Satellite/Internet Hybrid Content Delivery (Ku-Band Without Rain Fade!) - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Content Creation and Delivery TechnologySatellite distribution is the ideal way to send the same content to many locations that are geographically distributed. However, the traditional C-band distribution is now impacted by the new 5G cellular network, which operates mostly in the 3.3 to 3.6 GHz band (which partially overlaps with the Space-to-Earth spectrum). Ku-band is not impacted by 5G, but unfortunately it is subject to rain fade. One possible approach to solving this content delivery problem is to augment satellite delivery using the Internet. The basic idea is to use the satellite for the “heavy lifting” (transmitting as much data as viable), with the Internet to “fill in the gaps”. In other words, any data that is corrupted or lost in transit is retransmitted over the Internet, and only to the locations that need it. This way, if a region is experiencing any sort of fade or interference, only the receivers in that region need to use the Internet. Any solution to this problem needs to be designed in such a way that it can co-exist with current receivers. This means that the signal transmitted to the satellite either cannot change, or any changes to it must be backward-compatible with existing receivers. Broadcasters utilizing this solution can then gradually deploy the solution as needed, with high-priority sites being upgraded first. The Reliable Internet Stream Transport (RIST) Activity Group in the Video Services Forum (VSF) has been working on this problem, to create a common industry Specification for addressing it. Having such a Specification will allow interoperability between solutions, and not lock broadcasters into a single vendor. This Specification is expected to be published as VSF TR-06-4 Part 6, sometime in 2024. This paper is a technical overview and discussion of the techniques and algorithms which are being considered for inclusion in the VSF Satellite/Hybrid Specification.

Securing Hybrid Media and Entertainment Workflows Practical Strategies for Protecting Intellectual Property and Critical Assets - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Cybersecurity for BroadcastersThe media and entertainment industry has undergone a significant shift towards hybrid and cloud-based workflows. As organizations leverage a growing ecosystem of Software as a Service (SaaS) solutions and multi-vendor integrations, new security challenges have emerged. These hybrid environments, which often involve on-premises storage and processing coupled with cloud-based services and remote users, present potential compromise vectors for sensitive data and assets. This paper explores practical strategies to address security threats and safeguard intellectual property, pre-release assets, and other critical resources within hybrid media and entertainment workflows. It will examine the diverse threat vectors malicious actors can exploit, with a focus on vulnerabilities introduced by SaaS solutions and the integration of bespoke vendor offerings.

Security for Discovery and Connection Management of ST2110 Media Devices - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, Media over IP: Security and TimingWhile the networked media open specifications (NMOS) allow for easy adoption from the broadcast industry, they are fully documented and would easily allow man-in-the-middle attacks to retrieve vital device information, such as IP addresses for accessing control ports. Usage of those control ports by unauthorized personnel could lead to disruptions in the production chain.
AMWA BCP-003 can be used to encrypt all API traffic with TLS to initially prevent man-in-the-middle attacks. As there are many cipher suites to choose from, this paper describes why the current list of suites was chosen to cover both best security and compatibility with legacy broadcast equipment with minimal computing performance. The paper will then explain how a broadcast facility can practically deploy the needed Public Key Infrastructure and how devices that are installed after initial deployment can be added.
Furthermore, we will focus on AMWA IS-10 as a means of specifying authorization mechanisms to secure access to NMOS APIs such as IS-04, -05, or -08. We will also explain the current concept of an authorization server and how it can issue tokens for controllers and nodes. In this way, we can secure NMOS nodes against unwanted access for starting/stopping/configuring media endpoints. The choice of API for finding the server and retrieving tokens is closely linked to other NMOS APIs, in order to allow for fast adoption.
