Product Description

2160P 24 in 1 H. 265 HDMI Low Bitrate 4K IPTV Encoder

Product Overview
 

HP825H 24 in 1 H.265 HD/SD Encoder is Catcast' professional audio&video encoding and multiplexing device. This device has 24 HDMI input interfaces, It supports HEVC/H.265 and MPEG-4 AVC/H.264 Encoding,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 2160P 30Hz resolution. Moreover, this device can simultaneously encode 24 channels audio& video signals and can multiplex stream through ASI and IP port. In conclusion, its high performance and cost-effective design make this device widely used in CATV digital head-end, Satellite and terrestrial digital TV, Business application, IPTV/OTT system, etc.

Catcast 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.


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".
