Abstract

An entertainment system has a personal computer as the heart of the system with a large screen VGA quality monitor as the display of choice. The system has digital satellite broadcast reception, decompression and display capability with multiple radio frequency remote control devices which transmit self identifying signals and have power adjustment capabilities. These capabilities are used to provide context sensitive groups of keys which may be defined to affect only selected applications running in a windowing environment. In addition, the remote control devices combine television and VCR controls with standard personal computer keyboard controls. A keyboard remote also integrates a touchpad which is food contamination resistant and may also be used for user verification. Included in the system is the ability to recognize verbal communications in video signals and maintain a database of such text which is searchable to help identify desired programming in real time.

Claims

1. A computerized method for processing video signals, the method comprising:

separating textual information from the video signals, wherein the textual information includes program information identifying future video signals to be received, said textual information identifying a start time for the future video signal;

storing the textual information in a database;

receiving a query;

searching the stored textual information in accordance with the query and retrieving text that matches the query for presentation of program information identifying future video signals to a user; and

storing the future video signals into a memory at the start time.

2. The computerized method of claim 1, wherein storing the textual information in a database stores a predetermined amount of textual information as received from said video signals in a fifo buffer, and stores new information over the oldest information such that a user may query the stored textual information for video programming related to a current event.

3. The computerized method of claim 1, wherein separating the textual information comprises separating closed caption text.

4. The computerized method of claim 1, wherein separating the textual information comprises separating program information contained in the vertical blanking interval of the video information.

5. The computerized method of claim 1, further comprising recording at least one subsequent episode of a series of programs included in identifying programming information that matches the query.

6. The computerized method of claim 1, wherein the query comprises queries selected from the group consisting of:

proximity searches, queries by example, and wildcard letters.

7. A computer-readable medium having store thereon computer-executable instructions for performing a method for processing video signals, the method comprising:

separating textual information from the video signals, wherein the textual information includes program information identifying future video signals to be received, said textual information identifying a start time for the future video signal;

storing the textual information in a database;

receiving a query;

searching the stored textual information in accordance with the query and retrieving text that matches the query for presentation of program information identifying future video signals to a user; and

storing the future video signals into a memory at the start time.

8. The computer-readable medium of claim 7, wherein storing the textual information in a database stores a predetermined amount of textual information as received from said video signals in a fifo buffer, and stores new information over the oldest information such that a user may query the stored textual information for video programming related to a current event.

9. The computer-readable medium of claim 7, wherein separating the textual information comprises separating closed caption text.

10. The computer-readable medium of claim 7, wherein separating the textual information comprises separating program information contained in the vertical blanking interval of the video information.

11. The computer-readable medium of claim 7, wherein the method further comprises recording at least one subsequent episode of a series of programs included in identifying programming information that matches the query.

12. The computer-readable medium of claim 7, wherein the query comprises queries selected from the group consisting of:

proximity searches, queries by example, and wildcard letters.

13. A computerized method for processing video signals, the method comprising:

separating electronic program guide (EPG) information from the video signals, said EPG information identifying a start time for a fuure video signal;

storing the textual information in a database;

receiving a query;

searching the stored textual information in accordance with the query and retrieving text that matches the query for presentation of program information identifying future video signals to a user; and

storing the future video signals into a memory at the start time.
