Background
When the data signal is transmitted, the data signal needs to be correspondingly scrambled and correspondingly decoded, so as to enhance the data transmission effect and the transmission quality.
The decoding method is a process of restoring a digital code to its content or converting an electric pulse signal, an optical signal, a radio wave, or the like into information, data, or the like represented by it by a specific method. Decoding is the process by which the recipient recovers the received symbols or codes into information, each encoding algorithm having a particular decoding algorithm associated therewith. In the field of display technology, each bitstream mostly contains a fixed number of bits, and then in the decoding process, it is often necessary to perform an overall processing on one bitstream, resulting in a high hardware cost for supporting decoding.

In the embodiment of the present application, the bit number corresponding to the high color depth display product is 10bits as an example, and after the original data of the high color depth display product is encoded, the 10bits of data are converted into 12bits of data. Therefore, when the formed 12-bit data is decoded, a corresponding 12-bit decoding technique is required to decode the data.
In the embodiment of the present application, taking 12-bit decoded data as an example, 10-bit data is converted into 12-bit data, and the 12-bit data is decoded, so as to decode encoded data, thereby ensuring the integrity in the data transmission process, and effectively improving the decoding effect of the display panel.

As shown in fig. 1, fig. 1 is a schematic decoding flow diagram of a decoding method according to an embodiment of the present application. The decoding method in the embodiment of the application comprises the following steps:
s100: acquiring original data, coding the original data, and acquiring coded bit stream data;
s101: determining a data relation criterion, and judging the bit stream data according to the data relation criterion;
s102: if the bit stream data meets the data relation criterion, performing logic operation on the bit stream data of a first designated bit, and assigning values to the bit stream data which is not corresponding to the first designated bit to obtain first decoding data corresponding to the bit stream data;

