|Universal Media Player|
|This concept is based on the fact that data networks in the future will be all digital, packet based and will be sent to and fro between all-in-one devices, i.e.convergent devices. This integrated system will comprise of all kinds of data tranmissions - audio and video streaming via the internet, television signals, radio transmissions, voice (speech based) signals, fax etc. This will be in some sense convergence of all networking protocols to IP - Internet Protocol. We already have in our midst early forms of convergent devices - the mobile phone, the PDA and the likes.
So, my aim was to design a sort of a universal media player for a mobile phone. I worked on the Nokia mobile, Series 60 platform using Symbian as the underlying Operating System. The coding was carried out in Java Micro Edition (J2ME). The constraints were -
~~ Limited physical memory on device thus limited buffering
~~ Handling variable data rates available on all the common protocols like HTTP, RTP, RTSP etc, built on transport layer protocols like TCP, UDP etc.
We finally did the application using a double buffering operation, i.e. two player processes alternately buffering and playing data. We also looked into how the application could detect and differentiate between different data packet types.
