Multi-channel H.264 HD Encoding Modulator

Description

Overview

Buadcom Multi-channel H.264 HD Encoding & Modulator (all-in-one) is a high-density and flexible device, integrating Encoding up to 24*HDMI in, Multiplexing, Encapsulation and Modulation with its excellent performance of HD encoding and modulation. It supports various of modulation modules, Output RF DVB-T/DVB-C/ATSC/ISDB-T/DTMB for option. Meanwhile, it delivers unrivaled and reliable video quality with advanced video compression(H.264) technology, to meet the ever-increasing need of high quality video experiences. Moreover, with its multiplexing module, local programs can be re-multiplexed with external Transport Stream. Additional, the Encoding Modulator can be applied to IPTV system with TS over IP output/input. The device also supports program sources from HD STB, HD camera or playout server, PC and other diversified video source.
