  • Patent number: 7349395
    Abstract: Systems, methods, and computer program products for parsing a packetized, multi-program transport stream are disclosed. A packetized, multi-program transport stream is received in a demultiplexer. Program specific information is extracted from the program stream and displayed on a user interface. A user may select a program from the program stream for further processing. The user interface generates a signal indicative of the selected program, and the demultiplexer output is configured based on the selection signal.

  • Patent number: 5834085
    Abstract: A new type of multilayer structure is shown which has superior properties for retaining magnetic transitions on a surface as they are written by a recording transducer. The multilayer is composed of crystal grains which are electronically isolated from one another (exchange isolated). The exchange isolation of the grains creates a type of medium which can viably store data at more than 2 billions bits per square inch. A method is described for making such a structure and the storage of magnetic transitions at extremely high density is demonstrated. Recording with previous multilayer candidates is also shown for comparison purposes.
