Executive Summary
The rapid growth of 4K/8K video, streaming services, cloud gaming, and immersive media is driving demand for advanced video codecs with higher compression efficiency, lower bandwidth requirements, reduced latency, and improved processing efficiency. The video coding landscape is evolving from a single-standard ecosystem to a multi-codec environment. While H.264/AVC remains widely deployed due to its mature ecosystem, newer standards such as H.265/HEVC, AV1, EVC, and VVC/H.266 are gaining adoption by offering improved efficiency and scalability. Future developments beyond VVC, including AI-based compression and neural video coding, are expected to enable next-generation applications such as 8K streaming, immersive media, and intelligent video services.
1. Introduction
Video codecs are the foundational technologies enabling today’s digital media ecosystem, powering applications ranging from real-time video conferencing and social media platforms to ultra-high-definition streaming, cloud gaming, and immersive virtual and augmented reality experiences. A video codec functions by compressing raw, unprocessed video data into significantly smaller files for efficient storage and transmission, and then decompressing that data at the receiving end for smooth playback. Without this fundamental technology, the scale and quality of today’s video-driven digital ecosystem would be impossible.
The increasing demand for higher resolutions, HDR, high-frame-rate content, and AI-driven video applications is pushing codec innovation beyond traditional standards. Today’s ecosystem includes established codecs such as H.264/AVC and HEVC, along with emerging solutions such as AV1, EVC, LCEVC, and VVC/H.266. Future codec development is expected to focus on AI-assisted compression, energy efficiency, and support for advanced media experiences.
2. Problem Statement
The rapid growth of 4K/8K video, HDR, immersive media, cloud gaming, and AI-generated content is driving unprecedented data demands, putting pressure on bandwidth, storage, and content delivery infrastructure. While Modern codecs such as VVC/H.266 and AV2 deliver significant compression gains, they introduce higher encoding complexity, processing requirements, and power consumption, creating challenges for real-time applications and large-scale deployment.
The expanding multi-codec ecosystem, including H.264/AVC, HEVC, AV1, EVC, LCEVC, VVC, and AV2, also creates interoperability, licensing, and adoption challenges. Future solutions will require advances in AI-based compression, neural video coding, hardware acceleration, and system optimization to achieve scalable, cost-effective, and energy-efficient video delivery.

3.1 Historical Timeline of Video Codec
The figure below presents the historical timeline of video coding standards over time.
3.2 Additional Video Coding Standards
Other emerging video coding standards, such as EVC and LCEVC, provide alternative approaches to improving compression efficiency and are discussed below.
Since the introduction of the MPEG-1 standard, numerous video codecs have been developed to address evolving multimedia requirements. Most major video coding standards have been jointly developed and standardized by the ITU-T and ISO/IEC through collaborative efforts. Under ISO/IEC, these standards are identified through the MPEG framework, including MPEG-1, MPEG-2, MPEG-4, MPEG-H, MPEG-I, and MPEG-5. Many standards are also jointly specified with ITU-T and carry the H.26x designation, where the series currently extends from H.261 to H.266. Table 1 summarizes selected video coding standards.
3.2 Next-generation Video Coding (Beyond VVC)
Beyond VVC is the next-generation video coding standard currently under development by the Joint Video Experts Team (JVET), a collaboration between ITU-T and ISO/IEC MPEG. It is intended to succeed H.266/VVC and is targeted for completion around 2029. Driven by technologies like Enhanced Compression (ECM) and Neural Network Video Coding (NNVC), this new frontier will set the stage for the future of digital media. Current research for Beyond VVC focuses on ECM, NNVC and Neural Network-Enhanced Hybrid Video Coding.
