This paper addresses technical and business issues relating to delivering multimedia content to automobiles using Wireless Local Area Networks (WLANs). Content delivery in the home and hot-spots are discussed. Two key delivery mechanisms - downloading and streaming are addressed and solutions proposed to reliably deliver content over the WLAN infrastructure. A key factor is the use of efficient video compression. Recent advances in video compression will be introduced and issues relating to encoding and decoding complexity will be discussed. Solutions to security and content protection are also addressed. The paper concludes with a discussion of possible business models. Security and content protection solutions can range from renewable hardware solutions such as smart cards or software-based solutions. The nature of the solution depends on the delivery mechanism and the nature of the content. The authors believe strongly that content distribution to automobiles using WLANs has strong potential. The decision of an automobile maker to introduce a WLAN device with storage, appropriate support for video decoding and security tools and relationships with network access providers is expected to be the key enablerfor this business.
