  • Methods and apparatus for efficient data distribution to a group of users
    Patent number: 8155580
    Abstract: Methods and apparatus for efficient data distribution to a group of users. In an aspect, a method is provided for distributing information. The method includes detecting one or more requests for the information, determining whether the information is to be broadcast, and transmitting the information in a broadcast transmission based on the determination. In another aspect, an apparatus is provided for distributing information. The apparatus includes a detector configured to detect one or more requests for the information, a determination module configured to determine whether the information is to be broadcast, and a transmitter configured to transmit the information in a broadcast transmission based on the determination.

  • Scalable video coding with two layer encoding and single layer decoding
    Patent number: 7995656
    Abstract: Some embodiments comprise a method of decoding a video bitstream that include receiving a first layer of data and a second layer of data, combining the received first layer data and the received second layer data, and decoding the combined data. Also, a method of video encoding that includes selecting data for encoding in a first layer and a second layer so as to allow decoding of the data in a single combined layer, and encoding the selected data in the first layer and in the second layer by encoding a coefficient in the first layer and encoding a differential refinement to the first layer coefficient in the second layer.

  • Method and apparatus for error recovery using intra-slice resynchronization points
    Patent number: 7929776
    Abstract: A method of video coding that includes encoding resynchronization point information, where the resynchronization point information includes information identifying a location of a resynchronization point within a section of a video bitstream and information for decoding the bitstream following the resynchronization point. Also, a method for decoding digital video that includes receiving an encoded bitstream including resynchronization point information, where the resynchronization point information includes information identifying a location of a resynchronization point and information for decoding the bitstream following the resynchronization point, decoding the received bitstream, and locating the resynchronization point in the bitstream based on the resynchronization point information.
