Abstract
Abstract A pocket-sized data receiver (10A) which is capable of dislaying a full, 80 column page of data includes a virtual raster display unit (10), and electronic circuitry for receiving data by means of radio transmission or conventional telephone lines, processing the data into a viewable format, storing the data, displaying the data on the raster display unit, and in the case of reception of data over telephone lines, retransmitting of the data to another device over telephone lines. A keyboard (20) connected to a processing unit (18) enables the viewer to enter dialing information, select data for viewing, and control the selection and operation of the data receiver. The data receiver can be held and operated with one hand, and requires only one eye for viewing, thereby leaving the other eye unobstructed.
