Abstract

A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes generating an application parameter table which includes information about at least one of applications, wherein the application parameter table includes a first identifier and a second identifier, wherein the first identifier identifies a interactive programming segment which application parameter table pertains to, and wherein the second identifier identifies an application within the scope of application parameter table; generating an activation message file that indicates at least one of activation times of the applications, wherein the activation message file includes a third identifier and activation messages, wherein the third identifier matches the first identifier of application parameter table which contains the applications, wherein the activation message includes a fourth identifier and a start time information, wherein the fourth identifier matches the second identifier of the application in the application parameter table, and wherein the start time information indicates the start time for an event targeted to the application relative to segment time; generating a multi-part message with the application parameter table as the first part and the activation message file as the second part; and transmitting the multi-part message to receiver via HTTP.

Claims
