Advantages of H.266 (VVC) | Disadvantages of H.266 (VVC)

This page covers advantages and disadvantages of H.266 (VVC) Versatile Video Codec. It mentions benefits or advantages of H.266 (VVC) and drawbacks or disadvantages of H.266 (VVC).

Introduction: H.266 is a video compression standard developed by JVET (Joint Video Experts Team) in 2020. It has been developed based on techniques used in its predecessor H.265. It uses more advanced techniques to achieve high level of compression at same video quality supported by other standards.

Following are the features of H.266 (VVC).
• 50% better compression over H.265/HEVC
• HD/UHD/8K resolution video
• 10 bit / HDR
• 360 degree video encoding/decoding
• AI (Artificial Intelligence) based encoding
• Bit depths : up to 16 bits per component
• 81 modes in intra-prediction
• DCT2 (up to 64x64) + MTS transform
• Entropy coding : CABAC + dependent scalar quantization + LUT based CAE
• Loop filters : de-blocking, SAO, ALF, LMCS
• Other features : Screen content (text and graphics), adaptive resolution change, scalability, Tile based streaming, YCbCr/RGB 4:4:4, YCbCr 4:2:2 etc.

Benefits or advantages of H.266 (VVC)

Following are the benefits or advantages of H.266 (VVC):
➨It offers improvement in compression efficiency which is half of H.265/HEVC standard. Hence it requires less bandwidth to transmit same amount of video data compare to H.265.
➨It supports resolutions up to 8K which delivers high quality video for large screen displays and VR (Virtual Reality).
➨It supports HDR (High Dynamic Range) video which delivers greater contrast and better color accuracy in video contents.
➨It supports improved error resilience which results into more consistent and reliable video playback experience for the users.
➨It is compatible with existing video codecs and hence it is easy for video creators to adopt H.266 video codec.
➨It offers better video quality compare to H.265/HEVC due to higher resolution, higher frame rate and higher bit depths.
➨As it supports 360 degree video encoding, it has become popular for VR/AR applications. This delivers more immersive and interactive video experience for the users.

Drawbacks or disadvantages of H.266 (VVC)

Following are the drawbacks or disadvantages of H.266 (VVC):
➨As this is latest video codec, it is not widely supported by all the streaming devices, video players etc.
➨As use of this codec is subject to patent licensing, manufacturers have to pay high royalties.
➨It requires more provessing power compare to previous codecs.
➨It offers improved compression efficiency at the cost of increased complexity. Hence it is more difficult and time consuming for video content creators to encode video content having higher resolution and higher frame rate.
