Introduction

35.1.2 Features

The VPIF is designed to support the following features (note that some device designs may support
reduced features because of system-level performance limitations):
• ITU-BT.656 format
• ITU-BT.1120 and SMTPE 296 formats
• Raw data capture
• VBI data storage
• Clipping of output data (to eliminate FFh and 00h values)

35.1.3 Features Not Supported

The following functions are not supported:
• ITU-BT.601 format
• Separated synchronization format (requiring vertical sync, horizontal sync, and field ID signals
independent of the pixel data) is not supported (except for the raw data capture mode)
