A display apparatus capable of displaying, by use of an ordinary television set function, character/figure information having a higher display density than standard chemistry character figure information. The apparatus includes a first reducing device for reducing into a pixel a partition having vertical and horizontal lengths respectively twice the vertical and horizontal lengths of a smallest pixel zone associated with a dot pattern signal, character generators and a second reducing device for producing a reduced character pattern associated with character codes in a received signal, and a third reducing device for reducing into a block a partition having vertical and horizontal lengths respectively twice the vertical and horizontal lengths of an attribute data specification block specifying a character/figure display attribute in the signal. The reduced character/figure image signals of the entire screen information obtained through the constituent components above are displayed via a display processing circuit. In a display area appropriately selected by the user, a partial image can be displayed in a specified display density.

High density character and/or figure displaying apparatus

A character multiplex broadcasting receiving apparatus is provided for reducing and displaying a plurality of character figure images including header information and text information. In the invention, to simultaneously display a plurality of character figure images, division signals are formed from a horizontal pulse, a vertical pulse, and a clock pulse (chrominance subcarrier frequency f.sub.sc .times.4) to designate areas on the CRT. Either and animation image (television image) or a character image to display character figure information is designated for each divided picture plane and a plurality of character figure images are simultaneously displayed.

Apparatus for receiving character multiplex broadcasting

A character and graphics display device for displaying character and graphics data which includes a receiving circuit for deriving the character and graphics data from a signal carrying that data encoded therein, a memory for storing the received data, a decoder circuit for decoding the encoded data into suitable form for transfer to a display device, and a display memory for temporarily storing this decoded data, further includes compression circuits for converting the decoded data into a form whereby patterns represented by that data are displayed in compressed size. Pattern and graphics data can thereby be displayed together with other data such as a television picture, or a number of pages of the character and graphics data can be displayed simultaneously.
