Description

Technical Field

[0001] The present invention relates to the technical field of Soundbar light synchronization, and particularly relates to a method, device, equipment and medium for real-time synchronization of Soundbar lights and TV pictures. Background Art

[0002] A Soundbar is a long strip-shaped speaker that integrates speakers and power amplifiers of multiple channels in a single cabinet. It is a product in the audio family that combines traditional AV audio and digital technology. Each channel has an independent cavity to ensure isolation and separation. It is placed horizontally and is mainly used in combination with a flat-panel TV, capable of forming an integrated visual effect with the flat-panel TV. It eliminates the troubles of numerous traditional home theater speakers, complex wiring, and cumbersome space layout. The wiring is simple and the installation is easy. Designed according to the size of the LCD TV, its length is roughly equivalent to the width of the TV set, and the speaker volume is small, making it appear coordinated and beautiful when paired with a flat-panel TV. Soundbar products with technologies such as DTS, Dolby Digital, and Dolby Pro Logic II are more excellent in surround sound performance and sound quality, and also have functions such as Bluetooth and wireless surround.

[0003] With the continuous development of home entertainment devices, Soundbar speakers are widely welcomed due to their simple design and high-quality sound effects. However, while existing Soundbar speakers provide sound effects, they often lack synchronous interaction with the visual experience. The change in the color of the TV picture can directly affect the emotions and viewing experience of the audience. As an audio output device, if the Soundbar speaker can change synchronously with the color of the TV picture, it will greatly enhance the user's immersion.

[0004] The traditional Soundbar lighting system only supports preset lighting modes (such as single-color breathing lights, music rhythm), and cannot be linked with the TV picture content; however, third-party external lighting devices (such as Philips Hue) rely on the TV HDMI-CEC protocol, resulting in compatibility problems and high latency; existing solutions cannot accurately extract the main color of the picture, leading to a disconnection between the lighting color and the picture content. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to propose a real-time synchronization method, device, equipment and medium for Soundbar lighting and TV pictures. By detecting and obtaining the original frame rate and adaptively matching it, the hue extraction operation period of the Soundbar is dynamically adjusted, so as to ensure the synchronization of the main hue extraction. By using the vertical synchronization pulse (V-Sync) as the processing trigger signal, it is ensured that each color analysis is only carried out during the stable period of the picture, avoiding color misjudgment caused by picture tearing. By accurately converting the main hue extracted from the TV picture into the drive control signal of the Soundbar lighting system, the color deviation problem caused by the color gamut difference of the display device and the physical limitation of the LED is solved, realizing the high-fidelity mapping from "picture color" to "lighting rendering", and solving the problems in the prior art that it cannot be linked with TV content, cannot accurately extract the main hue, and the lighting color is disconnected from the picture content.

[0006] To solve the above technical problems, the embodiments of the present application provide a real-time synchronization method for Soundbar lighting and TV pictures, and adopt the following technical solutions, including:

[0013] Further, after the step 120, the step 100 further includes:

[0014] Step 130: Judge the matching analysis of the original frame rate;

[0015] Step 140: If the detection of the original frame rate fails, start the fault tolerance mechanism to dynamically estimate the original frame rate of the current TV video to obtain the second original frame rate of the TV video.

[0016] Further, the step 200 includes:

[0017] Step 210: Dynamically compensate and allocate the video buffer according to the original frame rate of the TV video;

[0018] Step 220: Attach a timestamp to each frame.

[0019] Further, after the step 220, the step 200 further includes:

[0020] Step 230: Obtain the regional saturation, the distance from the regional center to the center of the screen picture, and the regional proportion;

[0021] Step 240: Use the regional saturation, the distance from the regional center to the center of the screen picture, and the regional proportion to construct a regional weighting model;

[0022] Step 250: According to the timestamp, and use the regional weighting model to extract the dominant color.

[0023] Further, after the step 250, the step 200 further includes:

[0024] Step 260: Obtain the playback mode of the TV video according to the original frame rate;

[0025] Step 270: If it is the cinema mode, perform interpolation compensation on the currently extracted dominant color according to the front and back frames;

[0026] Step 280: If it is the game mode, predict the dominant color by analyzing the HUD color information of the game engine.

