Product Overview

多路转码器

With the number of channel increasing fast, DTV operators require the ability to have a multi-channel transcoding solution to simplify their headend architecture and to reduce the amount of headend equipment needed. To achieve this, they need products able to deal with multi-channel MPEG-2 and MPEG-4 AVC video streams.

GOSPELL’s GN-1772 a new generation of modular & high density SD video and audio conversion unit with best-in-class video quality. It supports up to 36/72 channels MPEG-2/MPEG-4 AVC SD live video and audio services transcoding with IP in and out by using six external pluggable transcoding modules for broadcast and Over-The-Top(OTT) applications.

GN-1772 supports web browser and SNMP management for local and remote monitoring and controlling that can greatly reduce management time and operating expense (OPEX) of operators.
