Studio Video over IP has become the most talked about topic within the broadcast space. With the surge of interest, plenty of information has become available, such as standards recommendations, disparate solutions, and solution based organizations working together to streamline the transition to Video over IP.
This resource section should serve as an outlet to explain the latest in complete Video over IP solutions. We hope that this will reduce the confusion and allow customers to get a grasp on what's available or in development.

Video over IP Comparison
What you will notice from the chart is that a majority of the available options are not complete solutions, some lack compression, forward error correction, control, plug and play setup, or use with commercial off the shelf switches.

4K is needed today in a production environment. Of the available solutions only two offer compression schemes (Sony LLVC and Tico) for visually lossless video transport.
The current transmission bandwidth of IP networks is 10G, which can carry up to three uncompressed HD signals, but is not enough to carry one uncompressed 4K signal. Recognized as Mezzanine Compression, this technology is able to reduce the video bitrate (bandwidth) to allow 4K over 10G networks. A key benefit is the economical advantage to the 25G networks required to handle uncompressed otherwise.
Forward Error Correction (FEC)
Live video transport in IP networks introduces the possibility for packet loss, which can have serious consequence given the circumstances of the quality required for broadcast transmission. FEC is required to guarantee delivery of packets in transmission without requiring redundant data streams, enabling immediate recovery of lost packets.
Control and Resource Management
Allowing users to intuitively connect, monitor, manage, and control devices within the IP network is crucial.
The 6 components of Control and Resource Management are:
- Registration & Discovery - Enables devices to identify themselves to a registry
- Connection Management - Enables essence routing
- Device Control - Creates a common way to adjust settings of a device
- Network Control - Enables larger control systems to communicate with the IP subsystem
- Configuration & Monitoring - Enables system-wide configuration and system monitoring
- Authentication and Access Control - Enables proper permissions and security measures
Sony's IP Live System Manager (LSM) provides all six of the above capabilities.
Customers want their IP Gateways to interoperate seamlessly. Endpoint Validation is the only ay to guarantee this. Sony NMI is the only current solution to offer End Point Validation for all new products, guaranteeing full interoperability out of the box.
It is generally agreed that SMPTE 2110 is the future of Video over IP for the studio. Manufacturers are rallying behind this standard to create products that will work seamlessly together in an IP based studio. It's worth mentioning that 2110 isn't just a single standard, but a suite of standards.
- 2110-10: System Timing and Definition
- 2110-20: Uncompressed Active Video
- 2110-21: Timing Model for Uncompressed Active Video
- 2110-22: Compressed Video Formats *(Tentative)
- 2110-30: PCM Digital Audio
- 2110-31: AES3 Audio Formats
- 2110-40: Ancillary Data
- 2110-50: Interoperation of ST 2022-6 streams
Ok, that sounds amazing! Give me SMPTE 2110
Woah, slow down, SMPTE 2110 isn't quite ready. The current progress is as follows (as of May 2017)
- Video/Audio/Meta interoperability demonstrated (uncompressed HD only)
- Initial Registration/Discovery/Control work looks promising, but more work is required
- No clear Compression solution to support 4K over 10G
Organizations such as SMPTE, AIMS, VSF, EBU, AMWA, etc., have been hard at work to streamline the transition to Video over IP. Significant progress has been made in the past year to ensure that the proposed SMPTE 2110 standard ecosystem will meet the needs of all stakeholders. Nextera will have solutions available as soon as the standards are ratified.
JT-NM and NMI Roadmap
When should we expect the complete ecosystem?
The Joint Task Force on Networked Media (JT-NM) released a roadmap, which shows the progress of standards and specifications, how the underlying technologies are expected to evolve, and when it is expected to be widely available to build interoperable multi-vendor systems.
This roadmap has been modified to include the Sony IP Live System Manager (LSM), which bridges the gap from today’s deployed and fully operational Networked Media Interface (NMI) system to the standards based system by providing a complete unified control system that will work equally well with both systems.
Nextera IP FlexCore - 2110/NMI
As an active member SMPTE, VSF, and AMWA, Nextera fully supports the SMPTE 2110 family of standards. Since a standards based Studio Video over IP system is not quite here yet, we realize there are customers who are ready for a solution they can implement today.
We recommend a hybrid solution that provides a technology bridge between today's NMI system and the upcoming 2110 system. Manufacturers can use Nextera’s FlexCore to select between a 2110 or NMI stream on the fly, all managed by a unified control system. Details of this hybrid approach are as follows:
- Live System Manager (LSM) control system is available today and will be compatible with BOTH NMI and 2110
- Hybrid Encoder transmits 2110 for HD, NMI for 4K
- Hybrid Decoder auto-detects stream format
This solutions leverages Sony's IP Live Ecosystem today with the interoperability of 2110 once ratified. The solution starts with NMI, then moves HD to 2110 (when available) retaining NMI for compressed 4k and retaining the Sony LSM Plug and Play control system. Below is a proposed workflow to illustrate the transition to a unified Studio Video over IP ecosystem.
