Catcast HEVC/H.265 encoder’s advantages
1. Providing smooth TS
Catcast HEVC/H.265 encoder adopts Fujitsu chip which offers stable bitrate with lower fluctuation compared with other encoding chips, so it provides smooth TS, It is widely used in variety of distribution systems such as CATV digital head-end, IPTV head-end, satellite and terrestrial digital TV, etc.
There are 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
Frame Type |
Byte of data/KB |
Compression Ratio |
I | 18 | 7:1 |
P | 6 | 20:1 |
B | 2.5 | 50:1 |
In one word, B frame is the highest compression format which makes it possible to process HD video at low bit rate. HEVC/H.265 encoder is not able to save bandwidth unless it is with B frame. In encoder parameters, B frame is often described in GOP (Group of Pictures) structure, like “IBBP”.
