摘要： A quantizer and dequantizer for use in a video coding system that applies non linear, piece-wise linear scaling functions to video information signals based on a value of a variable quantization parameter. The quantizer and dequantizer apply different non linear, piece-wise linear scaling functions to a DC luminance signal, a DC chrominance signal and an AC chrominance signal. A code for reporting updates of the value of the quantization parameter is interpreted to require larger changes when the quantization parameter initially is large and smaller changes when the quantization parameter initially is small.

摘要： A predictive video coder performs gradient prediction based on previous blocks of image data. For a new block of image data, the prediction determines a horizontal gradient and a vertical gradient from a block diagonally above the new block (vertically above a previous horizontally adjacent block). Based on these gradients, the encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block. The encoder determines a residual that is transmitted in an output bitstream. The decoder performs the identical gradient prediction and predicts image information without need for overhead information. The decoder computes the actual information based on the predicted information and the residual from the bitstream.

摘要： A method and apparatus prioritizing video information during coding and decoding. Video information is received and an element of the video information, such as a visual object, video object layer, video object plane or keyregion, is identified. A priority is assigned to the identified element and the video information is encoded into a bitstream, such as a visual bitstream encoded using the MPEG-4 standard, including an indication of the priority of the element. The priority information can then be used when decoding the bitstream to reconstruct the video information.

摘要： A number of novel configurations for MPEG-4 playback, browsing and user interaction are disclosed. MPEG-4 playback systems are not simple extensions of MPEG-2 playback systems, but, due to object based nature of MPEG-4, present new opportunities and challenges in synchronized management of independent coded objects as well as scene composition and presentation. Therefore, these configurations allow significantly new and enhanced multimedia services and systems. In addition, MPEG-4 aims for an advanced functionality, called Adaptive Audio Visual Session (AAVS) or MPEG-J. Adaptive Audio Visual Session (AAVS) (i.e., MPEG-AAVS, MPEG-Java or MPEG-J) requires, in addition to the definition of configurations, a definition of an application programming interface (API) and its organization into Java packages. Also disclosed are concepts leading to definition of such a framework.

摘要： A video coding system that codes video objects as scalable video object layers. Data of each video object may be segregated into one or more layers. A base layer contains sufficient information to decode a basic representation of the video object. Enhancement layers contain supplementary data regarding the video object that, if decoded, enhance the basic representation obtained from the base layer. The present invention thus provides a coding scheme suitable for use with decoders of varying processing power. A single decoder may decode only the base layer of video objects to obtain the basic representation. However, more powerful decoders may decode the base layer data of video objects and additional enhancement layer data to obtain improved decoded output. The coding scheme supports enhancement of both the spatial resolution and the temporal resolution of video objects.

摘要： File formats systems and methods are disclosed that provide a framework that integrates concepts, such as objects based audio-visual representation, meta-data and object oriented programming, to achieve a flexible and generic representation of the audiovisual information and the associated methods to operate on the audiovisual information. A system and method are disclosed for storing data processed from presentation data. The data is stored according to a method comprising coding input presentation data by identifying objects from within the presentation data, coding each object individually and organizing the coded data into access layer data units. The access layer data units are stored throughout a plurality of segments, each segment comprising a segment table in a header portion thereof and those access layer data units that are members of the respective segment, there being one entry in the segment table for each access layer data unit therein. A plurality of extended segments are also stored, each of the extended segments further comprising one or more of the access layer data units that include protocol specific data, the extended segments each represented by a extended segment header. The data of an accessible object is also stored, including an accessible object header and identifiers of the plurality of extended segments, each of the extended segments being a member of the same object.
