As shown in Figure 1D, the notification message obtaining system includes: a terminal for receiving the notification message link message, and from Obtain the notification message link information in the notification message link message, obtain the notification message according to the notification message link information, and the notification message link message is business information; the SP (CP) server is used to set the notification message link information in the business information, and Send the service information to the terminal.

Based on the notification message obtaining system under the IPTV architecture shown in FIG. 1A , the embodiment of the present invention also discloses a method for obtaining notification messages. Specifically, the terminal receives a notification message link message, and the notification message link message includes: a service provider list, a broadband content guide search list, or service information; obtains notification message link information from the notification message link message; according to the Notification message link information to get the notification message.

Since notification messages are divided into default notification messages and service-related notification messages, the methods for obtaining different notification messages are different. The following describes the acquisition mechanisms of default notification messages and service-related notification messages through Embodiments 2 to 5. Since the default notification messages can be divided into: SD&S-related default notification messages, SP-related default notification messages, and BCG provider-related default notification messages, Embodiments 2 to 4 describe the procedures for obtaining the above three default notification messages.

Embodiment two

This embodiment describes the process of obtaining SD&S related default notification messages.

The access information of SD&S-related default notification messages is obtained after the terminal accesses the SD&S entry point to obtain the SP list, and the terminal sets this information so that the terminal can obtain SD&S provider-related messages. The specific process is shown in Figure 2.

Step 201, the message distribution module on the SD&S server transmits the access information of SD&S-related default notification messages to the interaction module on the SD&S server.

The interactive module on the SD&S server sets the SD&S-related default notification message access information (NotificationAccessInfo) in the service provider list ("Service Provider(s) discovery record"), and the default notification message access information is in the service provider list See the description below for the location.

Step 202, after the terminal obtains the entry point address of the SD&S server, the terminal joins the multicast group through the IGMP protocol to obtain the service provider list, or uses HTTP (Hyper Text Transport Protocol; Hypertext Transfer Protocol) to request the service provider list.

Step 203, the SD&S server sends the service provider list to the multicast group with DVB STP (SD&S Transport Protocol, service selection and search information transfer protocol) or to the terminal with HTTP protocol.

Step 204, after receiving the service provider list, the terminal performs related processing according to the notification message access information (NotificationAccessInfo) in the service provider list:

If the NotificationAccessInfo only contains the port number, it means that in the current session, the Notification is transmitted on the port; the terminal is set to listen to the port;

If the NotificationAccessInfo contains an IP multicast address and a UDP (User Datagram Protocol, User Datagram Protocol) port number, it indicates that the Notification will be sent to the port under the multicast group; the terminal joins the multicast group and listens to the multicast group the port under;

If the NotificatinAccessInfo contains an IP unicast address, it indicates that the terminal can request to send Notification through this address.

Step 205, when a message source in the SD&S server generates an SD&S-related notification message, it transmits a NotificationEvent (notification message event) to the message generation module on the SD&S server, and the notification message event includes the attributes of the notification message.

Step 206, the message generating module generates a notification message according to the attribute of the notification message.

Step 207, after the notification message is generated, the message generation module sends the notification message to the message distribution module, so that the message distribution module distributes the message to the terminals through unicast or multicast.

Step 208, the distribution module uses RTP (Real-time Transport Protocol, real-time transport protocol), UDP or FLUTE (File Delivery over Unidirectional Transport, unidirectional channel file transfer protocol) protocol to distribute notification messages.

Step 209, the terminal receives the notification message.

Optionally, in steps 201-204, the access information of the notification message may also be obtained in other ways. If the terminal has already obtained the notification message, the address of the notification message may be obtained according to the existing notification message.

√ Obtain the link information of the notification message from the default setting file, that is, obtain the well-known IP address (constant address of the entry point of SD&S related messages) and port number from the default setting file. If there is no address and only the port number, it indicates the address of the entry point with SD&S same;

√Request DNS server to resolve “_dvbservdsc._tcp.services.dvb.org”, “_dvbservdscnt._tcp.services.dvb.org” and

"dvbservdsc._udp.services.dvb.org",

"dvbservdscnt._udp.services.dvb.org", the resolved address sent by the DNS server to the terminal is the address of the entry point of SD&S and the address for obtaining the message service corresponding to the entry point;

√HNED requests an address from the DHCP (Dynamic Host Configuration Protocol) server, and DHCP assigns an IP address to the terminal and at the same time sends a domain name (such as: example.com) to the terminal through DHCP Option 15; HNED bases on this domain name, Request DNS server to resolve "_dvbservdsc._tcp.example.com", "_dvbservdscnt._tcp.example.com", "dvbservdsc._udp.example.com", "dvbservdscnt._udp.example.com", DNS server sends to the terminal The resolved address is the entry point address of SD&S and the acquisition address of the message service corresponding to the entry point;

√When HNED is connected to a certain network, there is also "sdEntry" in the configuration data sent by the network. This element is the address of all SD&S entry points and the access information of notification messages.

