Detailed Description
The present application is described in further detail below with reference to figures 1 to 8.
The embodiment of the application discloses an HDMI data transmission method.
Referring to fig. 1, the hdmi data transmission includes:
s1, acquiring a transmission data value of data when data transmission is carried out;
s2, judging whether the transmission data value exceeds a preset data value or not;
s3, when the transmission data value exceeds a preset data value, acquiring a bandwidth increasing instruction;
and S4, increasing the transmission bandwidth for transmitting the data exceeding the preset data value based on the bandwidth increasing instruction.
HDMI data is currently common transmission data, but in the current process of transmitting data through multiple interfaces, each interface generally transmits at a relatively fixed transmission rate, and in the process of transmitting multiple data, the bandwidth of data transmission is generally relatively fixed, so that a relatively large transmission bandwidth is also occupied in the process of transmitting relatively small data, which results in a relatively slow process of transmitting large data, and therefore the flexibility of adjusting the bandwidth in the process of transmitting data is relatively low. Therefore, in order to flexibly adjust the bandwidth, the following operations can be performed:
specifically, when data is transmitted to different devices, a transmission data value of the data, that is, the size of the data, is obtained first, and the size value of the data, that is, the transmission data value, can be obtained by reading an attribute value of the data. And then, judging whether the transmission data value exceeds a preset data value, and determining whether the transmission bandwidth of the data needs to be adjusted by judging whether the transmission data value exceeds the preset data value, wherein the preset data value can be set according to an actual situation, for example, can be 10GB, and certainly can be other values.
If the transmission data value does not exceed the preset data value, the transmission bandwidth of the data may not be adjusted, and in other embodiments, the transmission bandwidth may be appropriately adjusted. If the transmission data value exceeds the preset data value, the data to be transmitted is proved to be larger, so that the bandwidth for transmitting the data to the equipment needs to be properly adjusted, and the data transmission speed is conveniently improved.
Therefore, when the transmission data value exceeds the preset data value, the bandwidth increasing instruction is obtained, and the transmission bandwidth for transmitting the data exceeding the preset data value is increased according to the bandwidth increasing instruction. The specific adjustment mode may be that the system reserves a certain allocable transmission bandwidth, and then after the bandwidth increase instruction is obtained, allocates the reserved bandwidth to the corresponding data to be transmitted, so as to increase the bandwidth for data transmission, which may be other modes.
By means of the method, the transmission bandwidth of the data exceeding the preset data value can be flexibly adjusted, so that the transmission speed of the data can be flexibly adjusted, and the flexibility in the data transmission process can be improved.
Referring to fig. 2, in order to better allocate the reserved allocable transmission bandwidth, in another embodiment, the obtaining a bandwidth increase instruction includes:
s11, acquiring a data difference value based on the transmission data value and a preset data value;
s12, acquiring a bandwidth adjustment table, wherein the bandwidth adjustment table comprises a bandwidth adjustment value and a difference value interval corresponding to the bandwidth adjustment value;
s13, matching the data difference value with the difference value interval and obtaining a corresponding bandwidth adjustment value as an actual adjustment value;
and S14, generating a bandwidth increasing instruction based on the actual adjusting value.
Specifically, a data difference value is first obtained according to the transmission data value and the preset data value, that is, a value obtained by subtracting the preset data value from the transmission data value is a data difference value. And then acquiring a bandwidth adjustment table, wherein the bandwidth adjustment table is a preset data table and comprises a bandwidth adjustment value and a difference value interval corresponding to the bandwidth adjustment value. The bandwidth adjustment value is a bandwidth value for allocating the allocable transmission bandwidth to the normally transmitted data. The difference interval is a range value, and when the data difference value is located in the corresponding difference interval, the corresponding bandwidth adjustment interval can be obtained.
Therefore, after the data difference value and the bandwidth adjustment table are obtained, the data difference value is matched with the difference value interval in the bandwidth adjustment table, so that a corresponding bandwidth adjustment value is obtained and is used as an actual adjustment value. And finally, generating a bandwidth increasing instruction according to the actual adjustment value, so that the transmission bandwidth of the data is increased according to the size of the actual adjustment value through the bandwidth increasing instruction, and the allocable bandwidth can be better and more reasonably allocated.
