Abstract
Enhanced television content is processed and displayed by the execution of computer-readable instructions formatted in a binary interchange format (BIF) of an enhanced television BIF (EBIF) application via user agent at a client by interpreting the computer-readable instructions directly and without additional compilation. A key identifier may be used by the EBIF application to identify a content programming engine to locate and retrieve programmable content to be displayed at the client.
