Problems solved by technology

However, the transmission network of the Internet is not always reliable. During the transmission process, due to various instabilities, data packet loss will occur.
The solution to the problem of data packet loss in the prior art is that when the receiving end confirms that there is a packet loss, it requests the sending end to retransmit the data, and the sending end retransmits the entire data packet to the receiving end according to the request, resulting in large memory consumption and low transmission efficiency

Embodiment 1

[0063] figure 1 The flow chart provided by the embodiment of the present application is given. The data processing method based on the decoding exception provided in the embodiment of the present application can be executed by the data processing device based on the decoding exception, and the data processing device based on the decoding exception can use hardware and and / or implemented in software and integrated in computer equipment.

[0064] The following description will be described by taking the data processing device based on the decoding exception as an example to execute the data processing method based on the decoding exception. refer to figure 1 , the data processing method based on decoding exception includes:

[0065] S101: Receive encoded data and a series of random codes from the sending end, and decode the data to obtain a type code in the data.

[0066] S102: Obtain the recovery capability index of the pair of currently received data according to the type c...

Embodiment 2

[0082] Such as figure 2 As shown, the embodiment of the present invention also provides a data processing method based on decoding exception, including:

[0083] S201: Receive encoded data and a series of random codes from the sending end, and decode the data to obtain a type code in the data.

[0084] S202: Obtain the recovery capability index of the pair of currently received data according to the type code, and when the recovery capability index is greater than the first threshold, obtain a recovery mode of historical data corresponding to the type code when decoding is abnormal, and The data is recovered according to the recovery mode; when the recovery index is smaller than the first threshold, a retransmission request is sent to the sending end.

[0085]In this embodiment, obtaining the restoration method of historical data of the type corresponding to the type code when the decoding is abnormal, and restoring the data according to the restoration method includes: obta...

Embodiment 3

[0090] Such as image 3 As shown, the embodiment of the present application provides a data processing device based on decoding exception, including a data receiving and decoding module 301 and a data recovery judging module 302 . Wherein, the data receiving and decoding module 301 is used to receive encoded data and a series of random codes from the sending end, and decode the data to obtain the type code in the data. The data recovery judging module 302 is used to obtain the recovery ability index of the pair of currently received data according to the type code, and when the recovery ability index is greater than the first threshold, obtain historical data of the type corresponding to the type code when decoding is abnormal recovery mode, and recover the data according to the recovery mode; when the recovery index is less than the first threshold, send a retransmission request to the sending end.

[0091] Further, the data includes a number of continuous data frames and ty...

Abstract

The embodiment of the invention discloses a data processing method and device based on decoding exception, and the method comprises the steps: receiving a data code, and decoding data to obtain a typecode; acquiring a recovery capability index of the data according to the type code, acquiring a recovery mode of historical data of a type corresponding to the type code when decoding is abnormal when the recovery capability index is greater than a first threshold, and recovering the data according to the recovery mode; when the recovery index is smaller than the first threshold, sending a retransmission request to the sending end. According to the technical scheme provided by the embodiment of the invention, the type code corresponding to the data feature is carried on the data sent each time, when the receiving end receives the data, the receiving end can timely recover the capability index of the data according to the type code, and when the recovery capability index meets the condition, the historical recovery condition of the parameter is replied; when the recovery capability index cannot reach the condition, the retransmission request is sent, so that the channel transmission utilization rate can be improved, the data transmission efficiency is improved, and the data transmission delay is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data communication, and in particular, to a data processing method and device based on decoding exceptions. Background technique [0002] With the development of the Internet, various network applications need to establish data transmission. However, the transmission network of the Internet is not always reliable. During the transmission process, data packets may be lost due to various instabilities. The solution to the problem of data packet loss in the prior art is that when the receiving end confirms that there is a packet loss, it requests the sending end to retransmit the data, and the sending end retransmits the entire data packet to the receiving end according to the request, resulting in large memory consumption and low transmission efficiency . Contents of the invention [0003] The embodiment of the present application provides a data processing method and device ...
