  • Publication number: 20090064242
    Abstract: A method for digital video distribution in which a program is transmitted as a multicast stream over a network at a base rate. The stream includes a sequence of frames encoding video data, the sequence containing anchor points. A request from a client to begin receiving the program is received at a time subsequent to a given anchor point in the multicast stream. Responsively to the request, a boost stream is transmitted to the client beginning from the given anchor point at an accelerated rate relative to the base rate. The boost stream causes the client to display the video data beginning from the given anchor point and then to join the multicast stream when the boost stream has reached a point of synchronization with the multicast stream.

  • Patent number: 7412149
    Abstract: A method for generating a trick replay video stream, including the steps of: selecting from stored data adapted for transmission as a streamed movie a sequence of Intracoded frames (I-frames), and inserting one or more difference frames between consecutive I-frames of the sequence to form the trick replay video stream. Each of the difference frames is constructed to have a zero difference with respect to a preceding I-frame in the sequence. The method further includes transmitting the trick replay video stream to a decoder for display of the streamed movie at an enhanced perceived rate.