[0027] Further, the real-time synchronization method of the Soundbar light and the TV picture further includes:

[0028] Step 400: Perform time-domain filtering on the LED lights of the synchronized Soundbar;

[0029] Step 500: Perform gradient interpolation on the partitioned LED lights of the Soundbar.

[0031] A frame rate detection module is used to acquire television video in real time, detect a vertical synchronization pulse signal of the television video, and use the vertical synchronization pulse signal as a trigger signal to perform original frame rate detection on the television video;

[0050] In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0051] The purpose of the embodiments of this application is to propose a method, device, equipment and medium for real-time synchronization of Soundbar lights and TV pictures.

[0052] To solve the above technical problems, the embodiments of this application provide a method for real-time synchronization of Soundbar lights and TV pictures, adopting the following technical solutions, as Figure 1 , Figure 1 is a flowchart of an embodiment of a method for real-time synchronization of Soundbar lights and TV pictures of this application; it includes:

[0053] Step 100, obtain the TV video in real time, detect the vertical synchronization pulse signal of the TV video, and use the vertical pulse signal as the trigger signal to detect the original frame rate of the TV video.

[0054] In a preferred embodiment, as Figure 2 , Figure 2 is Figure 1 a flowchart of a specific implementation manner of S100 in

[0055] In this embodiment, the original frame rate of the video stream (such as 24 / 30 / 60 Hz) can be obtained by decoding using a video decoder (such as the VPU module of MediaTek MTK 9667).

[0056] It is also possible to parse the VIC (Video Identification Code) of the current video stream through the InfoFrame packet of the HDMI protocol, and then match the preset frame rate table (such as the CEA-861 standard).

[0057] In this embodiment, the first original frame rate is the original frame rate directly detected by parsing the TV video.

[0058] In a preferred embodiment, such as Figure 3 , Figure 3 is Figure 2 a flowchart of a specific embodiment after S120; after step 120, step 100 further includes: step 130, judging the matching and parsing of the original frame rate; step 140, if the original frame rate detection fails, starting a fault tolerance mechanism to dynamically estimate the original frame rate of the current TV video to obtain the second original frame rate of the TV video.

[0059] In this embodiment, in the case of direct parsing detection failure, the original frame rate is detected and obtained using equation (1):

[0060]

[0061] where V-Sync is triggered twice per frame in progressive scanning, and f estimated is the second original frame rate.

[0062] Step 200, perform adaptive matching on the original frame rate, extract the main color tone of the picture in the TV video according to the original frame rate and using the regional weighted algorithm, and synchronously obtain the main color tone of each frame.

[0063] In a preferred embodiment, such as Figure 4 , Figure 4 is Figure 1 a flowchart of a specific embodiment of S200; step 200 includes: step 210, dynamically compensate and allocate the video buffer according to the original frame rate of the TV video; step 220, attach a timestamp to each frame.

[0064] In this embodiment, the video frame buffer is dynamically allocated according to the frame rate. For low frame rates (≤30 Hz), 3 frames of cache are reserved for interpolation compensation (to prevent frame loss); for high frame rates (>30 Hz), 1 frame of cache + direct pass mode is enabled (to reduce latency).

[0065] Attach a timestamp (with a precision of 0.1 ms) to each frame. Subsequently, when extracting the dominant color and driving the LED lights, the timestamp can be matched with the current frame to perform delay compensation and ensure synchronization.

[0066] When performing delay compensation, use Equation (2):

[0067]

[0068] Among them, the meanings of the parameters in Equation (2) are shown in Table 1.

[0069] Table 1

[0070]

[0071] In a preferred embodiment, as Figure 5 , Figure 5 is Figure 4 a flowchart of a specific embodiment after S220; after step 220, step 200 further includes: step 230, obtaining the regional saturation, the distance from the regional center to the center of the screen image, and the regional proportion; step 240, constructing a regional weighted model using the regional saturation, the distance from the regional center to the center of the screen image, and the regional proportion; step 250, extracting the dominant color according to the timestamp and using the regional weighted model.

[0072] In this embodiment, the regional weighted model is as shown in Equation (3):

[0073]

[0074] Among them, W region represents the weight value of the current region, dimensionless (scalar), and the greater the weight, the more significant the influence of this region on the dominant color.

[0075] C saturation is the regional saturation (in the HSV space), A region is the regional area proportion, and D center is the normalized distance from the regional center to the center of the screen.

