Excerpted from the website:
+
*Flash Player supports HE-AAC v2 which is an extension of AAC that uses Spectral Band Replication (SBR) and Parametric Stereo (PS) techniques to increase coding efficiency at low bitrates.

 +
===Advantages===
 +
*High video quality, resolution and low storage requirements
 +
*Improvement in the performance and quality of full-screen mode through the use of hardware scaling.
 +
*Optimizing the On2 decoder for decode performance and reducing blockiness.
 +
*Player cache reduces SWF size and download times
  
 +
===Disadvantages===
 +
*High Computational overhead
 +
**Present PCs dont have capability to process this information
 +
**Extra hardware acceleration is needed for performing In-loop deblocking, motion compensation, and inverse transform portions of H.264 decoding. ATI’s VPU (Visual Processing Unit)can be used as a solution.

Revision as of 00:06, 30 April 2009

Background

  • Web video can be defined as the video clip in digital format found on internet. As new websites focusing entirely on offering free video clip to users, there were tens of millions of video clips available online by mid 2006.
  • The use of internet video is growing very fast. Between March and July of the year 2006 YouTube alone grew from 30 to 100 million views of videos per day.
  • BBC has released BBC's iPlayer in July 2007 based on internet video. Source
  • Some file formats available in web video are Quicktime (.mov), Windows Media (.wmv), Flash Video (.flv), and MPEG4 files (.mp4) Source

Adoption

US Adoption

  • The number of viewers will rise from 114 million in 2006 to 183 million in 2011.
Source
  • MySpace tops both Yahoo and YouTube in Web Videos
Source
  • All major Internet companies involved in online video such as Google, Yahoo, YouTube and Microsoft use the Flash video format.
  • 97% of Web users can see instantly, hassle-free and without having to download any special software or plug-ins.
  • Flash Player installs are driven by content, and new releases of Flash Player take approximately 12 months to reach 90% penetration.There are approximately 8 Million Flash Players installed every day.

Product innovation: Flash Player 9

  • Flash Player 9 Update 3 Beta 2(Moviestar) supports H.264 video and HE-AAC audio and hardware accelerated, multi-core full screen video playback maintaining backwards compatibility by supporting On2VP6 video codec, in addition to the Sorenson Spark codec.
  • The system also contains new Flash Player cache for common platform components, such as the Flex framework, to reduce application sizes and start-up times.
  • Flash Player supports HE-AAC v2 which is an extension of AAC that uses Spectral Band Replication (SBR) and Parametric Stereo (PS) techniques to increase coding efficiency at low bitrates.
  • HE AAC enables the delivery of 5.1 surround sound at 128 kbps, consumer-grade stereo at 48 kbps, and excellent quality stereo at 32 kbps or below.

Technical details

Advantages

  • High video quality, resolution and low storage requirements
  • Improvement in the performance and quality of full-screen mode through the use of hardware scaling.
  • Optimizing the On2 decoder for decode performance and reducing blockiness.
  • Player cache reduces SWF size and download times

Disadvantages

  • High Computational overhead
    • Present PCs dont have capability to process this information
    • Extra hardware acceleration is needed for performing In-loop deblocking, motion compensation, and inverse transform portions of H.264 decoding. ATI’s VPU (Visual Processing Unit)can be used as a solution.

DRM

  • Flash DRM is a big deal. It's not something people like, especially because the allure of Flash is that it's a simple experience, but big studios want it.
  • MPEG LA's AVC Patent Portfolio License provides fair, reasonable, nondiscriminatory access to essential AVC/H.264 patents owned by many patent holders as an alternative to negotiating separate licenses.
  • Streaming H.264 video or AAC audio into the Flash Player by 3rd party streaming servers will be allowed only by proper licensing.
  • Commerical use of H.264 and AAC streams can be done using proper licensing (ie broadcasting fees).
  • On2, the company behind the codec for Flash Video, announced that they are actually partnering with Widevine to provide the DRM solution. The DRM protection may include content integrity protection and identity-based content protection.Source-zdnet

Summary of licencing terms for H.264

Upcoming features

  • H.264 implementation in Flash Player will support alpha channel in upcoming player (probably flash player 10). Alpha channel is used to maintain background quality in images from frame to frame.
  • Multichannel playback will be come in advanced versions of flash player

Trends from patents

  • Video conferencing, Online video sharing and Online video advertising are the active areas for IP activity.
  • Bit rate and resolution are the two main elements which affect the quality of the video played online. Compression or coding of the video effects the video.
  • Single-loop spatial scalability coding, Network congestion detection and control,Editing a low-resolution media asset to generate a high-resolution edited media asset etc are some of the hot trends in improving video quality.
