Questions Asked in OTT Interview
Q 1. Explain the differences between adaptive bitrate streaming (ABR) and constant bitrate streaming.
Adaptive Bitrate Streaming (ABR) and Constant Bitrate Streaming (CBR) are two fundamentally different approaches to delivering video over the internet. The key difference lies in how they handle the varying bandwidth conditions that users experience.
Constant Bitrate Streaming (CBR): CBR encodes the video at a fixed bitrate. Think of it like a water pipe delivering water at a consistent flow rate. Regardless of network conditions, the stream will always try to deliver data at that same rate. This means if the network slows down, buffering will occur, and the user might experience interruptions. If the network is fast, the system is using bandwidth unnecessarily.
Adaptive Bitrate Streaming (ABR): ABR is far more sophisticated. It dynamically adjusts the bitrate based on the available bandwidth. Imagine a smart water pipe that adjusts the flow rate based on the size of the pipe and any obstructions. The player constantly monitors the network conditions and selects the highest-quality video stream that the network can handle without buffering. If bandwidth drops, it seamlessly switches to a lower-resolution stream to maintain playback. This results in a smoother viewing experience even with fluctuating network conditions.
In short: CBR is simple but prone to buffering; ABR is more complex but delivers a much better user experience in real-world scenarios.
Q 2. Describe your experience with different video codecs (H.264, H.265, VP9).
My experience with video codecs encompasses the most widely used ones in OTT: H.264, H.265 (HEVC), and VP9. Each offers a different balance between compression efficiency, computational complexity, and licensing costs.
- H.264 (AVC): This is a mature codec, widely supported across devices, and relatively easy to encode/decode. It’s a solid choice, especially for its broad compatibility, but its compression efficiency is less impressive than newer codecs. I’ve used it extensively in legacy systems and for situations where broad device compatibility is paramount.
- H.265 (HEVC): This offers significantly better compression than H.264, meaning you can achieve the same video quality at a lower bitrate. This translates to smaller file sizes and reduced bandwidth consumption, which is crucial for OTT. However, it’s computationally more demanding, requiring more powerful encoding and decoding hardware. I’ve integrated H.265 in several projects where bandwidth optimization was critical, and the target devices had sufficient processing power.
- VP9: Developed by Google, VP9 is a royalty-free codec known for its strong compression capabilities and competitive performance to HEVC. It’s a viable alternative to H.265, particularly for projects where avoiding licensing fees is a priority. I’ve worked with VP9 in projects prioritizing open-source solutions and cost-effectiveness.
The choice of codec depends heavily on factors like the target devices, required quality, available bandwidth, and budget. A proper assessment is crucial for optimal performance and cost efficiency.

I typically avoid RTMP for on-demand unless specific legacy systems require it.
The selection of the optimal protocol depends largely on the application’s requirements (live vs. on-demand) and the target devices and platforms. In many modern OTT systems, DASH is the preferred choice due to its open nature and advanced features.
Q 8. Describe your experience with server-side ad insertion (SSAI).
Server-Side Ad Insertion (SSAI) is a method of inserting advertisements into a video stream on the server before it’s delivered to the client. This contrasts with client-side ad insertion, where the player handles ad insertion, often leading to a less seamless viewing experience. My experience with SSAI encompasses several projects where we integrated it to improve ad performance and user experience. For instance, we worked with a major sports streaming service to implement SSAI using a combination of VAST (Video Ad Serving Template) and VPAID (Video Player-Ad Interface Definition) standards. This allowed us to dynamically insert targeted ads, improving monetization while maintaining a smooth viewing experience. We addressed challenges like latency, ensuring ads load quickly without impacting playback. We also implemented robust error handling and monitoring to identify and address any issues promptly, ensuring the highest quality ad experience for users.
