What is MPEG-5 (EVC & LCEVC)?

MPEG-5 is one of the newest generations of video compression standards created to improve streaming quality while reducing bandwidth usage and processing demands. As online video continues to dominate internet traffic, modern codecs are under pressure to deliver higher resolutions, lower latency, and better efficiency across smartphones, TVs, browsers, and cloud platforms.

Unlike previous MPEG standards that focused on a single codec, MPEG-5 introduced two separate technologies designed for different purposes. MPEG-5 Part 1, called Essential Video Coding (EVC), focuses on efficient compression with simplified licensing. MPEG-5 Part 2, known as Low Complexity Enhancement Video Coding (LCEVC), improves existing codecs by adding an enhancement layer that boosts quality without requiring heavy hardware upgrades.

Both technologies were developed to address problems that appeared after the rise of 4K, HDR, mobile streaming, cloud gaming, video conferencing, and live broadcasting. While codecs such as H.264, H.265/HEVC, AV1, and VVC continue competing for dominance, MPEG-5 aims to offer more flexible and practical alternatives for the modern streaming ecosystem.

What is MPEG-5?

MPEG-5 is a video coding standard developed by the Moving Picture Experts Group (MPEG), the same organization behind MPEG-2, MPEG-4, and H.264/AVC. Officially introduced in 2020, MPEG-5 differs from earlier MPEG standards because it contains multiple independent parts rather than a single codec.

The standard currently includes:

• MPEG-5 Part 1 - Essential Video Coding (EVC)
• MPEG-5 Part 2 - Low Complexity Enhancement Video Coding (LCEVC)

These technologies solve different challenges in video delivery.

EVC was designed as a royalty-friendly alternative to HEVC and AV1. It aims to provide strong compression performance while avoiding the complex patent licensing disputes that slowed HEVC adoption.

LCEVC takes a completely different approach. Instead of replacing existing codecs, it enhances them. LCEVC adds an extra processing layer that improves visual quality and reduces computational load. This means streaming providers can upgrade quality without rebuilding their entire infrastructure.

MPEG-5 arrived during a period when the video industry was becoming fragmented. Streaming services, device manufacturers, cloud providers, and broadcasters needed more flexible technologies that could work across different hardware generations. MPEG-5 was created partly to solve this fragmentation problem.

The standard is particularly relevant for:

• 4K and 8K streaming
• Cloud gaming
• Video conferencing
• Live sports broadcasting
• Mobile streaming
• Low-latency streaming
• OTT platforms
• Virtual reality and immersive media

Although MPEG-5 is not yet as widely adopted as H.264 or AV1, its technologies are attracting interest because they target practical deployment challenges rather than focusing only on maximum compression efficiency.

MPEG-5 Part 1: EVC (Essential Video Coding)

Essential Video Coding, usually shortened to EVC, is a modern video codec created by MPEG as a successor and alternative to earlier compression standards such as AVC and HEVC.

The primary goal of EVC is to deliver better compression efficiency while simplifying patent licensing. This was one of the biggest motivations behind the project.

HEVC offered major bitrate savings compared to H.264, but its adoption became complicated because multiple patent pools demanded licensing fees. Some companies avoided HEVC entirely because licensing costs and legal uncertainty created risks for large-scale deployment.

EVC attempts to solve this by splitting the codec into two profiles:

• Baseline Profile
• Main Profile

Baseline Profile

The Baseline Profile contains only technologies that are either royalty-free or whose patents have expired. This makes it easier for developers and companies to deploy EVC without complicated licensing negotiations.

The Baseline Profile delivers compression performance similar to older codecs while maintaining broad compatibility and legal simplicity.

Key characteristics include:

• Lower licensing concerns
• Simplified implementation
• Reduced complexity
• Broad deployment potential
• Suitable for software decoding

Main Profile

The Main Profile introduces advanced compression tools that improve efficiency beyond the Baseline Profile. These tools may require patent licensing, but they significantly reduce bitrate requirements.

Main Profile EVC can achieve compression efficiency close to HEVC while maintaining lower computational complexity in some scenarios.

Features may include:

• Advanced motion compensation
• Improved intra prediction
• Enhanced transform coding
• Adaptive filtering
• Better entropy coding

Compression Performance

EVC generally performs better than AVC/H.264 and competes with HEVC in many use cases. Depending on encoder implementation and content type, EVC can reduce bitrate requirements by around 25% to 50% compared to AVC while maintaining similar visual quality.

The codec is optimized for:

• High-resolution streaming
• HDR video
• Real-time communications
• Low-latency applications
• Mobile playback

Hardware and Software Support

One challenge facing EVC is ecosystem adoption. Existing devices already support AVC, HEVC, VP9, and increasingly AV1. Hardware manufacturers are cautious about adding support for another codec unless there is strong industry demand.

However, EVC's lower complexity can help with software decoding and mobile applications where battery life and CPU usage are important.

