Patent number: 8364024Abstract: Video frames from a sequence of video frames and corresponding audio are received and processed by a media player. A first portion of the sequence depends on fewer reference frames then a second portion of the sequence. The number of reference frames per frame is limited. The first and second portions of the sequence are treated differently. The first portion is received at a lower data rate, with greater security and processed with a more robust protocol stack than the second portion. The first and second portions may be stored in a single queue and/or separate queues. The first portion of frame data is utilized to compensate for lost frames by repeating and/or interpolating video frames. The media player constructs a local video frame and synchronizes corresponding audio content with it. The received, repeated and/or interpolated video frames are assembled into display order and decoded.Type: GrantFiled: February 3, 2009Date of Patent: January 29, 2013Assignee: Broadcom CorporationInventors: James D.

Patent number: 8135263Abstract: Archival storage and retrieval of audio/video information is described. Audio and/or video information is digitized, compressed and stored in an intermediate archive format (IAF), which preserves the content at a high-enough quality for subsequent retrieval and conversion into various formats required at the time of use or distribution. A single capture operation is performed with ancillary metadata being added to facilitate subsequent searching, indexing and format conversion. Captured data content is catalogued and indexed at or subsequent to the creation of an IAF file that includes the archived information. The IAF includes a family of audio-video digital encoding formats based on public standards. The encoding format used in any particular application is determined at encoding time from information provided by the archive system user. At encoding, the particular encoding scheme is selected to optimize a tradeoff between storage constraints and end use quality requirements.Type: GrantFiled: September 8, 2006Date of Patent: March 13, 2012Assignee: Front Porch Digital, Inc.Inventors: Jay Yogeshwar, Stephen A.

Patent number: 8120675Abstract: A moving image recording/playback device records a moving image of a subject. In the case of recording, the moving image recording/playback device sequentially outputs a plurality of image frames that constitute the moving image at a predetermined frame rate and, for the plurality of image frames, records whole image frames at intervals of a predetermined number of frames and partly records other image frames, onto at least one recording medium. In the case of playback, when reading a partly recorded image frame, the moving image recording/playback device generates a display frame from the partly recorded image frame and a recorded whole image frame.Type: GrantFiled: October 16, 2007Date of Patent: February 21, 2012Assignee: Panasonic CorporationInventor: Masayoshi Tojima

Publication number: 20120002945Abstract: A transmitter (14) of audio, video, or other real-time information reads the information from a persistent store (22) in which the real-time information has been stored in the Real-time-Transport Protocol (“RTP”) format (FIG. 4). A receiver (18) receives the information from the channel (16) through which the transmitter (14) has transmitted it, and the receiver may store the information in a persistent store (24) in RTP format instead of or in addition to playing it by applying it to an appropriate player (20). Parts of this communications circuit may be tested by a tester unit (26) that also employs RTP-format information from a persistent store (22).Type: ApplicationFiled: September 15, 2011Publication date: January 5, 2012Inventor: Michael A.

Publication number: 20110305431Abstract: To provide means for editing a content data stream quickly. A data processor according to the present invention can edit a content that has been written on a medium. The content is stored in a file as a data stream including multiple packets of the same packet size. And a file system for accessing data on a cluster size basis has been established on the medium. The data processor includes: a receiving section, which receives an instruction on a partial deletion range including the beginning of the file; and a media control section for deleting data, the size of which is an integral number of times as large as the least common multiple of the cluster size and the packet size, from the beginning of the file within the partial deletion range.Type: ApplicationFiled: August 25, 2011Publication date: December 15, 2011Applicant: PANASONIC CORPORATIONInventors: Hiroshi YAHATA, Tomoyuki OKADA, Masanori ITOH

Patent number: 8068721Abstract: The invention concerns a method of transmitting video data comprising information bits (201), a video processing unit (10, 20, 40) with a control unit (12, 22, 42) for sending and/or receiving such video data, and a computer program product for the execution of said method. The method comprises the application of a systematic channel encoding (202) on the information bits (201) of the video data and obtaining a sequence comprising the encoded information bits (203) and error correction bits (204, 403) of the information bits (201). For transmission to another video processing unit (10, 20, 40), the encoded information bits (203) and the error correction bits (204, 403) are inserted into a primary coded picture network abstraction layer (205, 401) and a redundant coded picture network abstraction layer (206, 402), respectively.Type: GrantFiled: April 28, 2006Date of Patent: November 29, 2011Assignee: Alcatel LucentInventor: Hang Nguyen

Patent number: 8068716Abstract: A recording apparatus for recording audio-visual (A/V) contents directly from an A/V input source to a portable media player (PMP) is disclosed. The recorded A/V contents can be played back by the portable media player immediately upon stopping the recording. The recording apparatus does not involve the use of any intermediate computing or storage device other than the portable media player and the recording apparatus itself. The A/V contents for recording may come in the form of analog/digital signals or as digital data in compressed or uncompressed form from transmission and/or storage devices. Depending upon the nature of the input, the recording apparatus digitizes, encodes and/or transcodes the A/V contents and stores the processed A/V contents directly into the portable media player in playback ready format. The recording apparatus includes a one-button control interface for starting and stopping the recording of A/V contents to the portable media player.Type: GrantFiled: April 10, 2006Date of Patent: November 29, 2011Assignee: Streaming Networks (PVT.)

Patent number: RE43339Abstract: An audio and video recording and reproduction apparatus and method is described, which uses a movable storage memory such as a memory card, so that audio and video signals are easily accessed without separate editing devices. The apparatus uses a separable memory so that a deck is unnecessary, allowing small, lightweight constructions, and a compression algorithm results in longer playing time, while read/write operations robust to noise are achieved. Also, data desired by the user is easily accessible, and applications as a substitute for magnetic or disk media are also possible.Type: GrantFiled: March 8, 2004Date of Patent: May 1, 2012Assignee: LG Electronics Inc.Inventors: Se Yong Ro, Han Jung