Of course, in an implementation manner of this embodiment, if it is necessary to adjust the transmission bandwidth of the data whose transmission data value does not exceed the preset data value, that is, when the data difference value is a negative value, the data difference value may also be matched with the difference interval, where the matched bandwidth adjustment value is a negative value, and then a bandwidth compression instruction is generated according to the bandwidth adjustment value at this time, and the obtained negative value is added to the transmission bandwidth of the current data, so that the bandwidth compression may be implemented.
That is to say, when the obtained bandwidth adjustment value is a positive value, the obtained instruction is a bandwidth increasing instruction, and when the obtained bandwidth adjustment value is a negative value, the obtained instruction is a bandwidth decreasing instruction, so that the transmission bandwidth of smaller data is conveniently compressed, the allocable bandwidth is conveniently increased on the basis of reserving the allocable bandwidth, the transmission bandwidth of more data with the transmission data value exceeding the preset data value is conveniently increased, and the transmission speed of the data is improved. And further, the transmission bandwidth of the data can be better adjusted.
Referring to fig. 3, in order to reduce the information processing pressure on bandwidth adjustment during data transmission, in another embodiment, before acquiring a transmission data value of data, the method further includes:
s21, acquiring the transmission quantity of data;
s22, when the transmission quantity is one, the step of acquiring the transmission data value of the data is not executed;
s23, when the transmission quantity is at least two, executing the step S1.
Specifically, before step S1, that is, acquiring a transmission data value of data, acquiring a transmission number of the data, that is, the number of interfaces through which the system can read to perform data transmission, where the number of interfaces is the transmission number of the data.
When the transmission number is one, that is, there is only one data transmission task, step S1 may not be executed, that is, all the bandwidths may be directly allocated to the current data transmission task, so that a subsequent series of determination steps are not required, and thus the processing pressure of the data may be reduced.
When the number of the data is at least two, the transmission bandwidth of the data needs to be adjusted and allocated, so that the step S1 is executed to obtain the transmission data value of the data, thereby facilitating the adjustment of the transmission bandwidth of the data in the subsequent steps.
Referring to fig. 4, in order to better adjust the transmission bandwidth of the data, in another embodiment, when the number of transmissions is at least two, before acquiring the bandwidth increase instruction, the method further includes:
s31, determining the data quantity of data with the transmission data value exceeding a preset data value;
s32, when the number of the data is one, acquiring a bandwidth compression instruction to compress the transmission bandwidth of the data of which the transmission data value does not exceed the preset data value, and acquiring a first compression bandwidth;
s33, acquiring a bandwidth increasing instruction based on the first compressed bandwidth to increase the transmission bandwidth of the data with the transmission data value exceeding the preset data value;
s34, when the number of the data is at least two, sorting the data with the transmission data value exceeding the preset data value according to the preset sorting priority to obtain first sorted data;
s35, sorting the data of which the transmission data value does not exceed the preset data value according to a preset compression priority to obtain second sorted data;
s36, acquiring a bandwidth compression instruction, sequentially compressing second sequencing data according to a preset compression rule, and acquiring a second compression bandwidth;
and S37, acquiring a bandwidth increasing instruction based on the second compressed bandwidth, and sequentially increasing the transmission bandwidth of the first sequencing data according to a preset increasing rule.
Specifically, when the number of transmissions is at least two and before the bandwidth increase instruction is obtained, the data number of the data whose transmission data value exceeds the preset data value is determined, and in the data transmission process, the allocation of the bandwidth may be adjusted in a manner that an allocable bandwidth is not reserved, but in a manner that the transmission bandwidth of the data whose transmission data value does not exceed the preset data value is compressed and the transmission bandwidth of the data whose transmission data value exceeds the preset data value is allocated.
Therefore, when the number of data is one, the bandwidth compression instruction is obtained to compress the transmission bandwidth of the data whose transmission data value does not exceed the preset data value, and the first compression bandwidth is obtained, and the manner of obtaining the bandwidth compression instruction may also be the manner of matching the bandwidth adjustment table to obtain the transmission bandwidth of the data whose compressed transmission data value does not exceed the preset data value, that is, the first compression bandwidth.
Then, a bandwidth increase instruction is obtained according to the first compression bandwidth to increase the transmission bandwidth of the data with the transmission data value exceeding the preset data value, namely, the transmission bandwidth of the data with the transmission data value exceeding the preset data value is increased according to the size of the first compression bandwidth.
