4. the intelligent television is used as a media synchronization application server to realize synchronization of the TV and the accompanying screen based on a WebSocket protocol;
5. and the intelligent television acquires metadata analysis service through analyzing the code stream and notifies the screen.
Before describing a specific embodiment, a system framework corresponding to the method of the embodiment of the present application is described first, and as shown in fig. 1, the system may be divided into two parts: a smart television and at least one smart terminal (i.e., a companion screen device).
The screen-accompanying device (intelligent terminal) and the intelligent television can be connected based on the DIAL protocol, and the screen-accompanying application CSA synchronizes media data with the intelligent television through the local area network, as shown in fig. 2, and the method is specifically realized as follows:
Step 1, a connection is established between a screen tracing device (intelligent terminal) and an intelligent television based on a DIAL protocol, the intelligent television analyzes a request data packet of a screen tracing, and port information is sent to the screen tracing, so that the screen tracing can be connected with the intelligent television, the intelligent television serves as a server, and the intelligent terminal serves as a client. The basic server instance (Endpoint Service) of the intelligent television terminal is established and can be realized based on Websocket protocol, including CSS-CII (Content Identification and other Information ), CSS-WC (Wall Clock), CSS-TS (Timeline Synchronization, time axis synchronization) and the like.
And 2, after the screen tracing equipment is connected with the intelligent television, analyzing a POST request initiated by the screen tracing by a server of the intelligent television, analyzing AIT data in an XML format, and analyzing out the webpage application based on H5, so that the traditional APP is saved from needing local application management to be installed and then opened.
Step 3, after the intelligent television opens the H5 webpage application, the intelligent television relays and forwards the local H5APP and the APP of the screen tracing end, so that data interaction between the two APPs is realized, wherein the screen tracing application CSA sends a request packet after establishing connection with the TV, and then the TV response packet contains endpoint information of other servers, so that connection is established with the other servers; and the web application of H5 acquires port information of other servers through JSAPI defined by the OIPF standard so as to establish connection with the other servers.
Step 4, the intelligent television analyzes the data of the broadcast code stream of the broadcast interface through an analysis unit of the intelligent television, including the analysis of AIT (application information table), the analysis of metadata analysis servers (Material Resolution Service, MRS) and the like; the APP analyzed by the AIT comprises a self-starting type or a type requiring a user to trigger starting through remote control, and the like, but is based on the webpage, the APP can operate without local installation, MRS data can be notified to the companion screen after the subsequent CII service is established, and therefore the companion screen can acquire more data information from the server.
Step 5, the local APP (including the APP started by parsing XML AIT or code stream AIT) receives the control of CSA, and converts the control into the interface call for calling OIPF, and controls TV behaviors such as pause, play, fast forward, fast backward and the like;
And 6, establishing connection between the APP and the CSS-CII of the smart television, wherein the smart television can send out a notification packet which contains information such as CSS-TS, CSS-WC, CSS-MRS and the like, and the connection depends on how much the smart television is used for realizing the functions.

This process is repeated until the accuracy is reached.
In step 8, since APP is developed by broadcasters or third parties cooperated with broadcasters, after the previous steps, the H5 web application and the screen-accompanying application CSA can establish communication in the local area network, and the network delay is small, compared with the communication through the server of the broadcasters, especially in the interactivity of live programs, if more users watch programs at the same time, the service is stressed, and the delay is increased, so that the participation experience of the users is affected. Therefore, the user can better use the broadcaster to provide additional services through the APP, and a better experience environment is provided.
