Detailed Description
The following describes in detail specific embodiments of a method and an apparatus for controlling screen brightness of an intelligent home device according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a display method of a display device, as shown in fig. 1, which may include:
the display device may be, but is not limited to, a smart television, or a set-top box controlling a television to display.
S101, acquiring authentication information corresponding to an encrypted channel in a predetermined channel list;
the authentication information corresponding to the encrypted channel may be, but is not limited to, a group of encrypted character strings, and when the authentication information is obtained, a key that may indicate that the right to apply for decryption of the encrypted channel to the certificate server is available.
To explain this, when the display device is powered on again after being powered off, the authentication information corresponding to the encrypted channel may change; for example, if the authentication information corresponding to the encrypted channel with the serial number 1 after the first power-on is denoted by a, the authentication information corresponding to the encrypted channel with the serial number 1 after the second power-on may not be a, but b, so as to increase the security of the encrypted channel.
And when the authentication information is acquired, the authentication information can be acquired when the display device is started, so that the authentication information can be acquired in advance when the user switches channels. Of course, the authentication information may also be obtained after the display device is turned on for a period of time (e.g., t1), and t1 may be set as needed; as long as it is guaranteed as much as possible that the process of acquiring authentication information has already started to be performed before the user switches channels.
S102, when an instruction of a user for switching to an encrypted first channel is received and a preset condition is met, a key for decrypting the first channel is obtained; wherein the preset conditions include: determining that authentication information corresponding to the first channel is obtained;
specifically, taking the display device as a television as an example, when a user needs to switch to an encrypted channel of the television, the user can operate a key of a remote controller corresponding to the television, and can also operate according to a display interface on the television, thereby completing the switching of the channel.
It should be noted that the encrypted channels in the channel list correspond to the authentication information one to one.
Moreover, the process of acquiring the authentication information corresponding to the first channel (i.e. the first process) and the process of switching the encrypted first channel (which is referred to as the second process) are independent of each other, and do not affect each other.
Therefore, when the set-top box is started, the first process can be executed.
In practical situations, since the first process and the second process are independent from each other, when the set-top box is powered on, if the user starts the second process, that is, the user starts channel switching and switches to the first channel, at this time, for the first process, there may be the following situations:
1. the first process just starts to be executed, and authentication information corresponding to any encrypted channel is not acquired;
2. the first process is executed, and the authentication information corresponding to the partial encrypted channel in the channel list is acquired, but the authentication information corresponding to the first channel is not acquired;
3. the first process has already started to execute, and has acquired authentication information corresponding to a part of encrypted channels in the channel list, and has acquired authentication information corresponding to the first channel.
Therefore, the key is only obtained when the third condition is satisfied, that is, the authentication information corresponding to the first channel is obtained, and the key is not obtained when the first and second conditions are satisfied.
S103, after the first channel is decrypted according to the acquired key, the content of the first channel is displayed.
Specifically, when the key is obtained, the specific process may be:
sending a second request signal for decoding the first channel to a certificate server according to the currently acquired authentication information corresponding to the first channel, wherein the second request signal may carry the authentication information corresponding to the first channel and an identifier corresponding to the display device;
when receiving the second request signal, the certificate server sends a second feedback signal carrying a key for decrypting the first channel to the display device;
upon receiving the second feedback signal, the key is determined.
Therefore, the authentication information corresponding to the first channel is acquired before the encrypted first channel is switched, so that the time for acquiring the authentication information corresponding to the first channel is reduced when the channel is switched, and the problem of overlong time for switching to the first channel due to waiting for acquiring the authentication information corresponding to the first channel is solved, thereby improving the speed of switching the channel and improving the experience of a user.
In specific implementation, in the embodiment of the present invention, when an instruction for a user to switch to an encrypted first channel is received and a preset condition is not met, before acquiring a key for decrypting the first channel, the method further includes:
and acquiring authentication information corresponding to the first channel.
Therefore, when the preset condition is not met, that is, when the user needs to switch the first channel, the authentication information corresponding to the first channel is not acquired temporarily, so that before the key is acquired, the authentication information corresponding to the first channel needs to be acquired, which is beneficial to acquiring the key for decrypting the first channel according to the acquired authentication information corresponding to the first channel subsequently, so as to decrypt the first channel conveniently.