When the number of the data is at least two, sorting the data with the transmission data value exceeding the preset data value according to a preset sorting priority to obtain first sorting data, wherein the data with the transmission data value exceeding the preset data value is called excess data, the preset sorting priority is a priority from large to small, namely the excess data is sorted in a sequence from large to small, and the obtained sorting data is the first sorting data.
And sorting the data of which the transmission data value does not exceed the preset data value according to a preset compression priority to obtain second sorted data, wherein the data of which the transmission data value does not exceed the preset data value is called non-excess data, the preset compression priority is also the priority from large to small, namely the non-excess data is sorted according to the sequence from large to small, and the obtained sorted data is the second sorted data.
And then, acquiring a bandwidth compression instruction, sequentially compressing the second sequencing data according to a preset compression rule, and acquiring a second compression bandwidth. The preset compression rule may compress all the second sorted data by the same bandwidth, or compress the second sorted data according to a preset proportion, where the preset proportion may be the size of each data in the second sorted data, and then compress each data according to the preset compression proportion. And then integrating all compressed bandwidths obtained by compression, wherein the sum of the obtained final compressed bandwidths is the second compressed bandwidth.
And finally, acquiring a bandwidth increasing instruction based on the second compressed bandwidth, and sequentially increasing the transmission bandwidth of the first sequencing data according to a preset increasing rule, namely acquiring a bandwidth increasing instruction according to the size of the second compressed bandwidth and distributing the second compressed bandwidth according to the bandwidth increasing instruction. The second compressed bandwidth is allocated according to a preset increasing rule, and then the allocated bandwidth is sequentially increased to the transmission bandwidth of the first sequencing data, so that the transmission bandwidth is increased. The preset increasing rule can be set according to actual conditions.
Referring to fig. 5, in order to increase the manner of increasing the transmission bandwidth of the first sorted data, in another embodiment, sequentially increasing the transmission bandwidth of the first sorted data according to a preset increase rule includes:
s41, obtaining average distribution bandwidth based on the data quantity and the second compression bandwidth;
s42, sequentially increasing the transmission bandwidth of the first sequencing data according to an average rule based on the average distribution bandwidth;
or the like, or, alternatively,
s43, acquiring data with a transmission data value exceeding a preset data value as excess data;
s44, acquiring a difference value between a transmission data value of the excess data and a preset data value as an excess difference value;
s45, acquiring the total value of all the excess difference values as an excess total value;
s46, acquiring an excess ratio of the excess difference value in the excess total value;
s47, obtaining a proportional allocation bandwidth based on the excess ratio and the second compressed bandwidth;
and S48, sequentially increasing the transmission bandwidth of the first sequencing data according to a proportion rule based on the proportion distribution bandwidth.
Specifically, the sequentially increasing the transmission bandwidth of the first-ranked data according to a preset increasing rule may be increasing according to an average rule, or increasing according to a proportional rule. Wherein, the increasing according to the average rule specifically comprises the following steps:
firstly, the average allocated bandwidth is obtained according to the data quantity and the second compressed bandwidth, that is, the second compressed bandwidth is averaged according to the data quantity, that is, a value obtained by dividing the second compressed bandwidth by the data quantity is the average allocated bandwidth, and when the second compressed bandwidth cannot be evenly divided, the value of the second compressed bandwidth can be reduced until the second compressed bandwidth can be evenly divided and is unknown. For example, the amount of data is 3, the second compressed bandwidth is 100MB/s, and the second compressed bandwidth cannot be divided equally, so the second compressed bandwidth is reduced to 99MB/s, and can be divided equally, i.e. divided equally by 33MB/s.
And then, sequentially increasing the transmission bandwidth of the first sorted data according to the average distribution bandwidth and the average rule, namely, sequentially increasing the equally-distributed bandwidth to the corresponding data transmission bandwidth according to the sorting sequence of the first excluded data, and further increasing the transmission bandwidth.
And the increasing according to the proportion rule specifically comprises the following steps:
firstly, data with a transmission data value exceeding a preset data value is obtained as excess data, then the difference value between the transmission data value of the excess data and the preset data value is obtained as an excess difference value, namely the difference value between the transmission data value of each excess data and the preset data value is obtained, namely, several excess difference values exist in several excess data. It is to be understood that the excess difference is positive.
