Patent number: 10027962Abstract: 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.Type: GrantFiled: July 11, 2016Date of Patent: July 17, 2018Assignee: AT&T INTELLECTUAL PROPERTY II, L.P.Inventors: Barin Geoffry Haskell, Atul Puri, Robert Lewis Schmidt

Publication number: 20170295367Abstract: 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.Type: ApplicationFiled: June 26, 2017Publication date: October 12, 2017Inventors: BARIN GEOFFRY HASKELL, Atul Puri, Robert Lewis Schmidt

Patent number: 9641897Abstract: 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.Type: GrantFiled: September 14, 2012Date of Patent: May 2, 2017Assignee: AT&T Intellectual Property II, L.P.Inventors: Barin Geoffry Haskell, Atul Puri, Robert Lewis Schmidt

Patent number: 9635376Abstract: 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.Type: GrantFiled: May 12, 2015Date of Patent: April 25, 2017Assignee: AT&T Intellectual Property II, L.P.Inventors: Barin Geoffry Haskell, Atul Puri, Robert Lewis Schmidt

Patent number: 9420309Abstract: A video coding system that codes video objects as scalable video object layers. Data of each video object may be segregated in to 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 simple decoder may decode only the base layer of the 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 object.Type: GrantFiled: August 29, 2014Date of Patent: August 16, 2016Assignee: AT&T Intellectual Property II, L.P.Inventors: Barin Geoffry Haskell, Atul Puri, Robert Lewis Schmidt

Patent number: 8621532Abstract: Video-coded information is transmitted over a network at a priority level that is determined based on feedback from the network. In an embodiment, the feedback comprises a response to a request for information on whether the network currently has the available capacity to transmit additional high priority traffic. In an embodiment, a candidate base layer frame is transmitted over a network as a base layer frame if permission to send high priority data was granted and is transmitted over the network as an enhancement layer frame if permission to send high priority data was denied. In a further embodiment, the candidate base layer frame is deleted if permission to send high priority data was denied.Type: GrantFiled: May 23, 2006Date of Patent: December 31, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Baldine-Brunel Paul, Glenn L.
