H.265
H.265, also known as High Eciency Video Coding (HEVC) and MPEG-H Part 2, is a compression
standard. In comparison to H.264, it
oers beer video compression at the same resoluon, frame
rate and image quality.
MJPEG
Moon 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.
Prole
This funcon means that under the same bitrate, the more complex the prole is, the higher the
quality of the image is, and the requirement for network bandwidth is also higher.
I-Frame Interval
I-frame interval denes 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
objecve of the SVC standardizaon 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
reconstrucon quality similar to that achieved using the exisng H.264 or H.265
design with the same quanty of data as in the subset bitstream. The subset bitstream is derived
by dropping packets from the larger bitstream.
SVC enables forward
compability for older hardware: the same bitstream can be consumed by
basic hardware which can only decode a
low-resoluon subset, while more advanced hardware
will be able decode high quality video stream.
