VoD - Video on demand

What is VOD?

Video-on-demand (VOD) is a media distribution system that allows viewers to watch content whenever they choose. This means that content is not livestreamed and it does not play on a schedule, as it happens on television. VOD systems typically distribute media using internet connections, so good bandwidth is important to get the best results for viewers. Popular platforms providing VOD services include Netflix, Hulu, Disney, Amazon Prime Video and many others.

VOD platforms face unique challenges due to the diverse range of internet connections and viewing devices used by their audiences. Each user’s connection quality and viewing console vary, making it crucial for these platforms to adapt and deliver consistent, high-quality streams. To tackle this, codecs are continually refined and developed to compress and transmit video more efficiently. The aim is to ensure that every viewer, regardless of their device or connection speed, enjoys the best possible streaming experience.

  3. Pay-Per-View VOD: This model lets users purchase the right to view a specific video once or buy a digital copy for unlimited access. An excellent example is Amazon Prime Video, where you can rent movies for a one-time viewing or purchase them to watch anytime.
  4. Advertising VOD: Designed for advertisers, this model involves placing ads on popular subscription platforms. Advertisers pay to have their ads shown to targeted audiences during various shows.
