Illustratively, after selecting the DVB-C signal channel, a TV program searched based on the DVB-C signal channel is randomly played, and then the user can switch to the TV program of personal preference by a TV remote control.

Fig. 2 is a schematic flow chart of a method for switching television programs according to an embodiment of the present application. The method for switching a television program provided in this embodiment may be performed by a device for switching a television program, which may be implemented by software/hardware, and in this embodiment, the device may be a display device, such as a digital television. As shown in fig. 2, the method for switching television programs provided in the embodiment of the present application may include the following steps:

s101, receiving a video signal of a first television program through an input interface, and determining the playing state of the first television program.

The DTV signal source includes at least two signal channels, and the signal channels may be, for example, a DVB-C channel, a DVB-S channel, and a DTMB channel. The first television program may be any type of television program that is searched based on any signal channel, such as: news, entertainment, social education, tv play, etc., which are not limited in this embodiment.

The input interface is an interface between a video processor and a display of the display device, when a picture of a first television program is displayed on the display, the display can send a signal of the displayed picture to the video processor at regular time, and the video processor receives the video signal and compares the video signal with a preset video signal to determine the playing state of the first television channel. The playing state comprises a normal playing state and an abnormal playing state, the normal playing state is used for indicating that the signal of the television program is normal, the abnormal playing state is used for indicating that the signal of the television program is abnormal, and the normal signal abnormality at least comprises two conditions: e.g., no signal, toggling back and forth between the presence and absence of a signal.

For example, when the first television program is without a signal, a word "no signal" may be displayed on the television interface, fig. 3 is a schematic diagram of the television interface in the absence of a signal provided in an embodiment of the present application, as shown in fig. 3, a television channel name of the first television program may be displayed in an upper left corner of the television interface, for example, CCTV1 may be displayed, the word "no signal" is displayed in the middle of the television interface, and in addition, the word "no signal" may be bold and highlighted, and the word may also be displayed in a rolling manner, so as to remind a user that the playing state of the first television program is an abnormal playing state. Of course, the display mode of the word "no signal" includes, but is not limited to, the above modes, and this embodiment does not limit this.

S102, when the playing state of the first television program is the abnormal playing state, switching from the first television program to the target television program, and displaying the picture of the target television program.

The abnormal playing state of the tv program may be caused by weather, hardware, etc. In this embodiment, in order to avoid the problem of continuous waiting of the user in the prior art, when the playing state of the first television program is the abnormal playing state, the first television program is switched to the target television program, and the picture of the target television program is displayed, where the playing state of the target television program is the normal playing state.

Optionally, the method further includes:

and acquiring the time length of the first television program in the abnormal playing state, controlling the video processor to switch from the first television program to the target television program when the time length is longer than a first preset time length, and controlling the display to display the picture of the target television program.

Illustratively, the display device is internally provided with a timer, and when the first television program is abnormally played, the timer is started to count the time length of the first television program in the abnormal playing state. Or, according to the duration of the continuous display of the word "no signal" on the display device, the duration is the duration of the first television program in no signal.

The first preset time length is a critical time length, that is, the time length of the television program in the abnormal playing state is less than the first preset time length, which indicates that the television program may be only temporarily abnormal and can be recovered; the time length of the television program in the abnormal playing state is longer than the first preset time length, which indicates that the television program cannot be recovered in a short time.

In this embodiment, when the duration that the first television program is in the abnormal playing state is longer than a first preset duration, which indicates that the first television program cannot be recovered in a short time, the first television program is switched to the target television program, and when the duration that the first television program is in the abnormal playing state is shorter than the first preset duration, the user experience is not affected by frequent switching, and the television program is not switched.

It should be noted that the signal channel corresponding to the target television program and the signal channel corresponding to the first television program may be the same, such as DVB-C, or may be different, for example, the signal channel corresponding to the target television program is DVB-S, and the signal channel corresponding to the first television program is DVB-C, as long as the signal of the target television program is normal, which is not limited in this embodiment.

In addition, the abnormal playing state is used for indicating the signal abnormality of the television program, and the signal abnormality at least comprises two conditions: no signal, switching back and forth between presence and absence of a signal. Illustratively, the first preset time period may be, for example, 30s when the first television program is no signal, and may be, for example, 120s when the first television program switches between presence and absence of signals, because: the probability of the signal being recovered to be normal when the television program is switched back and forth between the presence and absence of the signal may be greater than the probability of the signal being recovered to be normal when the signal is absent, and therefore the first preset time duration set when the first television program is switched between the presence and absence of the signal may be greater than the first preset time duration set when the first television program is absent. The specific value of the first preset duration is not limited in this embodiment, and may be determined according to actual conditions.

The method for switching television programs provided by the embodiment comprises the following steps: the method comprises the steps of receiving a video signal of a first television program through an input interface, determining the playing state of the first television program, switching from the first television program to a target television program when the playing state of the first television program is an abnormal playing state, and displaying the picture of the target television program. Therefore, the normal television programs are switched and played when the television programs are abnormally played, the continuous waiting of the user is avoided, and the user experience is improved.