And then acquiring the total value of all excess difference values as the excess total value, namely acquiring the sum of all excess difference values. Then, the excess ratio of the excess difference values in the excess total value, namely the proportion of each excess difference value in the excess total value, is obtained. That is, each excess difference value is divided by the total excess value, and the obtained value is the excess ratio.
And then obtaining the proportional allocation bandwidth according to the excess ratio and the second compression bandwidth, namely multiplying the value of the compression bandwidth obtained by multiplying the excess ratio of the corresponding excess data by the second compression bandwidth, namely obtaining the proportional allocation bandwidth. That is, each excess data corresponds to a corresponding allocated proportion of bandwidth.
And finally, sequentially increasing the transmission bandwidth of the first sequencing data according to the proportion rule according to the proportion distribution bandwidth. That is, the process of obtaining the proportional allocation bandwidth is sequentially obtained according to the sorting order of the first sorting data, so that the order of the proportional allocation bandwidth corresponds to the data corresponding to the first sorting data one by one, and at this time, the obtained proportional allocation bandwidth is sequentially added to the transmission bandwidth corresponding to the first sorting data according to the order, so as to increase the transmission bandwidth.
Accordingly, the bandwidth of data transmission can be increased in different ways, the diversity of bandwidth increase can be increased, and the selectivity of the way of bandwidth increase can be improved.
Referring to fig. 6, when the transmission bandwidth adjustment needs to be performed on data whose transmission data value does not exceed the preset data value, that is, non-excessive data, in another embodiment, when the transmission data value does not exceed the preset data value, the method further includes:
s51, acquiring the quantity of data for data transmission as the current quantity;
s52, when the current number is one, acquiring the maximum transmission bandwidth;
s53, transmitting data based on the maximum transmission bandwidth;
s54, when the current number is at least two, obtaining an average bandwidth based on the current number;
and S55, transmitting all data based on the average bandwidth.
Specifically, the number of data to be transmitted at this time is acquired as the current number, and all the data to be transmitted at this time are non-excessive data. Then, the value of the current quantity is determined, and when the current quantity is one, the maximum transmission bandwidth, that is, the maximum transmission bandwidth allowed by the system at the moment, is obtained. And then the data is transmitted according to the maximum transmission bandwidth, so that the data can be transmitted at the fastest speed at present.
When the current number is at least two, the average bandwidth is obtained according to the current number, that is, the current allowed maximum bandwidth is divided by the current number, the obtained bandwidth is the average bandwidth, and then all data are transmitted according to the average bandwidth, that is, all non-excess data are transmitted by the same transmission bandwidth, so that the adjustment mode is simple and convenient.
Referring to fig. 7, in order to increase the diversity of the non-oversubscribed data bandwidth adjustment options, in another embodiment, when the current number is at least two, the method further includes:
s61, acquiring data value proportions of all transmission data values;
s62, acquiring a proportional bandwidth based on the data value proportion;
and S63, transmitting corresponding data based on the proportional bandwidth.
Specifically, when the current number is at least two, the data value ratios of all the transmission data values are obtained, that is, the sum of all the transmission data values is obtained first, and then each transmission data value is divided by the sum, so that the obtained value is the data value ratio of each data.
Then, the proportional bandwidth is obtained according to the data value ratio, and the obtaining mode may be to obtain the maximum transmission bandwidth allowed by the system at this time, and then multiply the data value ratio by the maximum transmission bandwidth, and the obtained bandwidth value is the proportional bandwidth of each data. And finally, transmitting corresponding data according to the proportional bandwidths, namely, each proportional bandwidth corresponds to one corresponding data, and then transmitting the data according to the proportional bandwidth allocated to the data. And the diversity of the selection for adjusting the transmission bandwidth of the non-excessive data can be improved.
The implementation principle of the HDMI data transmission method in the embodiment of the present application is as follows: when data transmission is carried out, a transmission data value of the data is obtained, whether the transmission data value exceeds a preset data value or not is judged, and when the transmission data value exceeds the preset data value, a bandwidth increasing instruction is obtained, so that the transmission bandwidth for transmitting the data exceeding the preset data value is increased according to the bandwidth increasing instruction.
