Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with embodiments of the invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of embodiments of the invention, as detailed in the following claims.
Fig. 1 is a flow chart illustrating a channel switching method, as shown in fig. 1, for use in a television set, according to an exemplary embodiment, the method including the following steps.
In step S101, when a channel switching signal is received, a time period of a current time of the television is obtained;
in the embodiment of the present invention, the channel switching signal includes a control signal that continuously controls a channel switching key on the television, and the time length of the channel switching key is longer than a preset time length.
The channels that can be played on the screen of the television include a set of channels, such as a set of channels at the center, and tens or hundreds of channels in each province and city, when a user needs to switch the channels played on the screen of the television, the user can continuously press the channel switching key on the television, and when the television detects that the user presses the channel switching key and continuously presses the channel switching key for a long time and a preset time, the channel switching signal is determined to be received.
The preset time period may be 1 second, 2 seconds, 3 seconds, and the like, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the television divides the time in the history process into a plurality of continuous time intervals, each time interval comprises a plurality of continuous time periods, and the time lengths of any two time periods are the same; the number of time periods included in any two time intervals is the same.
For example, one time interval is 24 hours per day, and one hour is one time period in one time interval, that is, assuming that 0 to 24 points of 2016, 10, 16 days are one time interval, 0 to 1 point of 2016, … … 23 to 24 points of 2016, 16 days are one time period for 24 time periods. Each day includes 24 time periods.
For any one time interval, the time period identifications of any two time periods included in the time interval are different. For example, the time period identification of the time period 0 point to 1 point may be "0001", the time period identification of the time period 12 point to 13 point may be "1213", and the time period identification of the time period 22 point to 23 point may be "2223", and so on.
The same time period exists in any two time intervals, and the same time period in any two time intervals identifies the same time period for the time period.
The time period of 0 to 1 point on day 10, 16 in 2016 is the same as the time period of 0 to 1 point on day 17 in 10 and 10 in 2016, and the time period of 1 to 2 points on day 16 in 10 and 10 in 2016 is the same as the time period of 1 to 2 points on day 17 in 10 and 10 in 2016, and so on.
In step S102, a play duration list corresponding to the time period is acquired; the playing time length list stores channel identifications of a plurality of channels; the channel identifications are arranged according to the sequence of the total playing duration of the channels in all the time periods in the history process from long to short;
in the embodiment of the present invention, the plurality of channels are all channels that can be played on the screen of the television. For example, for any one time period, the television may obtain a total playing time length for the television to play each of the multiple channels on a screen of the television in all the time periods in the history process; and then arranging the channel identifications of the plurality of channels according to the sequence of the counted total playing time length from long to short, and storing the channel identifications in a playing time length list corresponding to the time period.
The above operation is also performed for each of the other time periods, so that the play time length list corresponding to each time period can be obtained.
For example, assuming that the history process is 10 days in the past, for the time periods 4 to 5, since each day in the past 10 days includes the time periods 4 to 5, for any channel, the television may count the playing time of the channel played on the screen by the television between the time periods 4 to 5 on the first day, count the playing time … … of the channel played on the screen by the television between the time periods 4 to 5 on the second day until the playing time of the channel played on the screen by the television between the time periods 4 to 5 on the tenth day is counted, and then sum the counted 10 playing time to obtain the total playing time of the channel played between the time periods 4 to 5 in the past 10 days.
In the embodiment of the present invention, the identifier of the play duration list corresponding to a certain time period may be a time period identifier of the time period. The time period identification of each time period in one time interval is different, for example, the time period identification of 0 to 1 point of the time period may be "0001", the time period identification of 12 to 13 points of the time period may be "1213", and the time period identification of 22 to 23 points of the time period may be "2223", and so on. Therefore, the identification of the play time length list corresponding to different time periods is different. In this step, when the play duration list corresponding to the time period is acquired, the play duration list identified as the time period identification of the time period may be acquired and used as the play duration list corresponding to the time period.
In step S103, switching the channels played on the screen of the television according to the order of the channel identifiers stored in the channel playing time length list;
in the embodiment of the present invention, a channel played on a screen of a television may be first switched from a currently played channel to a channel corresponding to a first channel identifier in the play duration list, then the channel played on the screen of the television is switched from the channel corresponding to the first channel identifier in the play duration list to a channel corresponding to a second channel identifier in the play duration list, and then the channel played on the screen of the television is switched from the channel corresponding to the second channel identifier in the play duration list to a channel corresponding to a third channel identifier in the play duration list, and so on.
In step S104, in response to no channel switching signal input or in response to receiving a channel confirmation signal, a channel played on the screen of the television is controlled to stop switching.
In the process of switching the channels played on the screen of the television, when a certain channel to which the television is switched is a channel that the user wants to watch, the user may stop inputting the channel switching input signal in the television, for example, the user may stop pressing a channel switching key on the television, so that the television does not receive the pressing operation of pressing the channel switching key, and further determines that the channel switching input signal is not received, at this time, the channel played on the screen of the television may be controlled to stop switching, and then the television may play the channel that the user thinks to watch on the screen.
