Abstract

This invention resolves the problem of having insufficient display area for viewing long alphanumeric messages in pagers Because of their compact displays, alphanumeric pagers typically permit only partial viewing of long messages. By incorporating a pager into a handheld television, the user will be able to receive and display longer messages.

As shown in Figure 1, the TV Pager features a television screen for viewing messages. The TV Pager combines the functions of a standard handheld television with a pager's ability to intercept and decode data.

   Figure 1 also depicts a situation in which a television scene being viewed on the TV Pager has been interrupted for displaying an incoming message. Note also that in Figure 1, the message has too many characters for viewing on a standard pager display.

   In the TV Pager, the pager electronics become part of the television's electronics. This allows the pager to merge with the television in a manner which supports both pager and television functions. Figure 2 shows a diagram of the TV Pager internal electronics.
