SDI stands for serial digital interference. It is a video interface used within broadcast environments and supports both SD and HD signals. It runs on a single co-ax cable with BNC terminations. As well as video, the signal carries audio and other ancillary data such as closed captions, content identification and test signals.
SDI is not found outside broadcast facilities so it will not be seen on domestic televisions or players.
In digital video broadcast (DVB), SDI is Serial Digital Interface an uncompressed form of A/V signal and ASI is Asynchronous Serial Interface an compressed form of A/V signal. The SDI signal hold the pids(audio, video, subtitle ...) of one channel, ASI can hold pids from multiple channels and in some cases (satelite uplink) some pids who describe the transponder(NIT, TID...)
SDI and HD SDI are broadcast standard television interfaces. Both run on a single co-ax cable, terminated in BNC connectors and in each case, the signal can contain embedded audio data as well as closed caption data, various signal identifiers and even a test pattern. Sadly, this versatile and well proven connection has never made it to the consumer market as it doesn't support the copy protection systems that are part of the HDMI interface.
SDI Technologies was created in 1956.

You might like to take a look at the Tektronix website which has some brief descriptions of analog, SD SDI and HD SDI signals. Their tutorials are based on the use of their own signal monitors of course, but the Harris will have similar functions and of course, the content of the SDI signals is independent of the analyzer. It's probably worth deciding on what information you are trying to gather as it can take a long long time to master all the detail of SDI signals and their relevance to your needs. Typical SDI signals will have auxiliary data imbedded such as audio, closed caption, test lines, idents etc. If you only need to check signal quality with eye patterns, for example, the aux data will only serve to bog you down.
If you want good fuel economy, the SDI is for you. If you want a lot of torque, your best bet is to go for the TDI. The SDI doesnt have a turbo but the TDI does.
SDI stands for serial digital interface. It is a broadcast standard for digital video using a single co-ax cable and BNC connectors with a 75Ohm impedance. The signal carries digital component video, audio and other control data. SDI can also be carried over optical fiber although this is generally only used for long distances in the order of hundreds of metres or yards. Although the connection is the same as that used for composite or analog component signals, the two are not compatible and cannot be interchanged without conversion between analog and digital. SD-SDI runs at 270Mbit or 360Mbit and supports standard definition video signals without compression. It is used as the standard link between equipment in studios and edit suites. HD-SDI uses the same physical interface but runs at 1.48Gbit, five times the data rate of standard definition. It is a component format like the SD equivalent and supports 720p, 1080i at 50Hz and 59.94Hz. Like the SD version, it carries full bandwidth video without compression. The longest physical link for HD-SDI is typically in the order of 125 metres or 400 feet. Longer cables cause signal losses that will cause unreliable data transfer although the precise length is dependent of the type of cable used. Vision mixers or switchers often use inputs that can run as SD or HD. Some have dedicated inputs. Likewise, outputs can be switched between SD and HD in some units while others may have separate outputs offering and HD and SD version of the same content. The exact configuration depends on the manufacturer and the model. SDI is not found outside professional broadcast environments.

From the State's website: California State Disability Insurance (SDI) is a partial wage-replacement insurance plan for California workers. The SDI programs are State-mandated, and funded through employee payroll deductions. SDI provides affordable, short-term benefits to eligible workers. Workers covered by SDI are covered by two programs: Disability Insurance and Paid Family Leave Insurance.
S-video is an analog signal format. It is a development used on domestic video systems to improve the quality of images over the composite video format that was the standard interface between equipment. S-video uses two wires to carry the signal. One is just for the luma signal or "y". the other is for the chroma content, or "c". S-video is also known as a yc signal because of the two components. SDI stands for digital serial interface and is a broadcast standard interface. It is never seen outside commercial studio environments. The interface uses a co-ax cable which carries data at 270Mbit or 1.483Gbit for SD and HD signals respectively. The video element of the signal is a digital representation of component video and is a full quality uncompressed signal. The signal also carries multiple audio channels and other embedded data.