[0076] After regional weighting, perform the output of the dominant color:

[0077]

[0078] Among them, the meanings of the parameters in Equation (4) are shown in Table 2.

[0079] Table 2

[0080]

[0081] Furthermore, as Figure 6 ,Figure 6 Yes Figure 5 It is a flowchart of a specific implementation after S250; after step 250, step 200 further includes:

[0082] Step 260, obtain the playback mode of the TV video according to the original frame rate; Step 270, if it is the cinema mode, perform interpolation compensation on the currently extracted dominant color according to the front and rear frames; Step 280, if it is the game mode, predict the dominant color by analyzing the HUD color information of the game engine.

[0083] In this embodiment, cinema mode (24 / 30Hz): Enable the motion compensation algorithm, smooth the light transition through interpolation of front and rear frame color data. When performing interpolation compensation, use the light fade speed formula:

[0084]

[0085] where, μ gradient represents the light fade speed, ΔH represents the change amount of hue, the unit is degree (°), representing the color difference value of the dominant color between adjacent frames. For example, when transitioning from red (0°) to yellow (60°), then ΔH = 60°. Δt represents the time change amount, the unit is frame (Frame), representing the time interval between adjacent frames, usually determined by the video frame rate. For example, in a 60Hz video, Δt = 1 / 60 second ≈ 16.67ms.

[0086] Limitation conditions: Cinema mode (low frame rate scenario): Limit the hue change rate ≤ 10° / frame to ensure smooth light transition and avoid visual jumping. Game mode (high frame rate scenario): Allow faster hue changes (≤ 30° / frame) to match fast screen switching and reduce latency.

[0087] Principle and formula analysis of the motion compensation algorithm:

[0088] Motion Compensation is a technology that generates intermediate frames or compensates the picture through inter-frame motion estimation. The core goal is to reduce redundant information and improve smoothness.

[0089] Game mode (60 / 120Hz): Adopt the "predictive rendering" technology to predict the dominant color by analyzing the HUD color information of the game engine. Prediction algorithm:

[0090] H predicted = H current + α(H current - H predicted )(6),

[0091] where, the meanings of the parameters in formula (6) are shown in Table 3.

[0092] Table 3

[0093]

[0094]

[0095] The significance of formula (6) is as follows: Based on the hue difference between the current frame and the previous frame, predict the main color direction of the next frame to reduce the lighting delay at high frame rates.

[0096] Step 300: Obtain the conversion matrix, and use the conversion matrix to perform color gamut matching on the main color of the picture to obtain the actual color gamut of the LEDs of the Soundbar lighting, and map each color value in the actual color gamut of the LEDs to the LED drive signal to synchronously drive the LEDs of the Soundbar lighting.

[0097] In this embodiment, when extracting the main color, dynamic range compression (brightness adaptation): Adjust the color brightness (Value) according to the LED maximum brightness limit (such as 10% - 90% of the maximum brightness):

[0098]

[0099] When Y source >Y source_max , start tone mapping to retain high - light details.

[0100] Among them, Y source represents the original brightness value of the input image (unit: nit), usually extracted from the CIE XYZ color space, representing the absolute brightness of the current pixel.

[0101] Y source_max represents the maximum brightness value of the input image (unit: nit). For example, an HDR image may be as high as 10,000 nit and needs to be compressed to the dynamic range of the display device.

[0102] Y LED_max represents the maximum safe brightness value of the LED lighting system (unit: nit), which is determined by the hardware specifications. For example, the WS2812B LED strip is usually limited to below 500 nit.

[0103] Y LED_min represents the minimum displayable brightness value of the LED lighting system (unit: nit) to avoid the inability to present details in overly dark areas.

[0104] Adjust the color brightness (Value) according to the LED maximum brightness limit (such as 1000 nits), and map the picture brightness (Y value) to the safe operating range of the LED (such as 10% - 90% of the maximum brightness) to avoid LED over - exposure while retaining high - light details.

[0105] Further, such as Figure 7 , Figure 7 This is a flowchart of another embodiment of a method for real-time synchronization of soundbar lighting and TV screens according to the present application; Figure 8 This is a schematic diagram of the module structure of a non-invasive blood pressure measurement device of the present application; the real-time synchronization method of the soundbar light and the TV screen also includes:

[0106] Step 400: Perform time domain filtering on the LED lights of the synchronously linked soundbar; Step 500: Perform gradient interpolation on the partitioned LED lights of the soundbar.

