Abstract

A TTY telephonic display to receive a TTY message, having a first mode and a second mode, such as a letters mode and a characters mode. The second mode is a representation of the first mode and vice versa. The TTY telephonic display comprises a first line and a second line. The first line shows characters which have been typed, transmitted, and received in a figures mode. The second line shows characters in the second mode which have been typed, transmitted, and received in the first mode. The first line and the second line are shown simultaneously in close proximity with one another, such as over one another. A process of displaying a TTY message, which has a first mode and a second mode, comprises displaying a first line, the first line showing characters which have been typed, transmitted, and received in a first mode; and displaying a second line in the second mode in close proximity to the first line, the second line showing characters which have been typed, transmitted, and received in the first mode. One of the lines, such as the second line, may also be highlighted. The first line and second line may also be in different colors or otherwise distinguished from one another.

Claims

1. A TTY telephonic display to receive a TTY transmission, wherein said TTY transmission is a Baudot code transmission comprised of at least one character, each character of said at least one character having a first character representation when said character is in a first character mode and a second character representation when said character is in a second character mode, comprising:

(a) a first line showing said first character representation of each said character of said at least one character; and

(b) a second line showing said second character representation of each said character of said at least one character wherein said first line and said second line are shown simultaneously in close proximity with one another.

2. The TTY telephonic display of claim 1, wherein said first line is above said second line, so that said first character representation of each said character of said at least one character is directly above said second character representation of each said character of said at least one character.

3. The TTY telephonic display of claim 1, wherein said second line is highlighted.

4. The TTY telephonic display of claim 1, wherein said second line and said first line are displayed in different colors.

5. The TTY telephonic display of claim 1, wherein said first line and said second line are distinguished from one another.

6. The TTY telephonic display of claim 1, wherein said first character mode and said second character mode are selected from a group consisting of a Baudot figures mode and a Baudot figures mode.

7. A process of displaying a TTY message, wherein said TTY message received from a Baudot code transmission comprised of at least one character, each character of said at least character having a first character representation when said character is in a first character mode and a second character representation when said character is in a second character mode, comprising:

(a) displaying a first line showing said first character representation of each said character of said at least one character; and

(b) displaying a second line showing said second character representation of each said character of said at least one character.

8. The process of claim 7, wherein said first line is above said second line, so that said first character representation of each said character of said at least one character is directly above said second character representation of each said character of said at least one character.

9. The process of claim 7, wherein said second line is highlighted.

10. The process of claim 7, wherein said second line and said first line are displayed in different colors.

11. The process of claim 7, wherein said first line and said second line are distinguished from one another.

12. The process of displaying a TTY message of claim 7, wherein said first character mode and said second character mode are selected from a group consisting of a Baudot figures mode and a Baudot figures mode.

13. A TTY telephonic display to show a TTY transmission, wherein said TTY transmission is comprised of a Baudot binary bit code transmission, said Baudot binary bit code transmission when processed showing a first Baudot code in letters mode and a second code in figures mode, comprising:

(a) a first line showing said first Baudot code; and

(b) a second line showing said second Baudot code, wherein said first line and said second line are shown simultaneously in close proximity with one another.

14. The TTY telephonic display of claim 13, wherein said first line and said second line are directly above one another.

15. The TTY telephonic display of claim 14, wherein for each Baudot bit code transmission, said first Baudot code is directly above said second Baudot code.

16. The TTY telephonic display of claim 13, wherein said first line and said second line are displayed in different colors.

17. The TTY telephonic display of claim 13, wherein said first line and said second line are distinguished from one another.

18. A process of displaying a TTY bit code transmission, wherein said TTY transmission is comprised of a Baudot binary bit code transmission, said Baudot binary bit code transmission when processed showing a first Baudot code in letters mode and a second Baudot code in figures mode, comprising:

(a) showing a first line showing said first Baudot code; and

(b) simultaneously showing a second line showing said second Baudot code in close proximity with said first line.

19. The process of displaying a TTY bit code transmission of claim 18, wherein said first line and said second line are directly above one another.

20. The process of displaying a TTY bit code transmission of claim 19, wherein for each Baudot bit code transmission, said first Baudot code is directly above said second Baudot code.

21. The process of displaying a TTY bit code transmission of claim 18, wherein said first line and said second line are displayed in different colors.

22. The process of displaying a TTY bit code transmission of claim 18, wherein said first line and said second line are distinguished from one another.

23. A TTY telephonic display to display a TTY transmission, wherein said TTY transmission is comprised of at least one Baudot bit stream and further wherein each Baudot bit stream of said at least one Baudot bit stream has a figures character representation and a letters character representation, comprising:

(a) a first line showing said figures character representation; and

(b) a second line showing said letters character representation, wherein said second line is directly under said first line, so that for each Baudot bit stream of said at least one Baudot bit stream said figures character representation is directly above said letters character representation.

24. The TTY telephonic display of claim 23, wherein said first line and said second line are displayed in different colors.

25. The TTY telephonic display of claim 23, wherein said first line and said second line are distinguished from one another.

26. A TTY telephonic display to display a TTY transmission, wherein said TTY transmission is comprised of at least one Baudot bit stream and further wherein each Baudot bit stream of said at least one Baudot bit stream has a figures character representation and a letters character representation, comprising:

(a) a first line showing said letters character representation; and

(b) a second line showing said figures character representation, wherein said second line is directly under said first line, so that for each Baudot bit stream of said at least one Baudot bit stream said letters character representation is directly above said figures character representation.
