eEver EJ523D chip enables 4Kp60 video capture or streaming over USB 3.2

eEver Technology, a subsidiary of eTron Technology, has launched the EJ523D 4Kp60 audio and video capture and streaming processor with a USB 3.2 interface, along with a reference platform currently showcased at COMPUTEX 2023.

Over the last few years, we’ve covered some low-cost HDMI to USB 2.0 dongles that capture video up to 1080p30, followed by HDMI to USB 3.0 dongles handling up to 4Kp30, but the latest eEver EJ523D chip will be found in USB 3.2 adapters to capture at up to 4Kp60 resolution with H.265 encoding or 4Kp30 in the NV12 format.

Some highlights of the EJ523D:

  • Video capture resolution and frame rate
    • 4K@ 30 fps or 2K @ 120 fps with NV12
    • 4K @ 60 fps with H.265 10-bit HDR/H.264 encoding
    • MJPEG encoding is also supported up to 4K @ 60 fps
  • Integrated scaler – Full range up & down
  • De-interlacing – De-interlace i to p mode up to 4K resolution
  • Audio – I2S interface, audio mixer with resampling support
  • Support for PiP (Picture-in-Picture), OSD (On-screen display), and mirror modes
  • Host interface – USB 3.2 Gen 1

The company expects the EJ523D Stream Processor Unit  (SPU) – also known as SPU–EJ523D – to be used in various applications such as live streaming of video games, live commerce to interact with customers, telemedicine, industrial remote assistance and training, distance learning, as well as teleconferencing and remote office work. One example of the latter could be combining presentations with live images and audio from participants.

The EJ523D EVB is currently demonstrated at COMPUTEX 23 and the photo below appears to show the evaluation board connected to a Windows 11 machine doing 4K video streaming with virtually no CPU usage since most of the work is offloaded to the GPU and video processing engine (VPE).

USB 3.2 gen1 = usb 3.1 gen1 = usb 3.0
All this are 5gbps per lane not 10.
so for 10gbps need 2 lanes gen1, aka 3.2 gen1x2, and i dont known any chipset or MB implementing this.
