Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0069] Before introducing the embodiments of the present invention, the application scenarios of the embodiments of the present invention are firstly introduced. The data processing method provided by the embodiment of the present invention can be applied in application scenarios involving data transmission such as broadcasting, security, and video conferencing. 6G (SixthGeneration, sixth generation)-SDI such as SDI realizes data transmission. SDI is a standardized interface that can composite audio and video for data transmission through a coaxial cable. Since video and audio are transmitted in one direction and have no reliable transmission mechanism, transmission errors may occur during data transmission. For this reason, the embo...

Abstract

The invention discloses a data processing method and device and belongs to the technical field of multimedia. The method comprises the following steps: when a blanking row is determined to be detectedbased on the value of SAV and the value of EAV in a received data row, counting the continuous valid quantity; if the continuous valid quantity reaches the first preset quantity, analyzing valid datacontained in the detected valid row whenever the blanking row is determined to be detected based on the value of the SAV and the value of the EAV in the received data row after the EAV of a next blanking row is detected; in the analyzing process, when the blanking row is detected again based on the value of the SAV and the value of the EAV in the received data row, ending the analyzing operation,and recombining the valid data, obtained by analyzing according to a preset data row format on the basis of a preset resolution and a receiving timing sequence, into frames, thereby solving the problem of row lost or frame drop caused by discarding the data rows once a fault is detected by using the CRC, and improving the fault tolerance processing of the data.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a data processing method and device. Background technique [0002] At present, in the field of multimedia technology, most of them use SDI (Serial Digital Interface, digital component serial interface) for data transmission. According to the size of the transmission rate, the types of SDI include HD (High Definition, high resolution)-SDI, 3G (Third Generation, third generation)-SDI, etc. When data is transmitted through SDI, it is generally transmitted at the behavioral granularity. At the receiving end, the multiple data lines received by the SDI early-stage link are combined into a frame according to the receiving timing, and then the frame data is transmitted to the subsequent display processing module for display and other processing. [0003] Such as figure 1 As shown, a frame includes multiple data lines, among which the first few lines and the last few lines are cal...
