A High-Level Programming Language for Multimedia Streaming
Liquidsoap: a High-Level Programming Language for Multimedia Streaming David Baelde1, Romain Beauxis2, and Samuel Mimram3 1 University of Minnesota, USA 2 Department of Mathematics, Tulane University, USA 3 CEA LIST – LMeASI, France Abstract. Generating multimedia streams, such as in a netradio, is a task which is complex and difficult to adapt to every users’ needs. We introduce a novel approach in order to achieve it, based on a dedi- cated high-level functional programming language, called Liquidsoap, for generating, manipulating and broadcasting multimedia streams. Unlike traditional approaches, which are based on configuration files or static graphical interfaces, it also allows the user to build complex and highly customized systems. This language is based on a model for streams and contains operators and constructions, which make it adapted to the gen- eration of streams. The interpreter of the language also ensures many properties concerning the good execution of the stream generation. The widespread adoption of broadband internet in the last decades has changed a lot our way of producing and consuming information. Classical devices from the analog era, such as television or radio broadcasting devices have been rapidly adapted to the digital world in order to benefit from the new technologies available. While analog devices were mostly based on hardware implementations, their digital counterparts often consist in software implementations, which po- tentially offers much more flexibility and modularity in their design. However, there is still much progress to be done to unleash this potential in many ar- eas where software implementations remain pretty much as hard-wired as their digital counterparts. -
