Abstract
Techniques and configurations for streaming metadata between devices are disclosed herein. In one example embodiment, streaming textual data, for example subtitles or closed caption data, are provided from a consumer television or set top box (STB) platform to a tablet computer platform. XMPP and BOSH are used as infrastructural components to help establish the client/server connection between the platforms. These components also maintain this connection and support real-time communications and transfer of data between the platforms. In an example embodiment, an application on the primary platform has a string of metadata which is communicated to a client application on a second platform. For example, client application may be a smart phone app in the form of an HTML5 app running on browser. The system may stream and control bi-directionally. In this architecture an XMPP-implementing JavaScript library allows XMPP client interaction through an XML stanza.
