micro BNC
Miniaturized version of a standard BNC connector, allowing for higher connector density.
Please note that DekTec does not supply micro-BNC to BNC patch cables with these boards. For best performance, do not use patch cables. Instead, system-interconnect cables should be directly fitted with micro-BNC connectors. |

Bidirectional ports
ASI/SDI port that can be configured from software, as input or output, and as SDI or ASI.
Each ports can be configured independently from the other ports.

3G-SDI level A+B
Standard: SMPTE ST 425-0:2014
Professional serial digital interface (SDI) operating at a nominal rate of 3Gbit/s. ST 425 describes three different mapping schemes for transporting video, audio and ancillary data into SDI. DekTec SDI cards support both level-A direct mapping and level-B dual link (B-DL) mapping. 3G-SDI is used to transport uncompressed progressive HD video (1080p50/60) over a single coax cable over a distance of up to 150m. |

DVB-ASI
Standard: EN 50083-9:2002

| Features |
Relay bypass
Hardware relay that automatically connects the SDI/ASI input to the output upon
an application crash or PC power failure. This feature enables highly-available
system configurations without requiring an external failover switch.
|
Genlock
Method to synchronize SDI outputs to a 'genlock' signal that is connected to
the genlock input port of the card. Both bi- and tri-level sync signals are
accepted.

|
Payload identifier
Standard: SMPTE ST 352:2013
The "payload identifier" is an ancillary data packet that describes the characteristics of the SDI signal, including the picture rate, sampling structure, aspect ratio, bit depth and link assignment. The Matrix API allows easy insertion/or and extraction of the payload identifier. |

4K 2SI mapping
Standard: SMPTE ST 425-5:2015, ST 435-1:2012
2-sample interleave division, a method to map a 4K image to four sub-images. 2SI is defined in ST-435-1. Each sample in a 2x2 block is put in a different sub-image. Each sub-image contains the full image, downsampled by a factor of 2 in horizontal and vertical direction. 2SI is the offical method prescribed by SMPTE ST 425-5, but in practice the informal quadrants method is used a lot. |
|||||
|
4K quad link
Standard: SMPTE ST 425-5:2015
Method to transport 4K images over four 3G-SDI links. DekTec cards support two mappings from 4K images to four links: 4K 2SI mapping and "4K quadrants" mapping. The mapping method can be selected by software. |
|||||
|
4K quadrants
Standard: SMPTE ST 425-5:2015, ST 435-1:2012
The "4K quadrants" method maps 4K images to four sub-images on four 3G-SDI links where each sub-image is one quadrant (one quarter) of the 4K image. This method is described in Annex B of the ST 425-5 standard. This is an "informative" (=not normative) annex, yet in practice this method is used a lot. |
|||||
|
4K to HD scaling
Scaling 12G-SDI to 3G-SDI in hardware. The 4K UHD image is scaled down by a
factor of 2 horizontally and vertically. HANC and VANC are taken from sub-image
1 (quadrant 1) in the 12G-SDI image. The software receives 3G-SDI, reducing PCIe
bus bandwidth by a factor of 4. This feature can be used for monitoring or for
creating a mosaic of 12G-SDI signals.

#Audio channels
For SD and HD formats, the maximum number of audio channels is 16. For full HD
(3G-SDI) it is 32 and for UHD 128 channels of audio are supported. Matrix API
allows easy insertion (embedding) or extraction of all audio channels.

Audio bit depth
Standard: SMPTE ST 272M:200
Each audio channel can carry 16, 20, or 24 bits per audio sample. |

Dolby® D/E
Standard: SMPTE ST 337:2015
Each audio channel can carry Dolby D/E® compressed audio (non PCM audio). Matrix API allows easy insertion/or and extraction of Dolby® D/E data. |

Ancillary data
Standard: SMPTE ST 291M:2011
Ancillary data (also: ANC data) is non-video information embedded in an SDI stream. The DekTec Matrix API reads all ANC data packets present in an SDI frame and makes them available to your application, optionally filtered by DID (Data Identifier) and SDID (Secondary Data Idenfier). Audio is also ANC data, but for ease of use, the Matrix API supports audio with dedicated data structures and API functions. |
|||||
|
Closed captioning
Standard: SMPTE ST 334-1
ST 334-1 defines the structure of packets carrying CEA-708, as well as CEA-608 closed captioning data, time code data, and ATSC A/65 closed caption descriptor information. Ancillary data packets with closed captioning are available to your application via the Matrix API by filtering on DID=0x61 and SDID=0x101 (CEA-708) or SDID=0x102 (CEA-608). |
|||||
|
HDR/WCG metadata
Standard: SMPTE ST 2108-1:2018
ST 2108 defines the transport of High Dynamic Range (HDR) and Wide Color Gamut (WCG) metadata in ancillary data packets. These HDR/WCG packets are available to your application via the Matrix API by filtering on DID=0x41 and SDID=0x0C. |
|||||
|
Time code
Standard: SMPTE ST 12-1:2014, ST 12-2:2014
ST 12-1 and ST 12-2 specify the format of time codes to label video frames, and the way time codes are encoded in ancillary data packets. Time codes in ancillary data packets are available to your application via the Matrix API by filtering on DID=0x60 and SDID=0x60. |
|||||
|
VBI data
Standard: SMPTE ST 2031:2007
ST 2031 specifies how to carry VBI data, such as subtitles, teletext, AMOL, CEA-608, OP-47 (known by SMPTE as RDD-08), SCTE 127, VITC and WSS, as ancillary data packets in the vertical ancillary data space (VANC). Ancillary data packets with VBI data are available to your application via the Matrix API by filtering on DID=0x41 and SDID=0x08. |
