Therefore, when the code stream received by the display equipment is a new Zealand code stream or a non-standard code stream of the code stream with the same coding mode as the new Zealand code stream, the correct daylight saving time can be displayed when the area is in daylight saving time, and further the display equipment can display the correct time at any time in the area.
Description
Technical Field
The present invention relates to a display technology, and more particularly, to a time display method in a display apparatus and a display apparatus.
Background
Daylight Saving Time (DST), also known as Daylight Saving Time and Daylight Saving Time, is a system for artificially defining local Time for Saving energy, and the unified Time used during the implementation of the system is called Daylight Saving Time. Generally, in the early summer, the time is artificially adjusted to be faster by one hour, so that people can sleep early and early, the illumination quantity is reduced, the illumination resource is fully utilized, and the illumination power consumption is saved.
The countries where daylight savings time is adopted have different specifications. Currently, approximately 110 countries around the world are in daylight saving time each year. The time periods during which daylight savings is performed vary from country to country, and it is possible that the time zone for a country changes from GMT +02:00 to GMT +03:00 for a certain time period. Therefore, according to the area where the television is located, after the local time enters the daylight saving time, the time displayed on the television is also synchronously displayed with the daylight saving time.
To meet the above requirements, a common method is to synchronize the time of the tv based on the daylight saving time information in the code stream. Specifically, in a conventional standard code stream, time difference information, daylight saving time information and the like specified by a standard are set at a specified position in the code stream, and then, after the code stream is analyzed by a television terminal to obtain the information, the local time can be calculated, so that the display time of the television is synchronized.
However, the inventor found that the code stream of new zealand is a non-standard code stream, and although the code stream also contains time difference information, daylight saving time information and the like, the information is not at the specified position specified by the standard, so if the code stream of new zealand is analyzed by a method for analyzing the standard code stream, corresponding correct information cannot be obtained, correct daylight saving time of new zealand cannot be calculated, and further, the local time of new zealand enters daylight saving time, and the time on a television is still the original displayed time.

in response to an instruction for indicating display of an EPG user interface or a channel information user interface, when a first time offset value is determined to be different from a time zone difference value corresponding to an area where display equipment is located, adding the first time offset value and UTC time to obtain target display time; and displaying an EPG user interface or a channel information user interface including the target display time on a display;
the first time offset value refers to a time offset value of a current time system corresponding to an area where the display device is located, which is obtained from a code stream in the digital broadcast signal.
According to a second aspect of the embodiments of the present application, there is provided a method for displaying time in a display device, the method mainly includes:
in response to an instruction to instruct display of an EPG user interface or a channel information user interface;

the first time deviation value refers to a time deviation value of a current time system corresponding to an area where the display device is located, which is obtained from a code stream in the digital broadcast signal.
According to the time display method and the display device in the display device, when an instruction for indicating display of an EPG user interface or a channel information user interface is received, a first time offset value is compared with a time zone difference value corresponding to an area where the display device is located, if the first time offset value and the time zone difference value are different, the area where the display device is located is in daylight savings, the first time offset value and UTC time are added to obtain target display time, and the EPG user interface or the channel information user interface including the target display time is displayed on a display. Therefore, when the code stream received by the display equipment is a new Zealand code stream and a non-standard code stream of the code stream with the same coding mode as the new Zealand code stream, the correct summer time can be displayed when the area is in the summer time, and further, the display equipment can display the correct time at any time in the area.

Based on the display device, a digital television operator can multiplex a multi-path program into a code Stream (TS) of a digital broadcast signal according to the MPEG-2 standard, and the display device side can acquire corresponding program data by demultiplexing the received TS.
Further, for the standard code stream, the code stream also contains TDT (Time and Date Table) information. From this information, the display device can obtain UTC (coordinated Universal time) time, that is, Universal time, the UTC time refers to greenwich time based on the release of greenwich astronomical benches in england, and also refers to winter time of 0 time zone, for example, the current Universal date is 2018/10/19, and the time is 00:43: 12.
