Mixing GV-SDI-204 with GV-Capture cards

GV-Capture cards

GV-SDI-204

GV-SDI-204 can be worked with

other types of GV-Capture Cards including

◆ GV-Combo A (1120A / 1240A / 1480A) without DSP Overlay

◆ GV-678B (GV-600B / GV-650B / GV-800B)

◆ GV-900A

The total number of channels cannot exceed 32 channels.

The sequence of the mix cards mode:

GV-5016 ← GV-SDI-204 → Other types of GV-Capture cards

In next version (V8560), GV-SDI-204 will also be able to be

worked with the following types of GV-Capture cards:

◆ GV-5016

◆ GV-4008

◆ GV-Combo B (1120B / 1240B / 1480B)

GV-SDI-204 Storage space

The following data was determined using default quality level Q3.

And the Single HDD with average R/W speed above 110 MBps.

Resolution Bit rate (bps) Frame rate (FPS)

1080P 7M 360

1080i 5.9M 360

720P 4.5M 720

The following is HDD calculating formula:

Ex: The bit rate of the scene 6 Mbps.

The file size of video clip (RTC Rec.) in 1 Minute = (6Mbps / 8) x 60 sec. = 45MB

The file size of video clips (RTC Rec.) in 1 Day = [ (45MB x 60 Min.) x 24HR ] / 1024 = 63.3 GB

The file size of video clips (RTC Rec.) in 1 week = 63.3GB x 7 = 443.1 GB

The following is the max. bit rate of GV-SDI-204 in each quality level:

Interlace & Progressive Intro The “i” of 1080i_60 stands for “Interlace”.

◆ GV-BX100’s job:

One field contains all the odd lines in the frame,

the other contains all the even lines of the frame .

◆ GV-SDI-204’s job:

It uses 2 fields to create 1 frame.

The “P” of 1080P_30 stands for “Progressive”.

GV-BX100 generated all the lines of each frame.
