Technology

DINA™ is the only state-of-the-art platform solution in the world that can deliver on-demand mass data to mass audiences

Able to serve millions and millions of on-demand customers without breaking your wallet or the network

Over 95% savings on both system cost and bandwidth requirement comparing to unicast system

First impression – mass-scale VOD service

Codec independent

DINA™ is a distribution methodology rather than a compression technology – hence one can stream CBR / VBR MPEG-1/2/4, H.264, or even HDTV when it comes along

Worldwide patented and patent pending technology

Traditional delivery Unicast

Private channel to each user Expensive capital investment

e.g. each server handles 500 users → 2,000 servers to handle 1M users

Expensive running cost Provision bandwidth for each user Easily >1,000Gbps network bandwidth for 1 millions users

Un-scalable model – increase users and one has to increase bandwidth and server resource

Dimensioning leads to User blocking – unacceptable Sacrifice of hottest content - unacceptable

Pure Multicast / Broadcast Nothing more than another traditional TV channel

Problem with Unicast Delivery Variable cost business model

When the user base grows More and more capital investment More and more bandwidth requirement

Undesirable (bad) business model

System dimensioning sacrifices the hottest contents Marketing wants

the hottest contents (e.g. Lord of the Rings) in order to grow subscriber base

No user blocking / no system dimensioning Engineering forbids hottest content

Avoid system overload

Dilemma Build a humongous system first? Settle for a small market?

piracy issues
