  • Channel server, channel prediction server, terminal, and method for fast channel switching using plurality of multicasts interoperating with program rating prediction
    Patent number: 8856282
    Abstract: Provided are a channel server, a channel prediction server, a terminal, and a method for a fast channel switching. The channel server may generate at least one delay multicast stream from an original multicast stream by applying a different delay value based on channel preference information, and may determine an optimal multicast stream from the at least one delay multicast stream, and transmit, to a terminal, response information associated with the optimal multicast stream in response to query information associated with the original multicast stream received from the terminal.
    Type: Grant

  • Apparatus and method for controlling multicast in multi hop networks
    Patent number: 8208465
    Abstract: Disclosed is a multicast controlling apparatus and method in a multi hop network. The multicast controlling apparatus in the multi hop network includes a packet determining unit to receive a packet from a group management query device or a station, and to determine whether the received packet is a group management protocol packet, a packet type distinguishing unit to distinguish a type of the received packet when the received packet is determined as the group management protocol packet, and a packet transmitting unit to transmit the packet to a second port excluding a first port that receives the query message, when the received packet is determined as the query message.

  • SYSTEM FOR PROVIDING MULTI-ANGLE BROADCASTING SERVICE
    Publication number: 20110080425
    Abstract: Provided is a system for providing a multi-angle broadcasting service. A transmission apparatus may transmit, to a reception apparatus, a plurality of source images photographed at a plurality of angles and a multi-screen image including the plurality of source images. The reception apparatus may receive the multi-screen image and decode a source image based on a user selection.
