SYSTEM FOR PROVIDING INTEROPERABILITY BETWEEN DEVICES, INTERCONNECTED BY A DIGITAL BUS, UTILIZING BIT-MAPPED ON-SCREEN DISPLAY MENUS

摘要

Interoperability for exchanging on-screen display menus and associated contr ol 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 bitmappe d on-screen display menu constructed by a target device (e.g., digital VCR) to display device (e.g., digital TV).
