Introduction
Digital  technologies  have  made  a  significant  difference  to  our  life.  Digital  contents  will  be  the  next  wave  that  changes  our  life.  For  example,  over  the  past  decade,  many  people  got  used  to  using  mobile  phones.  Some  of  us  even  have  two  or  more  mobile  phones.  Today,  mobile  phones  are  designed  to  take  pictures  or  listen  to  MP3.  Some  mobile  phones  even  have  color  screens  that  can  play  multimedia  games  or  watch  video.  This  is  just  a  simple  example  that  digital  technologies  have  changed  our  life  in  many  ways.

Let’s  take  a  closer  look at the trend in Silicon Valley after the past three-year downturn. High-tech giants (such as Intel, Microsoft, Hewlett-Packard, Apple, etc.) tout digital entertainment as their next big buzz. The buzz is about iPod or portable media player, rathe ... Full Story ...
