Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a data transmission method, which includes steps S11 to S14.
Step S11, acquiring data to be transmitted between the receiving end chip and the receiving end chip.
In the embodiment of the invention, the chip which transmits the data to be transmitted to the receiving end chip becomes the output end chip. In an actual application scenario, the output end chip and the receiving end chip are relatively speaking, and specifically, the data flow direction between the chips is determined.
Step S12, determining the data type of the data to be transmitted.
In some embodiments, the data to be transmitted is divided into different data types according to different application scenarios. Data generated by a relative digital television or video monitoring device can be roughly divided into: video stream data, audio stream data, platform data, and user data. The video stream data and the audio stream data have high requirements on the real-time property of transmission, but can tolerate certain errors; the platform data and the user data have low requirements on the real-time property of transmission, but have strict requirements on the integrity of the data.
And step S13, acquiring target transmission data corresponding to the data to be transmitted according to the data type.
In the embodiment of the invention, some data to be transmitted can be directly used as target transmission data, and some data to be transmitted need to be correspondingly processed to obtain the target transmission data.
In some embodiments, the data type comprises a video stream data type, and special control words are inserted at the start and end positions of the data to be transmitted to obtain the target transmission data, and the special control words are used for introducing an error correction mechanism. In particular, special meanings may be indicated by the same special control word being repeated multiple times. Because a retransmission mechanism is not introduced, the design is simple, retransmission buffering is saved, the additional cost of bandwidth is reduced, and the real-time requirement is met.
In some embodiments, the data type includes an audio stream data type, and the data to be transmitted corresponding to the audio stream data type is provided with an error correction code, where the error correction code is used to automatically correct data in which an error occurs in data transmission at the receiving-end chip. Specifically, the audio stream data has small bandwidth requirement, the requirement of too much bandwidth cannot be increased due to the fact that the error correcting code is arranged, and a retransmission mechanism is not introduced, so that retransmission buffering is saved, and the real-time requirement is met.
In some embodiments, the data type includes a platform data type and/or a user data type, and an error detection code is inserted into the data to be transmitted to obtain target transmission data, where the error detection code is used to automatically check and find out error data at a receiving end chip. Specifically, the data type has strict requirements on data integrity, so that a retransmission mechanism and an error detection code are required to be introduced, wherein the error detection code may be CRC error detection or other codes. When the data type finds error data through an error detection code in the transmission process, retransmission needs to be carried out.
Step S14, selecting a transmission mechanism corresponding to the data type to transmit the target transmission data to the receiving end chip.
In the embodiment of the present invention, the transmission mechanism includes a unidirectional transmission and a bidirectional transmission, the unidirectional transmission mainly transmits real-time data (i.e., data with high requirement on real-time and certain error tolerance), and the bidirectional transmission mainly transmits integrity data (i.e., data with strict requirement on integrity and certain delay tolerance).
In some embodiments, the transmission mechanism includes unidirectional transmission, and when the data type includes a video stream data type and an audio stream data type, the video stream data type is preferentially transmitted to the receiving end chip in a unidirectional way, that is, the audio stream data needs to be transmitted in a transmission gap of the video stream data.
In some embodiments, the transmission mechanism comprises bidirectional transmission, and when the data type comprises a platform data type and/or a user data type, the target transmission data is divided into a plurality of data packets, wherein each data packet comprises an error detection code. Specifically, first information sent by a receiving end chip is received, and the first information is used for indicating that target transmission data is not correctly received; and/or receiving second information sent by the receiving end chip, wherein the second information is used for indicating that the target transmission data is correctly received. When receiving the first information sent by the receiving end chip, the corresponding data packet needs to be retransmitted to ensure the integrity of the data.

Data generated by a relative digital television or video monitoring device can be roughly divided into: video stream data, audio stream data, platform data, and user data. The video stream data and the audio stream data have high requirements on the real-time property of transmission, but can tolerate certain errors; the platform data and the user data have low requirements on the real-time property of transmission, but have strict requirements on the integrity of the data.
The second obtaining module 23 is configured to obtain target transmission data corresponding to the data to be transmitted according to the data type.

In particular, special meanings may be indicated by the same special control word being repeated multiple times. Because a retransmission mechanism is not introduced, the design is simple, retransmission buffering is saved, the additional cost of bandwidth is reduced, and the real-time requirement is met.
In some embodiments, the data type includes an audio stream data type, and the data to be transmitted corresponding to the audio stream data type is provided with an error correction code, where the error correction code is used to automatically correct data in which an error occurs in data transmission at the receiving-end chip. Specifically, the audio stream data has small bandwidth requirement, the requirement of too much bandwidth cannot be increased due to the fact that the error correcting code is arranged, and a retransmission mechanism is not introduced, so that retransmission buffering is saved, and the real-time requirement is met.

Specifically, the data type has strict requirements on data integrity, so that a retransmission mechanism and an error detection code are required to be introduced, wherein the error detection code may be CRC error detection or other codes. When the data type finds error data through an error detection code in the transmission process, retransmission needs to be carried out.
The transmission module 24 is configured to select a transmission mechanism corresponding to the data type to transmit the target transmission data to the receiving end chip.
In the embodiment of the present invention, the transmission mechanism includes a unidirectional transmission and a bidirectional transmission, the unidirectional transmission mainly transmits real-time data (i.e., data with high requirement on real-time and certain error tolerance), and the bidirectional transmission mainly transmits integrity data (i.e., data with strict requirement on integrity and certain delay tolerance).
In some embodiments, the transmission mechanism includes unidirectional transmission, and when the data type includes a video stream data type and an audio stream data type, the video stream data type is preferentially transmitted to the receiving end chip in a unidirectional way, that is, the audio stream data needs to be transmitted in a transmission gap of the video stream data.
