  • Patent number: 9686569
    Abstract: The disclosure is related to a method for calibrating an interactive time in a live program, and a system thereof. In the method, a user device is used to receive a live content embedded with a mark from a live program system. A signal processing scheme is performed to identify the mark so as to obtain a marking time. Then an interactive content is received from an interactive serving system. An initiating time of interactive activity is obtained. A time difference between the marking time and the initiating time is counted. The time difference is referred to for calibrating the time of issuing an interactive message when responding to the interactive activity. The responding time, at the system side, is restored to an actual time. Therefore, the method effectively excludes the time error for responding to the interactive activity in the live program due to transmission delay.
