Odisha CHSE +2 Vocational Audio Video Technique study guide
Odisha CHSE +2 Vocational Audio Video Technique · Work through your exam, one topic at a time.
The Odisha CHSE +2 Vocational Audio Video Technique (AVT) is a vocational subject at the higher secondary stage under the Council of Higher Secondary Education, Odisha. It gives students a working grounding in sound and picture production rather than a purely academic science or arts course, and it suits learners who intend to move into entry-level studio, cable, event-video, sound-reinforcement or media-adjacent work, or into a media diploma or degree afterwards. The Odisha CHSE +2 Vocational Audio Video Technique study guide has 13 sections and about 4,929 words.
01Fundamentals of Sound
Sound is a longitudinal pressure wave: particles oscillate along the direction of propagation, so sound needs a medium and cannot cross a vacuum. This domain tests whether you can link the physical properties of a wave to what a listener perceives, and whether you can handle the decibel and the wave equation numerically instead of by guesswork.
405 words, about 2 min02Acoustics and Hearing
Acoustics and Hearing moves from one wave to a room full of them, and then to the ear-brain system that interprets them. The exam expects you to calculate reverberation, explain why rooms colour sound, and name the psychoacoustic effects that guide microphone and monitor placement.
396 words, about 2 min03Audio Recording Equipment
Audio Recording Equipment covers the chain from transducer to storage and the numbers that keep it clean: levels, impedance, sampling, bit depth and file size. The exam tests practical gain-staging and whether you can justify a sample rate or bit depth rather than recite it.
381 words, about 2 min04Microphones and Mixing
This domain joins the two halves of every audio session: choosing and placing microphones, then combining their signals on a mixer. The exam asks you to justify a microphone choice by transducer, polar pattern and placement, and to explain console signal flow without confusing fader, bus and insert.
399 words, about 2 min05Fundamentals of Video
Fundamentals of Video covers how a moving image is captured, scanned, stored and described numerically. The exam checks frame-rate and shutter arithmetic, aspect ratio and resolution literacy, and understanding of what interlacing and chroma subsampling actually discard.
394 words, about 2 min06Television Signals and Colour Systems
Television Signals and Colour Systems explains how colour became compatible with black-and-white receivers and how digital television now represents colour. Expect questions on luma weighting, the three composite systems, and which artefacts belong to composite decoding.
362 words, about 2 min07Camera Operation
Camera Operation tests whether you can actually run a camera: set exposure, balance colour, focus, and move the camera for a reason. Questions come as practical scenarios, so answer with a decision and the setting that achieves it.
389 words, about 2 min08Composition and Lighting
Composition and Lighting is where technical craft meets meaning. The exam wants named shot sizes and angles, the continuity rules that keep an edit legible, and three-point lighting with controllable ratios rather than vague advice to "make it look good".
367 words, about 2 min09Scripting, Planning and Pre-production
Scripting, Planning and Pre-production examines whether you can turn an idea into documents a crew can shoot from. Marks go to format knowledge and to realistic planning arithmetic, not to a synopsis alone.
333 words, about 2 min10Audio and Video Editing and Post-production
Audio and Video Editing and Post-production tests whether you can assemble a sequence deliberately and finish it technically. Expect questions on edit types, timecode and frame arithmetic, track discipline in audio, and the difference between correction and grading.
363 words, about 2 min11Studio and Field Production Practice
Studio and Field Production Practice asks how a real shoot is run: who says what, which light means what, and how a crew moves from location to edit safely and with intact material. Answers should name roles and hardware rather than describe a vague "team effort".
404 words, about 2 min12Multimedia, Digital Media and Emerging Broadcast Technologies
This domain checks that you can name today's delivery chain and use its units correctly: codecs versus containers, streaming protocols versus file transfer, and resolution versus dynamic range. Many candidates lose marks by using "HD" and "high quality" as if they were measurements.
378 words, about 2 min13Practical Work, Project and Viva Voce
The practical component carries marks for demonstrable skill and for explaining it. The exam and viva test whether you can set up and operate equipment safely, submit a documented project, and defend your creative and technical choices in plain language.
