An MPEG object is an object-oriented data structure that may be used in the creation of interactive MPEG video stream. The MPEG object data structure includes an MPEG object interface defining data received by the MPEG object and data output by the MPEG object. The MPEG object data structure further includes either one or more MPEG video elements or an association to one or more MPEG video elements. The MPEG video elements are preferably defined as MPEG slices that include a plurality of encoded macroblocks. Additionally, the data structure may provide a method for receiving input through the MPEG object interface and in response to input from the client device outputting an MPEG video element. In certain configurations, the MPEG object contains a method that maintains state data for the MPEG object. The state data may be used to select between a plurality of MPEG elements to output. In other configurations, the MPEG object includes a method that provides for the control of streaming MPEG content from a source external to the MPEG object.

MPEG objects and systems and methods for using MPEG objects

A system and method are provided for processing video content, associated with a source image, for display on a television. The source image, such as a web page, and its associated (e.g., linked) video content are retrieved and separately encoded. The encoded source image and the encoded video content are composited together to form a sequence of encoded video frames, where a frame type of the video content is used to determine a type of a composited frame. For example, if all displayed frames of the video content are MPEG I-frames, then the composited frame also may be an I-frame. However, if any displayed frame of video content is an MPEG P-frame or B-frame, then the composited frame may be a P-frame.

System and method for providing video content associated with a source image to a television in a communication network

A system for creating composite encoded video from two or more encoded video sources in the encoded domain. In response to user input, a markup language-based graphical layout is retrieved. The graphical layout includes frame locations within a composite frame for at least a first encoded source and a second encoded source. The system either retrieves or receives the first and second encoded sources. The sources include block-based transform encoded data. The system also includes a stitcher module for stitching together the first encoded source and the second encoded source according to the frame locations of the graphical layout to form an encoded frame. The system outputs an encoded video stream that is transmitted to a client device associated with the user. In response to further user input, the system updates the state of an object model and replaces all or a portion of one or more frames of the encoded video stream. The system may be used with MPEG encoded video.

Interactive encoded content system including object models for viewing on a remote device

A method for regulating bandwidth usage in an output data stream transmitted on an analog channel from a cable head end. The output data stream comprises a plurality of input information content signals. For each input information content signal, a series of images are captured, compressed and formed into an input digital data stream. The bandwidth of each input digital data stream is regulated by associating the stream with a current bit allocation total. During each frame time: a bit allocation increment is added to the current bit allocation total for each input digital data stream. When a data packet to be transmitted for an input digital data stream is received by the multiplexer, the data packet is stored. When the number of bits in the stored data packet is not more than the current bit allocation total for the input digital data stream, the multiplexer forwards the stored data packet for transmission in the output data stream on the analog channel and decrements the current bit allocation total for the given input digital data stream by the number of bits in the stored data packet. In this way, no individual input channel takes more than its share of the bandwidth on the output stream on the analog channel.

Method for bandwidth regulation on a cable television system channel

A scrolling encoder encodes scrolling elements that are to be scrolled around all or a subset of the frames of a video stream or file with their movement in time and space controlled by a path to produce a video stream or file, without searching previous or subsequent frames of the video stream or file for reference blocks. The scrolling element can be an image, video, text or any combination thereof. The scrolling element is encoded using information about the contents of the scrolling element and information about a path the scrolling element is to take across a screen. The information about the contents of the scrolling element is obtained when the scrolling element is first introduced into a frame. The information about the path of the scrolling element is provided by an external component or is otherwise deduced. Optionally, the path information includes information about how the scrolling element is to change appearance. This information may be used to automatically generate error terms.

System and method for encoding scrolling raster images

A system and method for providing video content associated with a source image to a television that is part of a communication network is provided. At least a portion of the source image and the video content are displayed on the television. A request at a content distribution platform in the communication network is received for display of the source image from a communication device associated with the television. In certain embodiments, the communication network is cable television network. In other embodiments, the communication network may be a television over IP network. The requested source image is retrieved by the content distribution platform. The source image is displayed on a user's television, and the user may desire to have video content associated with a link displayed on the user's television. A request for video content associated with the link is then received. The content distribution platform then retrieves the video content that is associated with the link. The video content is pre-encoded and may be, for example, an MPEG data file. The content distribution platform then composites the video content and at least a portion of the source image together. The data of the source image and the pre-encoded video content form a video stream that can be decoded by a decoder associated with the television. The composited video stream is then sent through the communication network to the communication device where it is decoded and displayed on the user's television. In certain embodiments, the source image is a web page.
