Extron electronic GSS 100 manual Features, Approximate Image Space for BMP Files

User-selected images, including the test patterns, can be uploaded to the GSS via its Ethernet port using HTML pages built into the GSS. The pass-through RGB input and the output are via female BNC connectors.

The GSS provides 16 MB of RAM for storage, providing room for up to 17 uploaded bitmap images. The number of images that the GSS can accommodate depends on the resolution of the images. Table 2 shows the number of BMP images that the GSS can accommodate, based on several common resolutions.

Table 2. Approximate Image Space for BMP Files

Resolution	640x480	800x600	1024x768	1280x1024	1400x1050
Size	900 kB	1400 kB	2400 kB	4000 kB	4400 kB
Image space	17	11	6	4	3

NOTE: Because of the variable compression schemes for JPG images, there is no reliable

method to calculate the number of JPG images that the GSS can hold.

• Progressive JPG images are not supported.

• Bitmap (BMP) images must be formatted as 24-bit RGB.

The graphic still store is housed in a rack-mountable, 1U high, half rack-width metal enclosure. The internal 100 VAC to 240 VAC, 50-60 Hz, 15-watt, power supply provides worldwide power compatibility.
