The EJ523D is also an audio/video processor that supports HDMI signals and can perform a variety of signal processing tasks on-chip, such as compression, scaling, format conversion, and audio mixing. After processing, the final output can be USB. The product supports up to 4K2K 60fps and 1080P 120FPS Ultra HD video capture and streaming.
Introduction
EJ523D is a Capture Device of the USB3.2 Gen1 with Embedded DDR3 DRAM. The capture function supports 4K2K@60FPS Ultra High Definition (UHD) video through RGB/YCbCr interface and Audio through I2S interface. It can support H.264/H.265 compression to provide high video quality with limited bandwidth. EJ523D can record original contents from various sources such as smart device, camcorder, set-top box, DVD/BD player and game console. EJ523D uses OS native UVC and UAC drivers and is compatible with Microsoft Windows, Mac OS and Linux. It can fit in different media capture and streaming applications. It is the optimal solution for capturing Ultra high definition videos and post-production.
