Thor Broadcast SDI-QAM-IP and SDI-QAM-IPLL Product Lines
Thor Broadcast HD-SDI to QAM modulators are combination devices that bundle real time HD hardware encoders with a managed program stream multiplexer and agile RF QAM 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 QAM carrier outputs. These are individual encoding channels that can be setup and operated in individual settings; inputs 1 and 2 can be setup in Mpeg2 and have 720i resolution while inputs 3 and 4 can be setup in H.264 and output 1080p. In addition to the encoded programs, the unit can also modulate programs encoded externally via an ASI input. Most notably Thor Broadcast utilizes some of the fastest encoding speeds in Mpeg2. When you're trying to broadcast SDI video over IP or RF, professionals in all backgrounds choose Thor for their paramount applications. Pro-DVB integration personnel's first choice in live video applications like the NFL, NBA, NHL, NASCAR circuits, and even F1 tracks around the globe all rely on Thor Broadast's fastest encoding speeds to ensure their viewers and fans all see the race as close to the real thing as possible. ;
QAM: Quadrature Amplitude Modulation (ITU-T J.83)
Thor encoder modulators are for all major world television systems. Quadrant Amplitude Modulation (QAM) is commonly used in cable TV systems due to its high bandwidth abilities. The International Telecommunications Union (ITU) defines the standards for QAM under the J.83 standard. Thor QAM-IP chassis support all three primary J.83 QAM standards; ITU-T J.83A, J.83B, and J.83C. Any QAM-IP chassis can be set to output RF carriers under either of these three standards without the need to change firmware. J.83A and J.83C are primarily used in European systems and are commonly known as DVB-C. US cable TV systems are based on J.83B, which in the United States is commonly referred to simply as "QAM". QAM-IP chassis are from Thor with many different types of video input and encoder cards. These encoder modules are independent of the modulator chassis system.
SDI-QAM-IPLL: Modulator Chassis with up 4 inputs at 3G-SDI 1080p60
SDI uncompressed digital video is commonly used in broadcasting and professional AV systems due to its convenience. Serial Digital video can be carried over single conductor coax cables and typically employ common BNC connectors. HD-SDI carries the same digital video data as HDMI, but without all complicated digital content protection (DCP) and HDCP trouble. Thor multichannel encoder modulator chassis systems support encoder card input configurations from 1 to 4 channels. These cards are now standard with Low Latency and Dolby Digital AC3.
QAM-IPLL: Low Latency Encoding Option
Thor's Low Latency encoding is now paramount in nearly every Live Sport on a global level; from the Olympics to Race Tracks, all inclusive 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(lab tested), making them suitable for distribution of live video events. Contact a Thor sales representative today for more information on encoding latency.
Encoder Card Compatibility between Modulator Chassis
Chassis systems with custom encoder card configurations are for supporting multiple input video formats in a single chassis. Thor SDI-QAM-IP line of encoder modulators are designed for high quality distribution of broadcast quality video over coax cable. These systems are 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. While most firmware for Thor modulator chassis is inter-compatible; not all hardware will work with all software.
