Embodiment Construction

[0011] Program storage video server (005): purchase or rent a standard commercial video server. Universal clear stream IP set-top box (006): A common commercial set-top box software and hardware platform that can decode clear streams is used as a clear stream IPTV set-top box (006). The developed software is installed on the set-top box. User management system (SMS) server (004): The hardware of the server adopts standard commercial server, and the database in the software adopts standard commercial database software. Self-developed user management system (SMS) application software installed on the server, the software realizes user management functions such as user account opening, account cancellation, service type, video program package type, and validity period management. Conditional Access System (CAS) server (003): The hardware of this server is a standard commercial server, and the conditional access system application software has been developed by itself.

Abstract

The invention provides an IPTV hardware encryption transmission broadcast control system for the features of large video data volume transmitted on an IPTV network and high requirements for real-time performance and continuity. The system is formed by a scrambling machine (002), a conditional access system (CAS) server (003), a subscriber management system (SMS) server (004), a program storage video server (005), a general clear stream IPTV set top box (006) and a USB video hardware decryption disc (007). The video stream is subjected to real-time encryption and decryption processing through special hardware equipment in the whole transmission process; the encrypted real-time or non-real-time large-data-volume videos are transmitted on the internet; and the system is specially provided with the scrambling machine (002) for carrying out encryption and decryption on the video stream through hardware and the USB video hardware decryption disc (007), utilizes the standard DVB transport stream (TS) as a system transmission basic data format, and supports various standard video formats, including MPEG1, MPEG2, H264 and H265 and the like, as well as data transmission protocols of UDP, HTTP and HLS and the like.

Description

technical field [0001] This project involves Internet digital video and network security transmission, copyright protection and other fields. Background technique [0002] In recent years, with the rapid development of the Internet, Internet TV has also flourished rapidly. Internet TV can provide high-quality video programs, users can choose broadband IP online video programs very freely, realize the substantial interaction between media providers and media consumers, and provide a vast emerging market for network developers and program providers. However, IPTV currently has problems such as strong hotlinking, difficulty in charging, and easy interception and viewing. Hotlinking refers to content that service providers do not provide services themselves, bypass other beneficial end user interfaces (such as advertisements) through technical means, and directly provide end users with service content of other service providers on their own websites. Defraud end users of brows...