In addition, the display device may also obtain TOT (Time Offset Table) information from the code stream, and the information Table is generally received every 15 seconds or 30 seconds. The CountryCode, namely the country code, can be obtained from the information table, and then the country where the code stream is located and the country _ region _ id, namely the country regional identification code, can be judged; then, the local time difference under the current time system of the area where the code stream is located can be judged through local _ time _ offset; finally, one important information is next _ time _ offset, which represents the local time difference at the next time system of the region where the code stream is located.
The time system includes a summer time system and a winter time system, wherein the summer time system means the time system of the summer time, and the winter time system means the time system of the winter time. For the execution method of the summer Time system and the winter Time system, the universal Time in the world, namely Greenwich Mean Time (translated from Greenwich Mean Time) is adopted, according to different laws of different places, for example, in England, one hour is pulled up in three months on the basis of the Greenwich Mean Time, and the new Time is the summer Time. In October, the time is slowed down for one hour on the basis of summer time, and then winter time is formed, namely the winter time is the Greenwich standard.
In addition, the local time refers to a time calculated by using UTC time in combination with the local time zone and the execution status of the current daylight saving time, for example, the local time in beijing is obtained by UTC time +8h because the time zone in beijing is in the east 8 zone and the time in beijing does not execute the daylight saving time system; the local time of Washington is obtained from UTC time-5 h during implementation of winter time, since the time zone of Washington is located in the West 5 region, while the local time of summer is obtained from UTC time-5 h +1h, since the local time is 1 hour faster than the time of winter time due to implementation of summer time.
For the standard code stream, if the value of the next _ time _ offset is the same as the value of the local _ time _ offset, it represents that there is no daylight saving in the area, and if the two values are different, it represents that there is daylight saving in the area. The value of the next _ time _ offset is different from the value of the local _ time _ offset, which represents that the daylight savings time system is currently executed in the region. In this way, the display device side can determine that the current time, that is, the calculated time of the area where the display device is located is the daylight saving time, and add 1 hour, or certainly add 2h, 3h, or other time to the calculated time of the area where the display device is located, as the display time of the display device.
However, the code stream of new zealand is not a standard code stream, and is specifically represented as follows: even if there is daylight savings time in new zealand and the current time is experiencing daylight savings time, the values of both local _ time _ offset and next _ time _ offset are the same. Therefore, if the daylight savings time is analyzed in the above manner, after the local time in new zealand enters the daylight savings time from the original time, the display device cannot analyze the correct time, which results in that the time displayed on the display device is the original time and the daylight savings time is not displayed.
In order to solve the above problems, it is common practice to record a standard code stream, but the cost required by this method is relatively high. Therefore, the embodiment reversely deduces the code stream by capturing the log (log) and further repairs the code stream, specifically, obtains the keyword information of the non-standard code stream by observing the information printed in the log, and further modifies the code correspondingly, wherein the modification method is to search all keyword fields in the code stream, and after finding out the keyword meeting the requirement, the keyword is taken as a parameter for calculating daylight saving time to calculate.
Based on the above implementation principle, the time display method in the display device provided by this example will be described in detail below. A daylight saving time setting interface diagram of the display device 200 by configuration of the control apparatus 100 is exemplarily shown in fig. 5. As shown in fig. 5, in the setting interface 201 when the user controls the display apparatus 200 to enter daylight savings by operating the control device 100, there are 3 modes in the interface, which are: forced Off mode (Off), forced On mode (On), and codestream Sync mode (Sync from DTV).
The forced closing mode, namely the forced closing summer time mode, enables the time displayed on the television to be the same as the local winter time. The forced opening mode, namely the forced opening daylight saving time mode, enables the time displayed on the television to be faster than the local winter time by N min no matter which season or month the television is currently in, wherein N is an offset and can be set according to the requirements of laws and regulations of the location of the display equipment. The offset is the time difference between the daylight saving time and the normal time, the offset is greater than or equal to 0 minute, the unit of the offset is minute, and the unit of the offset can be other units such as hour and the like; for example, summer hours are 1 hour faster than winter hours in new zealand. And in the code stream synchronization mode, judging whether the daylight saving time is displayed currently according to the information contained in the code stream.
