With the development of science and technology, the use of television sets is more and more widespread, and television programs are more and more colorful, and at present, the television programs become an important component in people's daily life. When using a television, one typically needs to control a device (e.g., a television or a set-top box) that receives a television program to search for channels and save the searched channels to watch the television program through the television terminal.
In the prior art, a user is usually required to manually input a corresponding symbol rate, and search is performed according to the symbol rate input by the user. Most users have difficulty knowing the required symbol rate explicitly and thus inputting the correct symbol rate. Therefore, the problem in the prior art is that the user needs to manually input the symbol rate during the channel searching, which is not beneficial to improving the channel searching efficiency, and meanwhile, the symbol rate input by the user is easy to make mistakes, which is not beneficial to improving the channel searching accuracy.
Currently, most devices for receiving television programs (e.g., televisions, set-top boxes, etc.) use the digital cable broadcast system standard (DVC-B, digital Video Broadcasting). DVB-C is used as a digital television system with wide application, has high use rate in radio and television operators at home and abroad, and frequency point tables, symbol rates and modulation modes used by different operators can be different. Therefore, in an application scenario, in order to adapt a device to be searched for a DVB-C function, such as a television, to different operators, a larger symbol rate range may be preset, where the range includes possible symbol rates of all operators, and searching for a channel according to the symbol rate range, for example, the symbol rate range, the frequency point table, and the modulation mode are issued to a tuner (tuner) to perform searching (channel scanning). But the process needs to sweep the platform and try to lock the frequency for a large range of symbol rate, and a large amount of searching time is needed to be consumed, so that the channel searching efficiency and the user experience are affected. After the tuner parameter is set, the signal can be locked at the frequency point, that is, the signal exists at the frequency point, and the television program can be received at the frequency point based on the corresponding symbol rate and modulation mode.
In order to solve at least one problem, the invention provides a channel searching method, when a searching mode of equipment to be searched is an automatic channel searching mode, a use area corresponding to the equipment to be searched is obtained; acquiring a target symbol rate range corresponding to the equipment to be searched based on the use area; and controlling the equipment to be searched to automatically search channels based on the target symbol rate range. Compared with the scheme that the channel searching is needed according to the symbol rate manually input by the user in the prior art, the method and the device have the advantages that the corresponding symbol rate does not need to be manually input by the user, and the target symbol rate range corresponding to the device to be searched can be automatically acquired according to the use area corresponding to the device to be searched, so that automatic channel searching is achieved. Therefore, the channel searching efficiency of the equipment to be searched is improved, channel searching errors or omission caused by error of the symbol rate input by the user can be avoided, accurate and comprehensive channel searching is realized, and channel searching accuracy is improved. And the user does not need to manually operate, thereby being beneficial to improving the use experience of the user and improving the applicability of the television and the set top box waiting for channel searching equipment.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a channel searching method, and specifically, the channel searching method includes the following steps:
Step S100, when the searching mode of the equipment to be searched is an automatic searching mode, the use area corresponding to the equipment to be searched is obtained.
The device to be searched is a device that needs to search for a program in a certain frequency range (for example, a preset frequency range). Optionally, the device to be searched may be a television, a projection device, a set-top box, or the like. It should be noted that, the above-mentioned device to be searched has a DVB-C function, and in this embodiment, a television set having a DVB-C function is specifically described as an example, but not as a specific limitation.
Specifically, different search modes, such as a manual search mode and an automatic search mode, can be selected or set in the device to be searched. In the manual channel searching mode, one or more specific symbol rates are manually input by a user, and the television searches channels according to the symbol rates input by the user, but the process requires the user to know the symbol rates and input the symbol rates, so that the channel searching efficiency and accuracy are not improved, and the use experience of the user is influenced. In the automatic channel searching mode, the television can automatically acquire the corresponding symbol rate range without manually inputting data by a user, thereby being beneficial to improving channel searching efficiency and user experience.
