Problems solved by technology

The number of users of the IPTV system is very large. This polling method produces a large delay, and even causes the user to be unable to watch the program for a period of time after turning it on.
[0011] In addition, in the existing technology, the EPG is delivered through the broadcast channel. This type of EPG is the same for all users, and cannot provide user-customized EPG, which greatly reduces the flexibility of IPTV services.

[0133] Embodiment 1: A user acquires an EPG, subscribes to a service, and acquires service control information through an interactive channel.

[0134] Fig. 6 is a schematic flowchart of the first embodiment of the present invention. Referring to Fig. 6, the process of the first embodiment of the present invention includes the following steps:

[0135] Step 101, the terminal obtains the address of the EPG. In this step, the traditional DVB-H bootstrap process or the attachment process of the interactive network can also be used to obtain the address of the EPG.

[0136] Step 102, the terminal requests the EPG from the SM according to the obtained EPG address.

[0137] Step 103, the SM returns the EPG to the terminal.

[0138] Step 104, the user browses the EPG information and chooses to subscribe to a certain program.

[0139] Step 105, the terminal sends a program subscription request to the SM.

[0140] In step 106, the SM returns a program subscription response, and at...

[0142] Embodiment 2: The interaction network interacts with the broadcast network to determine user location information and assist IPTV services.

[0143] Fig. 7 is a schematic flowchart of the second embodiment of the present invention. Referring to FIG. 7, the process of the second embodiment of the present invention includes the following steps:

[0144] Step 201, the user requests a certain program through the interactive network. When the IMS is used for service control, the request may use a SIP request (Invite) message.

[0145] In step 202, the interaction network interacts with the broadcast network to obtain location information of the broadcast network where the user is located.

[0146] In the NGN network, the exchange of the above information can be carried out through RACS / NACS.

[0147] Step 203, the user requests a program from the SM, carrying the location information of the broadcast network

[0148] In step 204, the SM finds that the IPE does not have t...

[0154] Embodiment 3: Carry the identification information of the broadcast network through the broadcast channel, and carry this information when the user makes a service request through the interactive network, thereby optimizing the management of the IPTV service

[0155] Fig. 8 is a schematic flowchart of the third embodiment of the present invention. Referring to FIG. 8, the process of the third embodiment of the present invention includes the following steps:

[0156] In step 301, the SM delivers configuration information to the broadcast network. The configuration information may include identification information of the broadcast network, such as DVB network identification, and the identification of the IPE in the network.

[0157] In step 302, the broadcast network saves the configuration information.

[0158] In step 303, the broadcast network carries identification information of the broadcast network such as the DVB network identification and the identification of...

Abstract

The invention discloses a method of implementing IPTV service in DVB-H network. A terminal obtains electronic program EPG and/or control information by interactive network. A service application entity SA transfers the media flow to the terminal. The terminal plays the media flow corresponding with the program in EPG using the said control information. The invention also discloses a system of implementing IPTV service in DVB-H network. In the DVB-H network, the associated information with IPTV service such as EPG is alternated by interactive channel, therefore the IPTV service is provided more flexibly and the service taste of user is increased.

Description

technical field [0001] The invention relates to the field of digital video broadcasting (DVB-H) network technology for handheld devices, in particular to a method and system for realizing Internet TV (IPTV) services in the DVB-H network. Background technique [0002] The background technology of the present invention relates to IPTV business, next generation network (NGN), IP data broadcasting (IPDC over DVB-H) based on DVB-H, conditional access system (Conditional Access, CA) and Moving Picture Experts Group (MPEG) 2 -Transport Stream (TS) and other technologies, which are introduced respectively below. [0003] IPTV is a live TV service developed in recent years on IP networks. This service introduces traditional TV services into IP networks, greatly expands the consumer groups of TV services, and attracts great attention from operators. In traditional live TV services, user equipment joins and leaves channels by sending Internet Group Management Protocol (IGMP) messages:...
