Television Interview Questions and Answers

This article provides a list of questions and answers relevant to television, useful for job interviews in television-related fields and for engineering students during vivas.

Question 1: What is television and how does it work?

Answer: Television (TV) is a telecommunication system designed for transmitting and receiving moving images and sound across a distance. It operates by:

1. Capturing visual and audio signals.
2. Encoding these signals into a transmittable format.
3. Broadcasting or Streaming the signals through radio waves or cables.
4. Decoding and Displaying the signals on a screen, with synchronized audio.

Question 2: What are the main components of a television system?

Answer: The primary components include:

• A display screen (LCD, LED, OLED, or plasma).
• A tuner to receive broadcast signals.
• Audio/Video inputs for connecting external devices (cable boxes, gaming consoles, DVD players).
• Speakers for audio output.
• Internal circuitry for signal processing and control.

Question 3: What are the different types of television display technologies?

Answer: Various display technologies exist, including:

• LCD (Liquid Crystal Display)
• LED (Light Emitting Diode)
• OLED (Organic Light Emitting Diode)
• QLED (Quantum Dot LED)
• Plasma

Each technology has its own advantages and disadvantages regarding image quality, energy efficiency, viewing angles, and cost.

Question 4: Explain the difference between HD (High Definition) and UHD (Ultra High Definition) television.

Answer:

• HD (High Definition) refers to a resolution of either 720p (1280x720 pixels) or 1080p (1920x1080 pixels), offering better image quality than standard definition (SD).
• UHD (Ultra High Definition), also known as 4K, has a resolution of 3840x2160 pixels, providing four times the number of pixels as HD, resulting in sharper and more detailed visuals.

Question 5: What is Smart TV?

Answer: A Smart TV is a television with built-in internet connectivity and interactive features. It allows users to access online content, streaming services, apps, and social media directly on the screen. These TVs often run on operating systems like Android TV, webOS, Tizen, or Roku TV, and can be controlled with remote controls, voice commands, or smartphone apps.

Question 6: How does cable television differ from satellite television?

Answer:

• Cable Television delivers programming via a coaxial cable network operated by a cable provider.
• Satellite Television transmits signals from satellites to a dish installed at the subscriber’s location, offering a wider channel selection and broader coverage.

Question 7: What is the role of television ratings and how are they determined?

Answer: Television ratings measure the popularity and viewership of TV programs. This data helps advertisers and broadcasters make decisions about programming and advertising. Ratings are determined using audience measurement systems like Nielsen ratings, which track the number of viewers watching a specific program, along with demographic information (age, gender, location).

Question 8: What are some recent advancements in television technology?

Answer: Recent advancements include:

• Higher resolution displays like 8K and MicroLED.
• Improved HDR (High Dynamic Range) for better contrast and color reproduction.
• Enhanced Smart TV capabilities with voice assistants and AI-driven features.
• Integration of technologies like VR (Virtual Reality) and AR (Augmented Reality) for immersive viewing.

Question 9: What are some environmental considerations related to television manufacturing and usage?

Answer: Environmental factors include:

• Energy efficiency
• The use of environmentally friendly materials.
• Recycling and disposal of electronic waste (e-waste).
• Reducing carbon emissions from manufacturing, transportation, and energy consumption. Manufacturers are working to create more energy-efficient TVs and encourage responsible recycling.

Question 10: How has streaming technology impacted traditional television broadcasting?

Answer: Streaming technology has revolutionized TV by providing on-demand access to a vast library of content over the internet, bypassing traditional broadcast schedules and cable subscriptions. Streaming services like Netflix, Amazon Prime Video, Hulu, and Disney+ have become popular alternatives, leading to changes in viewing habits and content distribution models.
