Pronunciation: [hˈɛvk] (IPA) 
The spelling of the word "hevc" is counterintuitive and may be confusing for some. However, it is based on the phonetic transcription of its full form, "High Efficiency Video Coding." The "h" sound represents "High," while "e" represents "Efficiency." The combination of "v" and "c" represents "Video Coding," with the "v" sounding like "vuh" and the "c" sounding like "kuh." Therefore, "hevc" is pronounced as "hɪ'vɛk" in IPA transcription.
HEVC (High Efficiency Video Coding) is a video compression standard that was developed to succeed the widely used H.264/MPEG-4 AVC compression format. It is designed to offer significant improvements in video compression efficiency compared to its predecessor. HEVC was jointly developed by the Video Coding Experts Group (VCEG) of the International Telecommunication Union (ITU-T) and the Moving Picture Experts Group (MPEG) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
HEVC utilizes advanced algorithms and techniques to significantly reduce the bit rate required for video streaming and storage while maintaining high video quality. This allows for more efficient transmission and lower storage requirements without degrading the visual experience. HEVC achieves a higher level of compression by dividing the video frames into smaller blocks and applying sophisticated encoding techniques that take advantage of both spatial and temporal redundancies.
The advantages of HEVC include improved video quality at the same bit rate compared to previous compression standards, or conversely, reduced bit rate requirements for the same level of quality. It also supports a wider range of video resolutions, including ultra-high definition formats such as 4K and 8K, making it suitable for high-resolution video streaming and broadcasting. Additionally, HEVC is highly compatible with various devices and platforms, ensuring broad support across different applications and services.
HEVC is widely used in various video-related applications, including video streaming services, digital broadcasting, video conferencing, and video surveillance systems. Its efficient compression capabilities make it an essential technology in the modern digital video landscape.
The term "HEVC" is an abbreviation for "High Efficiency Video Coding". Its etymology is derived from the two main components of the term: "High Efficiency" and "Video Coding".
- "High Efficiency" refers to the significant improvement in video coding efficiency achieved by the HEVC standard compared to its predecessor, H.264/MPEG-4 AVC. The goal of HEVC was to provide higher video compression ratios, enabling better video quality at lower bit rates or smaller file sizes.
- "Video Coding" pertains to the process of converting a video signal into a compressed digital format, allowing for efficient storage, transmission, and playback. HEVC is a video coding standard developed jointly by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG), with the aim of providing improved video compression algorithms.
