Thor Broadcast H-1SDI-DVBT-IPLL 1 SDI to DVB-T Modulator

Thor HD-SDI 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 HD-SDI 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.

Digital Video Broadcast: Terestrial DVB-T Modulation Standard

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.

DVBT-IPLL: Low Latency Encoding Option

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 300/700-1200 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.
