Abstract:
1. For a digital television, a sound-guided operation device for sound-guided cursor navigation through onscreen electronic program guides, the sound-guided operation device comprising: a television-signal separating section for separating channel-tuned, broadcast-station-specific demodulated television-signal data, output from a tuner in the digital television, into video and sound signals, and attachment data including an electronic program guide for displaying a menu of channel-specific program and broadcast time information; a control section; a storage section storing base information and for storing current information, the base information and current information being broadcast-station information or broadcast-time information contained in the attachment data separated out by the television-signal separating section, loaded into the storage section by the control section, wherein the base information indicates cursor initial position, and the current information indicates cursor current position, on the electronic program-guide menu as displayed on the digital television; a cursor-operation information receiving section, operatively connected with the control section, for receiving cursor-operation information signals; an operation sound generation section for generating, under control by the control section, operation-indicating sound when the cursor is operated; a screen-rendering processing section, operatively connected with the control section, for rendering the electronic program-guide data and the cursor-operation information signals as video output signals superimposed onto the video signals separated by the television-signal separating section, for onscreen display by the digital television of the electronic program-guide menu and cursor movement relative to the menu; wherein the control section is configured to a sound-signal superimposing section for superimposing the operation-indicating sound generated by the operation sound generation section onto sound signals output to a speaker in the digital television.
