Setting up a DVD source

1.	If you are using a digital display, such as an LCD or DLP projector, use the
	alternating pixels test pattern as a reference to adjust the phase and dot clock
	on the display devices. Proceed to step 3.
2.	If you are using a CRT display, use the cross hatch test pattern as a reference
	to converge the display.
3.	Set the ISS to output either the crop test pattern for 4:3 video or the
	appropriate aspect ratio test pattern. Use the display’s positioning controls to
	position the image so that you can see all sides of the test pattern on the
	display.
		For the best results of this optimizing procedure, do not use the ISS’s center

		controls to position the image.
4.	Select an input. Use the ISS’s size and center functions to fill the crop or
	aspect ratio test pattern.
		If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio

		before sizing the image using the ISS’s size function to correct the aspect ratio.
		See Setting up a DVD source below.
		When sizing and centering a letterbox movie video source, increasing the

		brightness on the ISS makes it easier to see the top and bottom of the active
		video.
5.	If the input source is RGB, use the horizontal and vertical detail adjustments
	to increase the sharpness.
6.	For S-video and composite video inputs, set the ISS to output blue-only
	video and to output the Color Bars test pattern. Using the blue Color Bars as
	a reference, use the ISS’s color and tint controls to adjust the video’s color and
	tint.
7.	For RGB video inputs, set brightness and contrast levels. See Picture
	adjustments, earlier in this chapter.
8.	Save this setting into one of the user memories using the User Presets menu.

To get the best results when using a DVD as a video source, Extron recommends that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3. Because all DVDs are mastered as 16:9, having them set up for anything else causes the player to internally scale and compress the signal. The DVD player’s scaling and compression defeats the advantage of having 3-2 pulldown detection in the ISS.

All sizing adjustments to correct aspect ratio should be done using the ISS.

To change the output aspect ratio of most DVD players:

1.Enter the DVD player’s setup or action menu while the disc is stopped.

2.Select the 16:9 aspect ratio.

ISS 408, ISS 108 specifications

Extron Electronics is renowned for its contributions to the audiovisual industry, providing high-performance devices that meet the demands of professional environments. Two prominent products in their lineup are the ISS 108 and ISS 408 image scaling switchers, which are designed to enhance the management and quality of video signals in various applications.

The Extron ISS 108 is an 8x1 image scaling switcher that allows users to seamlessly switch between multiple video sources while ensuring high image quality. One of its main features is the ability to support a variety of video formats, including resolutions up to 4K. This versatility is crucial for applications in education, corporate settings, and events where different video sources may be required.

In terms of technology, the ISS 108 is equipped with advanced image scaling capabilities that improve the visual quality of the content being displayed. The device utilizes Extron's patented Vector 4K scaling technology, which enhances the clarity and detail of the images while maintaining the integrity of the source material. This technology is invaluable in environments where every detail matters, and it ensures that presentations are delivered at their best quality.

The ISS 408, on the other hand, takes the capabilities of the ISS 108 and elevates them further by offering 4x1 switching capabilities. This enables users to connect up to four video sources, giving them more flexibility in content management. The ISS 408 also supports 4K video resolutions, further solidifying Extron's commitment to delivering high-quality solutions.

Both models are designed with user-friendly interfaces, allowing for easy operation and integration into existing AV systems. They offer extensive control options, including RS-232 and Ethernet, enabling users to incorporate them into automation systems and control environments efficiently.

Another important characteristic of the ISS series is their built-in security features, such as password protection and lockout modes, which are essential for maintaining the integrity of sensitive content being delivered in corporate or educational settings.

In summary, the Extron ISS 108 and ISS 408 provide powerful solutions for image scaling and video switching. With advanced technologies like Vector 4K scaling, robust connectivity options, and intuitive control interfaces, these devices stand out as essential tools for any professional audiovisual application. Their focus on quality, flexibility, and security makes them ideal choices for enhancing video presentations in various environments.
