The diagram below shows
the differences between sending digitized video over the Internet in a non-streamed video
flow and and a streamed video flow. The planning formula for streaming video is: File Size vs. Bandwidth Size = Total Transmission Time & Video Image Quality
In the non-streamed video flow - the video files are usually uncompressed and very large. All of the original 30 frames per second of video data is retained within the video format which accounts for the large files. Sending large, non-streamed video files across a standard Internet connection of 28.8 modem could take an excessive amount of time. The image quality are at their best with this full video format. The penalty cost comes in terms of lost transmission time and streaming efficency.Streamed video files - uses different compression technologies to reduce the overall video file size by eliminating redundant video frames from the files, which in turn, reduces the total size of the streamed video files. Transmission of the reduced video (smaller) files are then able to be sent in shorter times over a standard 28.8 modem faster. The penalty cost is usually poorer image quality due to the loss of redundant frames. |