Or, in the process of switching the channels played on the screen of the television, when a certain channel to which the television is switched is a channel that the user wants to watch, the user may press a channel confirmation key on the television, and when the television detects a pressing operation of the user pressing the channel confirmation key, it is determined that a channel confirmation signal is received, and then the channel played on the screen of the television is controlled to stop switching, and then the television plays the channel that the user thinks to watch on the screen.
In the embodiment of the present invention, in general, a user may watch a specific program in a specific time period, for example, the user may watch a news simulcast program of a central set between 19 o 'clock and 19 o' clock 30 minutes in the past almost every day, and the user may very probably watch the news simulcast program of the central set between 19 o 'clock and 19 o' clock 30 minutes today.
Therefore, for any time slot, the television can acquire the total playing time length of each of the multiple channels played by the television on the screen in all the time slots in the history process; and then arranging the channel identifications of the plurality of channels according to the sequence of the counted total playing time length from long to short, and storing the channel identifications in a playing time length list corresponding to the time period.
In the embodiment of the present invention, when a channel switching signal is received, for example, when a pressing operation that a user presses a channel switching key on a television is received, the television can determine that the user needs to switch a channel played on a screen of the television, and at this time, the television can obtain a time period in which the current time of the television is located; then acquiring a play duration list corresponding to the time period; the playing time length list stores channel identification marks of a plurality of channels; the channel identification marks are arranged according to the sequence of the total playing duration of the channels in all the time periods in the history process from long to short; then, switching the channels played on the screen of the television according to the sequence of the channel identifier arrangement stored in the channel playing time length list; until the channel played on the screen of the television is controlled to stop switching in response to no channel switching signal input or in response to receiving a channel confirmation signal.
By the method of the embodiment of the invention, when a user wants to watch a channel which the user wants to watch on a television, the user does not need to continuously click the channel increasing key or the channel decreasing key for many times, and only needs to input a channel switching signal once in the television, so that troubles are avoided for the user, user experience is improved, time consumption in the process of continuously clicking the channel increasing key or the channel decreasing key for many times is avoided, and channel switching efficiency is improved.
In the embodiment of the present invention, among the plurality of channels, there may be an unplayed channel whose total play duration in all the time periods in the history process is zero; that is, there are channels that have not been played by the television during all of the time periods in the history. For example, assuming the history is the past 10 days, for the time period 4 to 5 points, the seven central sets and eight central sets are not played on the screen of the television set between the time period 4 to 5 points each day in the past 10 days.
In the multiple channels, when there are many unplayed channels in all the time periods in the history process, at the end of the play duration list, there are channel identifiers of the multiple unplayed channels, and since the total play duration of the unplayed channels in all the time periods in the history process is zero, in the play duration list, the total play duration in all the time periods in the history process cannot be arranged in the order of the channel identifiers of the unplayed channels, and in general, in the play duration list, the order among the channel identifiers of the unplayed channels is randomly arranged.
However, in the process of switching channels played on the screen by the television, if the switched channels played on the screen are all channels that the user does not want to watch, the user does not stop inputting a channel switching signal or inputting a channel confirmation signal on the television, when the television switches the channels played on the screen of the television to the channels with the total playing time length being not zero in all the time periods in the history according to the sequence of the channel identifiers stored in the channel playing time length list, if a channel switching signal is input or a channel confirmation signal is not received, the television starts switching the channels played on the screen to the unplayed channels in all the time periods in the history, however, when the unplayed channels in all the time periods in the history are more, the tv set cannot determine to which unplayed channel the channel played on the screen of the tv set should be switched first, which results in low accuracy of channel switching.
Therefore, in the process of switching channels played on the screen by the television, when the television switches all channels with the total playing time length not equal to zero in all the time periods in the history process on the screen, in order to determine a channel which a user most probably wants to watch in the non-played channels as soon as possible and play the channel which the user most probably wants to watch on the screen of the television, the accuracy of switching the channels is further improved; in another embodiment of the present invention, referring to fig. 2, the method further comprises:
in step S201, in the plurality of channels, it is detected whether there is an unplayed channel with a total play duration of zero in all the time periods in the history process;
in step S102, "the television may obtain a total playing time length of each of the plurality of channels played on the screen by the television in all the time periods in the history process; and then, arranging the channel identifications of the channels according to the counted total playing time length in the sequence from long to short, storing the channel identifications in a playing time length list corresponding to the time period, judging whether the total playing time length with the value of zero exists in the obtained total playing time length, and determining the channel corresponding to the total playing time length with the value of zero as the unplayed channel when the total playing time length with the value of zero exists.
