Appl. No.:

09/467538

Inventors:

Henry C. Yuen - Pasadena CA
Wing P. Leung - Arcadia CA

Assignee:

Index Systems, Inc.

International Classification:

H04N 576

US Classification:

386 46, 386 83, 386 95

Abstract:

A video tape indexing system in which program broadcast identification information is entered into the system for use in recording the program. When the program is recorded, the system stores indexing information in an index memory. The system monitors a broadcast channel for electronic program guide information that includes titles and usually channel, date, time and length for the titles. The system matches the channel, date, time and length information from the broadcast channel with the identification information entered for the program to be recorded. The title in the broadcast channel associated with the channel, date, time and length information is then associated with the indexing information for the program.

International Classification:

H04N 7/16

US Classification:

725 30, 725 47, 348553

Abstract:

A method and apparatus for exercising access control over television programs using a parental control user interface that has different functions is provided. The method requires a password to enter into a master mode for obtaining access to all the functions of the parental control user interface. Once in the master mode, the user may enter a criterion for blocking a television program from being viewed or recorded or the user can override an already blocked television program. If a user, not in the master mode, attempts to watch or record a program that meets the blocking criterion and the program does not meet the overriding criterion, a prompt is provided to the user to enter the password. Upon entering a correct password, the program is unblocked.

Assignee:

Index Systems, Inc.

International Classification:

H04N 7088

US Classification:

348478

Abstract:

Apparatus and methods are provided for inserting data into a vertical blanking interval (VBI) line of video frames. The method includes the steps of inserting first data into a first vertical blanking interval VBI line for a plurality of consecutive video frames, inserting second data into a second vertical blanking interval VBI line for a plurality of consecutive video frames, counting a number of consecutive video frames having first data inserted into the first vertical blanking interval VBI line, terminating the insertion of first data for a first number of video frames before again inserting first data into the first vertical blanking VBI interval line when the counted number of consecutive video frames into which first data is inserted into the first vertical blanking interval VBI line equals a second number, and repeating the steps. In a specific embodiment the method includes the steps of detecting when the insertion of second data into the second vertical blanking interval VBI line terminates, and terminating for a second number of video frames the insertion of first data into the first vertical blanking interval VBI line upon detecting the termination of insertion of the second data into the second vertical blanking interval VBI line. Another method for inserting data into VBI lines includes the steps of testing whether data is being inserted into a first VBI line, and inserting any data into VBI lines adjacent to the first VBI line in 2X format rather than 1X format, if data is being inserted into the first VBI line.