It should be noted that, the device to be searched (for example, a television) may determine the corresponding use area according to its system information (for example, a set time zone, a language, etc.) and/or the area information stored in the system, or may acquire the corresponding use area through networking, or may have other manners of determining the use area (for example, determining the use area through a selection instruction of a user), which is not limited specifically herein.
In this embodiment, as shown in fig. 2, before the step S100, the method further includes the following steps:
And step A100, obtaining the channel searching symbol rate in the equipment to be searched.
And step A200, determining a search mode of the equipment to be searched based on the search symbol rate, wherein when the search symbol rate is out of a range of the preset universal automatic search symbol rate in the equipment to be searched, the search mode of the equipment to be searched is an automatic search mode.
The search symbol rate is a flag for determining a search mode, and other flags may be used in the actual use process, for example, a search mode flag may be preset in a system of a device to be searched, and when a user selects a corresponding search mode, a corresponding search mode flag value is set as a corresponding value of the mode. In this embodiment, the search symbol rate is directly used as a flag for determining the search mode, which is convenient to use.
Specifically, a general automatic channel searching symbol rate range is preset in the device to be searched, and the general automatic channel searching symbol rate range can meet the symbol rate requirements corresponding to all the use areas, namely, the general automatic channel searching symbol rate range covers the symbol rates corresponding to all the use areas. In this embodiment, the general automatic symbol rate range is 3600Ksym/s to 7000Ksym/s, so that all symbol rates required for covering the DVB-C function can be satisfied, and it should be noted that the general automatic symbol rate range can be set and adjusted according to actual requirements, which is not limited herein.
In an application scenario, when the user does not manually input the symbol rate, the search symbol rate is set to a preset symbol rate value by default, where the preset symbol rate value is outside the universal automatic symbol rate range, and in this embodiment, the preset symbol rate value is 0. In another application scenario, when the user manually inputs the symbol rate, the symbol rate manually input by the user is used as the channel searching symbol rate, at this time, if the channel searching symbol rate is out of the general automatic symbol rate range, it is indicated that the symbol rate input by the user is wrong, and according to the symbol rate, the channel searching cannot be performed normally, at this time, the automatic channel searching mode can be entered, so that the channel searching accuracy is improved, the user does not need to input the symbol rate repeatedly, and the channel searching efficiency is improved.
In another application scenario, the user can also directly select an automatic channel searching mode, so that the operation of the user is facilitated.
Step S200, obtaining a target symbol rate range corresponding to the equipment to be searched based on the use area.
Specifically, in this embodiment, symbol rate range information is stored in advance in the device to be searched, so as to store target symbol rate ranges corresponding to different usage areas.
In this embodiment, as shown in fig. 3, the step S200 specifically includes the following steps:
Step S201, obtaining symbol rate range information stored in advance in the device to be searched, where the symbol rate range information includes a plurality of regions and a region symbol rate range used by each region.
Step S202, searching in the symbol rate range information based on the use region, and obtaining a region symbol rate range corresponding to the use region in the symbol rate range information as the target symbol rate range.
Each of the region symbol rate ranges is within the general automatic search symbol rate range, i.e., each of the region symbol rate ranges is smaller than the general automatic search symbol rate range. Therefore, after the use area is acquired, a smaller area symbol rate range (namely a target symbol rate range) corresponding to the use area can be obtained, and a large-range (general automatic channel searching symbol rate range) channel searching is not needed, so that the channel searching range can be shortened, the channel searching time is shortened, and the channel searching efficiency is improved. For example, the preset general automatic symbol rate range is 3600Ksym/s to 7000Ksym/s, and the region symbol rate range corresponding to the southeast Asia country may be preset in the symbol rate range information to 6000Ksym/s to 7000Ksym/s, so that the corresponding search range may be narrowed. Note that, the respective symbol rate ranges corresponding to the present embodiment may be determined by defining the corresponding upper limit value and lower limit value.
It should be noted that, operators corresponding to television sets in different usage areas are different, and symbol rates used by different operators are different, so that a regional symbol rate range of one usage area needs to cover symbol rates corresponding to all possible operators in the usage area. In an application scenario, the information of the operator corresponding to the device to be searched may be determined based on the use area or networking, and a specific symbol rate corresponding to the operator may be obtained and the searching may be implemented.
