US Patent:

20020188956, Dec 12, 2002

Filed:

Dec 17, 2001

Appl. No.:

10/022049

Inventors:

Michael Ficco - Silver Spring MD, US
Lou King - Ijamsville MD, US
Sean Lee - Potomac MD, US

International Classification:

H04N007/173
H04N007/16

US Classification:

725/110000, 725/139000, 725/131000, 725/151000, 725/134000, 725/142000

Abstract:

A method and system which temporally sorts data such as program guide data for example, to ensure that near-term data (i.e. most likely to be used, or “now data”) is always available for rapid access from a physical memory location such as a high-speed temporal cache. The method incorporates two low-priority background processes or algorithms, termed “event horizons” into the storage and manipulation of the data so that applications using the data may be run without having to always access a mass storage device. The method and system are highly applicable to all set top boxes (STBs) used in various communication systems such as satellite communication, Cable-TV and DVB systems. The method and system are economical in that superior STB and/or system performance may be obtained with the inclusion of lesser amounts of expensive high-speed RAM.

Appl. No.:

12/102362

Inventors:

Timothy E. Callaway - Laurel MD, US
Sean S. Lee - Rockville MD, US

International Classification:

H04N 5/91

US Classification:

386 83, 386E05001

Abstract:

A system and method of extending a recording time of a recording event within a receiving device is set forth. The receiving device includes a memory and a controller. The controller generates a recording event request for content having a start time and a first end time and begins to store content in a memory of the first receiving unit starting at the start time. The controller reviews a program associated characteristic of the content when the end time is reached and when the program associated characteristic corresponds to the content, changes the first end time to second end time later than the first end time.
