1 Introduction
This document details the Media Expansion card key benefits and operation. It is intended for a
technical audience interested in learning about Media Expansion card architecture.
Media Expansion cards, formerly known as ADD2+ cards, provide flexible digital display and
video-in capabilities on a single add-in card. The Intel® 945G Express Chipset will be the first
Intel chipset to support Media Expansion cards. The Intel® 82945G GMCH has an integrated
graphics device (IGD) with dedicated multimedia engines delivering high-performance 3D, 2D,
video, and display capabilities. The GMCH also has the flexibility to use an external graphics
accelerator through its x16 PCI Express* interface. When an external graphics accelerator is not
used via the x16 PCI Express connector, the Media Expansion card may be used to provide digital
display and video-in options.

Intel® 945G Express chipset
Media Expansion cards are available from many third party add-in card vendors. Media
Expansion cards allow the functionality of two or more discrete PCI Express cards to be
combined into one single card. For example, if an OEM wants to use a PCI Express based TV
tuner add-in card and another PCI Express based video card with TV-Out capability, then the
functionality of these two discrete add-in cards could be provided by a single Media Expansion
card with the 945G Express chipset. This flexibility allows OEMs to lower overall system costs.
Media Expansion cards are also ideal for small form factor designs where there is only one x1
PCI Express slot in the system. Since Media Expansion cards allow for the functionality of two or
more discrete PCI Express cards to be combined onto one card and use the x16 PCI Express
connector, this provides more solutions for system integrators of small form factor systems with
an available x1 PCI Express slot.
