Thor part number H-4HDMI-QAM-IP is a standard QAM-IP Chassis equipped with 2 Dual Channel HDMI encoder cards.  These cards have two HDMI inputs and encode two seperate HD programs each.  All four encoders can be configured independently.  This card supports native HD resolutions at 720i, 720p, 1080i, 1080p.  Frame rates up to 60fps are supported for all video resolutions.  The encoder parameters can be set through the web interface or via the front panel.  For the video codec, both MPEG-2 and H.264 can be selected, and the encoding rate is adjustable from 1-20 Mbps.  The audio encoding is through embedded HDMI audio input, and the encoding rate is adjustable from 64-320 kbps.  Thor also carries external audio embedded for use with external analog or digital audio sources if embedded HDMI audio is not available.   Other available settings are Program Name, Service ID, PMT PID, Video PID, Audio PID, and PCR PID.  These parameters are used for Electronic Programing Guide systems, and for program information display on the decoded content. 

THOR QAM-IP Chassis

Thor QAM-IP Real Time Encoders are designed to bridge the gap between digital content creators and their audience.  In today's world, digital video can be created by almost any device.  However, uncompressed digital video such as HDMI or SDI carries a tremendous amount of information.  In order to broadcast or distribute video it must be encoded.  Encoding compresses the video information to a manageable data rate so it can travel to the end user.  Digital TV channels use RF (Radio Frequency) signals to carry this encoded video information to a TV tuner or recording device.  This is how Digital Cable and Digital Over The Air TV services work.  However more and more content is now being delivered over IP networks such as the internet and private VPN's.  The QAM-IP platform is designed to bridge these previously separate content delivery mediums.  A single QAM-IP Real Time Encoder can deliver up to 4 channels of live video content as a standard digital TV channel while also providing a live internet stream to a Content Delivery Network (CDN) or local IPTV system.  

Thor QAM-IP series real time digital encoders are one of the most versatile encoding systems on the market.  An internal web server provides convenient access for management and monitoring with a web interface accessible through any standard web browser.  All settings are also available through the front panel.  Each QAM-IP system supports real time encoding of 1 to 4 channels of HD or SD content in a 1RU chassis.  Each video input is fed to a dedicated hardware encoder that can be independently configured for bit rate, codec, and program ID.  For broadcasting applications, the QAM-IP platform features an internal ASI multiplexer with add/drop abilities.  This allows externally encoded programs to be added to the units output, and can also be used for a broadcast contribution feed to a cable TV Headend system.  After selecting the desired programing through the management service, all content becomes available as live digital TV channels that can be set to any frequency from 2-135.  Thor offers firmware versions for all major world modulation protocols, such as QAM, 8VSB, DVB-T, DVB-C, and ISDB-T.  RF output power is a strong 45 dBmV, and the output can be adjusted through the web interface or front panel via an internal attenuator to as low as 15 dBmV.  The same content is also available as a live IP stream that can be sent over the internet to a CDN, Cloud Server, or local IPTV Media Server.  Thor offers assistance with configuration of internet cloud services, such as Amazon Web Services.  Contact a sales representative for more information.
