What is a Video Digitizer?

It's a piece of hardware which is used for grabbing images from VCR/TV or VIDEO camcorder.

The HBI-V1 digitizer cartridge was produced by Sony. It was released in 1989 (one year after release of the MSX2+ computers) in Japan. Due to the TV standard incompatibility most of those cartridges available in Europe are converted to PAL from NTSC by Club Gouda or others.

What is included in the Video Digitizer package?

What are the specs of the HBI-V1 Video Digitizer?

Which screen modes does the HBI-V1 Video Digitizer support?

The digitizer can be used with an MSX2 computer, but then it will only be possible to digitize in screen mode 8 with 256 colours. On an MSX2+ the screen 10, 11 and 12 modes can be used too. The digitizing speed is not impressive, but enough if you do not expect to see real time video. The most used screen for digitizing is the last one (12) due to the big amount of colours.

Pictures can be digitized in:
Screen 8256×212/(424)256 RGB colours
Screen 10256×212/(424)12499 YJK colours
Screen 11256×212/(424)12499 YJK colours
Screen 12256×212/(424)19286 YJK colours

Several Screen 12 digitized images (256×212) 19286 colours

How can I digitize pictures in the 256×424 (interlaced) resolution?

Here comes an MSX-BASIC listing:

1 N$="IMAGE"
10 SCREEN 12,,,,,3
20 SETPAGE1,0
30 _AD(0,0,0,0,0,0,1)
40 SETPAGE 1,1
50 _AD(0,0,0,0,0,1,2)
55 A$=INKEY$
60 IFA$=""THEN20
70 IFA$=" "THENBEEP:A$=INPUT$(1):IFA$="S"ORA$="s"THENSETPAGE1,0:
BSAVE N$+".SC1",0,&HD3FF,S:SETPAGE1,1:BSAVE N$+".SC2",0,&HD3FF,S
80 GOTO20

You will need a good VCR with very good STILL/PAUSE function to use this program!

This program is written by TRUNKS.

How can I load the interlaced pictures in MSX-BASIC?

Try this:


10 SCREEN12,,,,,3
20 BLOAD"IMAGE.SC1",S
30 SETPAGE 1,1:BLOAD"IMAGE.SC2",S
40 GOTO40


How can I export my MSX pictures to (PC/MAC etc.)?

[bmpsv111.lzh] - Bitmap saver V1.11 by Kawasaki Yuusuke 1994. For MSX-DOS.

It's an excellent converter which is able to covert any MSX2 and MSX2+ BSAVED image into a [.BMP] file. Conversion in all cases is done without reducing the pallette. Here is a screen 12 picture (converted to .BMP) and then to .JPG:
