The UPlayer Hypervideo format uses the file extension SCE. This format was developed by a company called LongLiveVideo. It is still at the early stages of development and has seen little or no adoption on the Internet. This format has been developed to be used for streaming content over the Internet.

While there are other more popular formats for all kinds of online streaming video, this format implements a different layer of information with the video. The concept behind Hypervideo is about linking different parts of the video to other videos like hyperlinks within a text. Just like one can click on a word on the body of a text and go to another page, the Hypervideo format enables the user to click on various parts of the video to visit different videos. This can thus serve many different purposes. It can be very effective in creating interactive video presentations and it can also help in the field of education. Other than that, it can create multi-ended videos where the user can choose an ending.
