Apparatus and method of searching for desired television content
First Claim
1. A method of identifying a real-time television signal of interest to a user, the method comprising:
- the user entering a search parameter into a logical unit;
simultaneously buffering a plurality of audio voice streams of a plurality of real-time television signals in a plurality of languages;
translating the plurality of audio voice streams into text associated with each of the plurality of real-time television signals in said plurality of languages;
buffering the text into a lexical buffer;
searching said lexical buffer for the search parameter;
displaying a list of said plurality of real-time television signals in said plurality of languages in order of relevance to the search parameter; and
the user selecting a first real-time television signal from the list, whereby the first real-time television signal is displayed on a television in real-time;
wherein the user specifies said plurality of real-time television signals, an amount of buffering time to be allocated for each of the plurality of real-time television signals, and a plurality of time periods for each of the plurality of real-time television signals to be buffered.

Abstract
The present invention is an apparatus and method for allowing a user to search for specific content across many television channels in order to locate desirable television shows related to the searched content. Multiplexed cable signals flow thorough a logical unit which buffers text associated with the voice stream of each station via the pre-encoded closed-captioning signal or through the real-time voice translation within the logical unit. The user then enters search terms through one of a variety of different input devices. Upon entry of the search terms, the logical unit will compare the entered term with those available keywords stored in each buffer. Lexical parsing associates terms which may differ from plural to singular forms, or in tense. Additionally, synonym comparisons may be made. The logical unit will return a list of matches for the search criteria and allows the user the option of going directly to the television program. The logical unit also evaluates each returned item for its relevancy to the keywords. When not in use, the logical unit maintains a quiescent but monitoring state permitting continuous creation of lexical buffers. This permits the user who turns the television on to immediately have such search terms available. Alternatively, the logic is implemented at the cable provider and enabled through interactive links to the home. In that case, the home logical unit is unnecessary.
