Channel display control method and device that the embodiment of the present invention provides are applied in Set Top Box.
Refer to a kind of flowchart of the channel display control method that Fig. 1, Fig. 1 provide for the embodiment of the present invention, it is possible to including:
Step S11: parse SDT Service Description Table from the transmission stream received;
SDT Service Description Table (servicedescriptiontable, SDT) it is one of table most basic in digital TV network, the information of all business in network is described, including Business Name (as, channel name), type of service (e.g., video frequency program, data broadcast etc.).
In digital TV network, carrying a SDT table in the transmission stream that frequency carries, this SDT table includes the description information of each channel of carrying in this transmission stream, including the type of service etc. of the title of channel, channel.
Step S12: judge whether comprise private setting descriptor in the description information of the first channel carried in described SDT Service Description Table, carry one or two identification code in described private setting descriptor, each identification code at least one country code corresponding; Described identification code is for whether the country characterized corresponding to the country code that described identification code is corresponding is allowed to display the first channel;
First channel is any one channel in the transmission stream received in the channel of carrying.
In the embodiment of the present invention, privately owned description can be carried an identification code, it is also possible to carry two identification codes. Different values can be given, thus characterizing whether the country corresponding to the country code that described identification code is corresponding is allowed to show described first channel for identification code. Such as, when the value of identification code is 1, it was shown that the country corresponding to the country code that this identification code is corresponding allows to show described first channel, and other country does not then allow to show this first channel; When the value of identification code is 0, it was shown that the country corresponding to country code that this identification code is corresponding does not allow to show described first channel, and other country then allows to show this first channel.
Step S13: when comprising private setting descriptor in the description information judging the first channel carried in described SDT Service Description Table, it is determined that target identifying code;
When only one of which identification code in private setting descriptor, it is determined that this only one identification code is exactly target identifying code.
When private setting descriptor carries two identification codes, it is possible to determine target identifying code according to the value of two identification codes. Optionally, it is possible to determine the priority level of each identification code according to the value of these two identification codes; If the priority level of two identification codes is different, then identification code higher for priority level can be defined as target identifying code; If the priority level of two identification codes is identical, then two identification codes can being all defined as target identifying code, namely target identifying code can have two.
Step S14: judge whether there is the country code identical with locally stored country code in the All Countries code corresponding with described target identifying code;
The locally stored country code of Set Top Box can add country selection menu interface in start boot flow, and option is the country code that satellite-signal covers, and selects corresponding national code according to Set Top Box the country one belongs to.
Step S15: according to judged result, and described first channel is displayed control by described target identifying code.
A kind of channel display control method that the embodiment of the present invention provides, when needing in different countries, the first channel is displayed control, the description information of the first channel that can carry in SDT Service Description Table is added private setting descriptor, described private setting descriptor carries one or two identification code, each identification code at least one country code corresponding; Described identification code is for whether the country characterized corresponding to the country code that described identification code is corresponding is allowed to display the first channel, Set Top Box is after parsing SDT Service Description Table, when the description information judging the first channel comprises private setting descriptor, determine target identifying code, it is judged that whether the All Countries code corresponding with described target identifying code exists the country code identical with locally stored country code; According to judged result, and described first channel is displayed control by described target identifying code.
To sum up, the channel display control method that the embodiment of the present invention provides, based on country code, channel is displayed control, when a channel can not be watched in certain country, can being enumerated by the code of this country under the identification code in the private setting descriptor comprised in the description information of the first channel in SDT table, this identification code characterizes the country corresponding to the country code enumerated under this identification code and is not allowed to show described first channel. And owing to description information and first channel of the first channel in SDT Service Description Table are relations one to one, therefore, by the description information of the first channel in SDT Service Description Table increases private setting descriptor as above, can be implemented in different countries and carry out the display control of single channel, thus improve the experience of user.
Additionally, channel display control method provided by the invention, renewal process realizes simple, when needing to change a channel when the state whether certain country can show, having only to add in the description information of this channel in the SDT table of front end or delete the code of this country, Set Top Box side has only to know that the country code of Set Top Box the country one belongs to can realize the display to certain channel and control. And, after SDT table is updated, it is possible to immediately according to the SDT table after updating, channel is displayed control, the display without affecting other channels controls.
In above-described embodiment, optionally, if judging the description information of the first channel carried in described SDT Service Description Table does not comprise private setting descriptor, then perform step S16, namely show described first channel.
It is to say, when the description information judging the first channel carried in SDT Service Description Table does not comprise private setting descriptor, illustrate that this first channel can show at All Countries.
