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.

The present disclosure relates to a content recommendation method, device and system. The method includes: recommending a content in a content set to a user based on an average recommendation probability; collecting feedback information on the recommended content from the user's client, wherein the feedback information includes display information and click information, the display information including displaying times and displaying timing of the recommended content on the client, and the click information including clicking times and clicking timing of the recommended content on the client; and determining a sequence of preferred contents from the contents in the content set according to the feedback information, so as to recommend a content to the user based on the sequence of preferred contents. Respective aspects of the present disclosure recommend contents based on a user's feedback so that it is possible to perform reasonable and effective content recommendation for random users who have less click behaviors.

The present disclosure provides a method and device for assessing quality of multimedia resource, wherein the method includes the steps of: determining a cumulative distribution vector of the multimedia resource according to indicator data for describing user behavior on the multimedia resource; determining an upper boundary vector and a lower boundary vector of the multimedia resource according to the cumulative distribution vector; and determining a quality score of the multimedia resource according to the cumulative distribution vector, the upper boundary vector, and the lower boundary vector. The present disclosure can better describe the quality of multimedia resource, and has a great operability. Moreover, after the quality of multimedia resource is assessed by using the quality assessment method of multimedia resource in the examples of the present disclosure, the feedback of online behaviors can be reflected on the final dynamic and optimized ranking and recommendation of the multimedia resource.

Method and device for assessing quality of multimedia resource

The present disclosure relates to a composite cable, which comprises a first wire assembly and a second wire assembly, and each wire of the second wire assembly is surrounded by an insulating layer. The composite cable further comprises: a sheath made of insulating material and configured to enclose the first wire assembly and the second wire assembly; and a shield comprising different kinds of metal wires and configured to surround the first wire assembly, wherein the first wire assembly is capable of transmitting signals, and the second wire assembly is capable of transmitting power supply. The composite cable according to the present disclosure is excellent in shielding performance for different requirements.

The present disclosure relates to a motion compensation matching method and system for video coding. The method comprises: a CPU extracting a current frame image and a reference frame image from a video to be processed and sending the extracted frame images to a GPU; the GPU performing interpolation process at least once on the reference frame image to obtain a plurality of interpolation images; the GPU dividing the current frame image to obtain a plurality of prediction blocks; the GPU, according to each of the prediction blocks, performing block matching search in the reference frame image and each of the interpolation images; according to a result of the block matching search, determining a motion vector of a desired image block of the current frame image. The present disclosure uses GPU to execute large amounts of computation for interpolation and division of the frame images and block matching search, and uses CPU to process a small amount of computation. Since GPU is used to process search, which can be the most complicated and the most energy-consuming part of the coding process, the large-scale concurrency of the graphics card can be sufficiently utilized, and thus the video coding speed can be significantly increased.

Motion compensation matching for video coding

The present disclosure relates to a method and apparatus for controlling interface display. The method includes: determining whether or not a first interface switching condition is satisfied in a case where a first display interface of an application is being displayed; and switching the first display interface being displayed at present to a second display interface of the application in a case where the first interface switching condition is satisfied, wherein the first display interface is associated with authentic user information, and the second display interface is associated with virtual user information. Examples of the present disclosure enable quick interface switching and thus provide the user with more convenience and improved experience in using the terminal device.