When the user selects the code stream synchronization mode by operating the control device 100, or the display device 200 is configured as the code stream synchronization mode by default, the present embodiment enables the display device 200 to display the correct time by configuring it. It should be noted that the non-standard code stream in this embodiment refers to a code stream in the new zealand country or a code stream that has the same code mode as the code stream in the new zealand in terms of daylight savings time setting.
Comparing a time zone difference value (tz _ provision) corresponding to the area where the display equipment is located with a first time offset value (local _ time _ offset) in the TOT table, if the difference between the time zone difference value (tz _ provision) and the first time offset value (local _ time _ offset) is 1 hour, proving that the area where the display equipment is located executes a daylight savings time system, and then adding the first time offset value and UTC time to obtain target display time; if the two are not different, the area where the display device is located is proved not to execute the daylight saving time system, and the time of the display device is displayed as the normally calculated time.
A schematic view of the display interface of the display device 200 before it is configured is exemplarily shown in fig. 6a and 6 b. As shown in fig. 6a and 6b, it is assumed that the display apparatus 200 is applied to a new zealand country, and the received codestream is a new zealand codestream, i.e., a non-standard codestream. Before the display device 200 is configured, since it determines the daylight saving time according to the standard code stream, that is, determines whether the first time offset value (local _ time _ offset) and the second time offset value (next _ time _ offset) are the same, if the time of the area where the display device is located is in the daylight saving time period, the display device 200 cannot recognize that the area where the display device is located does not execute the daylight saving time, and thus the display time is the time of the area where the display device is located that is directly calculated.
Therefore, in the channel information user interface in fig. 6a, a display time column 202, a name 204 of the current channel, and at least two pieces of program information 203 provided are provided in the interface, but an error time that is not displayed in the daylight savings time system is still displayed in the display time column 202; similarly, in the EPG user interface (Electronic Program Guide) in fig. 6b, a display time column 202 and a two-dimensional Program menu 205 arranged in the order of channels and Program playing times are provided, but the display time column 202 displays error times that are not displayed in the daylight saving time system.
A schematic view of the display interface of the display device 200 after it has been configured is exemplarily shown in fig. 7a and 7 b. As shown in fig. 7a and 7b, assuming that the display device 200 is applied to a new zealand country, and the received code stream is a new zealand code stream, i.e. a non-standard code stream, after the display device 200 is reconfigured, the display device 200 compares the time zone difference value (tz _ determination) corresponding to the area where the display device is located in the received code stream with the first time offset value (local _ time _ offset) in the TOT table, so that the display time field 202 in the channel information user interface and the display time field 202 in the EPG user interface are the correct time displayed according to the daylight savings time system, i.e. 03:58PM in fig. 6a and 6b is changed to 04:58PM in fig. 7a and 7 b.
Based on the above description, in order to enable the display device to automatically and correctly display the time when the code stream received by the display device is the non-standard code stream and the region where the display device is located executes the daylight saving time system, the embodiment provides a time display method in the display device. Fig. 8 is a basic flowchart illustrating a time display method in a display device. As shown in fig. 8, the method specifically includes the following steps:
s101: and responding to an instruction for indicating to display the EPG user interface or the channel information user interface, and judging whether the first time offset value is the same as a time zone difference value corresponding to the area where the display equipment is positioned.
Wherein, the first time offset value (local _ time _ offset) refers to the time offset value of the current time system corresponding to the area where the display device is located, which is obtained from the code stream in the digital broadcast signal, and the time offset value is the difference between the local time of the current time system and the UTC time
When it is determined that the time zone difference value corresponding to the area where the display device is located is different from the first time offset value, it indicates that the area where the display device is located is within the summer time period, and step S102 is performed; otherwise, it indicates that the area where the display device is located is not in the daylight saving time period, and then step S103 is executed.
S102: and adding the first time deviation value and the UTC time to obtain target display time.