When there is an unplayed channel with a total playing time length of zero, in step S202, respectively obtaining a total playing time length of each unplayed channel in a history process;
in the embodiment of the invention, in the history process, for any channel, when the channel starts to be played on the screen of the television, the television can acquire the current time of the television and use the current time as the initial playing time for playing the channel, when the television stops playing the channel, the television can acquire the current time of the television again and use the current time as the ending playing time for playing the channel, and then the playing time for playing the channel on the screen of the television at this time is acquired according to the initial playing time and the ending playing time; and storing the channel identification of the channel and the playing time length in the corresponding relation between the locally stored channel identification and the playing time length. Therefore, in this step, the television may obtain a correspondence between the locally stored channel identifier and the playing time length, then search for all the playing time lengths corresponding to the channel identifier of the unplayed channel in the correspondence between the channel identifier and the playing time length, sum up all the searched playing time lengths to obtain a time length, and use the time length as the total playing time length of the unplayed channel in the history process. The same is true for each of the other channels.
And when the non-played channel with the total playing time length of zero does not exist, ending the process.
In step S203, the channel identifiers of the unplayed channels in the play duration list are reordered according to the obtained total play duration from long to short.
The embodiment of the invention switches the channels by playing the history record of the channels in the history process of the television, thereby improving the accuracy of switching the channels, so that when the television continues to play the channels on the screen after the channels played on the screen of the television are controlled to stop switching, the history record needs to be updated by using the channels continuously played on the screen by the television.
Since, in the embodiment of the present invention, the histories are play time length lists respectively corresponding to the respective time periods. Therefore, the playing duration lists respectively corresponding to the time periods need to be updated according to the channels continuously played by the television, so as to improve the accuracy of switching the channels later.
Referring to fig. 3, the method further comprises:
in step S301, after controlling the channel played on the screen of the television to stop switching, acquiring the play time of the target channel played on the screen of the television;
in the embodiment of the invention, after the channel played on the screen of the television is controlled to stop switching, the television plays the channel switched to last time on the screen, and the channel is recorded as the target channel.
And when the channel playing on the screen of the television is controlled to stop switching, the television needs to acquire the current time of the television and use the current time as the initial playing time of the target channel playing on the screen of the television. When the television switches the channel played on the screen of the television from the target channel to another channel, the television acquires the current time of the television again and takes the current time as the playing ending time of playing the target channel on the screen of the television. And taking the starting playing time and the ending playing time as the playing time of the target channel played on the screen of the television.
In step S302, determining a playing duration of the playing target channel in each time period according to the playing time;
since each time slot has a start time and an end time, it can be determined in which time slot the target channel is played according to the start playing time and the end playing time of playing the target channel on the screen of the television, and determine the playing time of playing the target channel in each time slot.
For example, assuming that the start play time of playing the target channel on the screen of the television is 13: 20 minutes and the end play time is 15: 20 minutes, the play time period for playing the target video between 13: 14 points in the time period is 40 minutes, the play time period for playing the target video between 14: 15 points in the time period is 60 minutes, and the play time period for playing the target video between 15: 16 points in the time period is 20 minutes.
In step S303, the play time length list respectively corresponding to each play time length is updated according to the determined play time length.
For any time slot, if the target channel is played on the screen of the television in the time slot, the television updates the total playing time length of the target channel played on the screen in all the time slots in the history process by using the playing time length of the target video played on the screen in the time slot; and then, rearranging the channel identifications in the playing time length list corresponding to the time period according to the sequence of the total playing time lengths of the statistical channels from long to short.
And for any time period, the operation is also executed, so that the playing time length list corresponding to each playing time length is updated according to the determined playing time length.
In an embodiment of the present invention, referring to fig. 4, the method further includes:
in step S401, when a channel played on a screen of a television starts to be switched from a first channel to a second channel, displaying a preset picture on the screen of the television;
in the embodiment of the present invention, when a certain channel is being played on the screen of the television, if the user does not want to watch the certain channel at this time but wants to watch other channels, the user may click a channel switching key, such as a numeric key, a channel up key, a channel down key, and the like, on the remote controller of the television, where the numeric key is used to switch to a specific channel, the channel up key is used to switch to a next channel of the certain channel, and the channel down key is used to switch to a previous channel of the certain channel.
Therefore, when the user clicks the channel switching key on the remote controller of the television, the television can determine the second channel which needs to be switched by the user according to the channel switching key clicked by the user, or determine the second channel which needs to be switched by the user according to the channel switching key clicked by the user and the certain channel, and then start to switch the channel played on the screen of the television from the first channel to the second channel.
In the embodiment of the present invention, a process of switching a channel played on a screen of a television from one channel to another channel takes a period of time, during which any one channel cannot be played on the screen of the television, and in general, the screen of the television may present a blue screen or a black screen, and so on, so that a user can only view the blue screen or the black screen and cannot see other content, and the user can only wait for the channel played by the television to be switched from one channel to another channel and then play another channel on the screen of the television, and the user can only view another channel, which results in low user experience.
In the embodiment of the present invention, the technician may store the preset picture locally in advance.
When the channel played by the television is switched from the first channel to the second channel, the preset picture can be displayed on the screen of the television, so that in the process of switching the channel played on the screen of the television from the first channel to the second channel, a user can watch the preset picture displayed on the screen of the television.
