Background
In the high-speed transmission process of vehicle-mounted video data, in order to ensure the accuracy of data transmission and improve the external interference resistance of the vehicle-mounted video data, the transmitted data needs to be randomized (Randomize). Usually, a sending end of a device or a system adds codes to data to be transmitted to realize data randomization, and meanwhile, needs to avoid occurrence of 0 length (multiple continuous 0 s) and 1 length (multiple continuous 1 s), and needs to perform direct current balance (DC balance) within a certain period; the receiving end receives the processed data and carries out inverse processing on the additional code, namely, after decoding, the actually transmitted data is obtained.
In the prior art, in the process of randomizing and adding codes, in order to avoid the situation that a certain number of digits are added due to the occurrence of the length 0 and the length 1, the code adding information is transmitted to a receiving end, so that the receiving end can correctly decode. Due to the limitation of bandwidth, the less the added number is, the less the influence on the data transmission efficiency is. In the existing coding process, the bits with length 0 and length 1 are longer, generally reaching 66 bits, so that the problems of bandwidth occupation caused by synchronous sending and receiving, data transmission speed limitation and transmission efficiency reduction can occur.

In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.
In the high-speed data transmission technology, the following encoding means are common for satisfying both randomness and dc balance:
1.8b10b encoding:
the advantages are that: the direct current is balanced by 28 bits, and the longest 0 or the longest 1 is less than 10 bits;
the disadvantages are as follows: an increased number of bits of 25% is required, randomness is relatively poor, and synchronization is required for the receiving end and the transmitting end.
2.64b66b encoding:
the advantages are that: the randomness is strong, the number of bits required to be added is less (only 2/N bits are needed), and the sending end and the receiving end can be self-synchronized;
the disadvantages are as follows: the long 0 and long 1 digit is too long, which can reach 66 digits usually, and the time required for DC balance is longer.
Nb (N +2) b DC balanced + randomized, as encoded with 8b10b, 64b/66b, 128b/130b, etc.:
the advantages are that: the time required by direct current balance is short, and the length of the random selectable digit can be controlled, so that the digits with the length of 0 and 1 are controlled;
the disadvantages are as follows: the percentage of the additional digits is not fixed, and the sending end and the receiving end need to be periodically synchronized, so that the bandwidth is occupied.
The 8bit raw data can be divided into two parts: the 8-bit data can be recorded as d.x.y if the lower 5-bit EDCBA (assuming its decimal value X) and the upper 3-bit HGF (assuming its decimal value Y). In addition, 12 control characters are also used in 8B/10B coding, and can be used as state identifiers of frame start, frame end, transmission idle and the like in transmission. Similar to the notation of data characters, control characters are commonly denoted as k.x.y. There are 256 types of 8-bit data, plus 12 control characters, for a total of 268. 1024 types of 10-bit data can be selected from the 10-bit data, a part of the 10-bit data can represent 8-bit data, and the number of 0 s and the number of 1 s in the selected code pattern are equal to each other as much as possible. In 8B/10B coding, K28.1, K28.5 and K28.7 are used as control characters of a K code and are called as 'comma'. In any data combination, the comma only appears as a control character and does not appear in the data payload section, so the comma characters may be used to indicate the start and end flags of the frame, or to always correct the control character for alignment with the data stream.
As shown in fig. 1, the coding method for data transmission proposed in this embodiment uses a coding algorithm, which includes first coding bits and second coding bits; the encoding steps include:
step S101: obtaining direct current balance data based on transmission data to be coded, and putting the direct current balance data into first code adding bits;
step S102: obtaining a synchronous sequence based on the random sequence, and placing the synchronous sequence into a second code adding bit;
step S103: putting transmission data to be coded into data bits in a data transmission protocol;
step S104: the first and second coded bits are appended to the data bits.
The preferred coding algorithm of this embodiment is to add 2 digits, one digit is used for dc balance, and one digit, i.e. Data Sync (DS), is used for random sequence synchronization of the transmitting end and the receiving end, and transmit information that can be utilized by other receiving ends from the transmitting end.
The random sequence employs PRBSm (random sequence of m bits). 2mEach clock period is a random sequence period, and the DS sequence is self-balanced by direct current. With 8b10b encoding, the clock period is an integer multiple of 10. According to 2mBy a nearest multiple of 10, e.g. 27If 128, take 130; 29Is 512, get 510, etc.
The DS sequence uses the K-code (control character) in the 8b10b code as synchronization for the sender and receiver. The first K x 0 clocks of the DS sequence can generate K K-codes, and K is preferably a number more than 3; the remaining clock cycles may be used to send other information. Since the K-code of the DS sequence is one-to-one corresponding to the start of the random sequence. The receiving end can de-randomize the received data in reverse direction by using the DS K-code synchronous random sequence, and the specific flow is shown in fig. 2 to 4.
The preferred coding algorithm of this embodiment adds 2 digits, wherein 1 digit is allocated to dc balance, and the other 1 digit is used for synchronization of the transmitting end and the receiving end, and can transmit other more information. The method has the advantages that the time required by direct current balance is very short; meanwhile, M bits are randomly selected, the longest is 0, the longest is 1, and the M bits are used as the longest, so that the synchronization does not occupy the bandwidth, and the continuous synchronization can be realized.
In summary, the present embodiment has the following beneficial effects, including:
1. synchronizing a sending end and a receiving end by using a DS sequence;
the DS sequence can also transmit other information at the same time;
d, self direct current balance of the DS sequence;
4. low overhead, only 1 bit encoding is added.
As shown in fig. 5, the present embodiment further provides an encoding apparatus for data transmission, including:
the direct current balance module is used for obtaining direct current balance data based on transmission data to be coded;
a synchronization module for obtaining a synchronization sequence based on the random sequence;
and the coding module is used for placing the direct current balance data into a first code adding bit, placing the synchronous sequence into a second code adding bit, placing the transmission data to be coded into a data bit, and attaching the first code adding bit and the second code adding bit to the data bit.
