ABSTRACT:
To reduce the time required to access serially transmitted teletext data, such data is often stored in memory. The present invention reduces the otherwise required memory size by storing the characters in proportional form and/or with duplicated characters not stored a plurality of times but stored with information on the number of times a character is duplicated.
