In one aspect, a method includes determining a content-modification operation channel-change rate for a group of content-presentation devices having a common content-presentation device attribute; comparing the content-modification operation channel-change rate with a baseline channel-change rate; determining that a result of the comparing satisfies a threshold condition; and based on determining that the result of the comparing satisfies the threshold condition, preventing at least one content-presentation device of the group of content-presentation devices from carrying out a future content-modification operation.

Aspects of the subject disclosure may include, for example, a method that includes obtaining, by a processing system including a processor, video frames over a network; the processing system uses a machine learning algorithm to identify in each frame a first region comprising a natural image and a second region comprising a synthetic graphic image. The processing system separates the natural image from the synthetic graphic image to generate a natural video and a graphics video, encodes the natural video, and processes the graphics video to generate instructions for rendering graphic images at a client system. The client system performs a decoding procedure for the encoded video, a rendering procedure for client-side graphics in accordance with the instructions, and a compositing procedure to obtain a presentable video stream including the natural image and a client-side graphic corresponding to the synthetic graphic image. Other embodiments are disclosed.

Implementations disclose methods and systems for providing a media item at an adjusted playback. A method includes receiving, from a first user device, a playback request from a first user for a first media item including one or more portions of media content; determining an adjusted playback for at least one portion of the first media item that is different than a default playback for the at least one portion of the first media item. The determining is based on previous playback behavior of one or more users in relation to one or more media items that each included one or more portions of media content corresponding to the one or more portions media content of the first media item; and causing the at least one portion of the first media item to be rendered on the first user device at the adjusted playback.

The present invention provides a digital broadcast receiver capable of executing functions having higher added values. The broadcast receiver receives a broadcast wave of a digital broadcast service, controls an operation including activation and end of an application that is in cooperation with a broadcast program based on application-related information, and selects control relating to reactivation of the application based on a user's operation. If activation of the application is requested after the end of the application, the broadcast receiver controls the reactivation or non-reactivation of the application in accordance with the selection of control by the user.

A play control method includes obtaining a playing state of at least one of a plurality of terminals playing a same video; and controlling a playing progress of at least one of the plurality of terminals when the playing state meets a preset condition. Using the disclosed play control method and apparatus for a plurality of terminals playing a same video, playing synchronization of the plurality of terminals can be maintained under a premise of ensuring that the plurality of terminals do not miss each video segment, so that no communication barrier is resulted due to asynchronous video playing during interactions between users who watch the same video, thus being able to improve user experience.
