Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First, technical terms related to the present invention are exemplified or explained as follows:
in the scheme, the frame image can be 1) video is decomposed according to a certain frame rate to obtain one picture which is uniformly distributed on a time sequence, and each picture is one frame image; 2) after each frame image is preprocessed through the content of the wireless distributed bracelet display array, a set of bracelet display instructions corresponding to the frame image is obtained, and the set is also called a frame image; 3) each line in the content preprocessing result file of the wireless distributed bracelet display array represents a set of all display instructions corresponding to the image at a certain time point, and after the set is subjected to data compression by the scheme, a wireless transmission data packet corresponding to the frame image at each time point is also called a frame image.
A pixel, which may be 1) a pixel in a frame image; 2) an ID of a display unit and a display color of the display unit.
Display instructions in the system for informing the receiving nodes with unique addressing of the display operation, for example, what color each ID node needs to display, if 16-bit address space is used, the ID addressing range is 0-65535, and if 8-bit color space is used, the color space range is 0-255.
MTU, Maximum Transmission Unit (MTU), refers to the Maximum packet size (in bytes) that can be passed over a layer of a communication protocol.
The core idea of the scheme is that in the process of issuing the image data display instruction, according to whether the IDs of the display units controlled by the display instruction are continuous and/or whether the display colors are consistent, the display instruction corresponding to a complete image is compressed into one or more composite instructions, and the composite instructions are broadcasted, so that the display unit monitors and executes the display instruction of the display unit. The scheme can reduce the data transmission quantity and improve the data transmission efficiency.
Fig. 1 is a schematic diagram of an image data transmission logic according to an embodiment of the present invention, and as shown in fig. 1, the image data transmission process according to the embodiment of the present invention mainly includes three parts, namely, an acquisition part, a compression part, and a broadcast part of a display instruction.
Firstly, the acquisition of a display instruction, that is, the acquisition of a display instruction set of image data, the display instruction may be used to control a specific display operation of a display unit, where the display instruction includes ID information and display color information of the display unit, and a plurality of display units may form a display array, and the display array may display a complete image data. In addition, the image data displayed on the display array may also be a differential image, that is, image differential operation is performed on two adjacent frames of image data in the video data, so as to obtain a differential image of the two adjacent frames, and pixels in the differential image are included in the next frame of image data and are not included in the previous frame of image data, so that when two adjacent frames of image data in the video are transmitted, when the next frame of image data is transmitted, it is not necessary to transmit a display instruction corresponding to the entire image, but only needs to perform subsequent compression and broadcast operations on the display instruction of the differential image data, and meanwhile, the display unit can play the next frame of image data only by executing the display instruction corresponding to the differential image data, so that the processing and transmission amount of data can be greatly reduced.
Then, the display instructions in the display instruction set are compressed, and specifically, the compression may be performed according to two determination conditions, that is, whether the IDs of the display units corresponding to each display instruction are continuous and whether the display colors included in each display instruction are the same, to obtain one or more composite instructions, where the composite instruction is one instruction that is obtained by compressing the plurality of display instructions and is used for controlling the plurality of display units. As shown in fig. 1, in the compression process of the display instruction, the instruction compression may be performed according to a plurality of rules, for example, the display instruction with continuous ID and same display color of the display unit is compressed into a composite instruction, or the display instruction with discontinuous ID and same display color of the display unit is compressed into a composite instruction, or the display instruction with continuous ID and different color of the display unit is compressed into a composite instruction, or the display instruction with discontinuous ID and different color of the display unit is compressed into a composite instruction based on the above instruction compression method, where all the instruction compression methods may be implemented separately or in combination.
Finally, as shown in fig. 1, the composite command obtained by compressing the display command is packaged and stored, and broadcast at a specified time (for example, image playing time) so that the display unit monitors and executes the display command of the display unit, thereby displaying the image data.
Based on the schematic diagram of the image data transmission logic shown in fig. 1, as shown in fig. 2, it is a structural diagram of an image data transmission system according to an embodiment of the present invention, and is configured to specifically execute the image data transmission method provided in the embodiment of the present invention, where the system includes: a server 210 and a display array 220. The server 210 may specifically include:
the instruction acquisition module is used for acquiring a display instruction set for displaying the image data on the display array, each display instruction comprises an ID (identity) and a display color of a display unit, the display array 220 comprises a plurality of display units, and the IDs of the display units are continuous;
the instruction compression module is used for compressing the display instructions in the display instruction set according to the continuity of the IDs of the display units and/or the consistency of the display colors to obtain at least one composite instruction, and each composite instruction is used for controlling the display colors of at least two display units;
and the instruction broadcasting module is used for broadcasting the composite instruction corresponding to the display instruction set.
