Patent number: 11621880Abstract: Systems and methods are described herein for inserting supplemental content into a QAM signal. A unicast QAM signal between a server and a client device for delivery of content is established. The QAM signal has a particular frequency corresponding to the channel on which it will be transmitted to the client device. A request or other signal may be received from the client device requesting that supplemental content be inserted into the QAM signal. A portion of the bandwidth of the QAM signal is allocated for the supplemental content. The supplemental content is transcoded into a supplemental QAM signal in the particular frequency. The supplemental content may be packetized content such as internet protocol-based content and may be retrieved from a server or database. The supplemental QAM signal is then inserted into the unicast QAM signal using the allocated portion of the bandwidth.Type: GrantFiled: March 8, 2022Date of Patent: April 4, 2023Assignee: Rovi Guides, Inc.Inventors: Michael McCarty, Glen E.

Patent number: 8209730Abstract: A method of transmitting a Video-on-Demand (VOD) program involves at a service provider head-end, separating VOD program data into first and second parts; transmitting the first part over a communication network to a recipient receiver for storage at a storage device as cached speculative data, where the transmitting is carried out as a data push when the communication network has available bandwidth to permit such transmitting and without regard for any order having been received for the VOD program to be sent to the receiver; receiving an order for the VOD program to be sent to the receiver; and streaming the second part to the receiver for reassembly into the VOD program at the receiver by combining the second part as it is streamed with the cached speculative data. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: GrantFiled: June 22, 2009Date of Patent: June 26, 2012Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Robert L. Hardacker, Keith Resch, Robert Allan Unger

Patent number: 8208067Abstract: A method includes receiving a digital video segment simulating motion at one speed, the frames in the segment spaced at a uniform time interval. The method further includes receiving a desired speed of motion, determining the appropriate uniform time interval corresponding to the desired speed, and generating a frame sequence simulating the motion at the desired speed, the frames in the generated sequence spaced at the determined appropriate uniform time interval. If the generated frame sequence includes a frame from the original segment, then only frames from the original segment are included in the generated frame sequence, and if the generated frame sequence includes an interpolated frame then only interpolated frames are included in the generated frame sequence.Type: GrantFiled: July 11, 2007Date of Patent: June 26, 2012Assignee: Adobe Systems IncorporatedInventors: Harshdeep Singh, Samreen Dhillon

Patent number: 8195024Abstract: There is provided stream generating apparatus which generates a multiplexed stream including moving picture data. The apparatus includes a moving picture encoding processing section for generating a moving picture stream by encoding the moving picture data allowing switching between a reference frame rate and more than one frame rate different from the reference frame rate according to a desired timing; a time control information generating section for generating playback time control information with certain intervals corresponding to picture frame display cycles relevant to the reference frame rate, for each picture frame inputted to the moving picture encoding processing section; and a multiplexing processing section for generating the multiplexed stream by multiplexing the moving picture stream and the playback time control information.Type: GrantFiled: May 15, 2007Date of Patent: June 5, 2012Assignee: Sony CorporationInventor: Takayuki Sato

Patent number: 8184959Abstract: An apparatus and method for recording/playing a moving picture in a digital broadcast receiver is disclosed, which supports a trick mode. If digital broadcasting is recorded, the digital broadcasting is converted into a video sequence having a new format and frame type, such as an I frame structure, and then recorded in a recording medium. Also, corresponding I frame is directly uploaded and played in accordance with times speed of trick play using the frame index of video data recorded after being converted into the I frame. Thus, it is possible to normally provide more elaborate moving picture trick play for every times speed.Type: GrantFiled: January 31, 2006Date of Patent: May 22, 2012Assignee: LG Electronics Inc.Inventor: Jin Seok Im

Patent number: 8135264Abstract: A multimedia visual progress indication system that provides a cache bar that is overlaid onto the program material or displayed on a dedicated display. A cache bar indicates the length of a recording session or the length of stored program material and expands to the right when material is being recorded. Index and/or bookmark indicators are displayed next to the cache bar. A position indicator moves within the cache bar and tells the user visually where his current position is within the program material. Numeric time or counter mark of the current position is displayed in the vicinity of the cache bar. The trick play bar and its associated components are displayed for a predetermined time period.Type: GrantFiled: March 4, 2008Date of Patent: March 13, 2012Assignee: TiVo Inc.Inventors: Robert Vallone, Howard Look, Ain McKendrick

Patent number: 8116609Abstract: A method for traversing a multiplexed data packet stream including choosing a starting location in a multiplexed data packet stream; making a bi-directional search from the starting location to locate a nearest system stream object; and traversing the system stream as a doubly-linked list of objects. Traversing the system stream preferably includes traversing object links of the doubly-linked list of objects. The objects are further preferably cached with an LRU process. Multiple disjoint locations in the system stream can be accessed with a virtual linked list. The virtual linked list can be used to search forwardly; backwardly, or both forwardly and backwardly.Type: GrantFiled: July 29, 2006Date of Patent: February 14, 2012Assignee: 658276 N.B. Ltd.Inventor: Michael L. Gough
