user manual of FEBON199 USB3.0 UVC SDI capture card (driver less /driver free/ no driver) for MAC / WIDNOWS


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
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)




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?

youtube或apple music當免費歌曲資料庫..家裡電視當KTV不在折騰了

  我的想法是希望手機投影到電視, 連接麥克風至聲卡,  能夠成為一個卡拉ok的系統 youtube上面的歌曲或apple music音樂庫,就可以當成ktv的歌庫來源! Youtube: 奇奇怪怪的mv都有, 很難找不到音樂資料庫 apple music: 可以app去除人聲,...