For example, the local _ time _ offset is converted to hours, and the value is 13 hours, i.e. 12+1 hour, where 12 is because new zealand is located in the 12-east region, so the difference between the time corresponding to the winter time of new zealand and the UTC time is 12 hours, then at this time, the current tv display time is the offset of the local winter time +1 hour, or the time calculated by UTC time + local _ time _ offset is the target display time, i.e. the daylight saving time.
S103: and adding the UTC time and the time zone difference value to obtain target display time.
the tz _ provision represents the time zone difference, determines the time zone in which the display device is located, and then, by using the UTC time plus the time zone difference in the TDT table, the time of the area in which the display device 200 is located, that is, the time of the area in which the display device 200 is located is the UTC time + time zone difference, for example, the UTC time is now 10:00, the time zone is east 12 area of new zealand (GMT +12:00), and the current time of the area in which the display device is located is 22: 00. Of course, the target display time of the display device may be calculated in other manners, such as using local _ time _ offset and UTC time.
S104: displaying an EPG user interface or a channel information user interface containing the target display time on a display.
Wherein if the received instruction is an instruction to display an EPG user interface, displaying the EPG user interface including the target display time on the display; and if the received instruction is an instruction for indicating the display of the channel information user interface, displaying the channel information user interface containing the target display time on the display.
Therefore, when the code stream received by the display equipment is a new Zealand code stream and a non-standard code stream of the code stream with the same coding mode as the new Zealand code stream, the correct daylight saving time can be displayed when the area where the display equipment is located is in the daylight saving time, and further, the correct time can be displayed on an EPG user interface or a channel information user interface of the display equipment at any time in the area.
Further, the embodiment also provides a time display method in the display device, which aims at that the code stream received by the display device may also be a standard code stream. Fig. 9 is a basic flow chart illustrating a time display method in another display device. As shown in fig. 9, the method specifically includes the following steps:
s201: in response to an instruction to instruct display of an EPG user interface or a channel information user interface, it is determined whether the first time offset value and the second time offset value are the same.
The second time offset value (next _ time _ offset) is a time offset value in the next time corresponding to the area where the display device is located, which is obtained from the code stream in the digital broadcast signal, and the time offset value is also a difference between the local time in the next time and the UTC time. If the second time offset value (next _ time _ offset) is different from the first time offset value (local _ time _ offset) local _ time _ offset, it indicates that the code stream received by the display device is a standard code stream, and the area where the display device is located executes the daylight saving time system, and then step S202 is performed, otherwise, it indicates that the code stream received by the display device is a non-standard code stream, or the received code stream is a standard code stream, but the area does not execute the daylight saving time system, and then step S203 is performed.
S202: and adding the first time deviation value and the UTC time to obtain target display time.
Of course, as for the display method of the target display time, the following manner may also be adopted: and judging whether the time of the area where the display equipment is located is in the summer time period or not according to the calculated time of the area where the display equipment is located and the start time and the end time of the summer time of the area where the display equipment is located. If the time of the area where the display equipment is located is within the summer time period, adding a preset offset to the time of the area where the display equipment is located to serve as target display time of the display equipment; and if not, taking the time of the area where the display equipment is positioned as the target display time of the display equipment. But the display time calculation process is more complicated than the way of adding the first time offset value to the UTC time.
S203: and judging whether the first time deviation value is the same as the time zone difference value corresponding to the area where the display equipment is located.
When it is determined that the time zone difference value corresponding to the area where the display device is located is different from the first time offset value, it indicates that the area where the display device is located is within the summer time period, and step S204 is performed; otherwise, it indicates that the area where the display device is located is not in the daylight saving time period, and then step S205 is executed.
And S204, adding the first time deviation value and the UTC time to obtain target display time.
S205: and adding the UTC time and the time zone difference value to obtain target display time.
S206: displaying an EPG user interface or a channel information user interface containing the target display time on a display.
According to the embodiment of the application, by analyzing the next _ time _ offset, the local _ time _ offset, the tz _ provision and the local _ time _ offset in the code stream received by the display device, not only can the received code stream be a standard code stream, but also the correct time can be displayed at any time all year round when the received code stream is a nonstandard code stream, such as a New Zealand code stream and a code stream having the same coding mode as the New Zealand code stream, so that the user experience can be improved.
