Indian AV Specialist Certification Course

The AV Industry participated in CAVS first two course editions in Mumbai. Third CAVS course is scheduled to be held in Ahmedabad in March 2023. PALM AV-ICN magazine interviewed the promoter and founder of CAVS in India, Anil Chopra to understand the credibility, validity and legitimacy of AV-ICN's CAVS certification.

The team behind CAVS - Smita Rai, Deputy Project Director, Hyve India; Arif Patil, Principal Consultant, Eyte Technologies; Abdul Waheed, Managing Director, Eyte Technologies; Harshen Naidu, Director, Rhino Engineers; Narendra Naidu, Chairman & Managing Director, Rhino Engineers; Anil Chopra, Founder, CAVS; Deep Patel, Rhino Engineers

Is the CAVS certification a clone of InfoComm's CTS Education programme?

CAVS is not a clone. It is independent and a standalone initiative by the AV-ICN platform.

What comprises the AV-ICN platform?

AV-ICN is an independent, neutral AV technology expo. The platform comprises a full fledged three-day conference on AV industry attracting the leading intelligensia of the AV industry. AV-ICN platform also includes a magazine dedicated to AV technology. AV-ICN also publishes a newsletter every fortnight circulating digitally to the entire database of the AV industry to 62,000 recipients including the pro audio industry. Apart from the expo and magazine and newsletter, the AV-ICN website is a cornerstone which is updated daily with news on the AV industry. The CAVS is an important edition to the AV-ICN platform. AV-ICN also actively communicates with the AV industry on FB, Instagram and Twitter. AV-ICN is a comprehensive platform evidently dedicated to AV technology, AV professionals and AV solutions for India where next gen AV innovation is being absorbed and used at par with global trends.

Types of Connectors

Used in a multitude of applications, from home theatres to pro audio mixing boards, audio connectors are essential to the concept of sound


The vital differences between interlaced scanning and progressive scanning is what redefines the modern era of video signalling


A brief comparative table offers a glimpse into the key differences between the parameters for conventional AV and AV-over-IP

Viewer Placement

The viewing cone, which informs the viewer's viewing angle, is central to determining an acceptable visual performance

Aspect Ratio & Resolution

The aspect ratio of an image defines the relationship of the image height with the image width in order to enhance the viewer's viewing experience

Inverse Square Law

The Inverse Square Law, the key to understanding how brightness works, suggests that the more the viewer moves away from the source of light, the light at the viewing point decreases and the vice versa

Network Standards

To enable the swap of information and data back and forth on the internet, the computer's software is hardwired to follow a list of built-in network standards


A universal language for computer networking, the OSI model splits up the communication system into seven separate layers, stacked onto one another

IP Protocol

While the IPv4 isn't designed to handle the sheer number of IP addresses, the IPv6 supports an infinite number of IP addresses

Expo, magazine, newsletter, website, social media is the norm. However, offering education with certification requires a certain level of authorization. How do you justify CAVS certification course?

AV-ICN platform possesses a certain level of knowledge quotient of AV technology. Professionals in AV technology have been involved in preparing the curriculum, the course faculty is also credible and includes active professionals from the industry. However, I feel that this is a given for any education course, providing certification is totally justified as the AV-ICN platform is clearly deeply involved with AV technology and possesses the required knowledge quotient to deliver a three-day course with an examination and I feel justified in issuing a certificate

How legitimate is the curriculum and can you give us a brief outline of the curriculum?

Naturally, the curriculum is 100% legitimate as the cost includes technical content. The cost is a matter of choice. The technology remains the same for every cost from every institution. As I said, hardcore professionals have prepared the curriculum. CAVS curriculum is infact the best researched content applicable as a primer for AV specialists imparting important information on key information specially for AV integration networking and communication.

Can you elaborate on the curriculum fulfilling the AV specialist classification?

Right! Point specific first three sections are naturally - 1. Audio 2. Video 3. IT - Information Technology. Each section explains the basic structure of: a) Standards b) Protocol c) Connectors d) Cables e) Best practices in networking, integration and communication.

Over three days in the CAVS classroom, AV is introduced with a primer on subjects like acoustics, signal-to-noise ratio, frequency, impedance in audio and features of products like headphones, amplifiers and microphones are explained.

In video, students are introduced to concepts of resolution, aspect ratio, screen size, display technology and inverse square law, and products on digital signage, conferencing, lighting control and integration of spaces like auditoria.

In the IT section, different types of networks, types of signals, lighting control concepts and other concepts relating to AV integration are introduced.

At the end of three days and the examination, the student is far ahead in understanding AV and entering the AV industry as an employee has the credibility to be considered an AV specialist.

How will the creation of an AV specialist course impact the AV industry in India?

The Certified AV Specialist course is an absolute necessity. I want to reiterate, it was absolutely necessary to create an Indian AV specialist course. I want to emphasize that CAVS is an imperative catalyst to develop and attract talent and human resource to the AV industry as a career.

Anyone with CAVS certification will stand apart from the normal technician. Clearly, integration and networking projects executed by CAVS teams are ensured to adopt best practices and proper standards and protocols.

CAVS is affordable to the point where the actual course is below cost at this point. Education is the key factor in CAVS initiative. AV-ICN platform is committed to impart knowledge, information and education on AV technology. CAVS is a very meaningful contribution where the entire effort in creating a purposeful curriculum and then subsidizing the classroom and course attracts talented human resource to AV industry.
