B2B Content Distribution over CDN for OTT and Broadcast Services  - $15

The evolution of content delivery technologies for OTT and broadcast services has transformed how media is distributed, shifting from satellite-based models to CDN-based frameworks. This paper introduces “B2B Content Distribution over CDN,” a modern approach leveraging CDNs and industry-standard DRM technologies—Widevine, PlayReady, and FairPlay. This method ensures cost-efficient, scalable, and secure content delivery across diverse platforms. Core components, including the Common Encryption Scheme (CENC) and the Content Protection Information Exchange (CPIX) protocol, streamline secure key management and distributor access. Advanced features like channel-based access control, real-time content revocation, and blackout enforcement enhance content management while complying with regulatory requirements [1] [2]. By reducing reliance on traditional satellite systems, B2B Content Distribution offers broadcasters and Over-the-Top (OTT) providers with a robust alternative for modernized content delivery.

Optimizing Satellite/Internet Hybrid Content Delivery Using Program Selection - $15

The Reliable Internet Stream Transport (RIST) Activity Group in the Video Services Forum has been working on a common industry specification for methods to augment satellite delivery using the Internet. The satellite is used for the “heavy lifting”, and the Internet is used to “fill in the gaps”.

Such a system can be further augmented by allowing the receivers to select which programs they require. If this can be achieved, further internet bandwidth optimization is possible, since the headend does not need to “fill in the gaps” for the programs that are not required for that receiver. This method can be designed in a manner that is general enough to apply to other internet transport scenarios in addition to hybrid satellite delivery. The RIST Activity Group has created a backward-compatible extension to RIST Main [1] and Advanced [2] Profiles to allow a receiver to communicate to the sender its content requirements. Once the sender is made aware of these requirements, it can optimize the bandwidth without losing timing compliance by using the NULL Packet Deletion functionality defined in RIST Main Profile. This extension has been published by the Video Services Forum as TR-06-4 Part 6 [3]. This paper is a detailed overview of the technical details of TR-06-4 Part 6, with some application examples derived from existing broadcast feeds. It also includes practical data on bandwidth savings from actual off-air ATSC-1 content.

Why do you need proactive video delivery network observability?  - $15

The rapid adaptation of IP workflows in production, contribution, cloud, and distribution is always challenging. Organizations spend millions of dollars training the workforce, deploying monitoring solutions and troubleshooting “network issues,” which takes an enormous portion of their tasks. Time and effort are wasted on old techniques that were suitable for standard file delivery versus today’s high throughput and low latency demands of live production.

In this paper we would like to draw your attention to a different way of thinking, observing and gaining in-depth understanding of the lifeline of the broadcast industry: the network. The traditional reactive way of monitoring events and alarms must evolve to use proactive observability. Unlike standard observability that just collects data from elements and passive probes, proactive observability involves injecting small amounts of traffic into the network to discover the network routes and to support the continuous measurement of the performance of the traffic to gain valuable insights into the experience of the traffic.
