20100329348 | Method and Apparatus for Accomplishing Multiple Description Coding for Video - A method and apparatus for utilizing temporal prediction and motion compensated prediction to accomplish multiple description video coding is disclosed. An encoder receives a sequence of video frames and divides each frame into non-overlapping macromacroblocks. Each macromacroblock is then encoded using either an intraframe mode (I-mode) or a prediction mode (P-mode) technique. Both the I-mode and the P-mode encoding techniques produce an output for each of n channels used to transmit the encoded video data to a decoder. | 12-30-2010 |

20140348225 | METHOD AND APPARATUS FOR MULTIPLE DESCRIPTION VIDEO CODING - An encoder includes a controller to determine whether macroblocks of a frame of video content are to be processed by intra-frame encoding or by predictive coding. The encoder includes a switch coupled to the controller. The encoder includes an intra-frame unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by intra-frame encoding. The encoder includes a predictive unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by predictive encoding. The encoder also includes a redundancy allocation unit coupled to the controller. The controller determines whether to process the macroblocks by intra-frame encoding or predictive frame encoding based on information received from the redundancy allocation unit. | 11-27-2014 |

20130142451 | METHOD AND APPARATUS FOR EVALUATING QUALITY ESTIMATORS - A system that incorporates teachings of the present disclosure may include, for example, distorting a seed image to generate first and second images where the distortions cause the first and second images to have a potential false tie according to a target quality estimator and generating a third image from the first and second images where the third image is generated based on a proxy quality estimator so that the third image has a potential false ordering according to the target quality estimator. Other embodiments are disclosed. | 06-06-2013 |
20150078670 | METHOD AND APPARATUS FOR GENERATING QUALITY ESTIMATORS - A system that incorporates teachings of the present disclosure may include, for example, sampling a variable effect distribution of viewing preference data to determine a first set of effects comprising a plurality of first distortion type effects associated with a first distortion type of a first image and to determine a second set of effects comprising a plurality of second distortion type effects associated with the second distortion type of a second image, calculating a preference estimate from a logistic regression model of the viewing preference data according to the first set of effects and the second set of effects, wherein the preference estimate comprises a probability that the first image is preferred over the second image, and selecting one of the first distortion type or the second distortion type according to the preference estimate. Other embodiments are disclosed. | 03-19-2015 |

20110103484 | Scalable Video Encoder/Decoder with Drift Control - A system, method and computer-readable media are introduced that relate to data coding and decoding. A computing device encodes received data such as video data into a base layer of compressed video and an enhancement layer of compressed video. The computing device controls drift introduced into the base layer of the compressed video. The computing device, such as a scalable video coder, allows drift by predicting the base layer from the enhancement layer information. The amount of drift is managed to improve overall compression efficiency. | 05-05-2011 |

20100054340 | METHODS AND APPARATUS TO DETECT TRANSPORT FAULTS IN MEDIA PRESENTATION SYSTEMS - Example methods and apparatus to detect transport faults in media presentation systems are disclosed. An example method comprises decoding a media stream to form audio data and pixel data, computing a first value representative of the media stream using pixel data associated with a first set of the video frames, computing a second value representative of the media stream using pixel data associated with a second set of the video frames, computing a third value representative of first speech in a first segment of the audio data, computing a fourth value representative of second speech in a second segment of the audio data, determining a fifth value representative of a likelihood that a transport failure has affected the media stream, the fifth value determined using the first, second, third and fourth values, and comparing the fifth value to a threshold to determine whether to generate a transport failure alert. | 03-04-2010 |
20110085744 | No-Reference Spatial Aliasing Measure for Digital Image Resizing - A method for detecting aliasing artifacts includes receiving a second image that has been converted from a first image and evaluating the second image using a computer to detect aliasing artifacts due to the conversion, where the evaluation is performed without reference to the first image. The second image is a different size than the first image The second image is evaluated by identifying patches in the image that are likely to contain strong directional energy with few distractions and to estimate a direction component for each of the identified patches. The total energy of each patch is partitioned into an estimated signal energy and an estimated aliasing energy. The estimated aliasing energy and the estimated signal energy of each of the identified patches are combined to obtain an estimate of the aliasing artifacts in the image. | 04-14-2011 |
20130156342 | No-Reference Spatial Aliasing Measure for Digital Image Resizing - A method includes identifying an area in an image that is associated with strong directional energy. The method further includes determining a first estimate of signal energy for the area and a second estimate of aliasing energy for the area. The method further includes estimating a severity of an aliasing error of the image based on the first estimate and the second estimate. | 06-20-2013 |
