Abstract: Aspects of protocol switching and cross-wiring to enable inter-network connectivity are described. For example, a transporter system including a transporter server and a transporter client can securely connect applications to resources in differing networked environments (e.g., clouds and/or data centers). The transporter client may establish data channels as secure socket layer (SSL) connections (e.g., Secure Websockets (WSS)) between a resource in one networked environment and a transporter server that is in communication via a proxy channel with an initiator device in another networked environment. Upon completing the build of a data path between the initiator device and the resource, the handling protocol of the data channels that are established as SSL connections can be modified to a basic socket-level channel (e.g., transmission control protocol, user datagram protocol, etc.) to permit socket-level data stream communications without restrictions.

Abstract: An authoring tool has a graphical user interface enabling interactive authoring of a multimedia presentation including temporal and nontemporal media. The graphical user interface enables specification of the temporal and spatial relationships among the media and playback of the presentation with the specified temporal and spatial relationships. The spatial and temporal relationships among the media may be changed independently of each other. The presentation may be viewed interactively under the control of the author during the authoring process without encoding the audio and video data into a streaming media data file for combination with the other media, simulating behavior of a browser that would receive a streaming media data file. The multimedia presentation may include elements that initiate playback of the presentation from a specified point in time. After authoring of the presentation is completed, the authoring tool assists in encoding and transferring the presentation for distribution.
