20200413041 | METHOD FOR IMPROVED INTRA PREDICTION WHEN REFERENCE SAMPLES ARE MISSING - The method for intra frame prediction allows for the recovery of some intra directional modes that are otherwise rendered useless due to the classical padding process. Directional modes are recovered by filling pixel locations in the prediction unit with samples from the portion of the unit that is determined to have samples available for use using a counterpart directional mode to the one that is useless. When it is determined that reference samples are missing for a particular prediction unit or portion thereof given a particular directional mode, a determination is made about whether reference samples along another portion of the prediction unit are available. The other portion is the side of the prediction unit at an opposite end of the particular directional mode. When it is determined that such reference samples are available, it is possible to extend the number of intra directional modes by replacing the particular directional modes that are rendered useless, because of the unavailability of reference samples, with their counterpart directional modes that are oppositely directed. | 2020-12-31 |

Through this solution, live streaming content is provided to a user by live streaming, and an emotion of the user when the user is watching the live streaming content is perceived to interact with the user, to combine a live streaming technology with a perception technology, and according to the emotion of the user while watching the content, adjust the content watched by the user without delay, thereby achieving effective interaction between a content provider and a content viewer. | 2020-12-31 |
20200413136 | Method and Apparatus for Content Control Based on the Number of Viewers - Disclosed herein are methods and system for content control based on the number of viewers and views. The method may include obtaining, by an audience determination device, a number of viewers watching a selected content being played on a display device. A content receiving device may determine if a determined number of viewers exceeds a purchased number of viewers. If the determined number of viewers exceeds the purchased number of viewers, then the playing of the selected content is paused. An error message may be provided so that corrective action may be taken. The playback of the selected content may be resumed when the determined number of viewers does not exceed the purchased number of viewers. In an implementation, the content receiving device may also determine if there any available purchased views for the selected content. | 2020-12-31 |
20200413137 | ADVERTISEMENT GENERATION BASED ON A USER IMAGE - A method includes receiving, at a computing device, first image data of a viewer of an output of user equipment. The method includes selecting, at the computing device based on a first item identified in the first image data, a background component to be included in multimedia content. The method also includes providing, from the computing device, the multimedia content to the user equipment for presentation to the viewer. The multimedia content includes the background component and a first foreground component, where the first foreground component has a first characteristic. | 2020-12-31 |
20200413138 | Adaptive Media Playback Based on User Behavior - Media playback may be controlled or adapted using behavioral player adaptation. The user and the user's physical environment are monitored via sensors. Sensor data representative of relevant user behavior and physical properties of the environment where the user is located is collected, aggregated, and pre-processed to determine the state of parameters of the sensed environment that may be relevant. The pre-processed sensor data is examined to determine the state of user model parameters. Machine learning may be used for the data examination; a neural network is used to learn the key parameters from the pre-processed data that then are used for media playback adaptation and/or control. | 2020-12-31 |

20200413140 | METHOD AND APPARATUS FOR RECORDING ADVERTISED MEDIA CONTENT - Aspects of the subject disclosure may include, for example, obtaining social network information associated with a first user, wherein the social network information includes information identifying a second user who is related to the first user. A determination is made that the first user had selected, during a presentation of a first media content item by a first media processing device of the first user, recording of a second media content item that had been advertised during the presentation of the first media content item. Responsive to the determining that the first user had selected the recording of the second media content item, a second media processing device of the second user is directed to record the second media content item. Other embodiments are disclosed. | 2020-12-31 |
