Compress Function:

1.Support PAL/NTSC4. 43/NTSC3. 58 video signals

2.The video compression is H.264, supports VBR as well as CBR, selectable video picture quality

3.Separatedly compress each audio and video signal stream, the compressed audio standard adopts G. 722

4.Compound H.264 is produced after compressing video and audio signals, the video and audio keep moving simultaneously and can set up no audio record when playback

5. 6 kinds of record image quality for choosing, users can select video quality according to the special need.
