Filed:

Dec 18, 1999

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:

Gemstar Development Corporation

International Classification:

H04N007/16

US Classification:

725/025000

Abstract:

A television control system automatically tunes a television set to receive and display a desired program telecast at a future time. This is done by keying in a PLUS CODE™ number defining the channel, time, day, and length (CTDL data) of the program or selecting the program from an on-screen program guide to capture the CTDL data from an EPG data base stored in memory. The CTDL data is stored in a stack memory until the time of the program. The microprocessor monitors the stack memory. The microprocessor tunes the television set to the channel on which the desired program is telecast and turns the television set on at the time of the desired program. If the television set is already on at the time of the desired program, the television set is not turned off at the conclusion of the desired program, i.e., it remains on. However, if the television set is off at the time of the desired program, the television set is turned off again at the conclusion of the desired program. This results in the television set not being left on when the residents are away from home while the scheduled tuning feature is being used.

International Classification:

G11B 528

US Classification:

427555

Abstract:

A process for creating a "distant bump array" surface texture in a magnetic recording disk for reducing stiction and the disk so textured. The texturing process uses a tightly focused diode-pumped Nd:YLF or Nd:YVO. sub. 4 or other solid-state laser that is pulsed with a 0. 3-90 nanosecond pulse train to produce a plurality of distantly-spaced bumps in the disk surface. The bump creation process is highly controllable, permitting repeated creation of a preselected bump profile such as a smooth dimple or one with a central protrusion useful for low stiction without close spacing or elevated "roughness". Some bump profiles permit texturing of the data-storage region of the disk surface for low stiction without materially affecting magnetic data storage density.
