Satellite Digital TV Encoder MPEG Transcoder For SD Video Conversion

Delivery Time:Within 7 days

8-Ch MPEG-2/MPEG-4 To MPEG-4/MPEG-2 Transcoder

Model No: GN-1738

Product Overview

With the number of video formats increasing fast, DTV operators require the ability to have a 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 both MPEG-2 and MPEG-4 AVC video streams from different sources.

GOSPELL GN-1738 transcoder is highly competitive SD video conversion unit with best in class video quality. It can convert up to eight channels of MPEG-2 (or MPEG-4 AVC) SD live video streams to MPEG-4 AVC (or MPEG-2) video formats. The GN-1738 provides a wide range of real time transport streams input options, from satellite, DVB-ASI and TS-over-IP inputs. This allows it handle any real time video source, and 1+1 redundant transcoding outputs via both IP and DVB-ASI are also introduced, enabling a highly reliable video service to be delivered. In addition, the GN-1738 supports Web and SNMP based management for conveniently local and remote management as well as maintenance.
