With the rise of streaming services, the way we consume media has drastically changed. Two prominent technologies, Video on Demand (VOD) and Internet Protocol Television (IPTV), have become popular choices for accessing a vast array of content. This article aims to shed light on the fundamental differences between VOD and IPTV, their benefits, and their various applications.

Definitions and Basic Concepts
