发明名称 Receiving device for receiving teletex information, having means for autonomously determining an appropriate character set
摘要 In a receiving device (17) for receiving a television signal (FS2, FS3) which contains character codes (CC) and additional information (CI, NI, UCSI) in VBI lines, having character set storage means (22) for the storage of character codes (CC) and associated reproducible character information (CHI) of a character set and a plurality of character sub-sets, and having VBI read-out means (27) for reading out character codes (CC) and additional information (CI, NI, UCSI) contained in VBI lines of a received television signal (FS2, FS3), and having detection means (20) for the detection of character sub-set information (UCSI) contained in read-out additional information (CI, NI, UCSI), which character sub-set information identifies the character sub-set to be used for the decoding of read-out character codes (CC), and having display signal generating means (21) adapted to generate a display signal (AS) which contains reproducible character information (CHI), taking into account received character sub-set information (UCSI), the character set storage means (22) are now adapted to store character codes (CC) and associated reproducible character information (CHI) of at least two character sets and a plurality of character sub-sets of each character set, and the detection means (20) are, in addition, adapted to detect program source information (NI) or country information (CI) contained in read-out additional information (CI, NI, UCSI) and to supply character set information (CSI) which identifies the character set to be used for the decoding of read-out character codes (CC).
