Embodiment 1

[0040] Embodiment 1 of the present invention provides a television early warning method. Such as figure 1 As shown, it is a schematic flow chart of the television early warning method provided in Embodiment 1 of the present invention, and the method includes the following steps:

[0041] S1, detecting whether an image sequence corresponding to the warning information to be processed is loaded in the received TV signal;

[0042] S2, when it is detected that the image sequence is loaded in the TV signal, analyze the warning information to be processed according to the image sequence;

[0043] S3. Perform early warning processing according to the analyzed early warning information.

[0044] In actual use, when public affairs departments or other departments need to issue early warning information through TV, for example, when an emergency or natural disaster occurs in a country or region, it is necessary to entrust the TV service provider to add a specific image sequence corres...

Embodiment 2

[0059] Embodiment 2 of the present invention also provides a TV early warning method. The television early warning method provided in this embodiment is a further limitation of the television early warning method in Embodiment 1, including steps S1, S2, S3, S11, S12, S121, and S122 in Embodiment 1, and further defines:

[0060] The number of the first matching sequence is at least two, and each of the first matching sequences corresponds to a kind of early warning information; the determination of the image sequence according to the N frames of images in step S122 is specifically to set the N frame images as the image sequence;

[0061] In step S2, when it is detected that the image sequence is loaded in the TV signal, parsing out the warning information to be processed according to the image sequence includes:

[0062] When detecting that the image sequence is loaded in the television signal, determine a first matching sequence that matches the first parameter value sequence...

Embodiment 3

[0066] Embodiment 3 of the present invention also provides a TV early warning method. The television early warning method provided in this embodiment is a further limitation of the television early warning method in Embodiment 1, including steps S1, S2, S3, S11, S12, S121, and S122 in Embodiment 1, and further defines:

[0067] The determination of the image sequence based on the N frames of images in step S122 is specifically determining that the image sequence is composed of the N frames of images and M frames of images spliced ​​after the N frames of images; M is a preset fixed value and N is less than M;

[0068] In step S2, when it is detected that the image sequence is loaded in the TV signal, the warning information to be processed is analyzed according to the image sequence, specifically: when it is detected that the TV signal is loaded with When the above image sequence is used, the warning information to be processed is analyzed according to the second parameter val...

Abstract

The embodiment of the invention provides a television early warning method, a television receiver and a computer readable storage medium. The method comprises the following steps of detecting whetherthe image sequence corresponding to the early warning information to be processed is loaded in a received television signal or not; when the condition that the image sequence is loaded in the television signal is detected, resolving the early warning information to be processed according to the image sequence; performing early warning processing according to the resolved early warning information.The television early warning method provided by the embodiment has the advantages that whether the specific image sequence is loaded in the television signal or not is detected; when the image sequence is detected, the early warning information is extracted from the image sequence; further, the early warning processing is performed; the whole method is executed by computer programs; the additionof early warning hardware devices is not needed; the cost is reduced; meanwhile, the realization mode of detecting the image sequence in the television signal is used, so that the type of the television receiver is not limited; the television early warning method can be applicable to a digital receiver and an analog receiver; the popularizing rate is high.

Description

technical field [0001] The invention relates to the field of television receivers, in particular to a television early warning method, a television receiver and a computer-readable storage medium. Background technique [0002] Along with the promotion of television receivers, more and more families watch television programs by television receivers. Due to the increasing number of TV users, public affairs departments have begun to issue some urgent or important announcements through the TV platform. For example, when emergencies or natural disasters occur in a country or region, early warning information needs to be issued to remind the public to take precautions. [0003] At present, there are two ways to use the TV platform to realize early warning: [0004] One is to add an early warning hardware device in the television receiver, and provide an early warning through the early warning hardware device. Although the purpose of early warning can be achieved in this way, th...
