1. Another way of transporting video signals The three colour components red green and blue are transported separately This video signal gives high quality images It s often inputted or outputted via a SCART or DIN connector Connector that outputs and or inputs both CVBS and RGB video signals The RGB signal though is not always supported by this connector Only CVBS video can be inputted an outputted by the same connector The RGB video is either inputted or outputted Audio signals are also inputted and or outputted by this connector The action that one image is displayed upon another The hindmost screen is visible when the foremost image is transparent The Video9000 superimposes the GFX9000 graphical image upon an external video source coming from a VCR TV or camera or the MSX computer Almost the same as CVBS video except that the chrominance colour part and the luminance black and white part synchronization are transported separately It gives a higher quality than CVBS video but less than RGB video S VHS is also called S Video or Y C video VIDEO VIDEO OUTPUT WIPE Appendix B Terms explained Abbreviation for Video Cassette Recorder Another definition of CVBS video See CVBS for more information The connector that outputs the CVBS video signal Most video equipment have such a CVBS output It can be outputted by a SCART or DIN connector or by a special CVBS connector CINCH connector2. CVBS video in connector RGB video in connector Colour saturation Intensity Contrast 3 Connections and controls Use this connector when having a S VHS camera or VCR This gives a higher quality than CVBS video but less than RGB Use this connector when having an external video source with only a video output CVBS cinch connector Use a cinch cinch or SCART cinch cable Most normal cameras and VCRs do have a CVBS output outputted via cinch or SCART Connect the SCART or DIN RGB output of your MSX computer to the Video9000 via this cable It may also be used as external video input when having a VCR with RGB output When having connected an external video source to the S VHS 3 or CVBS 4 video input the colour saturation level can be changed here clockwise is more colour completely counter clockwise will give a black and white image When having connected an external video source to the S VHS 3 or CVBS 4 video input the intensity contrast level can be changed here clockwise is increasing intensity NOTE The fact that a VCR has a SCART connector does not mean that the RGB signals are used by that VCR Standard VCRs only use the CVBS signal of the SCART plug instead of the RGB signals Because the Video9000 only has an RGB output the images can t be recorded directly by these VCRs but an RGB to CVBS and or S VHS converter must be used These converters can be bought in electronic stores or in the fut
3. The effect that one image is gradually replaced by another image For example the second image will be slowly visible by making the first image transparent more and more 3l Guarantee Sunrise Swiss guarantees the errorfree operation of the Video9000 during 12 months after purchasing In case of failure Sunrise Swiss decides on repairing or changing the Video9000 Any changes to the Video9000 are not covered by this warranty This warranty will be lost if the Video9000 bottompanel has been removed In this manual Video9000 does mean all the components that are added to the GFX9000 32
4. equally speeded with a VCR or camera the 9000 must be set at 50Hz Circuit that synchronizes the GFX9000 with an external video source in order to be able to superimpose or digitize Synchronize means that both signals are running equally fast and that both signals are starting with the same screen line at the same time 29 Appendix B Terms explained INTENSITY LUMINANCE MIX OUT OVERSCAN MODE PAL POWER BASIC RGB VIDEO SCART SUPERIMPOSE S VHS 30 Also called contrast See contrast for more information The part of a video signal that represents the black and white information of the screen Compare chrominance The action that two images are added and displayed together Before adding the brightness of both images is reduced to 5096 A basic command that can be used to control the GFX9000 and Video9000 directly The screen mode of the GFX9000 in which no border is visible around a graphical image The video standard used by most European video devices It is the way at which the CVBS video signal is made The Video9000 is supporting PAL video In the United States and Japan the NTSC standard is used This standard can t be used with the Video9000 The third standard is SECAM and is used in France Neither this standard is supported by the Video9000 A basic version specially made for the GEX9000 It s based on KUN basic but all graphical and text commands are made for the GFX9000
5. properly Applications for disk basic can be very different and therefore many different fixing strategies can be followed Instead a general solution YOU CAN ALWAYS TERMINATE BY MEANS OF A HARDWARE RESET Finally it might be a good idea to change a function key for example F1 into the command OUT amp H6F amp H10 by typing KEY 1 OUT amp H6F amp H10 4CHR 13 RETURN Then you can always go back to the MSX 2 2 turboR text screen by pressing F1 24 10 Building the Video9000 into a pc box 10 Building the Video9000 into a pc box If you want to build the Video9000 into a pc box you can follow the strategy given below Open the Video9000 box by means of the three cross head screws at the bottom side but only remove the two black ones completely If there are any spacers pieces of plastic between the two PCBs that are not fastened anymore remove them Drill some holes through the bottom half of the box and mount the Video9000 by means of these holes at a suitable place in the pc box Extend the cable to the colour and intensity controllers in order to be able to move these controllers to for example the front side of the pc box Extend the video input and output connectors to the back side of the pc box if necessary NEVER REMOVE THE BOTTOM HALF OF THE VIDEO9000 BOX ANY GUARANTEE WILL BE LOST OTHERWISE It is also possible to use the upper half of the Video9000 box for mounting the Video9000 somewhere in

12. the V9990 processor must start with the same line too and both signals must draw that line at the same speed The circuit that synchronizes the V9990 with the external video signal is called a genlock Therefore to be able to superimpose and for digitizing holds the same the genlock circuit must be running enabled The genlock is controlled by bit 4 of port amp H6F as described in chapter 5 When this bit is 1 the genlock is enabled and the GFX9000 is synchronized with the video signal of the selected input RGB S VHS or CVBS if present Superimposing is only useful if the video scene is not completely covered by the graphical image Therefore the GFX9000 screen must be made transparent at certain places This is carried out by making the YS bit 1 provided that the YS enable bit is also 1 as described in chapter 5 in the paragraph About the YS bit Starting with the superimposer Type in the following program Power basic not installed 10 VIDEO9000 SUPERIMPOSE PROGRAM 20 ON STOP GOSUB 300 STOP ON Activate CTRL STOP function 30 9000 INITIALIZATION 40 OUT amp H67 0 Non overscan mode 50 OUT amp H64 6 OUT amp H63 amp H97 OUT amp H63 8 512x212 32768 colours 50Hz 60 OUT amp H64 8 OUT amp H63 amp HE2 Digitize off YS system enabled 18 7 Superimposing with the Video9000 70 OUT amp H64 14 OUT amp H63 0 Select palette no 0 80 OUT amp H61 128 OUT amp H61 0 OUT amp H

20. each dot of the screen has it s own value that represents its colour The V9990 can have a maximum of 15 bits 232768 colours per pixel Now a sixteenth bit is introduced that determines if the pixel must be shown or if it s transparent so that the external video source is visible through this one dot hole For example by setting this sixteenth bit bit no 15 at 1 for all dots within a circle the external video source is visible through this circle This sixteenth bit is called the YS bit and determines the transparency state of the corresponding pixel But not all screen modes of the V9990 use sixteen bits only the full colour modes When using the palette mode like MSX 2 screen 5 does each dot is given a palette number and this number refers to a colour that has been written in the palette table Because the value of the dot is not a direct colour but rather a reference to a colour in the palette table the YS bit has moved to this palette table For example Imagine that palette number 0 corresponds to colour 0 black and that palette number 1 corresponds to colour 992 bright red The palette table is then as follows 13 5 How to control Video9000 Palette Colour code Decimal number Green Red Blue colour value 0 0 0 0 0 1 0 31 0 992 0 dots at the screen black dots can be made transparent writing 128 amp B1000000 in the red column at row 0 This means t