In a specific implementation, in the embodiment of the present invention, acquiring the authentication information corresponding to the first channel specifically includes:
judging whether a first request signal is sent to an authentication server at present, wherein the first request signal is used for requesting the authentication server to issue authentication information corresponding to a first channel;
if so, waiting for receiving a first feedback signal which is sent by the authentication server and carries authentication information corresponding to the first channel, and determining the authentication information corresponding to the first channel according to the received first feedback signal;
if not, sending a first request signal to the authentication server, waiting for receiving a first feedback signal which is sent by the authentication server and carries authentication information corresponding to the first channel, and determining the authentication information corresponding to the first channel according to the received first feedback signal.
The specific process of sending the first request signal to the authentication server and the specific process of sending the first feedback signal by the authentication server may be implemented by using the prior art, which is not limited herein.
It should be noted that, after the first request signal has been sent to the authentication server, the authentication server may be sending the first feedback signal, and at this time, it is only necessary to wait for receiving the first feedback signal sent by the authentication server without sending the first request signal to the authentication server.
Therefore, by the method, the first request signal is only required to be sent to the authentication server once, the problem that the first request signal is repeatedly sent to the authentication server is solved, the workload of the equipment is reduced, and the working efficiency of the display equipment is improved.
In specific implementation, in the embodiment of the present invention, acquiring the authentication information corresponding to the encrypted channel in the predetermined channel list specifically includes:
sequentially sending a first request signal to an authentication server according to at least one encrypted channel included in a predetermined channel list; the first request signal is used for requesting the authentication server to send authentication information corresponding to the encrypted channel;
sequentially receiving a first feedback signal which is sent by an authentication server and carries authentication information corresponding to an encrypted channel;
and according to the first feedback signals received in sequence, sequentially determining the authentication information corresponding to each encrypted channel.
When the channel list includes a plurality of encrypted channels, the number of the encrypted channels included in the channel list may be set according to the situation to meet the requirements of different scenarios, which is not limited herein.
For example, the channel list includes 2 encrypted channels, which are a first encrypted channel and a second encrypted channel, for example.
Firstly, sending a first request signal to an authentication server according to a first encryption channel;
and then the first request signal is sent to the authentication server according to the second encryption channel.
Alternatively, it may be:
firstly, sending a first request signal to an authentication server according to a second encryption channel;
and then a first request signal is sent to the authentication server according to the first encryption channel.
The request sequence is not particularly limited as long as the authentication server is sequentially requested for authentication information corresponding to each encrypted channel.
And, for the authentication server issuing the first feedback signal according to the first request signal, it may be before sending the first request signal to the authentication server according to the second encrypted channel;
or after the first request signal is sent to the authentication server according to the second encryption channel;
or, when the first request signal is being sent to the authentication server according to the second encrypted channel;
therefore, the method is not particularly limited, and needs to be determined according to actual conditions.
Therefore, the authentication information corresponding to the encrypted channel can be accurately determined by the method, and the determined authentication information corresponding to the encrypted channel is more accurate because only one first request signal is sent by the authentication server after each time of receiving.
In specific implementation, in the embodiment of the present invention, the channel list is a first list, and each channel included in the first list is an encrypted channel;
the method for determining the first list specifically comprises the following steps:
obtaining a second list comprising at least encrypted channels;
analyzing each channel included in the second list to determine an encrypted channel;
and recording the determined encrypted channels into a preset table, and determining the preset table in which the encrypted channels are recorded as a first list.
The method for determining the encrypted channel is not limited to the above parsing each channel included in the second list, and any method known to those skilled in the art that can determine the encrypted channel may be used, and is not limited herein.
Also, the determined encrypted channel may be, but is not limited to, recorded in a map table, that is, the first table may be, but is not limited to, a map table.
For example, taking a map table as an example, the structure of the map table can be seen in table 1, where the serial numbers of the channels in table 1 are 1, 2, and 3, respectively; the authentication information is denoted by a and b, respectively.
TABLE 1
| Channel number | Authentication information |
| 1 | Air conditioner |
| 2 | a |
| 3 | b |
Referring to table 1, if the first channel is a channel with sequence number 1 and the authentication information corresponding to the first channel is not currently acquired, the content of the location of the authentication information corresponding to the first channel with sequence number 1 in table 1 is empty;
if the first channel is the channel with the sequence number 2 and the authentication information (e.g., a) corresponding to the first channel is already currently acquired, the acquired authentication information a corresponding to the first channel may be written into the corresponding position in table 1.
Therefore, through the table, whether the authentication information corresponding to the first channel is acquired can be accurately and quickly determined, and when the authentication information corresponding to the first channel is determined to be acquired, the corresponding secret key can be directly acquired without spending time to acquire the authentication information corresponding to the first channel, so that the channel switching efficiency can be effectively improved, and the experience of a user is improved.
