From my limited understanding, SD cards and DivX are different to the Avot offering.

SD cards are just another form of video cassette or DVD, buy the movie, plug in and play.

DivX videos require a DivX player.

The Avot engine dynamically transcodes video assets as they are being request by the end-user. The content provider doesn’t have to create a separate, pre-transcoded version of the video in anticipation of a request. Avoiding the need to pre-ingest videos frees up valuable disk space and server resources. Avot formats and transcodes the same web video asset in a fraction of the time that standard transcoding requires.

Finally, Avot detects the users network type, network conditions, and device type. This allows the Avot engine to adjust the bit rate of the video steam to optimize the viewing experience. Avot stream controller technology throttles packet delivery to avoid any image stuttering or freezing on the device side. The result is a smooth, satisfying video viewing experience.

It would appear Avot goes beyond both SD cards and DivX.

Be well