The display array 210 includes a plurality of display units, and each display unit is configured to monitor and execute a display instruction for the display unit.
The technical solution of the present application is further illustrated by the following examples.
Example one
Based on the above technical idea of image data transmission, as shown in fig. 3, which is a flowchart of a first image data transmission method according to an embodiment of the present invention, an execution subject of the method may be a server or an image transmission apparatus disposed in a network. As shown in fig. 3, the image data transmission method includes the steps of:
s310, acquiring a display instruction set for displaying the image data on a display array, wherein each display instruction comprises an ID and a display color of a display unit, the display array comprises a plurality of display units, and the IDs of the display units are continuous.
Wherein each display instruction is used for controlling the display operation of one display unit, for example, controlling the display color. The display instruction includes the ID and display color of the display unit to be controlled accordingly. The display unit is composed of devices capable of emitting light, a plurality of display units are arranged according to different positions to form a display array, and the shape of the display array can be, but is not limited to be, a rectangle. In order to integrally display the image data to be displayed on the display array, the image to be displayed may be mapped to the positions of the display units on the display array in advance, for example, one display unit may display one pixel in the image data, or a plurality of display units may display one pixel in the image data, or one display unit may generally display a plurality of pixels in the image data (pixel compression). Accordingly, the display instruction is used to control the display color of the display unit corresponding to each pixel point in the image data. For example, one display instruction may correspondingly control the display color of the display unit corresponding to one or more pixel points; or, the plurality of display instructions can also correspondingly control the display color of the display unit corresponding to one pixel point.
All display instructions required for displaying one piece of image data on the display array are referred to as a set of display instructions for the image data. In a display instruction set, the ID of a display unit to be controlled is continuously prepared.
S320, compressing the display instructions in the display instruction set according to the continuity of the IDs of the display units and/or the consistency of the display colors to obtain at least one composite instruction, wherein each composite instruction is used for controlling the display colors of at least two display units.
Specifically, all or part of the display instructions in the display set are compressed to generate a compound instruction, and the compression process can be performed continuously according to the IDs of the display units, for example, only the start ID and the end ID of a section of continuous ID values can be identified in the compound instruction, so that all the ID values from the start ID to the end ID can be replaced; or, the display unit may perform the process according to whether the display colors of the display units are the same, for example, only one color value may be identified in the composite instruction for the display instruction with the same color, and each ID value of the display unit corresponding to the color value is given.
In an actual application scenario, when the display instructions in the display instruction set are compressed according to the continuity of the IDs of the display units and/or the consistency of the display colors, based on the above idea, the display instructions with the same display color and the consecutive IDs of the plurality of display units may be compressed, the display instructions with different display colors and the consecutive IDs of the plurality of display units may be compressed, and the display instructions with the same display color and the discontinuous IDs of the plurality of display units may be compressed.
And compressing the plurality of display instructions to obtain a composite instruction, wherein the composite instruction can be used for controlling the display colors of the plurality of display units, and the content size of the composite instruction is reduced compared with the original discrete display instructions.
S330, broadcasting the composite instruction corresponding to the display instruction set so that the display unit monitors and executes the display instruction for the display unit.
Specifically, the display instruction is compressed and packed to form a compound instruction, and the compound instruction is broadcasted. After the display unit monitors the composite instruction, whether the composite instruction is specific to the display unit is analyzed, if the display unit ID in the composite instruction includes the ID of the display unit, if the display unit ID is analyzed, the display instruction of the display unit is executed, that is, the corresponding color is displayed according to the content of the display color of the display instruction. In the step, the composite command formed by compressing the display command is broadcasted, so that the data transmission quantity is greatly reduced.
Further, the display unit may specifically include: one or more wearable devices of a bracelet, a head band, a wrist band, a hair clip and a hat provided with the LED. These wearable devices can be placed on the surface of a person's body and then varied based on the person's position to form differently shaped display arrays, which are easy to operate while full of different shaped representations of image data.
Specifically, the display unit can be used for receiving the composite command sent by the base station and analyzing the display command corresponding to the composite command, and then controlling the LEDs to display corresponding colors and brightness.
In the image data transmission method provided by the invention, in the process of issuing the image data display instruction, according to whether the IDs of the display units controlled by the display instruction are continuous and/or whether the display colors are consistent, a plurality of display instructions are compressed into one or more composite instructions, and the composite instructions are broadcasted, so that the display units monitor and execute the display instructions of the display units.
