4 HD-SDI Broadcast Encoder IPTV and ASI Out MPEG2 / H.264 / AC3/ 1080p / CC

H-4HD-EMS 4 Ch HD-SDI Program Encoder

Real-Time Encoder for 4 HD-SDI to MPEG-2 or H.264 on ASI or IP with CC & AC/3

Designed as a companion encoder for the popular QAM-IP series of encoder modulators, Thor H-4HD-EMS series HD program encoders accept up to 4 channels of uncompressed HD-SDI digital video on 4 BNC connectors. Managed through any modern web browser, each encoder can be independently adjusted for bitrate, codecs, and video image quality. Encoding support for the MPEG-2 codec, along with Dolby AC/3 audio, ensures that the programs generated by this encoder can be viewed by virtually every TV in the United States. All four program streams are multiplexed into an ASI MPTS output on mirrored BNC terminals. The ASI output can be directly connected to the ASI input on a QAM-IP digital TV channel modulator. This allows additional programs to be added to the QAM-IP output channels as additional "virtual" or "sub" channels. On a TV, this will appear as channels 2.1, 2.2, etc. Each digital channel can carry as many as 20 programs, depending on resolution and encoded bit rate. In addition to the ASI output, the program streams are also available as UDP or RTP network video transport streams. This output is fully compliant with IGMP Multicast UDP MPEG-TS standards and can be easily injected into almost any IPTV system. The stream is a universally accepted format and can easily be viewed in client applications such as VLC. In addition to network management on a dedicated NMS Ethernet port, all settings and menu configuration items can easily be viewed or adjusted from the front panel LCD and keypad. LEDs are also provided for alarm monitoring and input video detection.