In above-described embodiment, optionally, described according to judged result, and described first channel is displayed control and may include that by described target identifying code
When judging described corresponding with target identifying code All Countries code exists the country code identical with locally stored country code, if described target identifying code characterizes the country corresponding to the country code that described target identifying code is corresponding and allows to show described first channel, then show described first channel; If described target identifying code characterizes the country corresponding to country code corresponding to described target identifying code and do not allow to show described first channel, then hide described first channel.
Concrete, when target identifying code only one of which, assume that this target identifying code characterizes the country corresponding to the country code that target identifying code is corresponding and allows to show described first channel, so, if at least one country code corresponding with this target identifying code comprises country code locally stored in Set Top Box, then illustrate that this Set Top Box the country one belongs to can show this first channel, then Set Top Box can control to show this first channel; And assume that this target identifying code characterizes the country corresponding to country code corresponding to target identifying code and do not allow to show described first channel, so, if at least one country code corresponding with this target identifying code comprises country code locally stored in Set Top Box, then illustrate that this Set Top Box the country one belongs to cannot show this first channel, then Set Top Box can control not show this first channel, namely hides this first channel.
When target identifying code has two, if two identification codes all characterize the country corresponding to the country code corresponding to identification code and allow to show described first channel, so, if the locally stored country code of Set Top Box is present in the country code that at least one identification code is corresponding, then illustrate that this Set Top Box the country one belongs to can show this first channel, then Set Top Box can control to show this first channel; And if two identification codes all characterize the country corresponding to the country code corresponding to identification code and do not allow to show described first channel, so, if the locally stored country code of Set Top Box is present in the country code that at least one identification code is corresponding, then illustrate that this Set Top Box the country one belongs to cannot show this first channel, then Set Top Box can control not show this first channel, namely hides this first channel.
Optionally, described according to judged result, and described first channel is displayed control and may include that by described target identifying code
When judging described corresponding with target recognition code All Countries code is absent from the country code identical with locally stored country code, if described target identifying code characterizes the country corresponding to the country code that described target identifying code is corresponding and allows to show described first channel, then hide described first channel; If described target identifying code characterizes the country corresponding to the country code that described target identifying code is corresponding and allows to show described first channel, then show described first channel.
Concrete, when target identifying code only one of which, assume that this target identifying code characterizes the country corresponding to the country code that target identifying code is corresponding and allows to show described first channel, so, if at least one country code corresponding with this target identifying code does not comprise country code locally stored in Set Top Box, then illustrate that this Set Top Box the country one belongs to cannot show this first channel, then Set Top Box can control aobvious not show this first channel, namely hides this first channel; And assume that this target identifying code characterizes the country corresponding to country code corresponding to target identifying code and do not allow to show described first channel, so, if at least one country code corresponding with this target identifying code does not comprise country code locally stored in Set Top Box, then illustrate that this Set Top Box the country one belongs to can show this first channel, then Set Top Box can control to show this first channel.
When target identifying code has two, if two identification codes all characterize the country corresponding to the country code corresponding to identification code and allow to show described first channel, so, if the locally stored country code of Set Top Box is not present in the country code that any one identification code is corresponding, then illustrate that this Set Top Box the country one belongs to cannot show this first channel, then Set Top Box can control not show this first channel, namely hides this channel; And if two identification codes all characterize the country corresponding to the country code corresponding to identification code and do not allow to show described first channel, so, if the locally stored country code of Set Top Box is not present in the country code that any one identification code is corresponding, then illustrate that this Set Top Box the country one belongs to can show this first channel, then Set Top Box can control to show this first channel.
In above-described embodiment, optionally, when being provided with two identification codes, by the two identification code, country can also be divided into two groups, if needing temporarily first group of country is not shown the first channel, one of which country is allowed to show the first channel when needed again, second group of country does not show the first channel for a long time, then the initial value of two identification codes all can be set to " 0 ", when first group of country of needs shows the first channel, having only to the value by identification code corresponding for first group of country change into " 1 ", amendment is flexible.
A kind of concrete example of the embodiment of the present invention is exemplified below.
In this example that the embodiment of the present invention provides, in SDT table, the description information of the first channel with the addition of private setting descriptor country_availability_descriptor, be used for describing the first channel whether effective in some country. By configuring the national code in this descriptor, describing the first channel in which country is effective (namely can show), which country to be invalid (namely cannot show, it is necessary to hide) in. Set Top Box loads the national code of the country one belongs to. Set Top Box, when carrying out program searching, by analyzing the private setting descriptor country_availability_descriptor comprised in the description information of the first channel, is compared with locally stored country code, it is determined that whether the first channel displays.
