The present invention relates to an electronic device (100) for remote control of a set-top box (STB) for a television set (TV) to update the mapping between: - a plurality of predetermined identification numbers (NUM1, NUM2, NUM3) associated with television channels (CH1, CH2, CH3), and - a plurality of identifiers (ID1, ID2, ID3) each associated with a channel on which one of said channels (CH1, CH2, CH3) is broadcast, said television channels (CH1, CH2, CH3) being broadcast by a broadcast operator (D) in order to be received and viewed on said television set (TV) via a set-top box (STB), said device (100), which is external to said television set (TV) and to said box (STB), including, in particular, a processor (21) configured to interact with second communication means (12) in order to download, from a remote central server (S) via the mobile telephone network (N_CELL) and depending on said television channels (CH1, CH2, CH3) accessible on said television set (TV), an electronic program guide computer file (F_EPG) comprising an up-to-date map of identifiers (M_ID) mapping between said identifiers (ID1, ID2, ID3) and each of said television channels (CH1, CH2, CH3) accessible on said television set in order to associate each of said identifiers (ID1, ID2, ID3) with an identification number (NUM1, NUM2, NUM3). |
