INTERACTIVE SERVICES

摘要

A method and a device (1) are provided for interacting with events in a broadcast audio stream. Patterns in the audio stream are compared to a stored signature (29) associated with the events and a function is executed in response to a successful match indicating the detection of an event. A viewer can participate in a broadcast quiz show using the device (1). Questions are provided in a graphical representation on the display (15) of the device (1) and the user can input answers to the questions. The event may be a buzzer in the audio stream of the broadcast quiz show, indicating that the time for responding to a question has expired and the function executed in response to detecting the signature of the buzzer may include terminating a time period in which the user can answer the questions using the device. The method of the invention also includes connecting to a server (3) for downloading data and instructions for participating in the interactive services and uploading user inputs for receiving rewards and prizes.
