Inputs considered to have 4:3 aspect ratio are:

• Computer Graphics signals with a 4:3 aspect ratio appearing on the DVI and Analog

RGB inputs

• SDTV signals (NTSC and PAL derived) appearing on the Composite, S-Video, and

Component inputs

• SDTV signals (NTSC and PAL derived) appearing on the SDI input

• SDTV signals (NTSC and PAL derived) appearing on the HDMI input

Inputs considered to have 16:9 aspect ratio are:

• Computer Graphics signals with a 16:9 aspect ratio appearing on the DVI and Analog

RGB inputs

• HDTV signals (480p, 720p, 1080i, 1080p) appearing on the Component input

• HDTV signals (480p, 720p, 1080i, 1080p) appearing on the SDI input

• HDTV signals (480p, 720p, 1080i, 1080p) appearing on the HDMI input

The five aspect ratio treatments, Standard, Full Screen, Zoom, Anamorphic, and Stadium are

intended to achieve different aspect ratio objectives, and therefore behave differently depending

on which input and output aspect ratios are currently selected. The Aspect Ratio objectives are

the following:

• Standard: always displays the correct aspect ratio of the input picture; adds black bars at

the top and bottom or sides of the picture to achieve this objective

• Full Screen: always fills the screen with the complete picture; linearly distorts the picture

to achieve this objective

• Zoom: always fills the screen with the correct aspect ratio of the input picture; crops the

picture’s top and bottom or sides to achieve this objective

• Anamorphic: intended to handle the specific case of 16:9 aspect ratio anamorphically

encoded into a 4:3 aspect ratio signal (e. g. an NTSC DVD encoded with a 16:9 picture

• Stadium: intended to handle the specific case of a 4:3 input aspect ratio and 16:9 output

aspect ratio

Table 5 to Table 8 present the five aspect ratio treatments over the four different combinations

of Input Aspect Ratio and Output Aspect Ratio.

TheaterSync is intended for Widescreen processing, the 1280 x 1024 SXGA is not a frequently encountered case.

Input of 1280 x 1024 will be treated as a pillar boxed 4:3 signal (i.e. it will have narrow black bars on the Right and

Left); aspect ratio of the picture content will be undistorted.
