20110032984 | Methods circuits and systems for transmission of video - Disclosed are methods, circuits and systems for transmission of a video block. A video stream may be composed of sequential video frames, and each video frame may be composed of one or more video blocks including a set of pixels. Prior to transmission of the data associated with a video block, a signature of the video block may be generated, for example using a spatial to frequency transform such as a two dimensional discrete cosine transform. Signatures of corresponding video blocks across consecutive video frames may be compared in order to determine whether a given video block of a current video frame is static or dynamic relative to prior video corresponding video blocks. Transmission parameters of the given block may depend on whether the block is designated as static or dynamic. | 02-10-2011 |
20110176618 | Device method and system for communicating data - Disclosed is a method, circuit and system for communicating data. A data value to be transmitted from a data source transmitter or transceiver to a downstream receiver or transceiver may be Shannon mapped, by functionally associated processing/mapping logic, to a point on a shape within a higher dimensional plane. Different portions of the shape, for example branches of a spiral, may be designated by a portion or branch number. Coordinates of the Shannon mapping, or another descriptors, of the Shannon mapped point may be transmitted using analog transmission methods. A set of data values may be Shannon mapped and transmitted to a downstream receiver/transceiver in series. For each set of mapped and transmitted data values, processing logic may calculate a branch ambiguity resolution factor. The branch ambiguity resolution factor for each set of values may be transmitted to the downstream receiver/transceiver before, after or with the data values. Decoding logic associated with the downstream receiver/transceiver may then use the branch ambiguity resolution factor to convert/decode received coordinates associated with the set of values into the data values. | 07-21-2011 |
20110274201 | DEVICE, METHOD AND SYSTEM OF WIRELESS COMMUNICATION OVER AN EXTREMELY HIGH RADIOFREQUENCY BAND - Disclosed is a method, circuit and system for wireless communication, including communication in an extremely high radio frequency range.

20120105729 | Methods circuits devices and systems for wireless communication of video information - Disclosed are methods, circuits, devices systems for wireless communication of video information. According to some embodiments, an energy level of one or a group of transmit video block(s) to be transmitted as part of a wireless transmission frame may be adjusted so at to maintain a substantially constant transmission power (e.g. within a range of transmission power levels) | 05-03-2012 |
20120317603 | Methods circuits & systems for transmitting and receiving data, including video data - Disclosed are methods, circuits, apparatus, devices and systems for transmitting and receiving data, including video data. All or some portions of a video frame (i.e. video block) may be processed and/or converted into frequency domain coefficients (e.g. DCT, DFT, etc.). Some or all of the frequency domain coefficients may be encapsulated within a transmission frame (e.g. an OFDM based transmission frame) and may be transmitted to a functionally associated receiver over a transmission channel. Not all frequency coefficients may be encapsulated and transmitted, possibly due to bandwidth limitations on the transmission channel. Selection (i.e. allocation) of one or more frequency coefficients to be transmitted may be based on a Visual Quality Metric (VQM) of the associated video block, such that encapsulation and transmission preference/priority may be given to maximize the VQM of the video block. A higher video block VQM may result in a lower transmitted distortion. | 12-13-2012 |
20130259140 | CIRCUIT, DEVICE, METHOD AND SYSTEM FOR TRANSMITTING VIDEO DATA BETWEEN A VIDEO SOURCE AND A VIDEO SINK - A method, circuit and system for transmission, receiving and processing of video data between a video source transceiver and a video sink transceiver. Video data or information to be transmitted, which instructs an image processor associated with a video sink to modify a previously video frame into a current frame. A Delta Frame may include one or more Grid Based Predicted Error (“GBPE”) Values. The GBPE may be generated by source-side image processing logic using processes or techniques similar to those described in the MPEG and/or H.264 Standards, with the exception that the prediction error values may be calculated relative to a noisy predicted frame (e.g. based on an analog reception of a base frame) which has been grid quantized based on video sink transceiver SNR (e.g. substantially each pixel value in the predicted frame is rounded off up or down to a value on some grid). | 10-03-2013 |
20140355501 | Systems and Methods for Sleep Mode and Staged Connectivity in Multi-RAT Environments - Systems and methods for staged connectivity and sleep mode are provided. Embodiments of the present disclosure optimize power consumption for a user across user devices by creating an ad hoc co-located network of user devices and establishing a device in the co-located network to act as a master (hub) device. In an embodiment, the system includes multiple user wireless devices and a network controller. The network controller identifies a set of proximate wireless devices and the power capability for each wireless device in the set. The network controller then selects a wireless device in the set to act as the hub (master) wireless device based on factors such as the power capabilities of each wireless device. The network controller then instructs the other wireless devices in the set to power down and instructs the appropriate network providers to handover communications to the hub (master) device. | 12-04-2014 |

20100014584 | Methods circuits and systems for transmission and reconstruction of a video block - Disclosed is a method, circuit and system for transmission and reconstruction of a video block. A video stream may be composed of sequential video frames, and each video frame may be composed of one or more video blocks including a set of pixels. Prior to transmission of the data associated with a video block, the video block data may be transformed into a set of transform (e.g. frequency) coefficients using a spatial to frequency transform such as a two dimensional discrete cosine transform. Selection of the subset of transform coefficients to be transmitted may be based on a characteristic of the video block. | 01-21-2010 |
