Understanding H.263
H.263 is a video compression standard defined by ITU-T (International Telecommunication Union Telecommunication Standardization Sector). It belongs to the H.26X series family. H.263 video codec is designed specifically for video compression in remote conferencing. The core technology of H.263 is that it can compress and transmit video at a lower bitrate.
Due to H.263 focusing on breakthroughs in compression and transmission and compression efficiency, it doesn’t have high requirements for video quality. Besides, H.263 can not only be used in video conferencing, but also applies to Flash video on the internet in the early years.
Understanding H.264
H.264 (Advanced Video Coding/AVC) is the successor of H.263. It is a video compression standard that is commonly used nowadays. The core trait of H.264 is that it is based on block-oriented, motion-compressed coding, which means it maintains the variation in frame rates instead of repeatedly recording pixels.
H.264 boosts the video quality based on H.263. Plus, it has stronger compatibility, especially well-compatible with various platforms on networks and systems, such as online streaming, video conferencing, broadcast, and physical media.
H263 vs H264: What Are the Key Differences
What are the differences between H263 and H264 codecs? The following section will tell you the comparisons in terms of compatibility, compression efficiency, and latency.
#1. Compatibility
H.264 outperforms H.263 in compatibility. H.263 is better suitable for early video conferencing and hardware. However, it is no longer popular nowadays. H.264 supports HD streaming, Blu-ray, and modern video calls. It is also compatible with various devices and browsers, such as smartphones, PCs, Google Chrome, and Safari.
#2. Compression Efficiency
H.264 is more efficient than H.263. H.263 can compress video size at low bitrates while ensuring smooth playback. H.264 not only does what H.263 can do, but it also provides high-quality video and optimizes the viewing experience.
#3. Latency
H.264 is better than H.264 in latency and real-time performance. H.263 offers low-latency and smooth video playback at a low bitrate, which is vital for video conferencing. H.264 supports high resolution and frame rate in the video, enabling users to enjoy a better experience.
Based on the comprehensive comparison results between H.263 and H.264, H.264 is the most worthwhile codec to choose.
