Method and device for identifying roaming of digital TV user

Abstract

The embodiment of the invention provides a method and a device for identifying the roaming of a digital TV user. The method comprises the following steps: receiving cable TV sub-network information transmitted by subscriber terminal equipment; determining an access area of the subscriber terminal equipment according to a corresponding relationship between a preconfigured cable TV sub-network and a roaming area and the cable TV sub-network information; and comparing the access area of the subscriber terminal equipment and the roaming area attributive to the subscriber terminal equipment to determine whether the subscriber terminal equipment roams or not. By adopting the method and the device, the roaming of Cable VOD subscribers among different areas can be identified, thereby the operating loss caused by different charges among different areas is avoided.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a method and device for identifying roaming of a digital television user. Background technique [0002] The current interactive TV can be divided into two types according to the different ways of sending media streams. One is IPTV (Internet Protocol Television, Interactive Network Television), which sends media streams through the IP network, generally called IP VOD (Video on Demand, video on demand); the other is DTV (DigitalTelevision, digital television). Sending media streams through the Cable network is also called Cable VOD. [0003] In the prior art, the sources of media streams provided by IP VOD and Cable VOD are output in IP form. In order to transmit the media streams in IP form from the Cable network, there needs to be a conversion gateway between the IP network and the Cable network. That is, IP QAM (Internet Protocol Quadrature Amplitude Modulation, IP quadrature...

AI Technical Summary

Problems solved by technology

[0007] 1. The method of IP address to distinguish the actual access area of ​​the user terminal is not accurate enough, and there are many IP address segments that need to be configured, which is difficult to maintain; and when the IP address is allocated by DHCP, multiple areas may share the same network segment Therefore, it is impossible to accurately know the actual access area of ​​the user terminal through the IP address

[0008]2. When Cable operators need to use broadband networks of other operators, it is more difficult to accurately obtain and maintain the corresponding relationship between IP address segments and regions

For example, some users have already subscribed to telecom broadband. In order to save the cost of network transformation and avoid the trouble of changing broadband service providers, radio and television operators can use the IP access network provided by telecom operators to carry out VOD services. The relationship between the user's IP address and the user's location may not be provided to the radio and television operator, and even if it is provided, it may not be real-time and accurate. At this time, it is difficult for the radio and television operator to know through the IP address provided by the telecom operator. The area where the user terminal accesses

[0009]3. The IP address is easy to forge, thus deceiving the actual access area of ​​the operator

The existing technology is very easy to do IP address spoofing, so that the method of actually accessing the network through the IP address area of ​​the user is invalid
