Download an .osd File

Choose an On-screen Display file with the Choose File button. You will be

prompted for a file with an .osd extension. The image will be displayed in

the OSD File box.
Position the image on the screen by dragging the white cursor box around

the main placement window. The position can also be adjusted by editing

the co-ordinates boxes.
A logo can be overlaid anywhere in the digital active picture. When a logo

is positioned in the main placement window, the co-ordinates are shown

for the top left corner of the logo. The co-ordinates that the Osd Loader

uses include an offset. Figure E.6 and Figure E.7 illustrate how these

co-ordinates relate to the active picture.
When the logo is correctly positioned, click the Download button.

Transferring Data… appears in the communications box. The image will

be displayed in the main window. Wait for Transfer Completed OK to

appear in the communications box. After a short delay, the image should

appear on the output from the Receiver.
If the Auto Store box is checked, when the logo is downloaded to the

Encoder, it will be stored in Flash memory and will still be present after the

Encoder has been powered off. Only one logo can be stored in Flash at any

time. The maximum logo file size that can be stored in Flash is 65 279

bytes. The file size will be affected by the size of the logo and its

complexity (number of colours and levels of transparency). For example

this is roughly equivalent to a logo 200 x 145 pixels with 256 colours

(62 567 bytes).
If the Auto Store box is left unchecked, the downloaded logo will be

stored in volatile memory and will be lost when power is removed from the

Encoder.
