A method for detecting and recovering from call waiting during an interactive two-way remote gaming session. Gaming information is exchanged in real time during a gaming session between two players using a telecommunications link, such as the internet or modem. When a call waiting tone is detected by one of the players, the game is suspended. The incoming call is answered and the other player is notified that the first player is in the process of answering the incoming call. When the incoming call is finished, communications is automatically re-established between the two players, and the game continues at the point just before it was interrupted.

Method and apparatus for detecting and recovering from call waiting

The present invention is a means and method for synchronizing the execution of multiple video game systems in a networked environment with no external synchronization signals required. Video games and most computer display controllers are closed free-running systems. Because most such systems have the means to switch between an interlaced and non-interlaced operation, and because interlaced and non-interlaced modes have a relative timing variation, the timing between two or more such closed free-running systems can be synchronized. This method allows synchronization with an imprecise timing reference. The vertical display timing is the free-running oscillator and the interlaced/non-interlaced mode transition is used as the timing adjustment means. The actual arrival time of data in a communication medium connecting two systems being synchronized is used in relation to an expected arrival time to provide the clock reference.

Method and apparatus for synchronizing the execution of multiple video

A method and apparatus for detecting and recovering from call waiting interference to data communications is disclosed. In a system wherein a first party communicates with a second party via a telecommunications link, the telecommunications link may be disrupted by a third party's attempt to call the first or second party. The present invention detects such a disturbance on the telecommunications line and allows the first or second party to answer the call from the third party. The invention re-establishes communications after the call with the third party is completed.
