Embodiment Construction

[0030] Those skilled in the art understand that, as stated in the background technology, in the prior art, when the digital component serial interface (SerialDigital Interface, referred to as SDI) chip is inspected at the factory, it is necessary to manually compare the items to be tested of each SDI chip one by one. , takes a long time and has low efficiency, which is not conducive to the mass production of SDI chips.

[0031] For example, according to the existing test plan, it is necessary to manually measure and monitor the level range of the SDI signal on a high-definition oscilloscope, and to check the amplitude and signal quality of the output signal through an eye diagram. The serial peripheral interface (Serial Peripheral Interface, referred to as SPI) reads the current frame rate of the 4-channel image in real time, and observes the image display and frame loss of multiple interfaces. The entire detection process is time-consuming and inefficient.

Abstract

The invention provides an automatic detection method and device of an SDI chip, a storage medium and a terminal. The method comprises the following steps: obtaining channel data of the SDI chip to bedetected, wherein the channel data are pre-stored in a chip library to be tested; comparing the channel data with a standard value, wherein the standard value is pre-stored in a preset standard database; and determining whether the SDI chip to be tested is qualified according to the comparison result. By adoption of the scheme provided by the invention, the screening efficiency of the SDI chips inthe production process can be improved, and the time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chip detection, in particular to an SDI chip automatic detection method and device, a storage medium, and a terminal. Background technique [0002] Serial Digital Interface (SDI for short) is a real-time uncompressed high-definition broadcast camera, which is another technological advancement in the field of security monitoring. Through the 75 ohm coaxial cable to transmit uncompressed digital video, the SDI chip can provide high-definition images for the monitoring center. [0003] In order to ensure that the SDI chip can output high-quality image data, it is particularly important to check the pass rate of the SDI chip. [0004] However, in the current factory inspection stage, the pass rate inspection of SDI chips is not only time-consuming but also inefficient, which is not conducive to the mass production of SDI chips. Contents of the invention [0005] The technical problem solved by the inventi...
