  • Multi-dimensional coding for high-density storage media applications
    Patent number: 7359303
    Abstract: An asynchronous transfer mode digital document delivery system is provided. A customer premise unit is configured to permit a customer to order and receive a data stream. A buffer is coupled to the customer premise unit to store the data stream before transmitting the data stream to a customer. A server includes digital documents stored thereon for delivery to customers through a switched ATM network. A control mechanism is employed to control a data rate of the data stream between the server and the buffer to ensure maintenance of a steady data stream from the customer premise unit to a customer during a loss of a physical layer between the server and the customer premise unit.

  • Technique for communicating variable bit rate data over a constant bit rate link
    Patent number: 6956875
    Abstract: Variable bit rate information is transmitted across a transmission link (20) at a constant bit rate by multiplexing individual variable bit rate elementary data streams (161 and 162) into a composite data stream (18) having a constant bit rate. A receiving device (22) receives the constant bit rate stream but delays processing thereof by an interval typically a fraction of the transmission interval. Following the delay interval, the receiving device processes the data at a rate that is independent of, but typically not greater than, the constant bit rate.
