DVB-C（Digital video broadcast for cable）、DVB-C2、DVB-S（Satellite digital video broadcast）、DVB-S2.
It should be noted that under current DVB standard, the operator of different regions defines LCN mode difference, has
LCN is defined on network information table NIT by operator（Network Information Table）In, what is had is defined on business group
Contingency table BAT（Bandwidth Allocation Threshokd）In, what is had is defined on SDT Service Description Table SDT（Service
Description Table）In.Therefore it needs to be determined that LCN definition mode.In existing implementation, analysis can be passed through
The value of description subtab descriptor_tag defined in EPG system, to search privately owned description that operator defines；Then
By analyzing the data in privately owned description, LCN therein is stored in extract, and then according to LCN data and programme information pair
Program is ranked up.It must be carried out in view of LCN by every tricks byte purpose unique device numbering service id and program
Association, therefore LCN and service id are paired；Leading portion operator sends sequence description data by multiplexer and there was only two kinds
Situation：A kind of is one LCN that is stored with of a service id correspondence privately owned description, and such case typically occurs in SDT
In table, i.e., when LCN is defined in SDT tables by operator, it then follows this defining mode, all privately owned retouch now need to be only parsed
Stating has successional data in son, the successional data are LCN；Second of situation is that service id and LCN are fixed
Justice is in privately owned description, such as operator follows this definition pattern defined in NIT or BAT tables during LCN；In this feelings
It can be compared, find corresponding with the service id of all programs by analyzing the data in privately owned description under condition
Service id, are then looked for successional data from the data beyond service id successively, that is, think have found
LCN data.Finally service id and LCN is associated by service id with programme information, according to LCN size
Program is ranked up.
For convenience, the present invention is defined on the description that related embodiment is carried out in NIT tables with LCN.

Standard DVB（Digital Video Broadcasting-Cable, digital television broadcasting）In, each frequency has
Corresponding NIT tables and SDT tables.Wherein, NIT tables contain the information of each frequency under current network（Such as version number, transport stream
ID, frequency point parameters information etc.）With the programme information under each frequency（Such as program ID, program LCN, the type of program）.SDT table bags
The programm name of all programs containing current network and the title of supplier.
In a kind of possible embodiment, LCN information is retouched in NIT tables with logical channel descriptor
Symbol transmission is stated, its descriptor_tag is 0x83, and its structure is：
logical_channel_descriptor(){
descriptor_tag
descriptor_length
for(i=0;I<N;i++){
service_id
visible_service_flag
reserved
logical_channel__number
}
}。
It can be seen that each logical channel descriptor contain a service id and one
Logical_channel_number, so as to specify a logical channel number for each service.Pass through
Service id can just be mapped with the service id transmitted in SDT Service Description Table SDT, and wherein service id are used for
Each program is identified, the specifying information of each program, such as programm name, program frequency can be found according to the service id
Road, broadcasting initial time etc..Can be all from network information table NIT by keyword of 0x83 when parsing network information NIT
Descriptor finds logical channel descriptor, then read out description subcycle body in the first two byte simultaneously
Service id are risked, then read out most latter two byte, and low two byte second from the bottom and bit byte last
Risk No. LCN.So as to parse each pair (service id, lcn).Such as one logical_channel_descriptor
There is data below：
0x83,0x8,0x00,0x65,0xFF,0xE9,0x00,0x66,0xFF,0xEA
First data is 0x83, it is known that its correspondence logical_channel_descriptor, represents that the descriptor read is
Correctly.
Second data is 0x8, and it represents the data for also having 8 bytes after this data for reading.And this 8 number
According to being that 4 data are one group, therefore two service id and lcn can be read altogether.
3rd data and fourth data are combined into a service id：0x0065, i.e., metric 101.
5th data 0xFF, it is with being represented in binary as 1,111 1111, and highest order is ' 1 ', i.e. visible_
Service_flag is 1, and it is visible to user to represent this program, and middle 5 ' 11111 ' are nonsensical, skip over；Last two
Position ' 11 ' and the 6th data 0xE9 (1,110 1001) ' 11 1,110 1001 ' the i.e. lcn that is stitched together as binary is
1001, such first (service id, lcn) is to parse as (101,1001), and it is 101 to represent service id
The lcn of program is exactly 1001.
Same parsing is equally done to ten bit data to the 7th again, data pair as (102,1002) are obtained.Extremely
This whole data is parsed.
Step 202, when the LCN for detecting at least two TV programme is identical, at least two TV programme are determined
Institute of operator possession.
In a kind of possible embodiment, when the LCN for detecting at least two TV programme is identical, this is read at least
The country_availability_descriptor of two TV programme, reads the operator of the program from the descriptor
Institute possession.The structure of country_availability_descriptor descriptors is as follows：
country_availability_descriptor(){
descriptor_tag
descriptor_length
country_availability_flag
reserved_future_use
for(i=0,i<N,i++){
country_code
}
}
Wherein, country_flag mark can be 1 or 0, country_code are the abbreviations of country, such as " GBR " is represented
Britain, " FRE " represents France etc..The two values, which combine, is assured which country a program belongs to.Such as when
Country_availability_flag is 1, and country_code is " GBR ", then mean that this program belongs to English
State；And when it is " GBR " that country_availability_flag, which is 0, country_code, mean that this program does not belong to
In Britain.Therefore a program belonging country can be determined according to the two values.
In alternatively possible embodiment, when the LCN for detecting at least two TV programme is identical, this is read extremely
The target_region_descriptor of few two TV programme, reads belonging to the operator of the program from the descriptor
Ground.The structure of target_region_descriptor descriptors is as follows：
target_region_descriptor
descriptor_tag
descriptor_length
descriptor_tag_extension
country_code
for(i=0,i<N, i++)
reserved
country_code_flag
region_depth
if (country_code_flag==1{
country_code
}
if (region_depth>=1){
primary_region_code
if (region_depth>=2){
secondary_region_code
if (region_depth==3){
tertiary_region_code
}
}
}
}
}
Wherein country_code is used for representing the country belonging to the TV programme, and primary_region_code is used for representing
The affiliated province of the TV programme, secondary_region_code is used for representing the urban district belonging to the TV programme,
Tertiary_region_code is used for identifying county/area described in the TV programme.By parsing target_region_
Descriptor can accurately know institute of the operator possession of the TV programme.
