METHOD AND APPARATUS FOR STREAMING METADATA BETWEEN DEVICES USING JAVASCRIPT AND HTML5

摘要

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.