In step 201, see Table 1 for the position of the default notification message access information in the service provider list.

Table 1 List of Service Providers (Service Provider(s) discovery record)

As shown in Table 1, notification message access information (NotificationAccessInfo) can be used as a sub-element of ServiceDiscovery type.

Embodiment three

As shown in FIG. 3 , this embodiment describes searching for default notification services related to BCG.

Step 301, the message distribution module on the BCG server transmits the access information of the BCG-related default notification message to the interaction module on the BCG server.

Step 302, the interaction module on the BCG server sets the access information of the BCG-related default notification message in the BCG lookup list (“Broadband Content guide discovery record”); the content of the BCG lookup list will be described below.

Step 303, the interaction module on the BCG server sends the access information of the BCG lookup list to the SD&S server.

Step 304, the SD&S server integrates the access information of the BCG lookup list into the SP list in the service provider list, that is, the access information under the OfferingListType element in the service provider list is set as the access information of the BCG lookup list, thus The OfferingListType in the service provider list at that time is BCGOfferingType.

Step 305, after the terminal obtains the entry point address of the SD&S server, the terminal joins the multicast group through the IGMP protocol to obtain the service provider list, or uses HTTP to request the service provider list; the SD&S server sends the service provider list to the Multicast group or sent to the terminal by HTTP protocol.

Step 306, after receiving the service provider list, the terminal obtains the address information of the BCG lookup list in the service provider list (when the OfferingListType in Table 1 is BCGOfferingType, the access information under this element is the access information of the BCG lookup list information).

Step 307, the terminal requests to send or join the multicast group to obtain the BCG lookup list, and the way to obtain the BCG lookup list can be sent to the multicast group through DVB STP or sent to the terminal through HTTP protocol.

Step 308, the terminal obtains the access information of BCG-related default notification messages according to the NotificationAccessInfo in the received BCG lookup list "Broadband Content guidediscovery record":

√ If the NotificationAccessInfo only contains the port number, it means that in the current session, the Notification is transmitted on the port; the terminal is set to listen to the port;

√If the NotificationAccessInfo contains the IP multicast address and UDP port number, it indicates that the Notification will be transmitted to the port under the multicast group; the terminal joins the multicast group and listens to the port under the multicast group;

√If the NotificatinAccessInfo contains an IP unicast address, it means that the terminal can request to send Notification through this address.

Step 309 , when a message source in the BCG server generates a BCG message, transmit the attribute of the notification message to the message generation module on the BCG server, and the notification message generation module needs to generate a notification message.

Step 310, the message generation module in the BCG server generates a default notification message related to BCG.

Step 311 , after the BCG-related notification message is generated, the message generation module on the BCG server sends a notification message to the message distribution module on the BCG server, so that the message distribution module distributes the notification message.

Step 312 , the message distribution module on the BCG server distributes the notification message to the terminals through unicast or multicast, and the protocol used may be UDP, RTP or FLUTE.

Step 313, the terminal receives and processes the notification message;

In step 302, the content of the BCG lookup list is as shown in Table 2:

Table 2 BCG lookup list (Broadband content guide discovery record)

Optionally, in step 303, the interaction module on the BCG server directly sends the access information of BCG-related default notification messages to the SD&S server, so that the SD&S server integrates the access information of BCG-related default notification messages into the service provider In the SP list in the provider list, set the access information under the OfferingListType element in the service provider list to the access information of the BCG-related default notification message, and set the OfferingListType in the service provider list to BCGOfferingType. In this way, the structure in the service provider list is shown in Table 3.

Table 3 List of Service Providers (Service Provider(s) discovery record)

Embodiment four

This embodiment describes the process of obtaining the SP-related default notification service.

After entering the SD&S server through the entry point address of the SD&S server, the SD&S server uses the DVB STP protocol or the HTTP protocol to send the service provider list, and then the service provider list contains the access information NotificationAccessInfo of the default notification message related to the SP, so that , the default notification message can be obtained through the access information of the default notification message, as shown in Figure 4, the process of obtaining the SP-related default notification message is as follows:

Step 401, the message distribution module on the SP server sends the access information of the SP-related default notification message to the interaction module on the SP server.

Step 402, the interaction module on the SP server sends the access information of the default notification message related to the SP to the SD&S server, and the interaction module on the SD&S server sets the access information of the default notification message related to the SP in the service provider list, That is, the access information of the SP-related default notification message is placed as a sub-element in the service provider type (ServicesProvider Type) in the service provider list.

Step 403, after the terminal obtains the entry point address of the SD&S server, the terminal joins the multicast group through the IGMP protocol to obtain the service provider list, or uses HTTP to request the service provider list; the SD&S server sends the service provider list to the Multicast group or sent to the terminal by HTTP protocol.