In this example, the code of private setting descriptor country_availability_descriptor describes as described in Table 1:
Table 1
Wherein, descriptor_tag is that effectively country describes mark, and default value is 0x49. It is to say, during descriptor_tag=0x49, illustrate that private setting descriptor country_availability_descriptor is used to describe the first channel whether effective in some country.
Country_availability_flag is identification code, for whether the country identified representated by follow-up enumerated country code is allowed to display the first channel. In this example, on duty when being " 1 ", represent that the first channel is effective in the country corresponding to follow-up country code (country_code), it is possible to display. On duty when being " 0 ", represent that the first channel is invalid in the country corresponding to follow-up country code (country_code), it is not possible to display. This description field can add at most two, when adding two fields, it is possible to about definite value be that the field priority of " 0 " is higher, and the country corresponding under this field is invalid. Can also definite value being about the field priority height of " 1 ", country corresponding under this field be effective.
Country_code is country code, and 24 bit fields indicate country according to ISO3166 by 3 character codes. Each character is encoded to 8 according to GB/T15273.1-1994, and is sequentially inserted into 24 bit fields. Wherein, if 3 characters represent the numeral of 900 to 999, then country_code specifies the country of one group of ETSI definition. Such as: South Africa is represented by 3 character codes " ZAF ".
Reserved_future_use is reserved field, it is possible to the extension as subsequent development uses.
Concrete,
If the description information of the first channel does not comprise private setting descriptor country_availability_descriptor, then Set Top Box is given tacit consent to this first channel and can be displayed, when namely the description information of the first channel not comprising private setting descriptor country_availability_descriptor, illustrate that the first channel can display in any one country.
When adding a country_availability_flag descriptor in privately owned description, and when its value is " 1 ", illustrating that the country enumerated under this descriptor allows display the first channel, other country forbids display the first channel.
Accordingly, if the country code enumerated under the country_availability_flag descriptor that this value is " 1 " includes the country code that Set Top Box is locally stored, then Set Top Box controls to show this first channel.
When adding a country_availability_flag descriptor in privately owned description, and when its value is " 0 ", illustrating that the country enumerated under this descriptor does not allow to show this first channel, other country can show this first channel.
Accordingly, if the country code enumerated under the country_availability_flag descriptor that this value is " 0 " includes the country code that Set Top Box is locally stored, then Set Top Box controls to hide this first channel.
When private setting descriptor is added with two country_availability_flag descriptors, and one of them descriptor value is " 1 ", when another one descriptor value is " 0 ", the priority that value is the country_availability_flag of " 0 " is higher, namely value is that the country enumerated under the country_availability_flag of " 0 " forbids showing this first channel, and other country allows to show this first channel.
Accordingly, Set Top Box using country_availability_flag descriptor that value is " 0 " as target identifying code, if comprising, in the country code enumerated under the country_availability_flag descriptor that value is " 0 ", the country code that Set Top Box is locally stored, then Set Top Box controls to hide this first channel; Otherwise Set Top Box controls to show this first channel, that is, if the country code enumerated under the country_availability_flag descriptor that value is " 0 " does not comprise the country code that Set Top Box is locally stored, no matter value is whether comprise the country code that Set Top Box is locally stored in the country code enumerated under the country_availability_flag descriptor of " 1 ", and Set Top Box all controls to show this first channel.
When being added with two country_availability_flag descriptors in private setting descriptor, and two descriptor values are " 1 ", then the country enumerated under two descriptors all allows to show this first channel, and other country then forbids showing this first channel.
Accordingly, as long as comprising, in the country code enumerated under one of them country_availability_flag descriptor, the country code that Set Top Box is locally stored, Set Top Box all shows this first channel; If all not comprising the country code that Set Top Box is locally stored in the country code enumerated under any one country_availability_flag descriptor, then Set Top Box controls to hide this first channel.
When being added with two country_availability_flag descriptors in private setting descriptor, and two descriptor values are " 0 ", then the country enumerated under two descriptors all forbids showing this first channel, and other country then allows to show this first channel.
Accordingly, as long as comprising, in the country code enumerated under one of them country_availability_flag descriptor, the country code that Set Top Box is locally stored, Set Top Box all hides this first channel; If all not comprising the country code that Set Top Box is locally stored in the country code enumerated under any one country_availability_flag descriptor, then Set Top Box controls to show this first channel.
