extremely good discussion .. may i, add, in all humility, and with deference to the experts here : 1. cable tv is still co-axial .. not digital 2. there is no digital speed on the co-axial for tv 3. the analogue signal is the carrier 4. there are 99+ channels on ONE co-axial 5. frequencies of the channels are different 6. a 'tuner' is used to get the channel of one's choice 7. there is audio AND 'video' data 8. pic res is 352 x 288 pixels (ugh !) 9. tv delivers (so do webcams, even digital ones .. where the pic IS digitally recorded and can be played back in DVD format too) 10. non-digital in NOT analogue .. its just non-digital .. like negatives of photos, older audio casettes/wax/vinyl records, video .. err .. movie films, video casettes, etc .. even human sound is not 'analogue' .. electronically that is ! .. it just NOT digital ..pi I (the cable based internet is usually rj45 wan at present .. co-axial cable modems are just not being implemented in calcutta yet !) -- To unsubscribe, send mail to [EMAIL PROTECTED] with the body "unsubscribe ilug-cal" and an empty subject line.
