Publication number: 20070277221Abstract: Personal multimedia devices can detect when an incoming video format is different from a native format and make a local decision to convert incoming video formats to a format native to the personal multimedia device. The personal multimedia device may include a media processor that comprises an MPEG decoder/encoder, graphics processors, and a video decoder/encoder. These components increase a frame rate of a received video signal when the frame rate of the received video signal is less than a frame rate of the native video format of the personal multimedia device and decrease the frame rate of the received video signal when the frame rate of the received video signal is greater than the native frame rate of the set-top box. The graphics processor scales a frame resolution of the frames in the received video signal to correspond to the native video format.Type: ApplicationFiled: July 17, 2007Publication date: November 29, 2007Inventors: Robert Davis, Kuriacose Joseph, Ernest Seah

Publication number: 20060047749Abstract: A videoconferencing and data collaboration system is disclosed, wherein user systems exchange A/V data along with other computer data via conferencing devices over a packet network. The conferencing devices are configured to process and transmit A/V data to other devices participating in a conference. Each transmitting conferencing device uses DSP to encode A/V for transmission to the packet network. Once A/V data using the DSP is received, each receiving conferencing device decodes the A/V data and forwards it to a respective terminal for viewing via the digital link. The conferencing devices also share computer data and files over the digital network, where user modifications are tracked by transmitting short messages that indicate key depression or mouse movement.Type: ApplicationFiled: August 31, 2004Publication date: March 2, 2006Inventors: Robert Davis, Kuriacose Joseph, Ernest Seah

Patent number: 6961430Abstract: A method and apparatus for enabling background caching of encrypted programming data on a storage medium for later playback in a digital video recorder (DVR) system. A set-top box (STB) equipped with a DVR searches a program guide for upcoming pay-per-view (PPV) events. When the PPV event begins, the STB tunes an appropriate transponder and begins receiving programming data packets containing audio, video, system time and conditional access data packets associated with the event, which are stored for playback on a storage medium. When the user turns the STB on and selects an option to playback a previously-recorded PPV event, the appropriate programming data is retrieved from the storage medium, and the STB recreates the original transmission timing of the data, to be displayed on a display device of the user.Type: GrantFiled: October 30, 2000Date of Patent: November 1, 2005Assignee: The DIRECTV Group, Inc.Inventors: T. Paul Gaske, Walter R. Kepley, Scott Casavant, Kuriacose Joseph

Publication number: 20040268408Abstract: An approach is provided for distributing multi-media information from a satellite broadcast system. A hub receives a signal from the satellite broadcast system, wherein the signal represents video information and audio information associated with multiple broadcast channels. The hub centrally demodulates and decodes the received signal for distribution to one of a number of access point devices. According to one embodiment of the present invention, the decoded signal represents uncompressed video and audio information corresponding to one of the broadcast channels. The access point devices convert the received decoded signal for output respective displays (e.g., television sets). The hub can also be equipped with an interface to provide access to a public data network, such as the global Internet. Further, the hub can be supplied with a digital video recording capability.Type: ApplicationFiled: May 12, 2004Publication date: December 30, 2004Applicant: The DIRECTV Group, Inc.

Patent number: 6308280Abstract: A method and apparatus for synchronizing downstream circuit boards with the clock values transmitted in the incoming bitstream of a digital broadcast data signal from a digital satellite system (DSS) or digital video broadcast (DVB) is disclosed. The disclosed embodiments use the generation of quasi-periodic interrupts which latch, at the same time for all downstream circuits, local clock times.

Patent number: 5581706Abstract: A method and apparatus for generating an interactive component data stream, representing an application program, for an audio video interactive (AVI) composite signal, is disclosed. The method comprises the following steps. First, program files representing the application program are generated. Then, flow data defining the data structure of the interactive component is generated. Finally the data stream is generated by selectively inserting program files into the data stream in response to the flow data. Apparatus for generating such an interactive component data stream comprises a source of program files representing the application program and a source of flow data defining the data structure of the interactive component. A flow builder selectively inserts files from the source of files into the interactive component in response to data from the flow data source.Type: GrantFiled: June 30, 1994Date of Patent: December 3, 1996Assignee: RCA Thomson Licensing CorporationInventors: Ansley W.

Patent number: 5548532Abstract: Apparatus and a method for formatting executable codes and data, defining interactive applications, with video and audio program material, for reliable and convenient access includes compressing (18, 21) audio and video programs according to a protocol such as MPEG. The compressed audio and video (A/V) programs are segmented (19, 22) into transport packets, with audio transport packets identified by a first service identifier SCID.sub.Ai, and video transport packets identified by a second service identifier, SCID.sub.Vi. Interactive application programs associated with A/V programs are compiled (10) into functional modules and condensed. A module may be executable software or data. A module includes code/data and a header. The code/data portion of each module undergoes cyclic redundancy coding (CRC) over the entire module and CRC check bits are concatenated or appended to the module. Respective modules are segmented (14) into transport packets.Type: GrantFiled: April 28, 1994Date of Patent: August 20, 1996Assignee: Thomson Consumer Electronics, Inc.Inventors: Jean-Rene Menand, Kuriacose Joseph, Ansley W.
