The data receiving apparatus comprises a display device, a data memory, a control information memory for storing therein display control information representative of an order in which transmitted display data is displayed, and a controller. The controller is responsive to display switching information transmitted from the data transmitting apparatus to read the display control information stored in the control information memory, sequentially reads the display data from the data memory in accordance with the display order represented by the read-out display control information and supplies the same to the display device. The display data includes previously stored display data and current display data, and the display control information includes transmission code data indicating whether the display data is advance transmission data or real time transmission data.