Advantages of EVC

• Better compression than AVC
• Simplified licensing structure
• Lower decoding complexity than some modern codecs
• Flexible profiles for different markets
• Suitable for streaming and broadcasting

Disadvantages of EVC

• Limited industry adoption so far
• Less hardware acceleration availability
• Competes against AV1 and VVC
• Smaller ecosystem compared to HEVC

MPEG-5 Part 2: LCEVC (Low Complexity Enhancement Video Coding)

Low Complexity Enhancement Video Coding, or LCEVC, is one of the most unusual video compression technologies developed in recent years. Instead of functioning as a standalone codec, LCEVC works as an enhancement layer added on top of another codec.

This means LCEVC does not replace AVC, HEVC, AV1, or VVC. Instead, it improves them.

The technology was originally developed by V-Nova and later standardized as MPEG-5 Part 2.

How LCEVC Works

LCEVC uses a two-layer architecture:

• Base layer
• Enhancement layer

The base layer is encoded using an existing codec such as H.264, HEVC, AV1, or VP9 at lower resolution or lower quality. LCEVC then adds enhancement information that reconstructs higher visual quality during playback.

This approach significantly reduces computational complexity because the underlying codec does not need to work as aggressively.

As a result:

• Encoding becomes faster
• Decoding uses less power
• Streaming quality improves
• Latency can be reduced

Why LCEVC Is Different

Most modern codecs focus entirely on improving compression algorithms inside a single codec pipeline. LCEVC changes the strategy by splitting processing between a lightweight base codec and an enhancement stage.

This creates several advantages:

• Existing hardware can still be used
• Infrastructure upgrades are easier
• Streaming providers can improve quality without replacing entire systems
• Mobile devices consume less power

For example, a streaming service using H.264 infrastructure can deploy LCEVC to improve quality without requiring users to purchase new devices.

Performance Benefits

LCEVC can improve both visual quality and efficiency. In many cases, it delivers:

• Lower bitrate for the same quality
• Higher quality at the same bitrate
• Reduced CPU usage
• Faster encoding speeds
• Lower latency

This makes the technology attractive for live streaming and cloud gaming where low latency matters as much as compression efficiency.

Use Cases for LCEVC

LCEVC is particularly useful in environments where upgrading hardware is expensive or impractical.

Common use cases include:

• OTT streaming platforms
• Cloud gaming
• Mobile streaming
• Video conferencing
• Live sports streaming
• Remote production workflows
• Legacy device compatibility

Advantages of LCEVC

• Works with existing codecs
• Lower computational complexity
• Faster encoding
• Lower power consumption
• Compatible with older hardware
• Improved streaming scalability

Disadvantages of LCEVC

• Requires enhancement layer support
• Not universally supported yet
• Depends on underlying codec performance
• Some workflows may need software updates

EVC vs. LCEVC

Although both belong to MPEG-5, EVC and LCEVC are fundamentally different technologies.

EVC is a standalone codec designed to directly compete with AVC, HEVC, AV1, and VVC. Its focus is on efficient compression with more manageable licensing.

LCEVC is an enhancement technology that works together with existing codecs rather than replacing them.

Core Difference

• EVC replaces traditional codecs
• LCEVC enhances traditional codecs

Complexity

EVC uses advanced compression algorithms similar to other modern codecs. LCEVC reduces complexity by offloading part of the processing into an enhancement layer.

Deployment Strategy

EVC may require new encoder and decoder support. LCEVC can often work with existing infrastructure and hardware.

Target Markets

EVC is aimed at companies looking for a next-generation codec alternative. LCEVC targets organizations seeking immediate quality improvements with minimal infrastructure changes.

Industry Adoption

LCEVC has gained attention from streaming and broadcasting companies because deployment can be easier. EVC faces stronger competition because the codec market already includes HEVC, AV1, and VVC.

Why MPEG-5 Matters for the Future of Streaming

Video streaming continues to grow every year. Platforms now deliver 4K HDR movies, live sports, user-generated content, video calls, and cloud gaming sessions to billions of devices worldwide.

This creates enormous technical challenges:

• Bandwidth costs
• Network congestion
• Device compatibility
• Power consumption
• Low-latency delivery
• Infrastructure scaling

MPEG-5 technologies were designed specifically for these modern challenges.

EVC offers a possible path toward more predictable codec licensing and efficient compression. This matters for companies that want alternatives to complicated HEVC licensing structures.

LCEVC addresses another major problem: the cost of replacing hardware. Many streaming providers already operate huge encoding infrastructures. Replacing everything for a new codec can take years and cost millions of dollars.

By enhancing existing codecs instead of replacing them, LCEVC creates a more practical upgrade path.

The future of video delivery will likely involve multiple codecs working together rather than a single universal standard. Different applications have different priorities:

• Mobile devices prioritize battery efficiency
• Cloud gaming prioritizes low latency
• Streaming services prioritize bandwidth savings
• Broadcasters prioritize reliability
• Video conferencing prioritizes real-time responsiveness

MPEG-5 technologies help address this diversity.

Even if MPEG-5 never completely replaces existing standards, its ideas are already influencing the broader video industry. Simplified licensing, scalable enhancement layers, and low-complexity streaming are becoming increasingly important as video consumption expands worldwide.
