HP8224H
Catcast
HP8224H HEVC/H.265 AVC/H.264 to IP Encoder
Product Outline
HP8224H is Catcast's new generation of HEVC/H.265 & MPEG 4 AVC/H.264 encoder which is developed based on EHP200 platform. It supports up to 3*H.265/H.264 encoding modules with 4 HDMI interfaces on each module. With B frame (IBBP) GOP structure and advanced compressing algorithm, this device enhances picture quality and provides ultra low bitrate to save 75% bandwidth compared with H.264/AVC and it supports up to 1080P 60Hz resolution.
It also has 1 data port (1000M/100M) for IP output (1 MPTS and max 4 SPTS per module) over UDP/RTP/RTSP protocol and 1 Network Management port to manage the 3 modules individually through 3 different IP addresses.
In conclusion, its high performance and cost-effective design make this device widely used in CATV digital head-end, business application, IPTV/OTT system, etc.

HEVC/H.265 encoder’s advantages
1. Providing smooth TS for modulators
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 for modulators. It is widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
2. Encoding with highest compression format—B frame (IBBP) What is B Frame?
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”
