USB3.0 FEBON199 UVC SDI capture card just accept SDI video source 1920x1080p only
it can not accept 1920X1080i and 1280x720p
USB3.0 UVC SDI capture card engineer sample
Follow standard UVC (USB VIDEO CLASS). USB webcam like!
Driver free for MAC and windows
3G-SDI /HD-SDI to UVC !!!!
Almost NO latency!!
No video distortion from scale ic
it is less than 100m sec.
1920x1080p YUV422 60fps output
No compression!! NO video distortion!!
SDI INPUT -------->UVC OUTPUT (YUV)
Do NOT support 1920x1080i, 1280x720
Video and Audio Sync issue
UAC AUDIO Noise " Bi Bi Bi ..." issue
The UAC audio "Bi Bi Bi...." is due to the sampling rate.
The sample rate of audio from the HDMI machine are 44.1khz / 48khz.
The audio sample rate in the PC ( windows / MAC ) must equal the audio sample rate of HDMI
For eample:
if audio sample rate of hdmi is 44.1Khz and UAC audio 44.1Khz in the PC, the audio will be normal
if audio sample rate of hdmi is 48Khz and UAC audio 48Khz in the PC, the audio will be normal
If audio sample rate of hdmi is 44.1Khz and UAC audio 48Khz in the PC, the audio will happen "Bi Bi" noise.
If audio sample rate of hdmi is 48Khz and UAC audio 44.1Khz in the PC, the audio will happen "Bi Bi" noise.
How to Change audio sampling rate in WINDOWS?
How to change audio sampling rate in MAC OSX?
step1: download AP "wirecast"

step2: follow the video clip
UVC (video) and UAC (AUDIO ) is two independence stream.
The output from uvc grabber cad is sync.
After the PC cpu Process, it may have occur No Sync ISSUE.
This event is the same as the uvc webcam ( logitech webcam, Microsoft webcam)
All of UVC device ( camera , grabber card...) have this Sync issue.
It is due to the PC CPU process priority.
It need the software AP to build the SYNC function for Audio and video
Case 1: No SYNC function for audio and video
For example: windows amcap (record), MAC quicktime ( record)...
Case 2: Own SYNC function for audio and video
For example: Live google hangouts Youtube , skype.....
(The No sync event will be smaller)

MAC OSX DEMO
1. work on MAC OSX 10.10 quicktime
SDI INPUT is from "HDMI to SDI " box
SDI resolution is 1920x1080p 60fps
This demo will show you USB3.0 UVC SDI grabber card have video and audio output
2. Work on MAC OSX 10.10 quicktime.
SDI source is from HDCCTV SDI camera.
3. Work on WINDOWS 8.1 amcap.
SDI source is from HDCCTV SDI camera.

USB2.0 FEBON188 UVC SDI GRABBER CARD | USB3.0 FEBON199 UVC SDI GRABBER CARD | USB3.0 FEBON189 UVC SDI GRABBER CARD | |
UVC Output Of USB3.0 Port | Work! USB2.0 performance Up to 1280x720p 30fps @mjpg | The limitation is as below 1. USB3.0 XHCI 2. win8.1 / win10 /MAC 1920X1080P 60FPS @yuv | Work Up to 1920X1080P 30FPS @MJPG 1920X1080P 30FPS @MJPG |
UVC output of USB2.0 Port | Work! USB2.0 performance 1280x720p 30fps @mjpg | NO WORK | Work Up to 1920X1080P 15FPS @MJPG 1920X1080P 5FPS @YUV |
HDMI INPUT SOURCE | 1920X1080P 60/50/30/24 fps 1920x1080i 60/50 field 1280x720p 60/50 fps 720x480i 60 field 720x576i 50field | 1920X1080P 60/50/30/24 fps 1920x1080i 60/50 field 1280x720p 60/50 fps 720x480i 60 field 720x576i 50field | |
With auto scalar function | YES! | NO Scalar !! HDMI input resolution and frame rate must be equal the UVC resolution and frame rate | YES! |
Advantage | It is very easy to use | 1. No scalar ic “ video distortion “ 2. 1920x 1080p 60fps YUV output | It is very easy to use |
Disadvantage | Video scalar ic distortion | It have many use limitation | Video scalar ic distortion |
