Had to do some R&D on TV applications a long ago.I finally concentrated on Tru2Way technology which is emerging,Brand name for opencable specifications.OpenCable is a set of hardware and software specifications under development in the United States by CableLabs to "define the next-generation digital consumer device" for the cable television industry.Tru2Way is developed by Cable labs.
Previously there is another technology called MHP(multimedia home platform) which is a decent success in UK.Then an Us company CableLabs started working on this Stream ..finally it is Tru2Way.The set top boxes in Us are bit different from rest of the world.Tru2Way is spreading among US.
Comming to the technology...what is this technology?why we are using this technology?what are the other technologies in this category?...these are some of the questions raised.....
Basically for a TV application the user cant interact with the cable operator ie there is no 2 way communication.But the applications which are developed by Tru2Way can have an interaction with the cable operator....confined by the application.Suppose a reality show is going on.You have to poll the contestant through SMS,but by using this technology we can directly poll to a contestant through remote.this is a sample application.we can develop a lot more.
This field has to be improved a lot.As far as i observed we are not able to input the characters i.e the user can only generate events.
The apps devoloped on this technology are installed on the Set Top Boxes.It uses java Tv API for network issues.
If you are interested in this technology first thing is to visit http://www.java.net and where you can find forums....for a lot more discussion.
