Voices of VideoQuality, Cost, Latency: The Hidden Battles in Video DeliveryStarting with signal reception at massive satellite dishes, Martin Azpiroz, director at Bold MSS walks us through the complete delivery chain, from transcoding and packaging to content protection and playback. We explore Bold MS's fascinating technical evolution from CPU to GPU to their current ASIC-based encoding approach. This shift hasn't just improved video quality; it has also dramatically reduced hardware failures, server footprint, and power consumption. As Martin explains, some providers have discovered that server energy costs can reach 30% of the hardware's replacement value annually, making these efficiency gains financially significant.• Bold MS offers a c...2025-07-2439 min
Voices of Video600 Channels, 1 Server - Reimagining Video Processing for SustainabilityHardware acceleration is changing the economics of video delivery, and Scalstrm is at the forefront of this revolution. After showcasing their just-in-time transcoding solution at NAB, Dominic returns to Voices of Video to share how they've partnered with NETINT to create a groundbreaking platform that's already winning customer deployments.• Scalstrm built their transcoding solution from scratch without relying on open-source components• Their migration from software to hardware acceleration took only 3-4 months• Performance testing showed "huge" advantages using VPU cards over CPU-based transcoding• The solution supports all major codecs including H.264, HEVC, and has plans fo...2025-07-1732 min
Voices of VideoFrom VHS Tapes to Huddle: The Evolution of Sports Video AnalysisCasey Bateman, Principal Engineer at Huddle, reveals how their video platform revolutionized sports analysis by replacing the old system of coaches exchanging physical tapes with instant digital access. Founded in 2006 at the University of Nebraska, Huddle now serves 97% of US high school football programs and has expanded globally to 40+ sports.• Huddle's first client was Nebraska football in 2007, followed by the NY Jets when their coach moved teams• Explosive growth began when targeting high schools - from 12 schools in 2008 to 1,300 by 2010• Currently powers video analysis for 230,000 different organizations globally across 40 different sports• Platform optimizes for clear je...2025-07-1054 min
Voices of VideoCores Galore: Video Processing Without the Computational GymnasticsARM architecture is revolutionizing video processing with power-efficient processors that deliver predictable performance without the computational gymnastics required by traditional x86 systems.• Ampere builds ARM-based processors with massive core counts (up to 192 cores) focused on sustainable computing• Traditional x86 architecture struggles with video workloads due to multi-threading causing unpredictable performance• Single-threaded cores in ARM processors provide predictable execution crucial for video processing• ARM processors consuming just 1 watt per core enable 320 simultaneous 1080p30 live transcodes in a single 1RU server• When paired with VPUs for encoding, ARM cores can handle complex tasks like de-interlacing, MPEG-2 dec...2025-07-031h 01
Voices of VideoThe Onion Layers of Video: A Deep Dive into WebRTCWebRTC pioneer Tsahi Levent-Levi shares his extensive knowledge on this real-time communication protocol, explaining its inner workings, challenges, and proper implementation approaches.• WebRTC consists of both a protocol stack (standard specification) and Google's implementation (libwebrtc) used in all major browsers• The protocol is designed specifically for real-time communication with sub-second latency requirements• When building with WebRTC, consider using third-party solutions rather than building from scratch• Quality challenges arise from network unpredictability, requiring compromises to maintain real-time communication• Simulcast (creating multiple streams at different bitrates) remains more widely adopted than SVC due to hardware compatibil...2025-06-2657 min
Voices of VideoWho Owns Your Digital Brain?Reza Rasool, CEO of nonprofit AI lab KWAI, shares his vision for democratizing artificial intelligence through personal AI systems that prioritize user privacy and local computing.• KWAI aims to create personal AI assistants that run locally on users' devices rather than in the cloud• Current cloud-based AI services create privacy concerns as they require uploading personal data to remote servers• Retrieval Augmented Generation (RAG) technology separates language models from knowledge bases for more efficient local processing• The streaming media industry's evolution provides valuable lessons for developing standardized, componen...2025-06-1951 min
