The Broadcast Knowledge exists to help individuals up-skill whatever your starting point. Videos like this are far too rare giving an introduction to a large number of topics. For those starting out or who need to revise a topic, this really hits the mark particularly as there are many new topics.
John Mailhot takes the lead on SMPTE 2110 explaining that it’s built on separate media (essence) flows. He covers how synchronisation is maintained and also gives an overview of the many parts of the SMPTE ST 2110 suite. He talks in more detail about the audio and metadata parts of the standard suite.
Eric Gsell discusses digital archiving and the considerations which come with deciding what formats to use. He explains colour space, the CIE model and the colour spaces we use such as 709, 2100 and P3 before turning to file formats. With the advent of HDR video and displays which can show bright video, Eric takes some time to explain why this could represent a problem for visual health as we don’t fully understand how the displays and the eye interact with this type of material. He finishes off by explaining the different ways of measuring the light output of displays and their standardisation.
Yvonne Thomas talks about the cloud starting by explaining the different between platform as a service (PaaS), infrastructure as a service (IaaS) and similar cloud terms. As cloud migrations are forecast to grow significantly, Yvonne looks at the drivers behind this and the benefits that it can bring when used in the right way. Using the cloud, Yvonne shows, can be an opportunity for improving workflows and adding more feedback and iterative refinement into your products and infrastructure.
Looking at video deployments in the cloud, Yvonne introduces video codecs AV1 and VVC both, in their own way, successors to HEVC/h.265 as well as the two transport protocols SRT and RIST which exist to reliably send video with low latency over lossy networks such as the internet. To learn more about these protocols, check out this popular talk on RIST by Merrick Ackermans and this SRT Overview.
Rounding off the primer is Linda Gedemer from Source Sound VR who introduces immersive audio, measuring sound output (SPL) from speakers and looking at the interesting problem of forward speakers in cinemas. The have long been behind the screen which has meant the screens have to be perforated to let the sound through which interferes with the sound itself. Now that cinema screens are changing to be solid screens, not completely dissimilar to large outdoor video displays, the speakers are having to move but now with them out of the line of sight, how can we keep the sound in the right place for the audience?
This video is a great summary of many of the key challenges in the industry and works well for beginners and those who just need to keep up.
Media production is at an all-time high—with no signs of slowing down. By 2020, storage capacity requirements are predicted to increase by over 300%.
This explosive growth has facilities facing mounting issues sure to impact their media assets across every storage tier—especially when a significant percentage of their data is currently living on aging LTO-5/6 tapes.
Join on Thursday, November 29th to learn how to prepare your organization for the future by leveraging the power of AI combined with the latest LTO and disk-based storage technology.
In this webinar, you’ll learn
• Smart migration strategies for moving from LTO-5/6 to LTO-7/8
• How to use AI to eliminate countless hours of metadata logging and create a searchable database of your online, nearline, and archived media
• Ways to improve accessibility and organization across your entire storage infrastructure
BBC Northern Ireland produces a complete schedule of news and current affairs programming that it distributes over two television channels, two radio stations, and multiple online platforms.
BBC NI also delivers content from other BBC production centers to Northern Ireland audiences. In addition, its facilities also serve as a central digital archive for the Rewind Projects, hosting thousands of hours of existing content from all of the BBC’s different national sites.
To meet their challenge of storing, protecting, and making the content available for reuse, they turned to a workflow management solution from Cinegy built on the Quantum StorNext storage platform.
Attend this webinar and learn more about key elements of the BBC NI solution:
• Unified asset management environment spans multiple, discrete storage tiers for storing video and audio essences together with metadata
• Teams of users and applications in all areas have fast, simultaneous access to all media content on disk and tape
• Automated movement of data between disk and tape tiers for backup and archive
• High-speed, multi-stream transcoding delivers content quickly for accelerated production because data is visible on any computer
• Dual-redundant systems supports around-the-clock operations and provides back-end storage support to ensure DR protection
• A scalable solution that can grow as storage demands increase in the future
From AWS re:Invent 2017, Michael Koetter from Turner and Bhavik Vyas from AWS explain that Turner is creating a copy of CNN’s 37-year news video library in AWS to take advantage of the cost and architectural benefits of cloud storage.
This project has unique requirements around retrieval times, and Turner partnered with AWS to drive specific capabilities such as those Amazon Glacier expedited and bulk retrieval options. These cloud-based archives can enable Turner to use other cloud-based value-add services, such as AI/ML/search, and media supply chains efficiently. Turner’s global content exploitation strategies call for extensive versioning of content assets required for distribution to different platforms, products, and regions.
Today, this involves complex workflows to derive multiple downstream versions. Adopting the SMPTE Interoperable Mastering Format (IMF) and cloud-based object storage, Turner will dramatically simplify these workflows by enabling cloud-based automation and elastic scalability. Hear Turner’s strategy, implementation around these media workloads, and lessons learned.
