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. On-Screen Displays (OSDs) (e.g., menus) may be transferred from a peripheral device (for example, digital VCR) to a controller (for example, DTV) by sending one frame of video either using a push or pull method in conjunction with the asynchronous services of the IEEE 1394 serial bus via an isochronous channel.
