Digital HDTV channels are simple to distribute over coax and are visible on any TV without needing video adapters or set top boxes. Thor HDMI to DVB-T modulators are combination devices that bundle real time HD hardware encoders with a managed program stream multiplexer and agile RF QPSK modulator. Each chassis can encode up to 4 channels of HDMI video to MPEG-2 or H.264 and modulate the programs on up to 4 DVB-T carrier outputs. In addition to the encoded programs, the unit can also modulate programs encoded externally via an ASI input. This platform is most commonly used by large organizations or broadcasters that own SDI matrix routers. This platform is ideal for corporate MATV systems or in house HD video distribution from SDI sources. This platform is not recommend for broadcast headend signal origination due to lack of 708 closed captioning support. For broadcasters requiring government mandated 708 captioning and Dolby AC/3 audio please contact a sales representative.
The DVB-T standard is the worlds most widely adopted radio frequency modulation standard for digital video broadcast over terrestrial systems. This standard is used throughout the world for both cable and over the air digital video broadcast systems. The standard was first used in the United Kingdom, and has since gained in acceptance in over 90 worldwide countries. This standard supports the original DVB-T modulation protocols for both QPSK and QAM16/64. This chassis outputs either 2 or 4 adjacent RF carriers and can distribute programing anywhere between those channels. The unit also supports ingestion of externally encoded programing via the ASI input. The ASI input can be parsed for up to 120 Mbps of incoming programing based on model hardware and software selection.
The HDMI video standard is commonly found in consumer and profesional devices all over the world. It is a versitile connector with many parallel lines for bi-directional communication. The latest standards support full rate HD video at 1080p60 with new standards being released to support ultra high resolution 4K video. Thor encoder cards support any HDMI input from any device that provides HD video output in standard HDTV resolutions and aspect ratios.
Unit model numbers that include "LL" indicate that model includes Thor’s low latency encoding option. This new feature reduces the time delay between video input and encoded program output by more than 10 times. Standard model encoder modulator chassis systems typically have an encoding latency of 700-1200 ms depending on encoding parameters and output configurations. For many applications, adding approximately 1 second latency doesn’t make a difference. For other applications, such as live events; 1 second delay is very noticeable and prevents modulation from being used in distribution systems. The solution to live video broadcast applications is the Low Latency upgrade option for the encoders. IPLL models typically have an encoding latency of approximately 70-110ms, making them suitable for distribution of live video events. Contact a Thor sales representative today for more information on encoding latency.
Thor HDMI-DVBT-IP line of encoder modulators are designed for high quality distribution of broadcast quality video over coax cable. These systems are available in many configurations for a wide range of applications. This page covers models for a specific input video type combined with a modulator chassis programed for a specific output format. It is important to note that encoder card types can usually be combined with encoder cards for other video types. For custom model configurations please contact Thor directly for pricing and availability. While most firmware for Thor modulator chassis is inter-compatible; not all hardware will work with all software. Thor representatives are available for free design and consultation service. If you have any questions or concerns about a Thor system, contact a representative directly at 1-800-521-8467.
