Demultiplexing Single Signal Into Plural Parallel Channels (e.g., Parallel Transmission For Increasing Transmission Speed) Patents (Class 370/536)
  • Patent number: 10887659
    Abstract: A Video on Demand (VOD) service provides VOD offering in response to a graphical user interface (GUI) screen that renders a guide of available VOD offerings. A concurrent stream of promotional content is also rendered along with the VOD offerings, and displays various VOD offerings and advertising media, typically rendered in a screen portion adjacent the VOD guide offerings. Such promotional content is often referred to as “barker” content and is delivered over a barker channel that transmits in parallel with the VOD guide. Delivery of the VOD guide and associated barker channel content includes a redundant barker player and failover processing that identifies failed barker content transmission (streaming) and commences transmission from a standby barker player with minimal interruption to the rendered viewer experience.

  • Patent number: 10277424
    Abstract: Time, frequency and waveform division multiplex schemes are used to efficiently estimate multiple uplink channels in a Wireless Local Area Network (WLAN). Orthogonal Frequency Division Multiple Access (OFDMA) and multi-user Multiple Input Multiple Output (MU-MIMO) approaches provide efficient uplink data transmission. An Access Point (AP) communicates with multiple Stations (STAs) in the WLAN. In some approaches, two or more STAs are addressed and the two or more STAs respond at the same time. The AP receives a composite signal and separates the responses to estimate the uplink channel from each STA. After the AP learns the uplink channels, the AP triggers data transmission from one or more of the WLAN STAs by sending a synchronizing trigger message. In some embodiments, the STAs respond simultaneously with data transmissions to the AP.

    Abstract: Disclosed herein is an optical transport system configured to transport an amplitude-modulated optical signal generated at the transmitter using single-sideband modulation of an optical carrier and detected at the receiver using direct optical detection. The receiver is configured to estimate the level of signal-signal beat interference (SSBI) in the electrical signal generated upon direct detection of the received optical signal by first converting this electrical signal into a modified baseband signal configured for single-sideband modulation and then squaring and appropriately scaling this modified baseband signal. The receiver is further configured to subtract the estimated level of SSBI from the electrical signal generated by the direct optical detector and to process the resulting corrected electrical signal to recover the data encoded in the amplitude-modulated optical signal. Example analog and digital circuits for estimating the level of SSBI at the receiver are disclosed.

The second multiplexer outputs the third input data signal at a timing that coincides with the timing at which the second input data signal is output from the first multiplexer. At each given cycle, a third multiplexer, after outputting the first input data signal and the second input data signal output from the first multiplexer, outputs the third input data signal and the fourth input data signal output from the second multiplexer.

  • Patent number: 8817825
    Abstract: Methods and systems for processing signals in a receiver are disclosed herein and may comprise receiving spatially multiplexed signals via M receive antennas. A plurality of multiple data streams may be separated in the received spatially multiplexed signals to detect MIMO data streams. Each of the MIMO data streams may correspond to a spatially multiplexed input signal. Complex phase and/or amplitude may be estimated for each detected MIMO data streams utilizing (M-1) phase shifters. Complex waveforms, comprising in-phase (I) and quadrature (Q) components for the MIMO data streams within the received spatially multiplexed signals may be processed and the processed complex waveforms may be filtered to generate baseband bandwidth limited signals. Phase and/or amplitude for one or more received spatially multiplexed signals may be adjusted utilizing the estimated complex phase and amplitude. Phase and/or amplitude may be adjusted continuously and/or at discrete intervals.

  • Patent number: 8750337
    Abstract: An apparatus and method for managing a preference channel are provided which can reduce a delay time when a channel change is made between preference channels, by storing a preference channel directly selected by a mobile terminal user in a mobile broadcast system. A mobile terminal receives and demultiplexes multiplexed logical channels on which data streams are transmitted from a service provider through a communication network. Preference channels of the demultiplexed logical channels are dynamically allocated to decoding buffers using stored information. A decoding time at which data of the decoding buffers is accessed and decoded is computed using reference information. A decoding operation is performed at the computed decoding time, and decoded channel-by-channel elementary streams are stored in a memory. The decoded channel-by-channel elementary streams stored in the memory are displayed on a screen of the mobile terminal.

  • Patent number: 8750336
    Abstract: A method, system, and computer-readable media are provided for facilitating communication of multimedia data across a distributed network. When the invention is employed for facilitating intra-communication between mobile network carriers, the invention can be configured to utilize a plurality of distribution sites. A first distribution site of a sender can receive an item of multimedia data and an identifier from a sender. The first distribution site may then transmit the identifier to a look-up server in order for the look-up server to identify the location of a recipient's distribution site. Once the look-up server identifies the recipient's distribution site for the first distribution site, the first distribution site can transmit the multimedia data to the recipient's distribution site.

  • Patent number: 8705580
    Abstract: Extending wired networks by aggregating multiple wireless links. Multiple wireless links are used to bridge wired networks, such as wired Ethernet networks. Each wireless link applies a hash function to the destination MAC address of presented traffic and uses the result of the hash function to determine if the traffic is passed by that wireless link or is dropped. For broadcast and multicast frames, the hash function is calculated on the source MAC address. Dynamic source MAC rewriting may be performed to prevent port flapping or out-of-order arrival of frames. Establishing one link as a master and communicating among links allows for load balancing and link failure detection.
