TSENet Video Super Resolution for Broadcast Television - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Production Advancements: Avatars and Immersive ContentThe emergence of Video Super Resolution (VSR) has advanced the media industry. It holds great potential for enhancing broadcast and streaming, improving visual quality, and boosting user engagement. While there are benefits, applying VSR technology to broadcast presents challenges, as it requires a high-quality solution that maintains consistent quality across diverse broadcast standards, handles live content with minimal latency, and ensures compatibility with existing broadcast infrastructure. This demands sophisticated AI models, often needing high-performance GPUs, which can increase costs. In this paper, we introduce a method to upscale low-resolution, compressed video frames based on an enhanced version of Equivalent Transformation and Dual Stream Network (ETDS)[1], called a Temporally Stabilized ETDS Network (TSENet) that performs equivalent or better compared to more compute extensive solutions. This paper examines various VSR models, emphasizing the key performance indicators identified by the AIM2024 Challenge for Efficient VSR[2]. The focus is on deploying these models in workflows, considering visual quality through both subjective and objective analyses, compression artifact reduction, and real-time processing capabilities.

Two-Pass Encoding for Live Video Streaming - $15
Date: March 21, 2025Topics: 2025 BEITC Proceedings, Enhancing Video Streaming Quality and Efficiency2025 NAB BEIT Conference Proceedings Best Student Paper Award Winner
Live streaming has become increasingly important in our daily lives due to the growing demand for real-time content consumption. Traditional live video streaming typically relies on single-pass encoding due to its low latency. However, it lacks video content analysis, often resulting in inefficient compression and quality fluctuations during playback. Constant Rate Factor (CRF) encoding, a type of single-pass method, offers more consistent quality but suffers from unpredictable output bitrate, complicating bandwidth management. In contrast, multi-pass encoding improves compression efficiency through multiple passes. However, its added latency makes it unsuitable for live streaming. In this paper, we propose OTPS, an online two-pass encoding scheme that overcomes these limitations by employing fast feature extraction on a downscaled video representation and a gradient-boosting regression model to predict the optimal CRF for encoding. This approach provides consistent quality and efficient encoding while avoiding the latency introduced by traditional multi-pass techniques. Experimental results show that OTPS offers 3.7% higher compression efficiency than single-pass encoding and achieves up to 28.1% faster encoding than multi-pass modes. Compared to single-pass encoding, encoded videos using OTPS exhibit 5% less deviation from the target bitrate while delivering notably more consistent quality.

Ultra-Low Latency OTT Delivery: The Killer Technology for Betting, Social Networking and Metaverse - $15
Date: April 14, 2023Topics: 2023 BEITC Proceedings, OTT / Connected TVUltra-low latency over-the-top (OTT) video streaming is becoming increasingly important in gaming, metaverse, and gambling applications, enabling social interaction and monetization in live events such as sports and concerts. Moreover, all those applications are conceptually converging. These applications require real-time, interactive experiences that are highly responsive and immersive, and ultra-low latency OTT streaming is essential for delivering this type of experience. Tremendous innovation resources have been invested to build robust OTT delivery systems with ultra-low latency capabilities. Necessary optimizations affect most steps from encoding to packaging and even last mile delivery. In this paper, we explain a setup that leverages the ultra-low latency technology using the Live Media Ingest Protocol and Just-In-Time packaging. We also explore how such setup can be used to enable amazing technologies that have direct impact on the performance of the Content Delivery Network (CDN) and the users’ quality of experience (QOE) to achieve the seamless and immersive experience they require.

Understanding Digital FM Asymmetric Operation - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Radio TopicsThe FCC is considering a rule change that will make it easier for FM-band HD Radio™ broadcasters to operate with asymmetric digital sidebands. Doing so gives broadcasters the opportunity to increase digital power on one sideband only, providing improved coverage while mitigating interference to adjacent-channel stations. This paper includes background information on asymmetric sideband operation, and its application to broadcast stations. A shift to asymmetric power levels will require broadcast engineers to change how they describe and employ digital sideband levels on a station.

Unified System Design - $15
Date: April 14, 2023Topics: 2023 BEITC Proceedings, Broadcast Facility DesignOver the past two decades, the media industry has needed to adapt to new IP delivery methods that enable high-quality content to be delivered over private networks and the internet. More recently the transition to IP has progressed further upstream in the media supply chain with the wide availability of network hardware that can support uncompressed video over IP in the form of SMPTE ST 2110. However, in this transition to a future where all media flows are carried over IP networks, the methods used for design and documentation have not been able to keep up. New approaches and tools are required.
