  • System and method for providing a variable frame rate and adaptive frame skipping on a mobile device
    Patent number: 8279946
    Abstract: A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.

  • Method and system for multicast video streaming over a wireless local area network (WLAN)
    Patent number: 8270425
    Abstract: A system and method for multicast video streaming over a wireless local area network (WLAN) improves scalability and reliability. The method includes configuring the WLAN access point with a reserved video bandwidth (step 1005). A multicast video stream including data packets marked with differentiated services code points (DSCPs) is then received (step 1010). The multicast video stream is then converted to a plurality of “n” unicast streams (step 1015). Data packets in the unicast streams are then streamed from the WLAN access point to a plurality of “n” mobile units using a selective packet discard algorithm that employs the DSCPs (step 1020).

  • Method and apparatus for resource allocation in a shared wireless network
    Patent number: 8233449
    Abstract: Resource allocation is performed in a shared wireless network that includes multiple cells, a shared wireless network QoS manager, and multiple local QoS managers. The shared wireless QoS manager receives from multiple ones of the local QoS managers on a per cell and per QoS service class basis (for a plurality of QoS service classes): an aggregation of current cell usage estimations; an aggregation of cell load level indicators, and an aggregation of additional resources needed. Using this received information, the shared wireless network QoS manager: determines a total capacity of each cell that is needed to satisfy a total resource need on a cell by cell basis for the local QoS managers; and based on a maximum capacity for each cell, allocates to each local QoS manager a percentage of their total resource need.

  • Systems and methods for transporting data across an air interface using reduced address headers
    Patent number: 8223771
    Abstract: Systems and methods are disclosed for transporting data across an air interface using a blending of protocol layers to achieve reduced bandwidth. Advantage is taken of the fact that the extra overhead from, for example, the Ethernet protocol is addressing information pertaining to the destination of the packet. This destination information (for example, the Ethernet address) can be stripped from the transmission prior to the air interface and recreated after the air interface. In one embodiment, the concepts of a proper Layer 2 CS are merged on top of the 802.16 protocol and still retain the benefits of a Layer 2 transparent bridged service layer to the network layer. In one embodiment, the MAC address of the destination is used for the air interface and the Ethernet address is recreated and added on the far side of the air interface.
