20090187958 | METHOD AND APPARATUS FOR MANAGING VIDEO TRANSPORT - A method and apparatus for managing video transport is disclosed. A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to predict visibility to a viewer of packet loss impairment for communicated video content based at least in part on scene information for one or more packets of the video content. Other embodiments are disclosed. | 07-23-2009 |
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 |

20150134739 | METHOD AND APPARATUS FOR DISTRIBUTING CONTENT - Aspects of the subject disclosure may include, for example, receiving a plurality of media content instances, where each media content instance of the plurality of media content instances comprises origination information, identifying a common event from the origination information of each media content instance of the plurality of media content instances, determining a plurality of viewing perspectives of the plurality of media content instances responsive to identifying the common event, and sending an alert to a social network to enable access to a viewing perspective of the plurality of viewing perspectives. Other embodiments are disclosed. | 05-14-2015 |
20150149902 | MANIPULATION OF MEDIA CONTENT TO OVERCOME USER IMPAIRMENTS - A system, process and software that incorporate the subject disclosure may include, for example, identifying a condition that causes an impaired perception of an original media content item during a presentation. A media content modification is determined, wherein application of the media content modification to the original media content item results in a modified media content item. The modified media content item, when presented to the media presentation device, ameliorates the impaired perception of the media content item. The media content modification is applied to the original media content item resulting in the modified media content item. The modified media content item is presented at the media presentation device contemporaneously with the original media content item, allowing different viewers to observe the modified media content item simultaneously with the original. Other embodiments are disclosed. | 05-28-2015 |
20150150070 | METHOD AND APPARATUS FOR PROVIDING MEDIA CONTENT - A method that incorporates teachings of the subject disclosure may include, for example, receiving, by a system comprising a processor, first media content from a service provider network over a high resolution channel at a first resolution, determining whether a first resolution exceeds a resolution threshold for viewing the first media content, transmitting a notification to the service provider network that the first resolution exceeds the resolution threshold, receiving the first media content from the service provider network over the high resolution channel at a second resolution according to the notification, wherein a difference between the first resolution and the second resolution provides unused bandwidth on the high resolution channel, and receiving second media content from the service provider network over the unused bandwidth of the high resolution channel. Other embodiments are disclosed. | 05-28-2015 |
