Virtual channel declarative script binding

摘要

A method consistent with certain implementations involves receiving a triggerable declarative object (TDO) at a digital television receiver device that carries out a programmed script upon execution; the programmed script including a parameter discovery function that determines an operational parameter of the television receiver device and further includes a programmed function; initiating the execution of the TDO in order to initiate execution of the script on a processor of the television receiver device; running the script on the processor of the television receiver device in order to discover the operational parameter and in order to carry out the programmed function; and where the programmed function is conditional upon the discovered operational parameter of the television receiver. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

1. A method, comprising:
receiving a triggerable declarative object (TDO) at a digital television receiver device that carries out a programmed script upon execution; the programmed script including a programmed function and a parameter discovery function that determines an existence of a particular value for an operational parameter of the television receiver device, the operation parameter of the television receiver device corresponding to capabilities of the television receiver device required by the programmed function; initiating the execution of the TDO in order to initiate execution of the script on a processor of the television receiver device; and running the programmed script on the processor of the television receiver device in order to determine the existence of the particular value for the operational parameter and in order to execute the programmed function, wherein execution of the programmed function is conditional upon the determined existence of the particular value for the operational parameter of the television receiver.
