompressed multimedia content; and storing the recompressed multimedia content in a long term storage buffer.

Abstract:
An apparatus and method for combining digital information with at video stream and for using the digital information to modify or augment video frames in the video stream is disclosed. The apparatus for decoding a video stream comprises a video receiver configured to receive a video stream, the video stream including a plurality of video frames. A video processor is configured to receive auxiliary data corresponding to the video stream, the auxiliary data including the information indicative of at least one video frame of the plurality of video frames. The video processor is further configured to modify the video frame in accordance with the auxiliary data. The video processor uses the received auxiliary data to identify a portion of the at least one video frame, the portion being modified in the act of modifying the video frame, other portions of the at least one video frame not being so modified. The video processor applies a filter to the portion of the at least one video frame.
Abstract:
A system for dynamically adapting the communication characteristics of a multiple antenna system (MAS) with multi-user (MU) transmissions (defined with the acronym MU-MAS), such as a distributed-input distributed-output (DIDO) communication system. For example, a system according to one embodiment of the invention comprises: one or more coding modulation units to encode and modulate information bits for each of a plurality of wireless client devices to produce encoded and modulated information bits; one or more mapping units to map the encoded and modulated information bits to complex symbols; and a MU-MAS or DIDO configurator unit to determine a subset of users and a MU-MAS or DIDO transmission mode based on channel characterization data obtained through feedback from the wireless client devices and to responsively control the coding modulation units and mapping units.
