Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
As described above, the instability and abnormality of signals during the signal transmission process cause the display screen of the terminal to be black or interrupted, thereby affecting the normal operation. Therefore, the embodiment of the invention provides a signal transmission method, a signal transmission device, electronic equipment and a storage medium. A signal transmission method, a signal transmission apparatus, an electronic device, and a storage medium according to embodiments of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings.
Fig. 1 is a flowchart of a signal transmission method according to an embodiment of the present invention. Referring to fig. 1, a signal transmission method according to an embodiment of the present invention includes the following steps:
step 101: generating an original image signal and a backup image signal based on an input signal;
step 102: judging whether the original image signal is abnormal or not in real time based on the backup image signal; and
step 103: and when the original image signal is judged to be abnormal, selectively outputting the original image signal, and when the original image signal is judged to be abnormal, selectively outputting the backup image signal.
In the embodiment of the present invention, it should be noted that after power is turned on, an original image signal and a backup image signal may be established based on a normal input signal, and then when an abnormal signal occurs subsequently, the original image signal may be abnormal, while the backup image signal may be relatively normal, and the input signal abnormality may be inferred by comparing a difference between the original image signal and the backup image signal, so that the backup image signal is displayed according to a determination result, and the abnormality of the display screen of the terminal display caused by the abnormal original image signal is prevented. Wherein the backup image signal is generated internally independently of the original image signal. This process will be described in detail below with reference to fig. 2.
In the embodiment of the present invention, it should be noted that after the backup image signal is successfully established, the original image signal and the backup image signal can be compared in real time. The backup image signal may serve as a comparison reference. When the original image signal and the backup image signal have deviation, the original image signal is abnormal, the backup image signal can be selected to be output, and when the original image signal and the backup image signal have no deviation, the original image signal can be selected to be output.
Specifically, when the original image signal is judged to be abnormal in real time based on the backup image signal, the original image signal and the backup image signal are compared to determine whether the similarity of the original image signal and the backup image signal is smaller than a second proportion; and determining that the original image signal is abnormal when the similarity between the original image signal and the backup image signal is smaller than a second ratio.
Fig. 2 is a detailed flowchart for generating an original image signal and a backup image signal based on an input signal according to an embodiment of the present invention. Referring to fig. 2, generating an original image signal and a backup image signal based on an input signal includes:
step 201: decoding the input signal to generate an original image signal and synchronization information;
step 202: generating a synchronization signal based on the synchronization information;
step 203: decoding the synchronization signal to generate a backup image signal;
step 204: comparing the original image signal and the backup image signal to determine whether the similarity of the backup image signal and the original image signal reaches a first ratio; and
step 205: when the similarity between the backup image signal and the original image signal does not reach the first ratio, repeating the step of generating a synchronous signal based on the synchronous information and the step of decoding the synchronous signal to generate the backup image signal until the similarity between the backup image signal and the original image signal is determined to reach the first ratio.
In this embodiment, it should be noted that after power-on, based on the normal input signal, the decoder may be used to decode the input signal to generate the original image signal and the synchronization information. The synchronization information may be used to generate a synchronization signal. Decoding the generated synchronization signal may generate a backup image signal. Since the input signal is a normal input signal and the generated original image signal is a normal image signal, comparing the backup image signal with the original image signal can determine whether the generated backup image signal satisfies the backup use requirement. For example, it is determined whether the similarity of the backup image signal to the original image signal reaches a first ratio. The first ratio may be set in advance. The first ratio may be determined to be adjustable according to the usage requirements of the signal transmission environment for the signal.
Specifically, when the similarity of the backup image signal to the original image signal reaches a first ratio, it is determined that the generated backup image signal has satisfied the use requirement. When the original image signal is abnormal, the backup image signal can be selected to be output. When the similarity between the backup image signal and the original image signal does not reach the first ratio, which indicates that the generated backup image signal does not meet the usage requirement, step 202 and step 203 are repeated, i.e. the synchronization signal is generated again based on the synchronization information, and the backup image signal is generated again based on the generated synchronization signal until the similarity between the generated backup image signal and the original image signal reaches the first ratio.
In this embodiment, it should be noted that the similarity may be understood as a similarity in a broad sense, and includes not only similarity on picture pixels, but also temporal synchronization, and may also include other parameters and indexes for image comparison in the art.
As described above, after power-on, based on a normal input signal, a backup image signal that can satisfy the use requirement can be established. Then, when the original image signal is abnormal due to various reasons such as signal abnormality or decoding error in the subsequent signal transmission process, the backup image signal can be output to the terminal display unit, thereby ensuring the stability of the signal transmission process.
In the embodiment of the present invention, it should be noted that, the signal transmission method provided in an embodiment of the present invention may further include: after power-on, performing quality evaluation on the input signal; and preprocessing the quality of the input signal based on the evaluation result. Evaluating the quality of the input signal may include scoring the input signal to characterize the quality of the input signal. The input signal is preprocessed based on the evaluation result. The pre-processing includes adjusting a waveform for an input signal.
In the embodiment of the present invention, it should be noted that, the signal transmission method provided in an embodiment of the present invention may further include: when the original image signal or the backup image signal is output, a reminder may be output at the same time. When the original image signal is not abnormal and the original image signal is selected to be output, the corresponding reminding information may be output at the same time, for example, the reminding information may be displayed as "normal state" or "poor quality" with reference to the evaluation result in step 301. When the original image signal is abnormal and the backup image signal is selected to be output, corresponding reminding information can be output at the same time, and the reminding information can be, for example, "abnormal state (switched to backup image)" and the like. The present invention does not limit the specific examples of the reminder information.
Fig. 3 is a specific flowchart for determining whether an original image signal is abnormal in real time based on a backup image signal according to an embodiment of the present invention. Referring to fig. 3, the real-time determination of whether an original image signal is abnormal based on a backup image signal specifically includes the following steps:
step 301: comparing the original image signal with the backup image signal to determine whether the similarity of the original image signal and the backup image signal is less than a second ratio; and
step 302: and when the similarity between the original image signal and the backup image signal is smaller than the second proportion, determining that the original image signal is abnormal.
In this embodiment, it should be noted that the second ratio may be adjusted based on the evaluation result of the input signal in the evaluation step. Specifically, when the score of the input signal is high, the second ratio may be set to a large value, and when the score of the input signal is low, the second ratio may be set to a small value, whereby whether the original image signal is abnormal or not may be determined more accurately.
