<ソーシャルテレビ> オペラを活用したフィリップスのネットTV上のスエーデン不動産企業のアップスデモ


珍しい記事と映像ですがスエーデンの不動産業者SvenskfastはiPhoneアップスやWebサイト構築で数々の賞を受けた企業です。そしてその不動産業者Svenskfastがオランダ企業フィリップステレビのコマーシャル用テレビアップスを開発して「我々は先進技術に一番乗りする企業だ!!」と発表しています。なお、スマートテレビ用のミドルウエアはオペラのものです。オペラはテレビ組み込みブラウザーを開発しており、その横にブラウザー連動でアップス管理とストリームの仕組みの下、CE-HTML standard together with CSS and javascriptと言う条件のテレビアップス用プラットフォームを提供しています。
 尚、アップスはAvantime Group が実施しました。
 Svenskfast, YouTube and SLがスエーデンで初めてフィリップスのネットテレビに対応した企業ですが、スエーデンのフィリップスのポータルからダウンロードされるようです。(2009年7月末の記事です。これは驚きです。)

This time they are the first real estate company in the world to join Philips‘ new NET TV initiate. Owners of a NET TV enabled Philips TV can now find their dream house, apartment or vacation house sitting comfortably in their sofa!

So what is NET-TV, how does it work? A NET TV enabled device has a built in web browser developed by Opera, and features a portal developed and maintained by Philips. All applications are web based, built using the CE-HTML standard together with CSS and javascript. This is really awesome because it doesn’t require additional skills or development tools to build an app unlike building an app for the iPhone. Philips do provide an SDK with a TV emulator and CE-HTML/CSS validator, but I would recommend buying a NET TV enabled TV for development. In our case, the NET TV app is built as an extension to the existing website, resulting in the worlds first NET TV enabled EPiServer site.
Developing a NET TV site/app has a unique set of challenges compared to building a standard computer browser site:

Developing a NET TV site/app has a unique set of challenges compared to building a standard computer browser site:
* The TV screen itself is a challenge: it has a set resolution of 1280×720 with no scrolling possibilities in CE-HTML mode (it does when browsing normal html sites however). The end user is also sitting much farther away from the screen than a traditional PC screen so all elements must be big and easy to read/understand.
* There’s no mouse or keyboard which makes user input a bit of a hassle. Therefor the user interface must be simpler and require less input than a traditional web site. We decided to keep input at a minimum by using the keypad to interact with functions.
* Naturally the TV doesn’t posses the processing power of a standard computer (my model has a 300Mhz CPU of an unknown brand), JavaScript animations such as what jQuery is capable of doesn’t run smooth, timers should be avoided in general.
Although it features a 100Mbit network interface as well as a wireless network connection, images and objects just don’t download as fast as a traditional PC. Optimizations are key to create a responsive and fun to use application.
* The color range on the TV doesn’t match a PC monitor. Colors can look very different on the TV and gradient images don’t work well at all. Philips provide a tool for crunching images to fit the TV but gradient images especially doesn’t look good at all.
