20150244999 | IMAGE PROCESSING APPARATUS THAT DEVELOPS PHOTOGRAPHED DATA, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM - An image processing apparatus which is capable of satisfactorily developing photographed data by making up a difference in saturation level between color signals through replacement of a color signal. Saturation levels of respective color signals in photographed data are calculated, and an upper limit of a dynamic range in the photographed data is determined. Based on the upper limit, replacement ratios for the color signals, which change toward the saturation levels of the color signals, are obtained. Each of the color signals is adjusted according to the upper limit. Based on the replacement ratios, a replacement process is carried out in which a color signal of which the saturation level is low is replaced with a color signal of which the saturation level is high. The photographed data on which the replacement process has been carried out is subjected to a predetermined process to obtain developed data. | 2015-08-27 |

Saturation levels of color signals of three colors are calculated on photographed data. Color signal values in each pixel of the photographed data are acquired as pixel information. If it is determined, based on the saturation levels and the pixel information, to perform substitution, substitution for a color signal having the second highest saturation level is performed according to a color signal having the highest saturation level, and substitution for a color signal having the lowest saturation level is performed according to the color signals having the highest and second highest saturation levels. Predetermined processing is performed on photographed data on which substitution processing has been performed to thereby generate the developed data. | 2015-08-27 |

The method includes the steps of predictively identifying for pre-buffering at least one audio/video stream pair that may be selected for playback by a user subsequent to a currently playing audio/video stream pair, computing a first rate for pre-buffering an audio portion of the at least one audio/video stream pair and a second rate for pre-buffering a video portion of the at least one audio/video stream pair, downloading the audio portion at the first rate and downloading the video portion at the second rate, and storing the downloaded audio portion and the downloaded video portion in a content buffer. | 2015-08-27 |
20150245094 | Merging Content Channels - A method for merging content channels is disclosed. The method includes identifying, by a processing device, target channels to merge into a result channel, wherein the result channel is formed in view of at least one set of users of the target channels viewing at least one of a same set or a similar set of content items from the target channels. The method further includes subscribing, by the processing device, the users of the target channels to the result channel and associating, by the processing device, the set of the content items of the target channels with the result channel. | 2015-08-27 |
20150245095 | SYSTEMS AND METHODS FOR NOTIFYING A USER WHEN ACTIVITY EXCEEDS AN AUTHORIZATION LEVEL - Systems and methods for generating a notification when activity exceeds an authorization level are provided. A determination is made as to whether content currently being presented to a first user exceeds an authorization level associated with the first user. In response to determining that the content exceeds the authorization level, the content being presented is monitored to determine whether the content meets a criterion. An amount of time the content being presented meets the criterion is measured. In response to determining that the amount of time exceeds a threshold, a communication is transmitted to a second user indicating that the content currently being presented to the first user exceeds the authorization level. | 2015-08-27 |

20150245097 | TIMESTAMPED COMMENTARY SYSTEM FOR VIDEO CONTENT - A video commentary system receives video content items from users in a community. Such video content items are presented to viewers in the community. The system presents submission controls through which the viewers can submit feedback related to specific time points within that presentation. The controls can be used to submit textual, video, or audio comments. The controls can include labeled buttons that viewers can activate to submit categorized comments. Each submission is associated with a timestamp corresponding to the current video frame. The user interface includes regions that display, in real-time, the submissions received from the viewers. Submissions can indicate their timestamps. A bar graph indicates, by category and by time interval, quantities of categorized comments that have been received relating to various time intervals in the presentation. | 2015-08-27 |
20150245098 | METHODS, APPARATUS, AND USER INTERFACES FOR SOCIAL USER QUANTIFICATION - In an embodiment, an IPTV system provides social user quantifications by maintaining a user profile for a user that identifies a plurality of actions of the user with a respective plurality of video assets provided by the IPTV system. Each of the plurality of actions indicates that the user viewed, downloaded, recorded, scheduled to record, or rated the respective video asset. The IPTV system determines a social quantification value for the user based upon one or both of, the plurality of actions of the user within the IPTV system, and an additional plurality of actions by a plurality of other users of the IPTV system. The IPTV system causes an IPTV user interface to be presented to the user on a display of an electronic device that comprises a quantified self UI element that is based upon the social quantification value. | 2015-08-27 |
