Patent number: 8145035Abstract: When reading an AV Clip which is formed by multiplexing a plurality of elementary streams from a BD-ROM and playing back the AV Clip, an STN_table that lists an entry of each elementary stream is acquired from PlayList information on the BD-ROM. For each elementary stream shown in the STN_table, a judgment is made as to whether the elementary stream satisfies a predetermined condition. Of all elementary streams judged as satisfying the predetermined condition, an elementary stream having a highest entry in the STN_table is selected and played back.Type: GrantFiled: June 17, 2004Date of Patent: March 27, 2012Assignee: Panasonic CorporationInventors: Wataru Ikeda, Tomoyuki Okada, Yasushi Uesaka

Patent number: 8131133Abstract: A system and method are disclosed for modifying a television broadcast signal. In one embodiment, the system includes a memory that stores an alternate commercial signal, and a controller that is coupled to the memory and receives the broadcast signal. The broadcast signal includes a program signal and commercial signals. The controller substitutes the alternate commercial signal for one of the commercial signals upon determining that a first condition has been met, for example, upon the sensing two video/audio blank periods in the broadcast signal separated by a predetermined time period. In another embodiment, a broadcast signal including a series of screen signals alternating with a series of blanking signals is embedded, at an upstream location, with additional information relating to alternate commercials or commands during the blanking signals. At a downstream location, a controller processes the additional information and modifies the broadcast signal in response.Type: GrantFiled: April 16, 2002Date of Patent: March 6, 2012Inventor: David A.

Publication number: 20110116764Abstract: A method, system, apparatus, article of manufacture, and computer program product provide the ability to non-destructively generate a file based master. A domestic source (having domestic audio and video content) with textless content (have portions of the domestic source that is devoid of text) is obtained. A localized source (e.g., localized audio-video) based on the domestic source is received. The localized video is compared to the domestic source to determine differences. The localized video is bladed and realigned with the domestic source. Metadata (of the differences) is transposed onto the domestic source. Texted portions in the domestic source are obscured with corresponding portions of the textless content. Texted material (based on the localized video and texted portions) is created. The localized video content and the textless content are discarded.Type: ApplicationFiled: November 16, 2010Publication date: May 19, 2011Applicant: Twentieth Century Fox Film CorporationInventors: Arjun Ramamurthy, Geoffrey A.

Patent number: 7912349Abstract: The operation of a video playback application supporting display of an encoded video may be validated using a special-purpose video decoder. The decoder compares pre-determined indications of dependency frames for frames of the video with dependency frames that are identified based on an order in which the frames are provided to the decoder. Based on the comparison, the decoder verifies that the frames may be decoded with correct dependencies. In one implementation, a frame of a video is accessed. A first description and a second description identifying frames of the video upon which decoding of the accessed frame depends are accessed. The first description is compared to the second description, and whether the first and second descriptions identify a common set of frames is determined based on the identifying.Type: GrantFiled: April 25, 2005Date of Patent: March 22, 2011Assignee: Apple Inc.Inventors: John Samuel Bushell, Christopher Lance Flick

Publication number: 20110052147Abstract: The invention relates playing back video with subtitles. A playback apparatus (20) is provided for playback of video data (e.g. in DivX-format) and corresponding subtitle data files from a record carrier. The one or more subtitle data files may be stored on the carrier without language metadata of the subtitles. The apparatus comprises units operable to access the one or more subtitle data files on the associated record carrier, fetch a content sample (21-26) of the subtitle data files, and output to a display unit (3) a signal representing the fetched content samples. The user may then select one of the content samples and thus identify the desired subtitle file to be reproduced.Type: ApplicationFiled: October 22, 2007Publication date: March 3, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Jagadish Murugan, Sunil Sridhara, Narendranath Udupa

Patent number: 7894709Abstract: A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. A best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output.Type: GrantFiled: August 4, 2004Date of Patent: February 22, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Mauro Barbieri
