CDN VOD 4OD CostofStreaming

  • Some analysts question whether VoD can be as profitable as broadcast TV. The dual costs of piping internet video into the home and licensing content from producers - both paid out on a per-view basis - "may call into question the level of profits that can be made in the long term" from VoD, says David Cockram of Oliver & Ohlbaum, a media consultancy. "More people are taking more of the pie."
  • Broadcasters already have to pay companies providing "content delivery networks" to ensure their on-demand programming reaches viewers in good quality and without loading-time delays mid-video. Every time a programme is viewed online through their VoD services, the BBC, ITV, Channel 4 and other broadcasters pay a CDN provider such as Akamai, Level 3 or, soon, BT.
  • Today, one half-hour programme costs between 2p and 5p to stream through a CDN every time it is viewed. That may not sound much, but with the BBC iPlayer serving up almost 60m TV shows in November, a broadcaster's CDN costs could already exceed £1m a month.

  • Streaming video requires access to a streaming media server.
  • When a video streams, it is being sent via UDP protocol to a player on the end users compter. The user will have the ability to fast forward or rewind the video.
  • video isn't being downloaded to the end users computer so it is less likely that the content will be stolen

    The biggest disadvantage of streaming over progressive download is if the user watches the same video over and over you will pay for the delivery of it each time. Videos are also streamed at what ever bit rate they are encoded at. Keep this in mind when creating HD quality video. 8Mbps video may sound and look great, but most homes can't sustain an 8Mbps connection. If you have really high bit rate video, consider delivering via HTTP. Most web hosting providers or Content Delivery Networks (CDN) will have streaming media servers available to use. Historically, Flash video was more expensive to deliver than other forms. Recently prices have compressed and you will find that it costs about the same to deliver Flash or Windows Media files. In the past I would have said if your video is more than 10 minutes in length deliver it via Stream and less do progressive. Since prices

  • video delivery mechanisms
  • three widely used ways
  • For longer videos, the downsides start to impact playback too much
  • ...24 more annotations...
  • Progressive Download is the most widely used
  • easiest to implement
  • Progressive Download is supported by Flash, HTML5 browsers
  • bandwidth is wasted on data downloaded but not watched
  • simplicity of Progressive Download also has its downsides.
  • inability to change the quality of the video mid-stream
  • Progressive Download, RTMP/RTSP Streaming, and Adaptive HTTP Streaming
  • Progressive Download works fine for short clips (a few minutes).
  • RTSP/RTMP Streaming
  • RTMP/RTSP Streaming is widely used by professional media organizations like Hulu
  • if the connection speed drops below the minimum bandwidth needed for the video, playback will be continuously interrupted.
  • most widely solution is used is RTMP (Real Time Messaging Protocol)
  • HTML5 does not include a dedicated streaming protocol, nor does the iPad/iPhone
  • RTMP streaming can change video quality mid-stream
  • allows for optimal playback quality in the fullscreen and WiFi/3G scenarios
  • only deliver the frames of a video the user is currently watchin
  • has specific server and protocol requirements, which makes it less accessible and adds significant complexity and cost
  • Adaptive HTTP Streaming is a fairly new streaming format
  • Adaptive HTTP Streaming works by storing your videos on the server in small fragment
  • daptive HTTP Streaming leverages standard webservers, it is supported by webhosters and CDNs alike.
  • none of the Adaptive HTTP Streaming implementations work with regular MP4 files.
  • Adaptive HTTP Streaming will likely become the single video streaming method over time
  • live streaming is not possible,
  • o data is downloaded in advance and data a user has seen is immediately discarded.
