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.

SVC enables forward

compability for older hardware: the same bitstream can be consumed by

basic hardware which can only decode a

low-resoluon subset, while more advanced hardware

will be able decode high quality video stream.
