ABSTRACT:
A method and apparatus for transmitting video over telephone lines is provided. FM data is produced representative of a video picture to be transmitted and synchronization data concerning the transmitted picture is also produced. The FM data and the synchronization data are transmitted via telephone lines to a receiver. A pair of memories is provided in the receiver. The receiver uses the synchronization data to coordinate the storage and display of the received pictures. One memory displays the picture while the other memory is being loaded. The memories are toggled so that the memory from which the previously stored data is displayed becomes the memory being loaded and the memory being loaded becomes the memory from which previously stored data is displayed. Alternatively, one memory is a load memory while the other memory is a display memory. After the incoming picture is stored in the load memory, it is transferred to the display memory.
