Transactional Video on Demand (TVOD) is a business model in the media and entertainment industry that allows users to rent or purchase individual video content on a pay-per-view basis. It is a digital distribution method where users have the option to access specific video content, such as movies, TV shows, or other forms of digital media, for a specified fee. 

In TVOD, users typically have the flexibility to choose the content they want to watch and pay for it separately. The payment can be in the form of a one-time rental fee or a purchase price. Once the payment is made, users are granted access to the content for a limited period (in the case of rentals) or indefinitely (in the case of purchases). 

TVOD platforms or services enable users to access a wide range of video content on-demand, giving them the freedom to watch what they want, when they want. This model is often used for recently released movies, premium or exclusive content, or niche content that may not be available through other distribution channels. 

TVOD differs from subscription-based models like Subscription Video on Demand (SVOD), where users pay a recurring fee to access a library of content. With TVOD, users have more control over their viewing choices and only pay for the specific content they wish to consume. 

TVOD services can be accessed through various platforms, including streaming devices, smart TVs, mobile apps, or web browsers. Examples of TVOD platforms include Apple iTunes, Google Play Movies & TV, Amazon Video, and Vudu. 

Overall, the TVOD model provides users with the flexibility to rent or purchase individual video content, allowing them to choose and pay for specific movies, TV shows, or other digital media on a per-view basis.
