Downsampling

Click the Downsample toolbar button. A dialog box appears asking for a
downsampling ratio. This can be specified directly, or by entering the
desired image size. Click OK to downsample the image. The downsampling
algorithm includes a filter, so the boundary between the active and inactive
areas softens slightly. Zoom in and check that the correct areas are
transparent, and make corrections if necessary.
E.3.5

Saving the .osd File

Select File/Save As/OSD file from the menu. Saving is possible at any
time, and it is advisable to save the image often while editing is in
progress. The file may also be saved in .bmp format, but this file will not
contain transparency information.

Downloading a Logo Using OSD Loader

The Osd Loader is an application for transferring On-screen Display files to
the Encoder, and causing the images in these files to be overlaid on the
input to the Encoder. This enables logos to be superimposed on the
encoded bit-stream without an additional preprocessor.
The application runs on a PC with Windows 95 or Windows NT. A network
connection is required. The target Encoder's IP address must be visible
from the host PC.
The application uses the .osd file format for images. These can be derived
from Windows .bmp files using the OSD Creator application (see Section
E.2, Creating a Logo Using OSD Creator).

Using the OSD Loader

E.5.1

Start-up

Activate the application. The application attempts to connect to the last
known Encoder address. If the address is not correct, click the Abort
Transfer button and enter the IP address of the target Encoder. This can
be found on the Encoder front panel by selecting Setup/System/Remote
Control. To test the connection, click the Remove All button (you will be
prompted for confirmation). The communications box (at the top of the
screen) should read "Transfer Completed OK". Set the resolution mode to
576 if the Encoder is currently in 625 line standard or 480 if it is in 525 line
standard.
E.5.2

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.
