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 controlbetween common consumer electronic (CE) devicesis provided. This interoperability is based on the IEEE 1394 serial bus forthe physical and link layers and makes use of AV/C or CALas the control language. This invention provides for transferring a bitmappedon-screen display menu constructed by a target device (e.g.,digital VCR) to display device (e.g., digital TV).
