Embodiment 1

[0025] Generation and transmission of region identifiers (RIDs)

[0026] In order to realize an effective method of obtaining a unique area identifier agreed in advance, this embodiment defines a complete set of session protocols for guarantee.

[0027] Parameters such as the frequency and symbol rate of the on-demand service, and the PID of the RID package are inserted and broadcast in the NIT table of the DVB system EPG in the form of a private descriptor, and are stored in the memory of the set-top box after receiving it. The relevant information of the frequency point where the service is located will not be lost; the information can also be updated in real time through the network. When planning on-demand service frequency units, 1-2 frequency points will be selected as the entrance of on-demand service, which are called on-demand service frequency points. STB defaults one of the frequency points as the on-demand service frequency point. The RID and related information o...

Embodiment 2

[0055] see figure 1 . The device of the present invention comprises a central content storehouse 1, multiple group policy servers 3 and media servers 4, multiple modulators 5 and a plurality of user terminals (STB) 6, all service contents are stored in the central content storehouse, through the CDN network 2 Connect with the media server 4, the media server broadcasts the service content through the HFC network 7, there are multiple modulators in the HFC network, and each modulator covers a plurality of user terminals (only one STB is shown in the figure); A list of on-demand service channel resources in the covered HFC network, and a strategy for optimizing channel resource allocation is preset; user terminal 6 communicates with policy server 3 through two-way interactive network 8 at the same time; modulator 5 has the ability to generate area identifiers (RID) mechanism, and issued to the covered user terminal 6; the region identifier (RID) generated by the modulator gener...

Embodiment 3

[0057] see figure 2 . In order to realize the method of the present invention, in the HFC network, in step 101, the policy server completes the pre-deployment of the overall system routing strategy, and then in step 102, the modulator generates a network information table (NIT ), which contains the unique area identifier RID of the covered area; step 103 is to insert Main_Frequency_Descriptor in the NIT of any fixed frequency point, which contains the relevant information of the frequency point where the on-demand service is located; in step 104, the user terminal (STB) Obtain information about the frequency point where the on-demand service is located; in step 105, the user terminal can obtain the RID of the area it belongs to at the predetermined frequency point where the on-demand service is located; The network submits a service request to the policy server, which includes RID, user information, information about the required service content, etc.; after receiving the re...

Abstract

The invention relates to a method and a device for positioning the terminal area of users in HFC network. The invention divides a solution server into a plurality of areas and memorizes correspondent label information and then sends the label to a user terminal. When the user terminal is communicated with the solution server, the label of the area is feedbacked to the solution server, acknowledging the solution server of the belonged area of the user terminal and providing relevant service content correspondently. The user terminal of the invention does not rely on the poison in web tree, with higher reliability of positioning.

Description

technical field [0001] The invention belongs to the field of broadcasting and television, in particular to a method and a device for determining the area position of a user terminal in an HFC network. Background technique [0002] At present, my country's urban and rural areas have generally deployed a hybrid fiber and coaxial cable (HFC) TV network to send audio / video signals to end users. HFC network is usually a unidirectional tree network. In the system with on-demand function composed of HFC and two-way interactive network, the video server and modulator (QAM) equipment can be distributed in the main headend, sub-headend or optical node, and the video server and modulator (QAM) equipment can be distributed to different equipment groups through space division multiplexing. Provide services to end users within the coverage area. It can be seen that such a mechanism is very necessary: ​​the user terminals in the entire HFC network are divided into regions in a certain wa...
