Publication number: 20080127277Abstract: A network bridging system, which receives RF (radio frequency) broadcast digital audio/video and encapsulates and routes selected broadcast content across a Local-Area-Network (LAN). The system includes multiple tuners that allow multiple client devices to access the broadcast content simultaneously through a network connection. It serves as a standalone Ethernet server and does not require a connection to a PC. The broadcast content, encapsulated in unicast or multicast network packets, is shared among multiple users concurrently.Type: ApplicationFiled: September 15, 2006Publication date: May 29, 2008Applicant: PIONEER RESEARCH CENTER USA, INC.Inventor: Brian Kuschak

Publication number: 20060218584Abstract: A method of filtering an electronic program guide (EPG) information is disclosed. EPG information is retrieved from an EPG provider. The EPG information is filtered to retain program information related to programs delivered by a content delivery provider to a subscriber. The content delivery provider is different from the EPG provider.Type: ApplicationFiled: March 3, 2005Publication date: September 28, 2006Applicant: PIONEER RESEARCH CENTER, USA, INC.Inventor: John Gildred

Publication number: 20060168625Abstract: One embodiment of the invention is a technique to stop recording a program intelligently. Stopping recording a program is delayed from a scheduled stop recording time. A transition between the program and a commercial is detected after the scheduled stop recording time. Recording the program is stopped at the detected transition. Another embodiment of the invention is a technique to start recording a program intelligently. Starting recording a program is advanced from a scheduled start recording time. A transition between a commercial and the program is detected within a recording window before the scheduled start recording time. Recording the program is started if the transition is detected within the recording window.Type: ApplicationFiled: January 25, 2005Publication date: July 27, 2006Applicant: PIONEER RESEARCH CENTER USA, INC.Inventor: John Gildred

Publication number: 20060156342Abstract: One embodiment of the invention is a technique to generate consistent timing data for an electronic program guide (EPG). Time information is extracted from a broadcast stream received by a receiver. The time information is based on a first timing reference. The time information is adjusted with respect to a second timing reference used by an electronic program guide (EPG) obtained by the receiver.Type: ApplicationFiled: January 11, 2005Publication date: July 13, 2006Applicant: PIONEER RESEARCH CENTER USA, INC.Inventor: Wendy Xiao

Publication number: 20060104611Abstract: One embodiment of the invention is a technique to resolve recording conflict in program recording. A conflict is detected in recording first and second programs. The conflict is caused by an overlapping segment occupying a time period common to desired recording times of the first and second programs. A user is allowed to select recording the first program without the overlapping segment.Type: ApplicationFiled: November 15, 2004Publication date: May 18, 2006Applicant: PIONEER RESEARCH CENTER USA, INC.Inventors: John Gildred, Victor Vedovato

Publication number: 20050166227Abstract: In a terrestrial broadcast system, a program manager filters program data via a first tuner while a second tuner receives one of audio or video information of a channel from a transport stream. The program data is then parsed for channel information. The channel information is stored in a database.Type: ApplicationFiled: January 27, 2004Publication date: July 28, 2005Applicant: PIONEER RESEARCH CENTER USA, INC.Inventor: Anirudh JOSHI

Publication number: 20050149478Abstract: The present invention is directed to minimizing the dependency of source code on the characteristics of a set-top box's in-band (streaming video or audio) hardware. The set-top box software consists of a device driver layer, which is intimately aware of hardware characteristics, an application layer, which is relatively unaware of any hardware details, a middleware layer which is also relatively unaware of any hardware details, and a device translation layer (DTL). In the DTL, all of the translation between device abstractions to device driver calls that were formerly made in middleware are moved down to an engine manager. Middleware thus becomes device-independent with respect to in-band devices, and porting Middleware to new hardware becomes trivial.Type: ApplicationFiled: August 10, 2004Publication date: July 7, 2005Applicant: Pioneer Research Center USA, Inc.Inventor: James Fahy

Publication number: 20040117626Abstract: A first certificate is provided from a first peer to a second peer. The first certificate includes a plurality of first parameters. A first exponentiation operation is performed to generate a first public key from the second peer using the plurality of first parameters and the first private key from the second peer. A second certificate and the first public key from the second peer are provided to the first peer. The second certificate comprises a plurality of second parameters. A second exponentiation operation is performed to generate a shared secret key for the second peer using at least one parameter from the plurality of first parameters. A third exponentiation operation is performed to generate the shared secret key for the first peer using the first public key from the second peer and a private key from the first peer.Type: ApplicationFiled: September 12, 2003Publication date: June 17, 2004Applicant: PIONEER RESEARCH CENTER USA, INC.Inventor: ASHOT ANDREASYAN
