H.264
H.264, also known as MPEG-4 Part 10, Advanced Video Coding, is a compression standard. Without
compressing image quality, it increases compression
rao and reduces the size of video le than
MJPEG or MPEG-4 Part 2.
H.265
H.265, also known as High Eciency Video Coding (HEVC) and MPEG-H Part 2, is a compression
standard. In comparison to H.264, it oers beer video compression at the same resoluon, frame
rate and image quality.
MJPEG
Moon JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding
technology is used. Images in a MJPEG format is compressed as individual JPEG images.
Prole
This funcon means that under the same bitrate, the more complex the prole is, the higher the
quality of the image is, and the requirement for network bandwidth is also higher.
I-Frame Interval
I-frame interval denes the number of frames between 2 I-frames.
In H.264 and H.265, an I-frame, or intra frame, is a self-contained frame that can be independently
decoded without any reference to other images. An I-frame consumes more bits than other
frames. Thus, video with more I-frames, in other words, smaller I-frame interval, generates more
steady and reliable data bits while requiring more storage space.
SVC
Scalable Video Coding (SVC) is the name for the Annex G extension of the H.264 or H.265 video
compression standard.
The
objecve of the SVC standardizaon has been to enable the encoding of a high-quality video
bitstream that contains one or more subset bitstreams that can themselves be decoded with a
complexity and reconstrucon quality similar to that achieved using the exisng H.264 or H.265
design with the same
quanty of data as in the subset bitstream. The subset bitstream is derived
by dropping packets from the larger bitstream.
