Blue Ray is the future standard for HD. 95% of the players in the US are currently PS3. The players are network aware so that you can interact with online. They use BDJ (rather old Java similar to J2EE mobile Java) and the current versions is 1.1 which means that the studios have abandoned early adopters but at leas late hardware adopters will have a great user experience. All the £1000 player adopters will, i'm afraid, have to upgrade!
Blue Ray authoring is an art which our multimedia arm, with a long history in software development, video and CDROM/DVD authoring has committed to. It is the future. However Blue Ray development follows a rather different profile to these older technologies. For instance, it's hard to preview to your client as until you've written 95% of the code you won't have anything decent to show! So the client may be used to DVD taking a few days or CDROM taking a week with a preview after a few days. Blue Ray will take longer and it's only toward the end of the project that you'll see the result actually functioning.
The flexibility of the platform and the quality of the video playback make this the future of HD distribution on disc for western economies. It has so many uses beyond film and TV disc based distribution. Due to it's Java authoring environment Blue Ray Games development is possible mixing a hybrid of video, server based communication, content and game elements.
Other examples of potential solutions are HD video playback in car show rooms and exhibtions that automatically update their content, Web based presentations (i.e. like a web based video conferencing box with slides and live audio/video streams), chat and instance fanbase communication, buy the disc , join the group.
Setting up the studio is expensive, building the in-house expertise is not quick and you should start with a good base. And what of there are Test plans, QA and Qualification of your code and disc. We are building a center of excellence in Testing QA for Blue Ray as well as other other development team (.NET, Web, Java, CD, DVD, Content). Watch this space!
