Comparison between YouTube and Traditional Media
Comparison• Media Resource Size• Update Frequency (incl. whether updated contents are relevant to recent news)• Integrity of Source of Information
Media Resource Size• YouTube: Gigantic (in April 2010, 13 billion videos)• Traditional Media (Newspaper, TV/Radio Stations): – Usually come from recordings, videos, photos – Dynamic websites
Introduction• Traditionally, – need to download the video to your computer before playing it – cannot play it until you finish downloading the whole video – if the connection is broken, you may need to download the whole video again from the beginning
• In YouTube, – need not to download the whole video before playing it – play it when you are downloading the video• This technology is called “Streaming”
What is Streaming?• Technique for transferring• Processed as a steady and continuous stream• Start displaying the video before the entire video has been downloaded• Requested data flow as stream of digital bits
What is Streaming?• Small buffer space is created on the client’s computer• Buffer is full, the video starts to play• The file plays, it uses up the information in the buffer• It is playing, more data is being received• download >= play => play smoothly
Advantages of using Streaming• Saves downloading time of large video• Slower systems can take advantages• Real time service
Disadvantages of using Streaming• download >= play => play smoothly• Internet bandwidth is too low =>not steady• Maintenance cost of streaming server is relatively costly• Packet loss may occur
What does we need for Streaming?• Media Player• Decompressed and plays it• Integral part of a browser• Downloaded from the software maker• YouTube, we need Adobe Flash Player
Revenue Sources• Direct Approach – Users buy services/products provided by the website – Money is earned directly $ Your Users Website• Indirect Approach – Users go to another websites via your ads – Money is earned indirectly $ Your Another Users Website Websites
YouTube: Indirect Approach• Difficulties to make money – depend on whether the user is targeted customer or not – users are anonymous in the internet in most cases – the need of the users changes every time Difficult to make money in short term
Other Things behind• Number of edges of every users are limited• Culture: More users’ paths are overlapped Reflect societies’ conditions (eg: developed/developing)• Old nodes are disappeared and More new nodes Internet changes rapidly!!!
