A software architecture and control protocol that provides seamless playback of multiple clips of media data across a data network. Conventional server-based data network architecture where playback logic resides on the servers does not provide the capability of seamless playback of multiple clips stored in different servers. The present invention allows users to specify a playlist and provides control on the client with the implementation of a "client pull" data transport model. According to the present invention, the playlist is translated into a plurality of frame accurate requests, which are sent from the client to the servers one request at a time. The servers, upon receiving the requests, retrieve the corresponding frames of media data and transmit the media data back to the client. In this way, the present invention allows a user-interface to provide seamless playback of multiple clips that reside on different servers on the client workstation.
