HD TO SD PROGRAMME TRANSMISSION LABEL FOR A RAILWAY PROGRAMME SYSTEM

摘要

An Electronic Program Guide (EPG) system is disclosed which accommodates a mix of high definition television (HDTV) and standard definition television (SDTV) EPG display formats. Viewers can toggle from cell to cell of an EPG display using a navigation system such as a remote control highlighting programs of interest. Channels which show a mix of HDTV and SDTV programming have the cells of the grid remain separate for the time period of SDTV programming but join those cells into a single cell when an HDTV program is to be aired.
