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)

1920X1080P 60fps  ------>1920x1080p 60fps
                                           1920x1080P 50fps  ------>1920x1080p 50fps

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?






How to change audio sampling rate in MAC OSX?

step1: download AP "wirecast"

step2: follow the video clip








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.

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. up to 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
