Before the system was implemented, it needs manual operations to inspect a number of set-top box output formats and relied on the naked eye to determine the accuracy of video output. This method is subjective and prone to errors. It is unable to verify many display modes. Furthermore, there is no detailed statistics to give manufacturers a good understanding of product quality or the verification results.
The DVP-7011UHE capture card was selected as the image capture device to be integrated into the system. DVP-7011UHE is capable to capture HDMI 2.0 video input and support 4K resolution (up to 4096x2160), which is on par with the video output formats of mainstream set-top boxes. Multiple DVP-7011UHE cards could be installed in a single system to capture video outputs from multiple set-top boxes and allow for large-scale automated inspection.
Many video output device manufacturers have attempted to implement automated inspection programs to replace manual visual inspection used in mass production. This is especially true when devices have different video output interfaces and require a specialized inspection procedure to inspect different video output formats. Devices such as laptops, Set-top boxes, video players, medical imaging equipment,and video converters can leverage automated image processing in video output inspection. As 4K video devices are becoming more ubiquitous, image capture cards play a key role in the approach to automation by capturing 4K images and comparing images in the inspection system. Image capture cards can boost production capacity and yield and reduce the risks involved in visual inspection.
