Method and apparatus for displaying textual or graphic data on the screen of television receivers
First Claim
1. A system for displaying textual or graphic data on a television receiver comprising:
- a memory device at the television receiver in which data representing local language commands is stored;
a microprocessor electrically coupled to the memory device for displaying the local language commands stored in the memory device on the television receiver;
a VBI decoder for extracting data from a VBI of a television signal, wherein the extracted data includes commands, in one or more foreign languages, corresponding to the local language commands; and
a storage device at the television receiver for storing the extracted data, wherein the microprocessor is configured to substitute the commands in one or more foreign languages for the local language commands for displaying on the television receiver.

Abstract
A local language is pre-stored in permanent memory. Equivalent data is transmitted in the vertical blanking interval (VBI) to television receivers. Each equivalent data set comprises a unique language identifier and a foreign language translation of, or graphical representative of, the local language pre-stored in permanent memory. The viewer selects the language to be displayed from an on screen menu with a remote controller. The selected equivalent data is retrieved from the VBI and stored in a RAM for future display. When the microprocessor calls up the text of a command for display, the equivalent data is substituted for the local language data so the foreign language version of the command can be displayed in a seamless manner. If no equivalent data is in the RAM, the local language pre-stored in permanent memory is displayed on the television screen in accordance with the normal operation of the microprocessor.
