Video: JPEG XS in Action for IP Production

JPEG XS is a new intra-frame compression standard delivering JPEG 2000 quality with 1000x lower latency – microseconds instead of milliseconds. This codec provides relatively low bandwidth (visually lossless compression at ratio of 10:1) with very-low and fixed latency, which makes it ideal for remote production of live events.

In this video Andy Rayner from Nevion shows how JPEG XS fits in all-IP broadcast technology with SMPTE ST 2110-22 standard. Then he presents the world’s first full JPEG-XS deployment for live IP production created for a large sports broadcaster. It was designed for pan-European WAN operation and based on ST 2110 standard with ST 2022-7 protection.

Andy discusses challenges of IP to IP processing (ST 2110-20 to ST 2110-22 conversion) and shows how to keep video and audio in sync through the whole processing chain.

This presentation proves that JPEG-XS is working, low latency distributed production is possible and the value of the ST2110-22 addition to the 2110 suite.

Video: M6 France – Master Control and Playout IP Migration

French broadcast company M6 Group has recently moved to an all-IP workflow, employing the SMPTE ST 2110 suite of standards for professional media delivery over IP networks. The two main playout channels and MCR have been already upgraded and the next few channels will be transitioned to the new core soon.

The M6 system comprises equipment from five different vendors (Evertz, Tektronix, Harmonic, Ross and TSL), all managed and controlled using the AMWA NMOS IS-04 and IS-05 specifications. Such interoperability is an inherent feature of SMPTE ST 2110 suite of standards allowing customers to focus on the operational workflows and flexibility that IP brings them. Centralised management and configuration of the system is provided through web interfaces which also allows for easy and automated addition of a new equipment.

Thanks to Software Defined Orchestration and intuitive touch screen interfaces information such as source paths, link bandwidth / status, and device details can be quickly accessed via a web GUI. As the system is based on IP network, it is possible to come in and out of fabric numerous times without the same costs implications that you would have in the SDI world. Every point of the signal chain can be easily visualised which enables broadcast engineers to maintain and configure the system with ease.

Video: IP Test and Measurement for ST 2110 Systems

As the transition to IP-based transport for video, audio, and data continues. The early adopters have already demonstrated the operational and commercial benefits of COTS IP infrastructure and SMPTE ST 2110 video-over-IP standard suite becomes mature now. However, configuration and troubleshooting of IP systems requires a completely new skillset. Broadcast engineers need to gain an understanding of the technology and the new techniques required to monitor these signals.

In this video Kevin Salvidge from Leader shows what test and measurement tools you need to ensure you continue to deliver the same quality of service that can be achieved with SDI systems.

Kevin looks at the main differences between traditional and IP systems which stem as much from a move from synchronous to asynchronous infrastructure as the way you measure how well the system is working.

The following topics are covered:

  • Frame Check Sequence (FCS), Cyclic Redundancy Check (CRC)
  • Packet jitter measurement (avoiding buffer underrun)
  • Monitoring ST 2022-7 path delay between the two feeds
  • PTP synchronization (offset and delay graphs, synchronisation accuracy)
  • Checking that video, audio and ANC signals are synchronised with PTP and RTP timing measurement
  • Packet Header Information looking at MAC, IP, UDP, RTP as well as the payload
  • SFP Information (10/25 Gb, multimode / single mode etc.)
  • IP Event Log e.g. Grand Master change
  • Hybrid IP and SDI Video and Audio Test and Measurement

Video: What’s New in NMOS? – A Tutorial on the Latest in Video over IP Control and Security

The Networked Media Open Specifications (NMOS) have been developed to provide a control and management layer along side the SMPTE ST 2110 transport layer. The idea behind NMOS was to deliver an open specification to provide the software layers that abstract a lot of complexities of ST 2110 and make it easy to interface with any control system.

The NMOS family of specifications began with projects for Discovery & Registration, Device Connection Management and Network Control, but has grown to include many other important subjects such as Event & Tally, Audio Channel Mapping and Interoperable Security.

In this video, Jed Deame discusses the latest advancements including IS-08, IS-09, BCP-002, BCP-003 and IS-10. These additions allows NMOS to surpass the level of control provided in SDI while also adding a layer of security.

The following Interface Specifications and Best Current Practices are presented:

  • IS-04 (Registration and Discovery) – new features: support for GPI over Ethernet (IS-07) and authorisation signalling for security layers BCP-003-02
  • IS-05 (Connection Management) – new features: MQ Telemetry Transport and WebSocket Transport, support for supplementary externally defined parameters
  • IS-08 (Audio Mapping) – audio routing / shuffling facility
  • IS-09 (System Resources) – System ID, server priority, security with HTTPS support, advertisement of system resources such as RDS (Registration and Discovery Server)
  • BCP-002 (Grouping) – uses tag resources in IS-04 in order to achieve a natural groups of senders and receivers (e.g. to tie audio, video and metadata)
  • BCP-003-01 (Security) – uses Transport Layer Security (TLS) in order to encrypt communications between API servers and their clients
  • BCP-003-02 (Security) – covers client authorization for the NMOS APIs
  • IS-10 (Authorisation API) – accompanies the BCP-003-02 specification to restrict what users are authorized to change in an NMOS system (core technologies: PKI, HTTPS, REST, JSON, Oauth 2.0 and JWT)

The presentation finishes with the customer case study – secure KVM all over an IP network.
