In a method of enhancing a viewer's experience of a video program, a plurality of selectable alternative video program scenes are provided for a video program being viewed on a display. The selectable alternative program versions are pre-rendered video scenes. A user is prompted to select at least one of the selectable alternative video program scenes for viewing.

The disclosure relates to generating haptic feedback based on video content analysis, sensor information that includes one or more measurements of motion of one or more objects on a video, and / or sensor information that includes one or more measurements of motion of one or more image capture devices. The video content analysis may include image processing of the video. The system may identify one or more events based on the image processing and cause a haptic feedback based on the one or more events. The haptic feedback may vary based on an estimated acceleration of an object of a scene of the video, wherein the estimated acceleration is based on the image processing. The estimated acceleration may be made more accurate at high speeds using the sensor information and an estimated acceleration based on the sensor information may be made more accurate at lower speeds based on the image processing.

The invention discloses a method for controlling the rotation of a camera. The method comprises: during a video communication process, identity characteristic information of a communication user is obtained; according to the identity feature information, a rotating speed of a camera matching the communication user is determined; a set number of face images, captured by the camera within a set timeinterval, of the communication user are obtained; if the face rotation frequency, determined by adjacent face images among the set number of face images, of the communication user within the set timeinterval does not exceed a frequency threshold, a first face image and a last face image among the face images captured within the set time interval are obtained; according to the first face image and the last face image, a face rotation parameter is determined; and on the basis of the rotating speed and the face rotation parameter, the camera is controlled to make rotation. Therefore, the personalized need of the user during the video communication process can be met; the video experience of the user is improved; and a phenomenon that the user at the other side in video communication feels uncomfortable because of frequent rotation of the face of the user at one side is avoided.

A built-in video conference cooperative operation system comprises a multi-point control unit and a plurality of video conference terminal units; in each video conference, only one video conference terminal unit is used as a cooperative operation server and other video conference terminal units are cooperative operation client terminals; furthermore, only one cooperative operation client terminalhas a remote operative authority simultaneously. The cooperative operation client terminal with the remote operation authority collects the control information of a keyboard and a Mouse, encodes the information and transmits the encoded information to the cooperative operation server by the multi-point control unit; the cooperative operation server receives and decodes the control information of the keyboard and the Mouse, thus obtaining the operation instruction of the Mouse and the keyboard executable by the computer. The system solves the problem that the computer screen stream of the existing video conference system can be watched only by a dual-stream function and the auxiliary-stream can not be used for cooperative operation, perfects the cooperative mode of the user for informationcommunication and improves working efficiency and quality.

The embodiment of the invention discloses a media information pushing method and device. The media information pushing method can comprise the following steps: receiving an information pushing request sent from a client side, and obtaining the characteristic information of a user according to user identification contained in the pushing request; comparing the attribute of each piece of media information with the characteristic information of the user to calculate the first matching value of each piece of media information, and confirming the media information of which the first matching value is greater than a preset value as media information to be analyzed; comparing the historical interaction data of the media information to be analyzed with the characteristic information of the user to calculate the second matching value of the media information to be analyzed, and confirming the media information of which the sum of the first matching value and the second matching value is highest as media information to be pushed; and pushing the media information to be pushed to the client side. By use of the media information pushing method and device, information pushing accuracy and information popularization effectiveness can be improved.
