Abstract: The present invention teaches new solutions based on an alternative approach to controlling client behavior in adaptive streaming applications, namely, server managed adaptive streaming. in this approach, the client makes requests for streaming content and provides extra information about its behaviors, and the server verifies the information to determine if the requests can be granted. This way, even if the client is not trusted, its behaviors can be properly and effectively controlled. Moreover, all of the solutions resulting from adopting this server managed adaptive streaming approach fit into the MPEG/3GPP standards of Dynamic Adaptive Streaming over HTTP (DASH).

The biometric-based music recommendations take into account the changing music preferences of users from time to time as their biometrics change, such as due to users wellness states, being in different moods, engagement in different activities, and/or entering different environments. The schemes herein are implemented on user devices equipped or coupled to wearable devices capable of collecting biometrics data from users, such as heart rate, perspiration, and skin temperature data. The biometrics data of a user are collected and then processed into biometrics information. The biometrics information is then classified into a current wellness state of the user. A music recommendation is then provided to the user according to the biometrics information and the current wellness state of the user.
