60% Lower Bandwidth, 'Video Anywhere' - Digital Barriers TVI / EdgeVis

Author: Brian Karas, Published on Oct 28, 2016

Streaming video over low bandwidth, wireless connections often results in stalled video, broken up video or significant video delays.

But Digital Barriers says their TVI CODEC (not to be confused with the HD Analog format), which is being re-branded as EdgeVis, can dynamically adapt to changing network conditions to deliver video where other CODECs fail.

In a conversation with Digital Barriers, we examined specific details on this CODEC, how it works, and what the limitations are. Our findings are inside this report.
