Bridging the SDI/IP Gap with Telestream

By Ian Valentine, VP of Product Management...

Within broadcast operations of all sizes and scales, effective test & measurement is not an option - it is an essential pre-requisite of efficient workflows throughout a facility. Today, the big challenge facing tech vendors is to create test & measurement systems that reflect the latest trends such as the move towards IP, 4K, 8K and HDR content.  

One company that is investing massively in this area is Telestream. Recently, the company announced the latest software upgrade for its PRISM Waveform Monitor. Built for post production, live production and engineering, the latest release supports enhanced test tools for UHD and 4K/8K with RGB 4:4:4 12-bit HDR/WCG and False color tools as well as support for the latest immersive audio surround formats.  

The release streamlines post production mastering and compliance workflows for UHD, HDR, by providing objective measurements through easy to use and configure tools for both exposure and color management. Experienced post production staff can often subjectively gauge video quality on a regular monitor for HD/SD content, but this is very difficult to do with UHD/HDR standards. Editors and colorists need to know how much of the image is in the HDR zone and where their lightest highlights are, and their darkest shadows are. They also need tools to tell them that the color in the mastered content is correct and error free, something that gets more difficult across multiple color spaces. If not done correctly, media services providers like Netflix, Amazon, and Hulu will reject non-compliant content causing post production delays and cost over-runs. 

PRISM provides an arsenal of tools to help production professionals get it right. From the use of configurable false color displays for both luminance and gamut errors, stop displays that measure exposure directly in light levels to the traditional color and exposure tools such as vector and waveform displays. PRISM provides what’s required to ensure compliance with UHD content requirements such as Netflix standards and enables post production teams to guarantee their productions pop off the screen. 

In both live and post production there is constant time and commercial pressure to deliver high quality content, and so anything that improves operational efficiency has great value. Following in depth customer research, the latest release of software introduces a new user interface specifically designed to simplify the selection, use and configuration of the broad range of applications available on PRISM. The new UI provides a hot bar which can be customized to include the key applications needed for the application the PRISM is being used for, be it Live or Post Production, Engineering or Technical QC.  

Further flexibility is provided through the use of up to 36 different presets which can be used to instantly reconfigure the PRISM and the hot bar layout for different applications. Those Presets can be exported and remotely downloaded on to multiple PRISMs to ensure the whole team is working in a consistent fashion and with the instrument is configured for their particular workflows. Not only can the presets be exported and installed remotely, but PRISM itself can be accessed and controlled remotely through a web UI. This is important in a world that has been changed by a pandemic that requires teams to work and collaborate from a distance.  

Other features in this release include the use of four active trace tiles, capture and decoding of SCTE 104 messages and the ability to select and down mix stereo and 5.1 surround audio channels.

This provides the combination of large-scale automated monitoring & detailed analysis operations teams need. 

Instruments like PRISM tend to be analyzers. They will look at a few selected signals on which users can then perform a series of deep analytic measurements. They are ideally suited to the job performed by individuals working in QC, Live Production, Post Production and Engineering. However, for those in Operations who are responsible for ensuring that all the signals being used in a facility or being transmitted are correct they need tools that will monitor signals on a large scale, but that perform less in depth measurements than an analyzer. This is about visibility and warnings rather than deep analysis and diagnostics.  

As broadcast operations migrate from SDI to IP, there is a need for test & measurement systems that support this sea-change in operating environment. Telestream’s new Inspect 2110 probes monitor provides the large-scale monitoring required in an Operational environment.  

Inspect 2110 is designed to answer four critical questions for operators. Is the content that is on the network  supposed to be on the network, and if it is, is it correct or what is expected to be there? Are the ST2022-7 redundant streams robust and reliable? Is the PTP synchronization system setup correctly and stable? Are there any issues in the IP network, such as an increasing number of lost packets or timing delays, that will cause problems? 

There are numerous network statistics that can be harvested from infrastructure equipment such as switches. Inspect 2110 looks at that information. 

However, what sets Inspect 2110 apart is its ability to look at the actual content being carried and to check whether it is correct. Totally configurable for the environment in which it will be used, the 2110 probe provides a dashboard, thumbnails, hierarchical warning and error alarming with comprehensive logs, all designed to help operators to rapidly respond to systems issues in an informed way. 

The probes can be positioned to provide visibility across the whole workflow from acquisition, through contribution and in the facility. Each probe can monitor up to 100Gbps of ST 2110 video, audio and data.  

Inspect 2110 uses the system SDP files to ensure that the content is correct. The probe compares the primary and redundant streams to ensure they are the same, that neither service is degraded and that the timing is correct to enable secure switch over when required. 

Inspect also monitors the system PTP and will report changes of events on the system, for example a change in the Grandmaster.  

Should deep analysis or diagnostics be required, Inspect 2110 provides automated direct click connectivity to PRISM, providing an industry leading combination of ST 2110 monitoring and deep analysis. 

Throughout its development, Telestream has future-proofed Inspect 2110’s design at every stage. It features an API-first container-based microservice architecture for automation, which is ready for cloud-centric architectures. 

With Inspect 2110 and PRISM operating in combination Telestream has developed the first ST 2110 Monitoring & Waveform Monitor single vendor solution.
