  • Patent number: 7031306
    Abstract: Transmitting data packets received from a non-constant delay medium includes storing the data packets in a buffer, determining a play-out schedule for the data packets based on timing information in the data packets, and transmitting the data packets from the buffer in accordance with the play-out schedule. Two of the data packets may contain time-stamps and the play-out schedule may be determined based on a difference between the time-stamps.
    Type: Grant
    Filed: March 22, 2001
    Date of Patent: April 18, 2006
    Assignee: Artel Video Systems, Inc.

  • Patent number: 6088360
    Abstract: A video multiplexer is disclosed which incorporates a dynamic rate control feature. MPEG encoded video signals for each channel are stored in a first-in first-out (FIFO) buffer. A packetizer for each channel detects the level in the FIFO buffer and issues a request signal to the video multiplexer that the channel desires to transmit the video signals on the network. The bandwidth allocation for a channel is either preselected by the video provider or automatically selected, and tokens are issued by a counter associated with each channel to give greater network access to those channels which require a higher bandwidth. A token multiplier detects the bandwidth needs of the various channels by detecting the rate that the FIFO buffer is being filled and automatically multiplies the number of consecutive packets which the packetizer may transmit over the multiplexer during a single grant.