[0107] In this embodiment, the gradual smoothing process (joint filtering in time and space domains) is as follows:

[0108] When performing time domain filtering, use formula (9):

[0109]

[0110] The meanings of the parameters in formula (9) are shown in Table 4.

[0111] Table 4

[0112]

[0113] After joint spatiotemporal filtering, the color differences between consecutive frames are limited to avoid sudden changes in the soundbar lighting display. By detecting the original frame rate and adaptively matching it, the soundbar's color extraction operation cycle is dynamically adjusted to ensure the synchronization of the main color extraction. By using the vertical synchronization pulse (V-Sync) as the processing trigger signal, it is ensured that each color analysis is only performed during the stable period of the picture, avoiding color misjudgment due to picture tearing. By accurately converting the main color extracted from the TV picture into the drive control signal of the soundbar lighting system, the color deviation problem caused by the color gamut difference of the display device and the physical limitations of the LED is solved, and a high-fidelity mapping from "picture color" to "light rendering" is achieved, solving the problems of the existing technology that cannot be linked with TV content, cannot accurately extract the main color tone, and the disconnection between the light color and the picture content.

[0114] To solve the above technical problems, an embodiment of the present application further provides a device 600 for real-time synchronization of soundbar lighting and television screens, which adopts the real-time synchronization method of soundbar lighting and television screens of the first aspect, including:

[0115] The frame rate detection module 601 is used to obtain the TV video in real time, detect the vertical synchronization pulse signal of the TV video, and use the vertical pulse signal as the trigger signal to perform the original frame rate detection on the TV video.

[0116] Connect the Soundbar to the associated TV through HDMI communication; synchronously parse the obtained TV video, and obtain the first original frame rate of the TV video by matching the preset frame rate table.

[0117] In this embodiment, the original frame rate of the video stream (such as 24 / 30 / 60Hz) can be obtained by decoding using a video decoder (such as the VPU module of MediaTek MTK 9667).

[0118] It is also possible to parse the VIC (Video Identification Code) of the current video stream through the InfoFrame packet of the HDMI protocol, and then match the preset frame rate table (such as the CEA-861 standard).

[0119] In this embodiment, the first original frame rate is the original frame rate directly detected by parsing the TV video. Judge the matching and parsing of the original frame rate; if the original frame rate detection fails, start the fault tolerance mechanism to dynamically estimate the original frame rate of the current TV video to obtain the second original frame rate of the TV video.

[0120] The main color extraction module 602 is used to perform adaptive matching on the original frame rate, extract the main color of the picture in the TV video according to the original frame rate and using the regional weighting algorithm, and synchronously obtain the main color of each frame of the picture.

[0121] Dynamically compensate and allocate the video buffer according to the original frame rate of the TV video; attach a timestamp to each frame. In this embodiment, the video frame buffer is dynamically allocated according to the frame rate: low frame rate (≤30Hz): reserve 3 frames of cache for interpolation compensation (to prevent frame loss), high frame rate (>30Hz): enable 1 frame of cache + direct pass mode (to reduce latency).

[0122] Attach a timestamp (with a precision of 0.1 ms) to each frame. Subsequently, when extracting the dominant color and driving the LED lights, the timestamp can be matched with the current frame for delay compensation to ensure synchronization. Obtain the regional saturation, the distance from the regional center to the center of the screen, and the regional proportion; construct a regional weighted model using the regional saturation, the distance from the regional center to the center of the screen, and the regional proportion; extract the dominant color according to the timestamp and using the regional weighted model. Obtain the playback mode of the TV video according to the original frame rate; if it is the cinema mode, perform interpolation compensation on the currently extracted dominant color according to the previous and next frames; if it is the game mode, predict the dominant color by parsing the HUD color information of the game engine. In this embodiment, for the cinema mode (24 / 30 Hz): Enable the motion compensation algorithm to smooth the light transition through interpolation of the color data of the previous and next frames. When performing interpolation compensation, use the light fade speed formula.

[0123] The synchronization driving module 603 is configured to obtain a conversion matrix, perform color gamut matching on the dominant color of the screen using the conversion matrix to obtain the actual color gamut of the LEDs of the Soundbar lights, and map each color value in the actual color gamut of the LEDs to an LED driving signal to synchronously drive the LEDs of the Soundbar lights.