In this embodiment, the usage area is a usage country corresponding to the device to be searched. In an embodiment, the usage area may also be a usage city, a region, etc. corresponding to the device to be searched, which is not limited herein specifically.
Specifically, the method further comprises the following steps: acquiring a symbol rate range information updating instruction input by a target object; and updating the symbol rate range information in the equipment to be searched based on the symbol rate range updating instruction.
Specifically, the target object is a user who operates the equipment to be searched, and the target object can be a common user or a staff member who debugs and maintains the equipment. In this embodiment, the symbol rate range information is preset and stored in a memory (e.g., an E2P memory) of a device (e.g., a television) to be searched, so that power failure is not lost. The user may modify and adjust the symbol rate range information through the menu option of the television according to the actual requirement, for example, the newly added area and the corresponding area symbol rate range, modify the area symbol rate range corresponding to a certain area, and the like, which is not limited herein.
And step S300, controlling the equipment to be searched to automatically search channels based on the target symbol rate range.
In this embodiment, when the corresponding target symbol rate range is acquired based on the usage area, automatic channel searching may be performed based on the target symbol rate range. In an application scenario, if a corresponding target symbol rate range is not acquired due to the fact that the symbol rate range information does not include a current use area or the current use area is not acquired, automatic channel searching can be performed based on the general automatic channel searching symbol rate range, so that the success rate and accuracy of channel searching are improved.
In this embodiment, as shown in fig. 4, the step S300 specifically includes the following steps:
Step S301, a channel searching parameter corresponding to the device to be searched is sent to a front-end device management module, wherein the channel searching parameter comprises a frequency range, a modulation mode and the target symbol rate range.
Step S302, controlling the tuner of the device to be searched by the front-end device management module to automatically search the channel based on the channel searching parameters
In one application scenario, the front-end device management module (FeDrv) is a module for controlling a front-end device (Frontend), which is a node device for controlling a tuner (tuner). The front-end equipment management module can control the tuner of the equipment to be searched through the front-end equipment.
It should be noted that, the front-end device management module may be one module in a television (to-be-searched device), or may be one module in a control device other than the television. When the front-end device management module is one of the control devices other than the television, the front-end device and the tuner of the television can be controlled by wireless communication. In this embodiment, the end device management module is a module in a television system.
Specifically, the frequency range is a frequency range in which the equipment to be searched needs to search channels, and the modulation mode is a modulation mode which needs to be used during channel searching. The frequency range and the modulation mode can be preset and adjusted according to actual requirements, in this embodiment, the frequency range is 50MHz to 858MHz, and the modulation modes include 32QAM, 64QAM, 128QAM and 256QAM.
In this embodiment, the tuner sequentially obtains the target symbol rate in the target symbol rate range based on a preset symbol rate interval, combines the target symbol rate with the modulation mode, automatically searches channels in the frequency range, and feeds back success information to the front-end device management module when the channel search is successful.
When the channel is automatically searched, each target symbol rate and each modulation mode are combined in sequence, then frequency locking (channel searching) is carried out in a corresponding frequency range, and if the frequency locking is successful (namely, a corresponding satellite program signal is searched), success information is fed back immediately. If all the target symbol rates are traversed and frequency locking is not successful, failure information is fed back, so that a user can acquire a channel searching result in time.
In one application scenario, each symbol rate in the target symbol rate range may also be regarded as a target symbol rate, i.e. the symbol rate interval is set to 1, so that each (integer) symbol rate in the target symbol rate range is traversed. Alternatively, the symbol rate interval may be set and adjusted according to actual requirements, for example, may be set to 10, which is not particularly limited herein.
