Abstract
The present invention describes and claims a new system and technique or method for decoupling the interpretation of broadcast content information from the display of this information. The information may exist in any of the available types, such as audio, video, or data. In addition, the information may be received in any form, such as streaming or non-streaming, combinations of the two, or even parts thereof. The decoupling and encapsulating of the broadcast content information is accomplished using a content proxy. All content information in the content proxy is accessed via an Application Program Interface. The content proxy employs a hierarchical Document Object Model (DOM) that contains Program and System Information Protocol (“PSIP”) data, that has been converted to an eXtendible Markup Language format using a conversion algorithm, broadcast content data, as well as content data or information about all of the hardware, software, and appliances connected within the networked environment. The proxy concept is applicable to the design and implementation of a Digital TV broadcast rendering device within a Digital TV Application Software Environment framework.
