The Society of Television Engineers

Welcome to the Society of Television Engineers Web Site.  Established in 1940, STE is an organization unique to Los Angeles, Hollywood and the surrounding areas.  Its members include key individuals involved in television broadcast engineering and the manufacture of television broadcast equipment.  The purpose of the STE is to provide a common ground for people in the video, broadcasting and related technologies to meet up, trade experiences and learn about new products and methods.  If you are working in video production, broadcast, post production, or systems design/integration, you will find others with similar backgrounds at the STE.

---------------------------------------------------------------------

Meetings

STE dinner meetings are usually held on the third Thursday of each month except for July and August. Meeting activities include a social cocktail hour, dinner, a table-by-table industry event reports and introduction of guests. This is followed by a formal program that covers new or interesting broadcast, production and post production systems, standards, products, or techniques.  Meetings are open to anyone interested in the field.

The Transition from SDI to ST 2110 IP and ST 2059 PTP
Best Practices and Lessons Learned

Increasing scale, collaboration and diversity of workflows are driving the media and entertainment industry toward a new model for media storage. Content growth, ever increasing file sizes and resolutions have placed tremendous pressure on storage systems. The modern media organization demands productive collaboration, meaning timely multi-site access to assets is crucial to success. Furthermore, modern workflows rely on efficient analysis and adaptive workflows, with organizations often requiring simultaneous workflows within a single infrastructure, exceeding the functionality of the traditional file systems. 
The modern media storage paradigm focuses on the usage of assets, combining a file-based “project tier” and an object-based “perpetual tier” in a new two-tier paradigm. The project tier leverages the file system’s high bandwidth, high-performance random I/O and ability to write to any location within a file to manage dynamically-changing assets and workspaces. The perpetual tier relies on object storage’s use of HTTP to maintain a simple, RESTful interface that can operate at scale, send an object in multiple parts and retrieve a range or part of an object. The technology enables encryption and access controls (Uniform Resource Identifier or URI) for safe sharing of creative assets across the public internet and pre-staging of objects at remote locations. The semi-static nature of objects further allows them to be cached in global content delivery networks for cloud-based distribution of completed files and their respective descriptive manifest. Content moves seamlessly between the two tiers as assets are manipulated, analyzed, shared and protected. 
Join us for a deeper look into the nuances of the two-tier system and what this redefinition means to the industry at large. We will follow the journey of creative assets through this two-tier model and provide new insights on how media organizations stand to benefit from this modern framework.

Topics of Discussions:
This presentation will be a tutorial on what you need to know to understand the challenges we face in making the transition from SDI to an IP based transport for video, audio and data. Karl will share what he has learned by being involved in several ST 2110 and ST 2059 deployments with a focus on what questions early adopters wish they had asked. New troubleshooting methodologies are required to visualize variable delay across the network and how critical multilayer trend measurements can be made on the stream to improve QoS and QoE. 



Happy New Year 2020
