TABLE 3 Table 3
Optionally, determining a target parameter combination from the at least one initial parameter combination based on the first parameter comprises: sequencing at least one initial parameter combination from big to small according to the sum of parameters in each initial parameter combination to obtain a first sequencing result; based on the first ranking result, an initial parameter combination with the smallest sum of parameters is determined as a target parameter combination.
In an alternative embodiment, the plurality of initial parameter combinations may be ranked from large to small according to the sum of parameters in each initial parameter combination, so as to obtain a first ranking result, so as to select an initial parameter combination in which the sum of parameters in the initial parameter combinations is closest to the first parameter, that is, an initial parameter combination in which the sum of parameters in the initial parameter combination is minimum, so that the capability of the receiving end for receiving the image data matches the capability of the transmitting end for transmitting the image data, other receiving ends with stronger receiving capability are not wasted, and specifically, the initial parameter combination in which the sum of parameters is minimum from the plurality of initial parameter combinations may be determined by the first ranking result, and the initial parameter combination is determined as the target parameter combination.

In an alternative embodiment, the plurality of initial parameter combinations may be ranked from large to small according to the number of parameters in each initial parameter combination, so as to obtain a second ranking result, so that the initial parameter combination with the smallest number of parameters in the initial parameter combinations is selected, so that the image data sent by the sending end is received by adopting the smallest number of receiving ends, and further the effect of saving resources of the receiving ends is achieved.
Optionally, determining the target transmission mode based on the target receiving end includes: acquiring a parameter proportion, wherein the parameter proportion is used for describing the proportion of parameters among a plurality of target receiving ends; and determining the target transmission mode based on the first parameter and the parameter proportion.
In an alternative embodiment, if there are multiple target receivers, the parameter ratio between the multiple target receivers may be determined. When two target receiving ends exist, the parameter proportion between the two target receiving ends can be obtained, and the mode of transmitting the image data by the transmitting end is determined based on the first parameter and the parameter proportion.
For example, the parameter of the transmitting end is 144, the parameter of the first target receiving end is 30, the parameter of the second target receiving end is 120, and it may be determined that the parameter ratio of the plurality of target receiving ends is 1:4, that is, when the first target receiving end processes 1 frame of image data, the second target receiving end may process 4 frames of image data, and it may be determined that the target transmission mode is that the number of frames sent by the transmitting end to the first target receiving end is: frame 1, frame 6 … …, 4n+1; wherein n is an integer greater than or equal to 0 and less than 36, and the number of frames sent by the sending terminal to the second target receiving terminal is: frames 2,3,4,5, 7,8,9,10, frame … …, 4n+2,4n+3,4n+4,4n+5, until the transmitting end transmits 144 frames.
In another alternative embodiment, when there are multiple target receiving ends with the same parameters, that is, when the decoding capacities of the multiple target receiving ends are the same, one frame of image data may be sent to each target receiving end in the order of the multiple target receiving ends, and when the frame cannot be divided, the last round of the frame is completed to which target receiving end.
For example, the parameter of the transmitting end is 144, five target receiving ends are shared, the parameter of each target receiving end is 30, at this time, polling can be performed in the order of decoding one frame by each decoding end of 5 frames in order, when the polling cannot be completed, which target receiving end is the round to end from which target receiving end, and the image data is transmitted in the polling mode, so that not only can the problem of insufficient frame rate of the receiving end be solved, but also the delay can be reduced.
A preferred embodiment of the present application will be described in detail with reference to fig. 2 to 3. As shown in fig. 2, the method may include the steps of:
step S201, the source end identifies the frame rate of the original image and transmits the original image to the transmitting end matched with the frame rate;
fig. 3 is a schematic diagram of a transmission system of image data. Wherein the source may be a computer device. The source end and the transmitting end may be connected by using a high-definition multimedia interface (High Definition Multimedia Interface, abbreviated as HDMI), and may also be connected by using a universal serial bus (Universal Serial Bus, abbreviated as USB).
Step S202, a transmitting end encodes an original image to obtain image data;
step S203, obtaining the frame rate of a transmitting end and the frame rates of a plurality of receiving ends;
the plurality of receiving terminals are used for receiving and decoding the image data sent by the sending terminal.
Step S204, the transmitting terminal determines a target receiving terminal from a plurality of receiving terminals according to the frame rate of the transmitting terminal and the frame rates of the plurality of receiving terminals;
in step S205, the transmitting end determines a target transmission mode according to the target receiving end, and transmits the image data by using the target transmission mode.
The sending terminal sends the image data to the target receiving terminal according to the target transmission mode, and the target receiving terminal decodes the image data and sends the decoded image data to the display equipment for display.
The image display effect corresponding to each frame rate is as follows:
12 frame rate: when the frame rate of the picture is higher than about 10-12 frames per second, it is considered to be coherent, a phenomenon called persistence of vision, on which the principle of animation is based.
24 frame rate: the shooting and playing frame rate of the audio film is 24 frames per second, which is acceptable for the average person.
30 frame rate: early high dynamic video games, with frame rates less than 30 frames per second, were not consistent.
60 frame rate: in a practical experience, a 60 frame rate has a better experience than a 30 frame rate.
85 frame rate: the limit of brain processing video is that the human eye cannot resolve the difference between 85 frames and higher frame rates.
The above data can find that when the frame rate of the picture is lower than 12 frame rate, the performance is poor, the animation can not be consistent, the effect basically resembles a slide show, when the frame rate of the picture reaches 30 frame rate, the overall effect is slightly stuck, and when the frame rate of the picture reaches 60 frame rate, the animation can have smooth and smooth experience. Currently, the display is refreshed at a frequency of 30Hz, 60Hz, 120Hz, or 144Hz depending on its setting. The most common refresh frequency is 60Hz, which is mainly to inherit the previous setting of the refresh frequency of the television set to 60 Hz.
