What Is Software Defined Video over Ethernet (SDVoE)?

Andy Jimenez, vice president of technology at Anixter, explains what software defined video over Ethernet (SDVoE) is and what some of its key advantages are.

Transcript: What Is SDVoE?

Hi, I’m Andy Jimenez.

Data communications in local area networking applications have evolved over the last 30 years. Gone are the days of multiple disparate communications protocols that often required a variety of different cabling systems to function properly. Device communication today can be achieved via a single Ethernet protocol environment, operating over a standardized cabling infrastructure.

Much like VoIP and physical security systems, A/V applications can also take advantage of operating over an IP-based infrastructure. SDVoE is the leading system for low latency transmission of AV over IP. By leveraging the existing OSI layer model established for network communications systems, SDVoE builds on the suite of 802.3 and 802.11 standards and offers solutions for the full 7-layer OSI stack.

This includes:

  • Physical layer media such as structured cabling
  • An Ethernet data link layer
  • IP and IGMP network layer
  • TCP and UDP transport layer
  • SDVoE Session Management layer
  • SDVoE adaptive clock resychronization presentation layer
  • And SDVoE API application layer 

The advantages of SDVoE when compared to traditional A/V distribution systems include the following:

First, cost. Ethernet-based switches are widely available and do not require custom hardware configurations, which drive device port costs dramatically lower than traditional AV switching platforms.

Second, future-proofing. IEEE 802.3 standards support 10 Gbps data rates over structured cabling that facilitates the transmission of uncompressed 4K video streams.

And third, density. Increasing port counts due to converged applications are limiting available space within telecommunications rooms. With SDVoE, port densities of up to 48 per 1RU are achievable on many Ethernet switch platforms.

SDVoE promises to be very disruptive to the AV industry and will offer challenges and opportunities for legacy and new vendors. To learn more about this topic, read our TECHbrief and talk to your local Anixter representative.
