1187511 2011-03-19 15:18:00 Hi,

I just want to know whether a same frequency can be shared by 2 different TV channels?
If it can be shared, can both the channels be telecasted at the same time?????


Thank You.

1187513 2011-03-19 23:02:00 Maybe - one vertically polarised, the other horizontal. Peter H (220)
1187514 2011-03-20 02:39:00 Are you talking digital TV, such as Freeview ?

If so, the answer appears to be yes - see en.wikipedia.org

"...Rather than carrying the data on a single radio frequency (RF) carrier, OFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulate a set of closely spaced adjacent carrier frequencies. In the case of DVB-T, there are two choices for the number of carriers known as 2K-mode or 8K-mode. These are actually 1,705 or 6,817 carriers that are approximately 4 kHz or 1 kHz apart...."
