Dexin HEVC/H.265 encoder’s advantages
KUNUOMAGIC HEVC/H.265 encoder adopts Fujitsu chip which offers stable bitrate with lower fluctuation compared with other encoding chips, so it provides smooth TS for modulators. Itis widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
What is B Frame?
Thereare 3 major picture types used in the different video algorithms, they are I, P and B.
They are different in the following characteristics:
I‑frames are the least compressible but don't require other video frames to decode.
P‑frames can use data from previous frames to decompress and are more compressible than I‑frames.
B‑frames can use both previous and forward frames for data reference to get the highest amount of data compression.