As can be seen from the above, in this embodiment, when the search mode of the device to be searched is the automatic search mode, the usage area corresponding to the device to be searched is obtained; acquiring a target symbol rate range corresponding to the equipment to be searched based on the use area; and controlling the equipment to be searched to automatically search channels based on the target symbol rate range. Compared with the scheme that the channel searching is needed according to the manual input symbol rate of the user in the prior art, in the embodiment, the user does not need to manually input the corresponding symbol rate, and the target symbol rate range corresponding to the channel searching equipment can be automatically acquired according to the use area corresponding to the channel searching equipment, so that the automatic channel searching is realized. Therefore, the channel searching efficiency of the equipment to be searched is improved, channel searching errors or omission caused by error of the symbol rate input by the user can be avoided, accurate and comprehensive channel searching is realized, and channel searching accuracy is improved. And the user does not need to manually operate, thereby being beneficial to improving the use experience of the user and improving the applicability of the television and the set top box waiting for channel searching equipment.
Meanwhile, a general automatic channel searching symbol rate range is preset in the equipment to be searched, when a user inputs wrong symbol rate, automatic channel searching can be carried out according to the general automatic channel searching symbol rate range, and channel searching efficiency is improved. Furthermore, a corresponding target symbol rate range smaller than the general automatic channel searching symbol rate range can be obtained according to the use area, so that the symbol rate range to be considered in channel searching is reduced, the number of combinations of the target symbol rate, a modulation mode, frequency and the like is reduced, the channel searching efficiency is improved, the time required by channel searching is reduced, and the user experience is improved.
In this embodiment, the above-mentioned channel searching method is further described based on a specific application scenario. Fig. 5 is a schematic flow chart of automatic channel searching of a television set according to an embodiment of the present invention, as shown in fig. 5, after the television system is started, the television system may be started to obtain default data stored in E2P, for example, each area and its corresponding area symbol rate range, preset channel searching symbol rate, etc. It should be noted that, after the television system is started, an intermediate service may also be run. If the user modifies the values in E2P from the factory menu during the use of the television, the modified values are saved to E2P. When the user selects the function of triggering DVB-C automatic channel scanning (channel searching), a channel scanning list can be constructed through a channel scanning module in the television system. In an application scenario, the scan table list includes a search symbol rate (specifically, 0), a frequency range (for example, 55MHz to 858 MHz), a modulation mode, and a target symbol rate range (or target symbol rate) corresponding to a usage area. The scanning platform module transmits parameters in the scanning platform list to FeDrv one by one, and finally sets the parameters to a tuner driving interface, and frequency locking is carried out through a tuner. FeDrv polling the frequency locking result of the parameters set once within a specified time (preset polling time), and if the frequency locking is successful, immediately returning the result to FeDrv when the frequency locking is successful, wherein the tuner drive tries to lock the frequency from high to low within the target symbol rate range under the specified frequency and modulation mode within the timeout time. If the attempt to lock the frequency is unsuccessful in traversing the symbol rate range, a failure result is given to FeDrv. If the frequency locking result is successful, the tuner drive returns the accurate symbol rate to FeDrv, and after the channel list is built by the final channel scanning module, the accurate symbol rate is stored in a database (Datebase) and is related to channel information, so that programs of corresponding channels are received later, namely, quick frequency locking can be carried out according to the accurate symbol rate and other information during playing, and the viewing experience of a user is improved.
The interface to the tuner setting symbol rate range is added in this embodiment, so that the tuner can be driven to lock frequencies in the designated symbol rate range. As such, a target symbol rate range (e.g., a scan upper limit and a scan lower limit for a target symbol rate) is set before issuing the frequency-locking parameter to the tuner. And under the tuner driving protocol, if the channel searching symbol rate is 0, automatically searching channels by adopting an automatic symbol rate mode, constructing a target symbol rate range by using the scanning upper limit and the scanning lower limit of the symbol rate corresponding to the region, and combining the target symbol rate range, the frequency range and the modulation mode, thereby realizing automatic channel searching. The user does not need to care about the method calling process, and the default symbol rate upper limit value and the default symbol rate lower limit value are determined to be written into E2P before leaving the factory and can be modified through a factory menu. Meanwhile, according to the use area (such as the use country), the corresponding target symbol rate range can be further reduced, so that the combination of a modulation mode and the target symbol rate is reduced, and the frequency locking time of the sweeping station is shortened.
