Abstract: A method, an apparatus and a medium for optimizing allocation of switching resources in the polymorphic network. The method selects the ASIC switching chip, FPGA and PPK software switching on the polymorphic network element based on machine learning, and specifically comprises the following steps: manually pre-configuring, formulating basic rules for polymorphic software and hardware co-processing; offline learning, designing training configuration in the offline learning stage to capture different switching resource usage variables, running experiments to generate the original data of a training classifier, and using the generated performance indices to train the model offline; and online reasoning, obtaining switching resource allocation advises, and updating modality codes according to the switching resource allocation advises.

Abstract: Provided are a method for realizing a video information preview, a client and a storage medium. The method for realizing a video information preview comprises: when it is detected that a progress bar is dragged, according to position information about dragging, positioning (100) corresponding preview information from a description file, wherein the description file is used for describing the preview information; and presenting (101) the positioned preview information.

Abstract: The present disclosure provides a method and device for processing a public event through key distribution, and a set top box. The method includes: creating a sub window, and loading a third-party page to the sub window; displaying the sub window on a current page, and hiding a main window; and distributing a key message to the main window and the sub window, after receiving the key message; where the key message is used to enable the main window or the sub window to make a corresponding response based on a type of the key message.

Abstract: A multicast transmission method for OTT media is provided. According to the method, a terminal sends media description request information corresponding to OTT media to a multicast server; the terminal receives media description information fed back by the multicast server based on the media description request information, wherein the media description information may include multicast information, and the multicast information may include multicast group information; and the terminal receives, according to the multicast group information, a multicast packet from the multicast server, wherein the multicast packet is generated by encapsulating a media index file corresponding to the media description request information and/or a media content file corresponding to the media description request information.
