20110002391 | DIGITAL IMAGE COMPRESSION BY RESOLUTION-ADAPTIVE MACROBLOCK CODING - Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” If appropriate, a macroblock is “downsampled” to a lower resolution. The lower-resolution macroblock is then encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted and actual contents of the macroblock. The low-resolution residual is then either transmitted to an image decoder or stored for later use. In some embodiments, the encoder calculates the rate-distortion costs of encoding the original-resolution macroblock and the lower-resolution macroblock and then only encodes the lower-resolution macroblock if its cost is lower. When a decoder receives a lower-resolution residual, it recovers the lower-resolution macroblock using standard prediction techniques. Then, the macroblock is “upsampled” to its original resolution by interpolating the values left out by the encoder. The macroblocks are then joined to form the original digital image. | 01-06-2011 |
20110002554 | DIGITAL IMAGE COMPRESSION BY RESIDUAL DECIMATION - Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” Each macroblock is encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted content of the macroblock and the actual content of the macroblock. The residual is then “decimated” by taking an orderly subset of its values. The decimated residual is then either transmitted to an image decoder or is stored for later use. To recreate the original image, the macroblocks are first recreated from their received residuals. When a decimated residual is received, the values of the residual left out during decimation are interpolated from the values actually received. Using the prediction techniques along with the residual, the original content of the macroblock is recovered. The macroblocks are then joined to form the original digital image. | 01-06-2011 |

20130124664 | COORDINATING MEDIA PRESENTATIONS AMONG PEER DEVICES - A group of “servant” devices each downloads a media presentation and renders the presentation to a local user. However, a “master” device directs the servants as to which chunks to download and when to render the presentation. In this way, the master keeps the presentations on the separate servants in synchrony. The master uses status information from the servants to coordinate the downloads. If, for example, one servant is having a difficult time keeping up with the presentation, then the master may choose to direct that servant to download a reduced-resolution version of the presentation (which requires less bandwidth to download). If the user of one of the servant devices enters a playback command, then that command is not executed locally but is instead sent to the master device which in turn sends the command to all of the servants so that they may execute the playback command in synchrony. | 05-16-2013 |
20130125188 | MULTIMEDIA PRESENTATION PROCESSING - Disclosed are methods and apparatus for generating or selecting bookmarks for a multimedia presentation. These bookmarks may be encoded with the multimedia presentation into a multimedia container, which may then be transmitted to an end-user device. Also, these bookmarks may be made available to an end-user device over the Internet. Each bookmark may demarcate a content event and may comprise semantic information for that content event. Bookmarks may be generated automatically (e.g., by performing a media-analysis process) reviewed by a human. The end-user device may use the bookmarks to perform a trick play (e.g., semantic trick play) on the multimedia presentation. | 05-16-2013 |
20130132521 | PRESENTING ALTERNATIVE MEDIA CONTENT BASED ON ENVIRONMENTAL FACTORS - The environment surrounding an end-user device is analyzed. When a user of the device requests a download of a media presentation, the device uses the results of the environmental analysis to automatically request an alternative audio or video track for the media presentation. By choosing a better alternative before the download even begins, the device avoids user frustration and conserves resources. For example, a user requests a music video to be played on his mobile phone. By using its microphone, the phone analyzes its current audio environment and concludes that there is considerable background noise. Then when requesting a download of the music video, the phone requests an “enhanced-clarity” soundtrack to increase the odds that its user will be able to hear the music over the background noise. In some situations, the alternative track is rendered in addition to, rather than instead of, the default tracks of the media presentation. | 05-23-2013 |
20130144725 | PRESENTING CONTENT TO A USER IN ACCORDANCE WITH AN AGREED UPON CONTENT-PRESENTATION POLICY - Systems and methods are provided for presenting content to a user.

20140270504 | LOGO PRESENCE DETECTION BASED ON BLENDING CHARACTERISTICS - A video processing system detects an overlay image, such as a logo, in a picture of a video stream, the overlay for example being a broadcaster's logo. The detection is based on evaluation of blending characteristics of a picture frame. The method of detection of an overlay defines first and second areas within the image, the first and second areas being non-overlapping. Next an alpha-blended value is calculated for the mean color value of the second area with an overlay color value. Then, if the mean color value of the first area is closer to the alpha-blended value than it is to the mean color value of the second area, the overlay can be indicated as detected and defined within the picture. Detection of the overlay can be used to identify an owner of the video, or detect when a scene change such as a commercial occurs. | 09-18-2014 |
