  • Device interoperability utilizing bit-mapped on-screen display menus
    Patent number: 7362381
    Abstract: Interoperability for exchanging on-screen display menus and associated control between common consumer electronic (CE) devices is provided. This interoperability is based on the IEEE 1394 serial bus for the physical and link layers and makes use of AV/C or CAL as the control language. This invention provides for transferring a bit-mapped on-screen display menu constructed by a target device (e.g., digital VCR) to display device (e.g., digital TV).

  • Digital television apparatus for controlling a peripheral device via a digital bus
    Patent number: 6665020
    Abstract: A minimal level of interoperability for exchanging audio/video (A/V) content and associated control between common consumer electronic (CE) devices is defined. This interoperability is based on the IEEE 1394 serial bus for the physical and link layers and makes use of AV/C or CAL as the control language. This invention provides for reducing the number of remote controls that the user might need by allowing remote control commands to always be received by a controlling device (e.g., digital television) and then routed to the appropriate peripheral device (e.g. digital VCR) after translation into a universal format.