s105: if the bit stream data corresponding to the second designated bit is the same, outputting the bit stream data and obtaining corresponding first decoding data;
s106: and processing the first decoding data to obtain second decoding data.
Specifically, the embodiment of the present application describes an encoding method for converting 10-bit data into 12-bit data as an example. When the encoded data is decoded, the encoded data is decoded by adopting a dual-judgment mode in the embodiment of the application, so that the aim of improving the decoding quality is fulfilled.
First, an original data is provided, and the original data can be encoded data encoded by an encoder. When encoding data, the encoding may be performed according to the data relation criterion provided in the embodiments of the present application. Thus, the bit stream data obtained after the encoding is finished has specific data characteristics and encoding information. Therefore, when decoding, it can be identified according to the data relation criterion in the embodiment of the present application.
After the encoded bit stream data information is obtained, the encoded bit stream data is judged and decoded step by step according to a determined data relation criterion, the data relation criterion provided in the embodiment of the application can be a corresponding relation of numerical values on different bit positions or a corresponding relation of numerical values on specific or appointed bit positions, and the definition of the data relation criterion can be set according to specific encoded data.
In the embodiment of the application, when the encoded data is decoded, the bit stream data is compared according to a specific data relation criterion. Thus, the bitstream data is compared to the data relation criterion. As shown in fig. 2, fig. 2 is a schematic diagram of a comparative process provided in the embodiment of the present application. If the obtained encoded bitstream data can meet the data relation criterion, logic operation is performed on the bitstream data on certain specific bits or designated bits in the bitstream data according to the relation in the data relation criterion.
The first decoded data obtained in the embodiment of the present application is incomplete decoded data, and the number of bits in the incomplete decoded data is generally greater than the number of bits after complete decoding, so that the incomplete decoded data needs to remove redundant bits, and finally, complete decoded data required in the embodiment of the present application is obtained.
As shown in fig. 3, fig. 3 is another schematic diagram of a data comparison process provided in the embodiment of the present application. If the obtained coded bit stream data can not meet the data relation criterion, carrying out secondary comparison on the coded bit stream data, and decoding the bit stream data through secondary comparison and judgment.
Specifically, when the comparison is performed for the second time, the comparison is performed on the bit stream data according to another data relation criterion. Specifically, the bit stream data of the second designated bit is compared and judged, if the bit stream data corresponding to the second designated bit are different in size, logic operation is performed on part of the bit, corresponding first decoded data is obtained, meanwhile, the rest of the bit is directly assigned, and finally the first decoded data is obtained.
The resulting incompletely decoded first decoded data is then processed to obtain completely decoded second decoded data.
And when the second time of comparison is carried out, if the corresponding bit stream data on the second designated bit are the same, directly outputting the bit stream data and obtaining corresponding first decoding data.
The first decoded data is processed again, that is, S107: and outputting the second decoded data.
Resulting in the final fully decoded second decoded data.
Therefore, in the embodiment of the present application, the encoded data is decoded by performing twice judgment on the originally obtained encoded data, so as to achieve the purpose of improving the decoding quality.
Further, as shown in fig. 4, fig. 4 is a schematic flowchart of another decoding algorithm provided in the embodiment of the present application. For further explanation of the decoding process. In the embodiment of the present application, a specific data relationship criterion and bitstream data information are taken as an example for explanation, and in the embodiment, data [ 11: 0 is original coded data, N [ i ] is 12bits, decoded data M [10:1] is decoded data, and M [ i ] is 10 bits. As shown in fig. 4.
First, a data relation criterion is set. The data relationship criterion provided in the embodiment of the present application is: it is defined that the zero bit N0 and the 1 st bit N1 have the same bit value and that the fifth bit N5 and the sixth bit N6 have the same value.
Specifically, OR (XOR (N [0], N [1], XOR (N [5], N [6 ]))) is 0, and it is determined whether OR not the zeroth bit N [0] and the 1 st bit N [1] are equal to each other, and at the same time, whether OR not the fifth bit N [5] and the sixth bit N [6] are equal to each other.
When the bitstream data to be decoded satisfies the above relationship criterion, performing a logic operation on a numerical value of a first specified bit, where in this embodiment of the present application, the defined first specified bit is: a fifth bit N [5], a sixth bit N [6], an eighth bit N [8], and a tenth bit N [10 ]. In particular, the method comprises the following steps of,
n5 is ═ N5; (the fifth bit N5 of the encoded data is inverted and assigned as the fifth bit N5 of the first decoded data).
N6 is ═ N6; (the sixth bit N6 of the encoded data is inverted and assigned as the sixth bit N6 of the first decoded data).
N < 8 > - (N < 8 >); (the eighth bit N8 of the encoded data is inverted and assigned as the eighth bit N8 of the first decoded data).
N10 is ═ N10; (the tenth bit N10 of the encoded data is inverted and assigned as the tenth bit N10 of the first decoded data).
And meanwhile, directly assigning values without processing the non-first designated bits. In the examples of the present application, the unspecified sites are: the zero bit N [0], the first bit N [1], the second bit N [2], the third bit N [3], the fourth bit N [4], the seventh bit N [7], the ninth bit N [9], and the eleventh bit N [11], and when assigning, the obtained bit value corresponding to the first decoded data may be the value of the bit of the original encoded data.
First decoded data of zeroth bit N [0] to eleventh bit N [11] obtained by the decoding processing.
When the bit stream data does not satisfy the data relation criterion, the secondary judgment is carried out on the coded data N [ i ], specifically, when the secondary judgment is carried out, the size comparison is carried out on the bit stream data of a plurality of specified bits.
In the embodiment of the present application, when the second determination is performed, the specified specific bit may be a second specified bit, where the second specified bit is at least two bits. Taking the zeroth bit N0 and the first bit N1 as two second designated bits as an example, according to the data relation criterion, it is determined whether the sizes of the zeroth bit N0 and the first bit N1 in the bit stream data are the same.
Specifically, N [0] XOR N [1] ═ 1; (determine whether the second designated bit, the zeroth bit N [0], is equal to the 1 st bit N [1 ]).
If the bit values of the zeroth bit N0 and the first bit N1 are different in size, logic operation is carried out on part of the bits, assignment is carried out on the rest of the bits, and when assignment is carried out, the corresponding bit values in the original bits can be directly substituted to finally obtain first decoding data information. In the embodiment of the application, the defined second designated bit is a zeroth bit N [0] and a first bit N [1 ]; some of the bits are a first bit N [1], a fourth bit N [4], a sixth bit N [6], a seventh bit N [7], and a ninth bit N [9], and the remaining bits are a zeroth bit N [0], a second bit N [2], a third bit N [3], a fifth bit N [5], an eighth bit N [8], a tenth bit N [10], and an eleventh bit N [11 ]. Thereby realizing decoding processing of the encoded data. Specifically;
n1 is-N1; (the first bit N1 of the encoded data is inverted and assigned to the first bit N1 of the first decoded data.)
N4 is-N4; (the fourth bit N4 of the encoded data is inverted and assigned as the fourth bit N4 of the first decoded data.)
N6 is ═ N6; (inverting the sixth bit N6 of the encoded data and assigning it to the sixth bit N6 of the first decoded data.)
N < 7 > - (N < 7 >); (the seventh bit N7 of the encoded data is inverted and assigned as the seventh bit N7 of the first decoded data.)
N < 9 > - (N < 9 >); (the ninth bit N9 of the encoded data is inverted and assigned as the ninth bit N9 of the first decoded data.)
And if the bit value of the zeroth bit N [0] is the same as that of the first bit N [1], directly outputting the data and obtaining first decoding data M [9:0 ].
The first decoded data obtained under different judgment conditions are incomplete decoded data, and redundant bit values are discarded because the number of bits in the first decoded data in the embodiment of the application is more than that of the finally decoded data. In the embodiment of the present application, the value of the zeroth bit [0] is discarded, and finally, the completely decoded second decoded data is obtained. Thereby enabling decoding of the entire encoded data.
