The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The technical solution of the present embodiment is explained in detail below by taking the display device 100 as an example of a smart television, and referring to fig. 2, fig. 2 shows a schematic flow chart of a display blocking method according to an embodiment of the present invention. It should be noted that the method provided by the embodiment of the present invention is not limited by the specific sequence shown in fig. 2 and described below. The method comprises the following specific steps:
step S210, receiving a video signal sent by a source device.
In this embodiment, the source device may be electrically connected to the display device 100 through an HDMI cable to transmit a video signal to the display device 100, and the display device 100 analyzes image information or video information in the video signal to display or play the video signal. Alternatively, the source device may be, but is not limited to, a smart set-top box, a DVD, or the like. As a preferred embodiment, the source device may adopt an intelligent set-top box provided with an HDMI interface.
In addition, the display device 100 may also receive an audio signal sent by the source device at the same time to implement playing of audio data.
In this embodiment, the video signal includes a General Control Packet (GCP) for performing auxiliary Control on video information, image information, or audio information, and the General Control Packet stores a field of an identification value related to audio image blanking.
Step S220, detecting the general control packet in the video signal.
Specifically, if the type of the video signal sent by the source device changes, for example, the type of the video signal of the source device is switched from 1080P @60Hz to 2160P @60Hz, or the frame rate of the video signal is unchanged, but the color depth of the type of the video signal changes (for example, from 10bit to 12bit) in order to obtain a finer display effect. These signal changes all cause a change in a Transition Minimized Differential Signaling (TMDS) Clock (Clock) according to which the source device sends video information, audio information, and audio/video auxiliary control packets to the display device 100), and when the transition minimized Differential signal Clock changes, signal glitches change, which results in no effective transmission of video data or audio data, that is, the display device 100 does not receive effective video data or audio data, which results in the display device 100 in the prior art having the occurrence of conditions of disordered image display and spurious sound playing.
In this embodiment, in order to solve the above-mentioned problem that the display device 100 has the disordered image display and the spurious sound playing, the display device 100 may detect the general control packet in the video signal in real time when receiving the video signal, so as to determine in advance whether there is a potential signal glitch according to the detection result, the determination method please refer to step S230, and if it is detected that there is a flag value for blanking the sound image in the general control packet, the display device 100 is configured to enter a preset display image blocking mode, so as to block the display image of the display device 100.
In this embodiment, after each time a source device receives a request for a Video signal change (e.g., a Video signal type change, a color depth change, etc.), the source device sends a signal indicating a value of Audio Video Mute (AVMute) to the display device 100 before executing a function corresponding to the request. The indication value of the audio image blanking is a characterization signal in the data island period of the HDMI link of the source device, which may be used to characterize the blanking of audio and images on the display device 100. After receiving the representation signal, the display device 100 enters a preset display screen shielding mode according to the representation signal, so as to shield the disordered image to be displayed, and at this time, the preset display screen is displayed in front of the user instead of the disordered image. According to the design, the situation that the disordered images appear are shielded at the first time is guaranteed through the marking value of sound image blanking in the real-time monitoring general control packet, so that the disordered images are not exposed to a user, and the watching experience of the user is improved.
As an embodiment, the above-mentioned manner for configuring the display device 100 to enter the preset display screen shielding mode may be: configuring the display screen of the display device 100 as a preset image, and configuring the audio player as a preset playing state.
Specifically, the preset image may be preset, for example, it is a common practice of most tv manufacturers to set the preset image as a blue screen image, which is a phenomenon of "blue screen" common to tv sets. The blue screen image, although blocking the distracted image, has a poor viewing experience for the user. As a possible embodiment, the preset image may be set as an image with better visual experience, for example, the preset image may be set as a landscape image that is pleasing to the eye, as a vast starry image, or the like. In addition, the television manufacturer can set the preset image as an image of a television brand according to requirements, for example, "microcun television" can set the preset image as an image including "microcun" Logo.
Although the above-mentioned manner blocks the scrambled image, there is a case of playing noise at this time because the display device 100 does not receive valid audio data, which affects the user experience. In view of this, as an embodiment, the manner of configuring the audio player to the preset playing state may be: the audio player is configured to be in a mute state, namely the audio player cannot play any sound, so that the situation of playing noise is avoided; still alternatively, the audio player may be configured to play preset audio data, that is, although the display device 100 does not receive valid audio data, the preset audio data may be played to avoid the noise playing situation; or, the audio player may be configured to be in a preset playing state in decibels, that is, the sound played by the audio player is lower than the sound that can be heard by human ears, and at this time, although the noise is in the playing state, the noise cannot be heard by the user, which also ensures the user experience.
Further, after the display device 100 enters the preset display frame blocking mode, as an embodiment, please refer to fig. 3, the method may further include:
step S240, detecting the stability of the video signal received after the display device 100 enters the shielding mode.
Step S250, if it is detected that the video signal is stable, configuring the display device 100 to display the image data in the stabilized video signal, and play the audio data in the audio signal. Specifically, in this embodiment, when the display apparatus 100 is in a preset display screen blocking mode, the display apparatus 100 detects in real time whether a general control packet in a video signal sent by the source apparatus includes a signal indicating a sound image blanking cancellation (Clear AVMute), where the indicating value of the sound image blanking cancellation is a characterization signal in a data island period of an HDMI link of the source apparatus, specifically, the characterization signal is used to indicate that blanking of sound and images on the display apparatus 100 is cancelled, and after receiving the characterization signal, if the received video signal and audio signal are stable, the display apparatus 100 cancels the preset display screen blocking mode. At this time, the display device 100 enters a normal display screen playing mode, that is, image data in the video signal is displayed, and audio data in the audio signal is played.
The display device 100 may identify the received video signal by comparing a portion of the received video signal, for example, the display device 100 may continuously compare htotal or vtotal in the video signal, if a difference between two consecutive values of htotal or vtotal is smaller than a corresponding threshold, taking the htotal corresponding to 1920 × 1080p as an example, if the two consecutive values are 1950 and 1955, subtracting the two values to obtain an absolute value, if the absolute value is smaller than a preset threshold (for example, 6), the htotal is identified as stable, and if the htotal is within a preset value range, the display device 100 identifies that the video signal is stable. It should be noted that if the htotal or vtotal or other portion exceeds a predetermined threshold, the video signal is identified as unstable.
Further, referring to fig. 4, the method may further include:
step 260, if it is detected that the indication value of audio image blanking and the indication value of audio image blanking cancel do not exist in the general control packet, detecting the stability of the video signal.
Step S270, when the video signal is stable, configuring the display device 100 to display the image data in the video signal, and play the audio data in the audio signal.
Step S280, when the video signal is unstable, configuring the display device 100 to enter the preset display screen shielding mode.
In this embodiment, when it is detected that there is no indication value for blanking the sound image and no indication value for blanking the sound image in the general control packet, and at this time, the display device 100 is in a normal display and play mode, that is, is not in a preset display picture shielding mode, the display device 100 detects the stability of the received video signal in real time. If the received video signal is detected to be stable, the normal display playing mode is kept; if the received video signal is detected to be unstable, configuring the display device 100 to enter the preset display image shielding mode.
