1. Introduction
The Philips ISP1581 Hi-Speed Universal Serial Bus (USB) MPEG2 Encoder Reference Kit is a
development tool that consists of an MPEG2 encoder demo board, firmware source code for the
onboard microcontroller, and a complete set of documents. This kit guides you in how analog
video signals from various sources (S-Video or composite signal) are converted to digital video
signals, which are then compressed to an MPEG2 bitstream by the onboard MPEG2 encoder
chip. The bitstream is transferred to the PC through a high-speed USB pipe. This kit is very
suitable for video capture card applications and digital video (DV) applications.
This document explains the use of the demo board in terms of jumper settings and connector
pin assignments. A basic board testing procedure is also provided.

3. Connection Diagram
To perform a functionality test, an Audio/Video (AV) source device is required. Its audio and
video output signals should be connected to the audio and video input jacks of the demo board,
respectively. See Figure 3-1.
