AccuStream Auto-SYNC Wizard Step 2: Adjust Left/Right Framing
for SDTV Connections
The next step is to adjust the left/right framing of the image. The left edge is set first and then
the image width. The left edge is set by the value of the Horizontal Back Sync (HBS), which
represents the period between a horizontal sync pulse and the start of active video. The image
width is set as the number of pixels per line.

Framing adjustments require an image that has a non-black background that extends across the
entire image. The SMPTE pattern is recommended.
The Horizontal Back Sync (HBS) is adjusted in the standard way. Increasing the HBS moves the
image to the left. Set the HBS so that the image’s background extends fully to the left of the
viewing window.
