What is VVC?

VVC stands for Versatile Video Coding, which is a video coding standard developed by the Joint Video Experts Team (JVET), a collaboration between the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). VVC is the successor to the widely used video compression standard, HEVC (H.265), and aims to provide even higher compression efficiency and improved video quality.

Here are some key features and characteristics of VVC:

1. Improved Compression Efficiency: VVC offers significant improvements in compression efficiency compared to its predecessors. It achieves this by incorporating advanced coding techniques, including more sophisticated motion estimation, enhanced intra-prediction modes, and improved entropy coding. These advancements allow for further reduction in file sizes while maintaining high-quality video.

2. Support for High-Resolution and High-Dynamic-Range (HDR) Content: VVC is designed to support a wide range of video resolutions, including standard definition, high definition, 4K, and even 8K Ultra HD resolutions. It also includes features to handle High-Dynamic-Range (HDR) content, which provides a broader and more accurate range of colors and brightness levels.

3. Versatile Application and Compatibility: VVC is designed to be versatile, making it suitable for various applications and platforms. It is compatible with different types of devices, ranging from smartphones and tablets to smart TVs and streaming media players. VVC supports adaptive streaming and can adapt video quality based on network conditions and device capabilities.

4. Computational Complexity: Given the advanced compression techniques employed in VVC, the decoding process is more computationally intensive compared to previous video codecs. However, ongoing efforts are being made to optimize and accelerate VVC decoding through hardware support and efficient software implementations.

5. Licensing Considerations: VVC is subject to patent licensing, similar to previous video codecs like HEVC. Organizations utilizing VVC may need to obtain appropriate licenses to ensure legal compliance and royalty payments to the patent holders.

VVC represents a significant advancement in video compression technology, offering improved compression efficiency and video quality. Its capabilities make it well-suited for various applications, including streaming services, video-on-demand platforms, video conferencing, broadcasting, and more. As VVC continues to evolve and gain industry support, it has the potential to play a significant role in delivering high-quality video content in the future.
