Method To Customize The Playback Of Compact And Digital Versatile Disks

View page
US Patent:
6813438, Nov 2, 2004
Filed:
Sep 6, 2000
Appl. No.:
09/656103
Inventors:
Cary Lee Bates - Rochester MN
Chih-Hsiang Chou - Cupertino CA
Jeffrey Michael Ryan - Byron MN
John Mathew Santosuosso - Rochester MN
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 585
US Classification:
386125, 386 52
Abstract:
A playback program for DVDs and CDs enables a user to customize the playback of the disk. Regions that are independent of prerecorded tracks are created and/or played back based on the content of the disk, e. g. , visual content or audio content, in those regions. Thus, for instance, certain scenes or certain dialogue of the disk can be skipped over during playback because an attribute to skip or otherwise modify the output was assigned to a particular region during creation of the program. Several start-up modes can be programmed during creation of the program to indicate whether the disk will initially skip to the first region whose output is modified or playback normally until a region with an modified output is encountered. A password may be required to access the playback program.

US Patent:
7346044, Mar 18, 2008
Filed:
Oct 14, 2002
Appl. No.:
10/271183
Inventors:
Chih-Hsiang Chou - Cupertino CA, US
Janardhana Reddy - Sinagpore, SG
Wee Sin Tam - Singapore, SG
Poh Yoke Lai - Singapore, SG

Assignee:
MediaRing Ltd. - Singapore Post Centre
International Classification:
H04L 12/66
US Classification:
370352, 370354
Abstract:
A network address translation apparatus and method within a Voice over Internet Protocol (VoIP) router is described. This apparatus and method operates within networking devices such as routers, switches, bridges, etc. These devices masks both source and destination addresses and may either replace or complement a firewall in providing security. According to one embodiment, network type information, corresponding to the gateways within connection, is embedded in a port number within a packet header. This network type information is extracted and analyzed to identify the network types of both gateways within the connection. According to another embodiment, a port number is assigned according to the network types of both gateways within a connection. Thus, this network type information may be identified by processing the port number on which a packet is received.
