B2B Content Distribution over CDN for OTT and Broadcast Services - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Immersive Audio, Satellite and OTT DeliveryThe 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.

Beyond the Cloud: Native Broadcasting with ATSC 3.0 - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Embracing the Cloud: Transforming Broadcast Operations with ATSC 3.0 and Broadband TechnologiesThe broadcast industry is undergoing a major shift as broadcasters increasingly integrate cloud-based solutions to enhance the efficiency, reliability, and scalability of their operations. The advent of ATSC 3.0—a next-generation broadcast standard—enables the entire broadcast operations chain to become ‘cloud-native,’ opening unprecedented opportunities for flexible and resilient deployment strategies. This paper proposes a unified approach to cloud-to-terrestrial broadcasting, examining how ATSC 3.0’s capabilities can support such a fully integrated broadcast infrastructure. By analyzing current and potential implementations, we highlight the transformative potential of cloud-based broadcasting for optimizing playout, signal distribution, and emission. The goal is to provide a blueprint for broadcasters navigating the shift to a future-ready, cloud-centric operational paradigm.

Bit-Rate Evaluation of Compressed HDR Using SL-HDR1 - $15
Date: April 26, 2020Topics: 2020 BEITC Proceedings, Managing HDR and SDR ContentFrom a signal standpoint, what differentiates High Dynamic Range (HDR) content from Standard Dynamic Range (SDR) content is the mapping of the pixel samples to actual colors and light intensity. Video compression encoders and decoders (of any type) are agnostic to that ? the encoder will take a signal, compress it, and at the other side, the decoder will re-create something that is ?about the same? as the signal fed to the encoder. Existing encoders may have been optimized to provide good results with SDR, but HDR will still flow through, albeit possibly requiring higher bit rates for good reproduction.
Some of the HDR standards include dynamic metadata to help a display device render the content based on its capabilities. Some standards transmit a native HDR signal with metadata that allows the creation of anything from the original HDR all the way down to SDR. SL-HDR1, on the other hand, does the opposite: An SDR signal is transmitted, with metadata to inverse tone map to HDR. This metadata adds overhead to the video elementary stream.
This paper focuses on the required bit rates to produce a final HDR signal over a compressed link. We compare encoding SMPTE-2084 PQ HDR signals directly versus using SL-HDR1 to generate an SDR signal plus dynamic metadata. The comparison is done objectively by comparing the PSNR of the decoded signal. The SMPTE-2084 HDR signal is used as a reference at a fixed bit rate, and the bit rate of the SL-HDR1 encoded signal is varied until it matches the PSNR, over a range of source material. The evaluation is done for both AVC (H.264) and HEVC (H.265). This is similar to the work by Touze and Kerkhof published in 2017, but using commercial equipment.

Boosting the efficiency of OTT delivery with state-of-the-art streaming optimizations - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Digital Online OperationsAn increase in streaming capacity has driven OTT service providers to look for ways to reduce the cost of video streaming without decreasing the overall quality of experience (QoE). Through the latest streaming optimizations, video service providers can achieve significant bandwidth savings, while retaining exceptional video quality. This paper examines the current state of the art in streaming innovations by looking first at the popularity of deployed codecs (AVC, HEVC, AV1), then seeing how Content Aware Encoding (CAE) can be used to improve their respective performances. It then looks beyond CAE at additional AI-based techniques such as dynamic parameter selection, dynamic frame encoding, dynamic resolution encoding that can further improve the compression efficiency. It then looks at additional techniques impacting the QoE that can be deployed to further reduce the bandwidth such as zero rating deployed in the mobile space, resolution reduction on PC, or 1080p for sports on TV. Last, it looks at encoding orchestration where content popularity will impact the processing power allocated to encoding to reduce the bitrate adaptively based on content popularity. The paper develops a model that shows starting from a Constant Bit Rate (CBR) HD AVC solution, and depending on the tools used, with or without QoE reduction, what bandwidth reduction can be achieved.

BPS ATSC 3.0 Broadcast Emission Time Stabilization System Proof-Of-Concept - $15
Date: April 14, 2023Topics: 2023 BEITC Proceedings, National Security Applications of ATSC 3.0The ATSC 3.0 NextGen TV standard defines a precise time stamp of the emission time of each broadcast frame. The time stamp, along with the transmitting antenna location, can be used to determine the distance of the receiver from the transmitter. If at least three such ATSC 3.0 transmissions are available in an area, these broadcasts can be used as a precise positioning system, called a Broadcast Positioning System (BPS) [1], which can be used as a backup system for the Global Positioning System (GPS).
However, providing a precise time stamp is technically challenging due to various delays and variability in the broadcast transmission studio processing chain. This paper describes a proof-of-concept system, developed by multiple partner companies under the direction of NAB Pilot, that provides a closed loop time stabilization system. The paper explores the techniques used to measure the broadcast signal’s emission time and to compensate for the processing chain timing variability stabilizing the emission time stamp. The paper also describes the lessons learned and the barriers to further improve the timing accuracy of the BPS system.
