Group_type_area//4bit, is grouped according to user region

Whether group_type_pay//2bit, pay packet according to user

Group_type_institution//3bit, is grouped according to user's institutional affiliation

If(transport_type==" 0 ") // resource issues carrier DVB

{

Transport_stream_id//16bit, transport stream identification accords with

Original_network_id//16bit, original network identification accords with

Network_id//16bit, network identifier

Service_id//16bit, task identifier

Event_id//16bit, event ID

}

If(transport_type==" 1 ") // resource issues carrier OTT-1

{

ott_acotion_weburl//128bit

}

Dvb_action_type//4bit, 1 restarts Set Top Box, 2 granting advertisements, 3-customizing messages,

}

Below the structure of above-mentioned private setting descriptor is specifically described.

Descriptor_tag: descriptor tag, 8bit field, for identifying different private setting descriptors. Being defined herein as 0x80(inside SI specification, 0x80-0xFE is the descriptor tag of user's self-defining), represent that this private setting descriptor is programming association descriptor, be unique mark of programming association descriptor.

Descriptor_length: descriptor length, 8bit field, provides the byte number of private setting descriptor after this field.

Is_used_group_type: grouping field judges whether to use label (grouping field also can be claimed to judge label), 3bit, for judging whether to ignore some grouping field (namely abandoning some grouping information), optimize and issue data, STB terminal is reduced and judges number of times, such as event one: a-quadrant charges paid school, event two: B region non-paid school, under a certain situation, need the school in two events is all issued same content of announcement, at this moment, it is accomplished by front end to describe one and do not judge region, whether pay, only judge the data type of class of subscriber. initial definition grouping information is three packets, the probability related to such as following table (in table, 1 representative does not judge, 0 represents judgement):

Sequence number	Region	Pay	Class of subscriber
				1	0	0	0
2	0	0	1
				3	0	1	0
4	1	0	0
				5	0	1	1
6	1	0	1
				7	1	1	0
8	1	1	1

According to upper table it can be seen that the value is_used_group_type of event one, two is 110, namely do not judge region and whether payment field is grouped. It will be clear that also can as required grouping information be extended, for instance increase or delete number and amendment packet content.

Group_version: packet version number, 6bit, is used for recognizing the need for update packet configuration.

Group_type_area: user area is grouped, 4bit is used for judging user region (namely the user of the present invention refers to STB terminal).

Group_type_pay: user charges situation is grouped, 2bit is used for judging whether user pays.

Group_type_institution: class of subscriber is grouped, 3bit is used for judging which classification mechanism user belongs to, such as school, government, hospital etc.

Transport_type: resource transmission type, for identifying the approach that private setting descriptor issues, the transport-type that private setting descriptor provides can be the transmission stream of DVB standard and the Internet based on ICP/IP protocol.

Transport_stream_id: transport stream identification accords with, 16bit field, in a transmission system, is used for identifying unique transmission stream.

Original_network_id: original network identification accords with, 16bit field, for providing the network identifier of original transmitted system.

Network_id: network identifier, 16bit field, for providing the network identifier of transmission system.

Service_id: task identifier, 16bit field, one business of unique mark in the transmission stream (TS) described by programming association descriptor.

Event_id: event ID, 16bit field, one event of unique mark in the transmission stream (TS) described by programming association descriptor.

Below the step of the inventive method first embodiment is specifically described.

In described step A, in the code stream that operator front end is play, adding private setting descriptor, this private setting descriptor deposits in the NIT(network information table of PSI information) inner, it includes grouping information and type of action information (namely needing the type of action information that STB terminal batch is performed).

In described step B, STB terminal frequency locking, resolve grouping information (such as group_type_area, group_type_pay, group_type_institution etc.) and the type of action information etc. of private setting descriptor in PSI acquisition of information NIT table.

In described step C, obtain the grouping information in the private data district of CA card, and by its with private setting descriptor in grouping information (specifically with need the grouping information judged) compare, inconsistent, abandon, jump to step B and again search grouping information, unanimously then enter next step and judge.

In described step D, according to transport_type label (i.e. resource transmission type label) in the private setting descriptor issued, it is judged that resource bearer type, 0 is DVB, and 1 is OTT.

If the type of resource carrier is DVB, then find the real resource position of concrete event according to transport_stream_id, original_network_id, network_id, service_id, event_id. These three identifiers of transport_stream_id, original_network_id, network_id can be used for searching the event in non-transmission stream. If the type of resource carrier is OTT, then resolves ott_acotion_weburl tag addresses, obtain event-resources.

In described step E, judge type of action, restart (label value is 0001), lower sending advertisement (label value is 0010) including pressure, customizing messages reports (label value is 0011), corresponding operating is performed according to type of action information and grouping information batch, such as to sending advertisement under certain group STB terminal, or report customizing messages etc. The follow-up if desired extension different value of event type definable represents different events.

M1: when STB terminal is opened an account, directly arranges grouping information at CA Ka Siyoushuojuqu;

M2: if being not provided with any grouping information when opening an account, then after access carrier network, in the code stream that front end is play, adds grouping information, and STB terminal obtains and is written into CA Ka Siyoushuojuqu;

M3: STB terminal judges whether CA Ka Zhong private data district exists grouping information, if it is present abandon private setting descriptor information, do not operate; If it does not exist, then by the grouping information write CA Ka Siyoushuojuqu of private setting descriptor definition in code stream.

The private data district opened up in STB terminal CA card, the grouping information deposited, its data structure and data are explained as follows:

Group_identity_structure () { group_version//6bit, packet configuration version number

Group_type_area//4bit, is grouped according to user region

Whether group_type_pay//2bit, pay packet according to user

Group_type_institution//3bit, is grouped according to affiliated family mechanism

Transport_type//2bit, it is intended that issuing action type is DVB or OTT

Action_type//4bit, it is intended that action type

Action_type_time//8bit, preserves reboot operation time last time

Reserved_future_use//3bit, retains future usage } each field semantic as follows:

Group_version: packet version number field, 6bit, is used for identifying different grouping version, in order to follow-up renewal packet configuration, additions and deletions data field.

Group_type_area: user area grouping field, 4bit, arranged when issuing CA card and using to user, uses, 16 regions of maximum support when being grouped with user area.

Group_type_pay: user charges situation grouping field, 2bit, whether, when user orders sponsored program, the PSI/SI information issued by front end is arranged, pay with user and use when being grouped.

Group_type_institution: class of subscriber grouping field, 3bit, arrange when issuing CA card and using to user, as user can be divided into school, hospital, government, could support up 8 class of subscribers.

Transport_type: action type field, 2bit, the PSI/SI information issued by front end is arranged and preserves, and is DVB or OTT passage for indicating the operation currently completed, if the latter, need to use other fields further.

Action_type: preserve the action_type type of transmission stream in the action_type in the private data district of CA card, prevents repeatedly restarting problem with action_type_time field and occurs.

Action_type_time: preserve reboot operation time last time, prevent from repeatedly restarting in the subscriber computer top box short time in conjunction with action_type.

Reserved_future_use: retain future usage, retains extension in future and uses.
