The DCH-3000ECDVB encoder features real-time MPEG-2 encoding, compressing one analog audio and video signal into an MPEG-2 transport stream; it outputs a DVB-ASI transport stream (comesoon).
The encoding bitrate is adjustable from 1.5 to 20 Mbps depending on different application scenarios, compatible with NTSC and PAL signal inputs. With a 19" standard rack mount, the DCH-3000EC is your best choice for various digital cable/wireless television front-end systems. Features include full compliance with international MPEG-1 (ISO/IEC11172-2),MPEG-2 MP@ML encoding(ISO/IEC13818-2)* Video compression uses MPEG-2 4:2:0MP@ML, with a bitrate of 1.5 Mbps to 20 Mbps, adjustable GOP frame format; audio is compressed using MPEG1 Layer1 and Layer2 algorithms. * The front panel indicator lights display power status, serial data input circuit operational status, and encoding signal input circuit operational status. * LCD screen display and user-friendly interface. Model DCH-3000EC-30 (with SDI input, includes MUX, supports HDMS) DCH-3000EC-40 (with SDI input, includes MUX, supports HDMS, with a 100Mbps network card, supports IP output). Features include full compliance with international MPEG-1 (ISO/IEC11172-2), MPEG-2MP@MLencoding (ISO/IEC13818-2)* Video compression uses MPEG-2 4:2:0MP@ML, with a bitrate of 1.5 Mbps to 20 Mbps, adjustable GOP frame format; audio is compressed using MPEG1 Layer1 and Layer2 algorithms. * Encoding inputs: analog S-terminal S-Video and composite video Composite Video dual input, as well as stereo audio input. * Supports SDI (embedded audio) interface input. * Features stream remultiplexing capability, allowing two MPEG-2 transport streams (TS streams from the ASI input port and TS streams generated by the MPEG-2 encoder) to be multiplexed into a single multi-program transport stream (MPTS). * Automatically generates PAT and PMT based on user selection; under network management software control, can edit and insert NIT and SDT. * Front panel indicator lights display power status, serial data input circuit operational status, and encoding signal input circuit operational status. * LCD screen display and user-friendly interface. * Based on SNMP protocol, supports PBI HDMS network management system. * IP output functionality (40 series).
