- the RTSP server directly interacts with the set-top box, and the media server is used for media processing and transmission.
- FIG. 4 a method for implementing side-by-side downloading in an IPTV system is provided, which includes the following steps:
- the set top box sends an RTSP signaling description (Describe) request message to the RTSP server, where the request message carries the content requested by the user;
- the RTSP server After receiving the Describe request message, the RTSP server searches for content that is requested by the user in the Describe request message, and records the code rate of the content.
- the set top box sends a SETUP request message to the RTSP server, where the current bandwidth information of the terminal is carried in a transport field of the request message.
- S304 The RTSP server applies for a resource to the media server.
- S305 the resource application is successful, the media server responds to the RTSP server;
- the set top box determines whether the current situation satisfies the condition of downloading while playing, and if yes, asks the user whether to enable the download function while playing; wherein, after receiving the SETUP response message, the set top box retrieves the response message.
- the set top box sends a setting parameter (SET_PARAMETER) request message to the RTSP server, carrying a field indicating that the terminal supports the download function while playing, and file information to be downloaded by the user; for example, the SET_PARAMETER
- the request message can be:
- the RTSP server requests a resource from the media server.
- S311 The RTSP server sends a SET_PARAMETER response message to the set top box, carrying the path, user name, password and other information of the file to be downloaded;
- step S309 ⁇ S311 after receiving the SET_PARAMETER request message, the RTSP server queries the media server for the existence of the file content to be downloaded by the user. If yes, the available resources are allocated to the user, and the ftp is queried. The username and password encrypt the above information and bring it to the set-top box via the SET-PARAMETER response message.
- S312 The set top box starts to play and download the process;
- S314 The media server sends a code stream to the set top box.
- S315 The set top box downloads, according to the SET_PARAMETER response message returned by the RTSP server, the content of the file to be downloaded by the user to the media server;
- S316 the media server sends the content of the file to be downloaded by the user to the set top box;
- S317 During the downloading and playing process, the set top box sends a GET_PARAMETER request message (heartbeat message) to the RTSP server, where the packet information of the currently playing media file is carried;
- a GET_PARAMETER request message heartbeat message
- the RTSP server notifies the streaming media server to dynamically adjust the download bandwidth according to the information in the GET_PARAMETER request message, and the user's viewing is preferentially satisfied;
- the streaming server adjusts the download bandwidth and returns a GET_PARAMETER response message to the RTSP server;
- the RTSP server sends a GET_PARAMETER response message to the terminal. If the RTSP server continues to receive the packet loss information sent by the set top box, then steps S318-S320 are continued until the packet loss information is no longer received. It can be seen from the above-mentioned embodiments that the method, the terminal, the CDN server and the system for downloading while playing in the IPTV system provided in the above embodiments are compared with the prior art, and RTSP and FTP (File Transfer Protocol) are implemented in the IPTV system.
