Ideal for Windows 2000/XP applications that can use a standard Callback interface, this API supports Microsoft Windows asynchronous I/O format as used by our series of DVB Master cards. This C++ API manages buffering of incoming data and supplies your application with a single data buffer at a time. Each instance of the Callback API class supports a single direction (receive or transmit) stream on the DVB Master cards. The user creates an application callback function to either transmit or receive data from the device. Creation of the stream class generates a thread for data transfer, which then invokes the user's callback functions asynchronously when a full buffer of data is available. Deleting the stream class stops the data transfer and the callback requests. The Callback API comes with DVB TestBed, a sample application that transmits and receives packets of non-video test data so that you can test the operation of the DVB Master cards in your system. DVB TestBed source code illustrates one of the recommended methods of interfacing to the DVB Master cards.

• Asynchronous I/O using callbacks
• Simplified Interface
• C++ interface
• Tested to full 210 Mbit I/O speeds
• Comes with DVB TestBed and source code
