Part 1 of this white paper presents an overview of the key technology blocks that make up the Intel-based IVI platform, as well as the challenges faced in optimizing and incorporating these into the platform.

Automotive manufacturers today face a tremendous challenge in trying to bridge the historically long development cycles of a vehicle to the ever-changing I/O and multimedia demands of the consumer. The main function of the car's entertainment system or the head unit is enabling a variety of functions like navigation, radio, DVD players, climate control, Bluetooth, and so on.

Further, with the promise of the connected car becoming a reality enabled through broad deployment of multimedia-capable mobile wireless technologies, the automotive industry sees an opportunity to deliver new value-added services to the consumer. However, with today's proprietary head-unit solutions they have limited ability to offer such services. A cost-effective solution to address this need is to use standards-based platform technologies that can take advantage of the huge ecosystem built around PC standards and consumer-oriented applications and services.

Introduction
We will start with the architecture of an IVI platform with a brief introduction to the platform stack and delve into each of the stack components, both from an hardware and software perspective; we will also examine their interdependencies. The theme of discussion for each of these technology areas is as follows:

Overview with usage models
- By car OEM and end customers
Challenges that:
- Were overcome in optimizing and enabling various technology blocks for an Intel-based IVI platform
- Remain to be addressed now and in the future by Intel Corporation, the car OEM, IHV/ISV/OSV, and academia for various usage models
Opportunities that present themselves to:
- Car OEM for product differentiation
- Third party software and hardware vendors to enable new markets-ecosystem enabling
- Academia for identifying areas of advanced research and technology development

An in-depth discussion follows covering the following technology building blocks for blocks for an Intel-based IVI platform:
