Why DVB Adopted AV1 for Digital TV Broadcasting

The Digital Video Broadcasting (DVB) Project officially approved the AV1 video codec to expand its core specification suite, addressing the urgent demand for next-generation compression efficiency and flexible distribution. This article details why DVB embraced AV1, examining its superior bandwidth savings, its royalty-free licensing framework, its role in bridging traditional broadcast with broadband streaming via DVB-I, and the strategic importance of aligning global broadcast standards with modern consumer hardware ecosystems.

High-Efficiency Compression for Next-Generation Video

AV1, developed by the Alliance for Open Media (AOMedia), provides significantly higher compression efficiency than older codecs like AVC (H.264) and HEVC (H.265). In testing, AV1 routinely demonstrates bandwidth savings of 30% or more compared to HEVC at equivalent visual quality levels.

For broadcasters, spectrum and network capacity represent finite, expensive resources. AV1's high-performance algorithms allow network operators to deliver high-fidelity 4K Ultra HD, High Dynamic Range (HDR), and High Frame Rate (HFR) content using substantially less bandwidth. This efficiency is critical for maintaining video quality across constrained terrestrial airwaves and high-traffic broadband connections.

Royalty-Free Licensing and Economic Predictability

A primary driver behind the adoption of AV1 is its open-source, royalty-free model. Previous standards, particularly HEVC, suffered from fragmented patent pools, complex licensing terms, and unpredictable royalty fees that slowed adoption across both software platforms and low-cost consumer hardware.

Because AV1 is developed by a broad consortium of tech giants—including Google, Netflix, Amazon, Microsoft, and major chipmakers—it avoids the bureaucratic and financial friction of traditional patent pools. Adopting an open codec allows broadcasters, equipment manufacturers, and streaming providers to develop and deploy AV1-compliant workflows without the threat of unforeseen licensing liabilities.

Bridging Broadcast and Broadband with DVB-I and DVB-DASH

Modern digital television is rapidly shifting from purely dedicated RF transmission to hybrid delivery that combines traditional linear broadcast with broadband internet protocol (IP) networks. The DVB Project developed DVB-I (internet-delivered linear TV) and DVB-DASH (adaptive bitrate streaming) specifically to unify these domains.

AV1 has already achieved massive adoption across web streaming platforms, making it natively compatible with modern internet video infrastructures. By adding AV1 to the DVB toolbox for both broadcast and broadband profiles, DVB enables television networks to use a single, unified encoding pipeline for both traditional transmission and direct-to-consumer internet streaming, drastically simplifying media workflows.

Strong Hardware Ecosystem Support

Codecs succeed only when consumer playback hardware supports them at scale. Silicon manufacturers including MediaTek, Realtek, Broadcom, Intel, and AMD have integrated native, hardware-accelerated AV1 decoding into modern system-on-chips (SoCs).

Because smart TVs, set-top boxes, and mobile devices now ship with built-in silicon support for AV1, DVB recognized that the consumer ecosystem was primed. Broadcasters can mandate AV1 compatibility in national or regional digital TV receiver profiles knowing that compliant consumer hardware is readily available and affordable.

Future-Proofing Global Broadcast Standards

DVB's endorsement of AV1 ensures that broadcast standards remain technologically competitive with proprietary over-the-top (OTT) streaming platforms. By standardizing AV1 alongside established codecs like HEVC and emerging options like VVC (Versatile Video Coding), DVB provides broadcasters with the architectural flexibility required to serve multiscreen audiences reliably over the next decade.
