  • Patent number: 11706323
    Abstract: Embodiments include methods for managing a reordering timer performed by a processor of a wireless device. The processor may receive packets from a communication network and store the packets in a memory buffer of the wireless device. The processor may detect one or more conditions that affect an amount of time required to reorder or reassemble at least some of the packets received from the communication network. The processor may determine a timer adjustment based on the detected one or more conditions. The processor may adjust a timer with the determined timer adjustment. The processor may deliver one or more packets from the memory buffer in response to expiration of the adjusted timer.

  • Patent number: 10707851
    Abstract: A double data rate circuit includes a clock generator, a clock divider and a multiplexer. The clock generator is used to receive a source clock signal to generate a pair of complementary clock signals. The clock divider is coupled to the clock generator, and used to generate four multiphase clock signals using only single-edge transitions of the pair of complementary clock signals. The four multiphase clock signals are successively out-of-phase by 90°. The multiplexer is coupled to the clock divider, and used to multiplex multiple data bits into an output data stream by sequentially selecting and deselecting each data bit of the multiple data bits upon a first edge transition of and a second edge transition of two of the four multiphase clock signals, respectively, and outputting each selected data bit as the output data stream.

  • Patent number: 9916540
    Abstract: Scalable-effort machine learning may automatically and dynamically adjust the amount of computational effort applied to input data based on the complexity of the input data. This is in contrast to fixed-effort machine learning, which uses a one-size-fits-all approach to applying a single classifier algorithm to both simple data and complex data. Scalable-effort machine learning involves, among other things, classifiers that may be arranged as a series of multiple classifier stages having increasing complexity (and accuracy). A first classifier stage may involve relatively simple machine learning models able to classify data that is relatively simple. Subsequent classifier stages have increasingly complex machine learning models and are able to classify more complex data. Scalable-effort machine learning includes algorithms that can differentiate among data based on complexity of the data.

  • Patent number: 8559469
    Abstract: A system and method for voice transmission over high level network protocols. On the Internet and the World Wide Web, such high level protocols are HTTP/TCP. The restrictions imposed by firewalls and proxy servers are avoided by using HTTP level connections to transmit voice data. In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses in human speech, thus reducing the delays in transmission caused by using HTTP/TCP. The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.

    Abstract: The invention is intended to reduce overall image degradation when frame interpolation is performed by means of an adaptive image compression technique. A compression unit which adaptively compresses input image data, determines an error rate, i.e., a quantity of data loss, depending on input image data. A compression rate is set, depending on the determined error rate (or the quantity of data loss). For an image that is likely to be degraded by compression because of a large error rate determined for it, a process of generating an interpolated image by an interpolated image generating unit is disabled and an original image is used instead of an interpolated frame.

In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses in human speech, thus reducing the delays in transmission caused by using HTTP/TCP. The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.

  • Patent number: 8111721
    Abstract: A multiplexing system (10) is provided which includes a plurality of encoders (12-15) which generates elementary streams, respectively, CPU (16), multiplexer (17), instruction memory (18), and a data memory (19) which stores a plurality of elementary data to be multiplexed. Each of the encoders (12-15) divides elementary data into units, and stores the data into the data memory (19). The CPU (16) generates, for each of the data units, instruction data having stated therein a storage location in the data memory (19) and stores the instruction data into the instruction memory (18). The multiplexer (17) reads the instruction data one by one from the instruction memory (18), and reads data units stated in the instruction data sequentially from the data memory (19), for generation of a multiplexed stream. Thus, the burden of processing to the controller can be lessened.

  • Patent number: 8098612
    Abstract: A satellite broadcasting system is achieved in which remote beam forming processors located among distributed ground stations are used to control downlink beam footprints and pointing directions. Digital beam forming techniques allow a single satellite downlink broadcast antenna array to generate multiple simultaneous downlinks that can be pointed independently and that may contain distinct information content. By allocating some of the uplink back-channel elements as null channels, continuous calibration of the uplink channel can be performed, improving the performance of the downlink broadcast array and the quality of the broadcast for users. By wavefront multiplexing, all of the uplink channel elements propagate through the all of the available propagation channels simultaneously, eliminating the need for complex and costly individual array-element calibration equipment using on-board or ground-based references.

  • Patent number: 7894491
    Abstract: A data transfer circuit is provided for sending digital data at high rates across short but significant distances within an integrated circuit. The data is sent on parallel conductors that are divided into a number of groups. At the receiving end, a multiplexer selects each of the groups in turn and presents them at a set of conductors that are the same in number as one of the groups. At the transmitting end, a data marshalling circuit takes the bitstream to be transmitted and places it on the conductors in a particular redundant fashion so that the bitstream appears to advance across the set of outputs of the multiplexer. That is particularly useful where those outputs are presented to a pre-emphasis filter and line driver. The apparent data rate can be changed by making two or more of the groups of conductors have identical data.
