Abstract: Methods and systems for transmitting and receiving data, such as, for example, entertainment data, are presented. In one example, a data file is segmented into a plurality of data modules. A header is generated for each of the data modules, with the header including a module identifier for the data module associated with the header. An indication of a number of the plurality of data modules associated with the data file, and at least one multicast address from which the plurality of modules may be received via a multicast transmission, are generated and transmitted. The data modules with their associated headers are transmitted over a communication network in the multicast transmission.

Abstract: Methods and systems of playing multiple media streams in a single-player environment are presented. In an example, creation of a live media player associated with a first output of a media machine and creation of a non-live media player associated with a second output of the media machine are requested. The live media player and the non-live media player are presented to a resource manager of the media machine with a shared live property for assignment of separate media tuners. In response to the assignment, live playing of a first media stream using the live media player and live playing of a second media stream using the non-live media player are initiated.
