Problems solved by technology

[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
[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

Embodiment 1

[0028] An embodiment of the present invention provides a method for identifying roaming of a digital TV user, which will be described in detail below with reference to the accompanying drawings.

[0029] figure 2 For the method flowchart of this embodiment, please refer to figure 2 The method for identifying digital TV user roaming in this embodiment is applied to the management server, and the method mainly includes:

[0030] 201: Receive the cable television (Cable) subnet information sent by the user terminal equipment;

[0031] In this embodiment, the user terminal equipment may be a set-top box STB, such as image 3 shown. The set-top box STB receives the code stream with the Cable subnet ID from the Cable network, judges the Cable subnet it is in according to the Cable subnet ID, and sends the Cable subnet information to the management server.

[0032] In this embodiment, the Cable network can receive code streams with different Cable subnet IDs from the code strea...

Embodiment 2

[0057] The embodiment of the present invention also provides a management server for identifying the roaming of digital TV users. The embodiment will be described below with reference to the accompanying drawings.

[0058] Figure 5 For the schematic diagram of the composition of the management server in this embodiment, please refer to Figure 5 , the management server for identifying digital TV user roaming in this embodiment mainly includes:

[0059] The receiving unit 51 is configured to receive the Cable subnet information sent by the user terminal equipment;

[0060] An access area judgment unit 52, configured to determine the access area of ​​the user terminal device according to the pre-configured correspondence between the cable TV subnet and the roaming area and the Cable subnet information;

[0061] The roaming identifying unit 53 is configured to compare the access area of ​​the user terminal equipment with the roaming area to which the user terminal equipment be...

Embodiment 3

[0070] The embodiment of the present invention also provides a code stream sending device, which will be described below with reference to the accompanying drawings.

[0071] Figure 6 For the schematic diagram of the composition of the code stream sending device in this embodiment, please refer to Figure 6 , the code stream sending device of this embodiment mainly includes:

[0072] Synchronization unit 61, used to synchronize the CATV subnet ID with the management server;

[0073] The sending unit 62 is configured to send code streams containing different cable TV subnet IDs to the user terminal equipment after the synchronization unit 61 and the management server have synchronized the cable TV subnet ID, so that the user terminal equipment can receive The CATV subnet ID in the received code stream determines the CATV subnet it is in, and sends the CATV subnet information to the management server, so that the management server can The corresponding relationship between t...

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...
