Average US Broadcasters Streaming at 837 kbps Total Data Rate

I track the data rate and video configuration used by broadcast sites since they indicate the types of streams that their mass market audiences can retrieve and play, and also the quality of streams that web video consumers are used to viewing. In my latest survey, the average video configuration was very close to 640x360, with a combined audio/video data rate of 837 kbps (758 kbps video, 79 kbps audio). This computes to an average bits per pixel value of .115. If videos posted on your site are lower than these figures, you're probably being unnecessarily conservative.

Configuring Your Streaming Video (for Newbies)

Configuring your video streams properly requires an understanding of three concepts; data rate, resolution and frame rate. In this article, I'll define these terms and discuss the influences that impact your choices for each parameter. Then, at the end, I'll walk you through a decision matrix designed to help you choose the optimal parameters for your streaming video.

While this is designed for newbies, the concepts discussed will be valuable to all streaming producers, particularly the information regarding the average bitrates used by broadcast, business-to-consumer and business-to-business sites. Sound interesting? Well then, click over the main article to get started.

Stat of the Week: HTML5 Desktop Market Share at 58.1% Max

According to the latest statistics from NetMarketShare, the current penetration of HTML5-compatible browsers in the desktop market is 58.1% maximum. To completely serve these browers, you'd have to encode in three formats, with 47.5% of desktops compatible with WebM, 44.1% compatible with H.264, and 8.3% compatible with Ogg (this is the Firefox 3.6 crowd). Click over to the main article to see how I calculated these numbers.

html5 vs flash on android.png

By now you've heard that Adobe will discontinue the development of the Flash Player on the Android platform, stating in part that "HTML5 is now universally supported on major mobile devices, in some cases exclusively. This makes HTML5 the best solution for creating and deploying content in the browser across mobile platforms."

Boy, they weren't kidding. I was interested to learned Flash's penetration on the Android platform, so I surfed over to www.riastats.com, and selected Android in the OS list box on top. In the main story I detail my findings.
