Microsoft has created a website where you can know all the information about HD-DVD authoring and also provided tools which can be used to author HD-DVD.

While the technology used to author HD DVD interactivity support far more advanced capabilities, the production process and workflow is similar to that for authoring standard DVDs.HD DVDs use HDi™ technology to provide advanced interactivity. HDi™is based on widely adopted Web technologies, such as HTML, XML, CSS, SMIL, and ECMAScript (JavaScript), therefore authoring in HDi™ is an easy transition for Web developers.

List of contents in the website are as follows:

• An introduction to HD-DVD authoring
• HD DVD interactivity jumpstart package
• HDi interactive sample code
• HD DVD interactive Authoring forum
• HDi related blogs from microsoft

Overview:
Surface is the first commercially available surface computer from Microsoft Corp. It turns an ordinary tabletop into a vibrant, interactive surface. The product provides effortless interaction with digital content through natural gestures, touch and physical objects. In essence, it’s a surface that comes to life for exploring, learning, sharing, creating, buying and much more. Soon to be available in restaurants, hotels, retail establishments and public entertainment venues, this experience will transform the way people shop, dine, entertain and live.

Surface is a 30-inch display in a table-like form factor that’s easy for individuals or small groups to interact with in a way that feels familiar, just like in the real world. Surface can simultaneously recognize dozens and dozens of movements such as touch, gestures and actual unique objects that have identification tags similar to bar codes.

Surface will ship to partners with a portfolio of basic applications, including photos, music, virtual concierge and games, that can be customized to provide their customers with unique experiences.

About Surface Computing:
Surface computing breaks down traditional barriers between people and technology, changing the way people interact with all kinds of everyday content, from photos to maps to menus. The intuitive user interface works without a traditional mouse or keyboard, allowing people to interact with content and information by using their hands and natural movements. Users are able to access information either on their own or collaboratively with their friends and families, unlike any experience available today.

Features:

Multi-touch display. The Surface display is capable of multi-touch interaction, recognizing dozens and dozens of touches simultaneously, including fingers, hands, gestures and objects placed on the surface.

Horizontal orientation. The 30-inch display in a table-sized form factor allows users to share, explore and create experiences together, enabling a truly collaborative computing experience.

Dimensions. Surface is 22 inches high, 21 inches deep and 42 inches wide.

Materials. The Surface tabletop is acrylic, and its interior frame is powder-coated steel.

Will Surface computing change the digital media interactive experience. I will be analyzing the benefits of using surface computing for Non-Linear Video Editing Applications and will it bridge the gap between linear and non-linear medium of interaction, user experience and creative freedom?
