I’ve recently come across the term RIA. Can someone describe to me what RIA means and how it relates to technology? What are its features and advantages? Also, briefly explain the history of RIA to me.

SDI: Definition and Meaning
SDI or Serial Digital Interface refers to the standard format through which delivery of any digital video takes place using coaxial cable. SDI supports data speed up to 3 Gbps. You need a standard 75-ohm cable to let SDI operate on your home TV installations.
It is included in types of common digital video interfaces like SDI, HD- 12G-SDI, SDI, 3G-SDI, and 6G-SDI—widely in use in the broadcast and TV industry.
SDI: Needs and Purposes
The primary function of SDI (Serial Digital Interface) is to transmit uncompressed and unencrypted digital video signals in TV studios. But it is also used for various other broadcasting purposes including some technical operations as well.
How much speed does SDI offer?
SDI can offer speed up to 3Gbps but usually, it offers to speed up to 270 Mbps. However, some of the latest SDI (released after 2015) can give you speed up to 12-GBPS.
Can I use my PC without SDI?
Yes. You can. You need SDI only when you want to watch TV.
Why is SDI used for?
SDI is used to transmit signals in an uncompressed and self-synchronised format. It helps in transmitting the signal from the transmitter to the receiver in the least possible time.
The standard it follows helps in utilizing the data words, which are 10 bits in length. SDI signals can have 1–4 independent digital audio signals along with video signals. Right now, SMPT 2110 is the most acceptable standard format for SDI on IP networks.
History of SDI
The SDI video standard got its existence for the first time in 1989 when SMPTE (Society of Motion Picture and Television Engineers) invented it to enhance their audio-visual quality.
Thereafter, its quality kept on getting better and better. 1998 is crucial in this regard as High Definition SDI was launched for the first time in history in the same year.
What is the difference between HDMI and SDI?
Technically, both HDMI and SDI are used for transmitting uncompressed audio and video signals. However, there’s a slight difference between these two terms.
HDMI is famous for connecting Blue-ray DVD players and other audio-video streaming devices like video game consoles, Xbox, and others. It offers high-quality resolution up to 10k to 120 hz. Most HDMI cables can support up to 40 feet. It costs much lower than SDI.
On the other hand, SDI is used mainly by broadcast professionals and sound engineers. It is quite expensive. An SDI cable can support up to 96 feet. It has been in use since the late 90s.
What are SDI standards?
SDI standards refer to the various versions of SDI available in the market.
SD-SDI (SMPTE 259M), ED-SDI (SMPTE 344M), HD-SDI (SMPTE 292M), Dual Link HD-SDI (SMPTE 372M), and 12G-SDI (SMPTE ST-2082) among others are some of SDI popular standards.See less

The short form of Rich Internet Application is known as RIA. It is in-built within the framework of a Web browser. The RIA eliminates software installation on the client-side to work.
Thus, the RIA was created to deliver the same features and functions normally associated with Desktop applications but much faster, versatile and safe.
Most of the RIAs run their client portions within a special isolated area of the client desktop which is called a Sandbox. The sandbox protects the client’s file and operating system.
Thus it also provides safety to the application server of the client. It may be mentioned here that there are some RIAs that work properly with one or more specific browsers thus it is not for general purposes.
Features/characteristics of RIA:
The RIA has several features. The main features are:
Web-based applications similar to features/characteristics of graphical desktop applications.
RIAs are faster and more engaging.
RIAs offer better visual experience.
RIAs are more interactive than traditional browser applications that use only HTML and HTTP.
It splits the processing across the Internet/network divide by locating the user interface.
The RIA is the client engine that intermediates between the user and the application server.
Main Features of RIA:
The RIAs has several features including:
RIAs Interacts Directly:
RIAs allow a wider range of controls facilitating greater efficiency. To exemplify this point, users can interact directly with page elements including a map, chart, graph, and images through editing or drag-and-drop tools.
It Keeps on Updating the Page Partially:
This is one of the most useful features of the RIA. It incorporates such benefits like real-time streaming, high-performance client-side virtual machines, and local caching mechanisms. Subsequently, the wait times are reduced, increasing the responsiveness.
Better feedback system:
Because of their ability to change parts of pages without reloading, RIAs can provide the user with fast and accurate feedback, real-time confirmation of actions and choices, and informative and detailed error messages.
Benefit of Offline use:
It can work offline when connectivity is unavailable.
What are the advantages and disadvantages of RIAs?
RIAs perform better than traditional apps. This is a major advantage. However, there are certain disadvantages of RIAs also. Following are major advantages and disadvantages of this system:
The Advantages of RIA:
Mobile Access to Information
Tracking of Batch and Item Level Made Easier
Master Item Synchronization
Better Data Visualization
The Disadvantages of RIA:
It has some disadvantages which are following:
Briefly history of RIA:
RIA, a term coined in 2002, took several years to progress, mature and finally shape. The first RIA research appeared in 2004 and from 2007, there had been major research on it which further increased after 2009.
For all practical purposes, the RIA was introduced in 2002 by Macromedia (which later became Adobe Flash). This term was given in a white paper of March 2002 by Macromedia.
The RIAs allow the client system to handle local activities, calculations, and reformatting jobs thus reducing the amount and frequency of client-server traffic.See less
