Nowadays, it's common that each user has different capabilities and each media content has different requirements. So, in this project will be studied and implement a first approach how to adapt media content stored in repositories to users capabilities. Different kinds of video content will be studied, and how their requirements can be changed with a good subjective quality for the user. Depending on the kind of content, different types of changes could be done in order to decrease the video requirements; for example, in some cases, a change on the resolution will be better in terms of subjective quality than a decrease into the frame rate frequency and vice-versa. As a result, it will be designed a first approach of a system able to: · determine user capabilities in terms of bandwidth, resolution, computer power ¿ · know the kind of content to be streamed · find the best way to adapt the video depending to its content according to each user capabilities · provide a content preview that requires less user capabilities and enables the user a quick look of every content in a simpler terminal before to use the original one
