Video over IP Resources
Studio Video over IP
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. If you would like to learn more, or receive a free short introduction to Studio Video over IP, please don’t hesitate to reach out to us at [email protected] for more information.
SMPTE ST 2110
SMPTE 2110, What is it and Why is it So Important?
It is widely 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
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 few years to ensure that the proposed SMPTE 2110 standard ecosystem continues to meet the needs of all stakeholders. The SMPTE ecosystem is now fully standardized and the industry is seeing rapid adoptions of ST 2110 across the board. The transition to Video over IP is well underway, and with it comes numerous benefits over traditional SDI based systems.
Forward Error Correction (FEC)
Live video transport in IP networks introduces the possibility for packet loss, due to the bit error rate of the infrastructure (typically 10E-12). This can have serious consequence given the quality required for broadcast transmission. FEC is a way to guarantee delivery of packets in imperfect transmission systems without requiring redundant data streams, enabling immediate recovery of lost packets on the fly.
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
Customers want their IP Gateways to interoperate seamlessly. Endpoint Validation is the only way to guarantee this. ST 2110 accomplishes this through industry interops, sponsored by the JT-NM.
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.