Step 404, after receiving the service provider list, the terminal obtains the access information of the SP-related default notification message according to the NotificationAccessInfo of the SP-related message in the service provider list:

If the NotificationAccessInfo only contains the port number, it means that in the current session, the Notification is transmitted on the port; the terminal is set to listen to the port;

If the NotificationAccessInfo contains the IP multicast address and UDP port number, it indicates that the Notification will be transmitted to the port under the multicast group; the terminal joins the multicast group and listens to the port under the multicast group;

If the NotificatinAccessInfo contains an IP unicast address, it indicates that the terminal can request to send Notification through this address;

Step 405, when the message source on the SP server generates an SP-related message, transmit a notification message event to the message generation module on the SP server, and the notification message event includes the attributes of the notification message.

Step 406, the message generating module on the SP server generates an SP-related notification message according to the attribute of the notification message.

Step 407, after the notification message is generated, the message generation module on the SP server notifies the message distribution module on the SP server to distribute the message to the terminals through unicast or multicast.

Step 408, the message distribution module on the SP server distributes the notification message to the terminal using a protocol such as UDP, RTP or FLUTE.

Step 409, the terminal receives the notification message, and processes the notification message.

In step 402, the format of the service provider list containing the access information of the SP-related message is shown in Table 4.

Table 4 List of Service Providers (Service Provider(s) discovery record)

Embodiment five

This embodiment describes the process of obtaining service-related notification messages.

The search information of the service-related notification service is generally attached to the description information of the service. In DVB IP, service information includes: broadband program search information (Broadband content guide discovery record), broadcast program search information ("TS Full SI" Discovery Information and "TSOptional SI" discovery information), service information provided by other service providers ( Services from other Service Providers record). These pieces of information include access information for service-related notification messages. The access information of service-related notification messages is described by NotificationAccessInfo. The terminal can receive the notification message after being set through these description information. As shown in Figure 5, the process of obtaining service-related notification messages is as follows:

Step 501, the message distribution module on the SP server transmits the access information of the service-related notification message to the interaction module on the SP server. The interaction module on the SP server integrates the access information of service-related notification messages into the service list.

Step 502, the interactive module on the SP server sends the access information of the service list to the SD&S server, and the SD&S server includes the access information of the service list in the service provider list ("ServiceProvider(s) discovery record").

Step 503, after the terminal obtains the entry point address of the SD&S server, the terminal joins the multicast group through the IGMP protocol to obtain the service provider list, or uses HTTP to request the service provider list.

The SD&S server sends the service provider list and DVB STP to the multicast group or to the terminal with HTTP protocol.

Step 504: After receiving the service provider list (“Service Provider(s) discovery record”), the terminal accesses the service list according to the service provider type in the service provider list (“Service Provider(s) discovery record”) Information (that is, the address information under the OfferingListType type), requesting delivery or joining a multicast group to receive the service list provided by the SP. The format of the business list will be described later.

The service list is sent to the terminal through DVB STP or HTTP protocol.

Steps 505-510, after the terminal obtains the service list, obtains the access information of the service-related notification message according to the NotificationAccessInfo in the service list, and then obtains the service-related notification message through the access information of the service-related notification message. For specific description, please refer to the embodiment Steps 204-209 of .

In step 502, since services can be divided into: broadcasting service, broadband service and services provided by other service providers, different ways of obtaining notification messages are different for different services. The methods for obtaining notification messages for different services are described below.

(1) For broadcast service-related notification messages, the access information of the notification message can be set in the broadcast service list (Table 5, Table 6), and then the notification message can be obtained through the access information of the notification message in the broadcast service list. The service list of the broadcast mode includes two types: "TS Full SI" and "TS Optional SI". The format of the TS Full SI table is shown in Table 5, and the format of the TS Optional SI table is shown in Table 6.

Table 5 TS Full SI

Table 6 "TS Optional SI"

(2) For notification messages related to broadband services, NotificationAccessInfo information can be set through the program information (ProgramInformation) and service information (ServiceInformation) in the BCG. The data format of NotificationAccessInfo is shown in Table 7:

Table 7 NotificationAccessInfo

When NotificationAccessInfo is set in the program information (ProgramInformation), NotificationAccessInfo can be used as an optional element of the program information, a sub-element of the sub-element BasicDescription of the program information, or a notification message as a related content whose associated type needs to be indicated as a notification information.

When the NotificationAccessInfo is set in the service information (ServcieInformation), the NotificationAccessInfo can be used as an optional element of the service information.

(3) For business-related notification messages provided by other service providers, the access information of the notification messages can be set in other service provider service information ("Service From other Services Providers" record), and the other service provider service The format of the information is shown in Table 8.

Table 8Service From other Services Providers″record

Embodiment six

In Embodiments 2 to 5, after the terminal receives the notification message link message, it can obtain the notification message link information from the notification message link message, then obtain the notification message according to the notification message link information, and perform different processing according to the characteristics of the notification message, This embodiment describes a method for obtaining notification message link information from a notification message link message.
