[0002] The network multimedia terminal requests audio and video data from the media platform through the broadband network, and provides audio and video playback services to users. It has been widely deployed and used. A large number of IPTV terminals and OTT terminals have entered all walks of life. The maintenance and maintenance of these large network multimedia terminals Troubleshooting has become a time-consuming and labor-intensive but important task, which affects the operation quality of the overall system
During maintenance or troubleshooting, the general method is that maintenance personnel go to the site to provide manual services, or the terminal reports logs for post-event analysis. The former is expensive, while the latter has delays and limited processing methods.

Embodiment Construction
[0037] The specific implementation of the present invention will be further described below.
[0038] In the transit proxy server, the basic data structure is to construct a set table fd_map of transit proxy sessions. Each cell entry in the table holds a session information:
[0039] fd : the socket descriptor with the terminal command line operation interface;
[0040] peer_fd: the socket descriptor with the media terminal;
[0041] peer_mac : the mac of the media terminal, the ID;
[0042] state : the current remote control state;
[0043] read_buf : cache of remote control data;
[0044] The transfer proxy server will save the connection information of the media terminal and the remote control session information in this table.
[0045] On the media terminal, after receiving a request to create a remote control, execute the following logic:
[0046] Open a pty pseudo-terminal:
[0047] pty = getpt();
[0048] t = open(tty_name, O_RDWR | O_NOCTTY);
[0049] And star...

The invention belongs to the technical field of network multimedia terminals, in particular to a remote access control system for a large number of multimedia terminals in a public network environment. The invention includes: a transfer proxy server, used to monitor a specific port, accept the connection of the media terminal, maintain and record the connection state; accept the operation request of the command operation terminal; the media terminal is used to respond to the remote control request, start the pty pseudo-terminal locally, and construct Shell interactive process, etc.; terminal command line operation interface, used to initiate control connection requests, obtain command execution output, etc. In addition, it also includes building a network event-driven programming framework to encapsulate and manage network connections, interactive signaling and control data sending and receiving. The invention realizes the remote control of a large number of terminals connected to the Internet after the NAT protocol in the public network environment, provides a convenient and fully functional remote operation and maintenance debugging method, can reduce the system operation and maintenance cost, and improve the operation quality of the system.
