NZS 6606 – Broadcast teletext

Defines the teletext broadcasting system used in New Zealand. Describes: (a) the formation of binary code groups into data-lines for inclusion in the television field-blanking interval; (b) how the control and address information carried on each data-line, together with the special page-header data-lines and the sequence of transmission of the data-lines, allows the data-lines corresponding to the rows of a selected page to be identified; and (c) the method by which the character codes received on the data-lines corresponding to the rows of the selected page are interpreted to give the page display. Additional requirements are given for the transmission of closed caption data by teletext, and an appendix gives details of an enhanced teletext system which may eventually be introduced in New Zealand.
