View Full Version : Coaxial Resolution? btwilli1 07-13-07, 01:38 PM I've been searching google with no luck. What kind of resolution would you get through coaxial input? Suppose I hook up my 8300 STB through coaxial would it be 480i? Does it work like OTA where it will display a HD image (720/1080i)? Parnelli66 07-13-07, 02:34 PM The coax input (if it is a digital one) can receive the signal from an over the air antenna, but I dont think from a set top box. Use the following connections (in order of best pic quality) HDMI/DVI; Component, S-Video I think If you use regular coax the best you will get is standard def 480i btwilli1 07-13-07, 03:15 PM If you connect an external antenna through the coaxial you can get 1080i OTA signal. You don't think STB could output 1080i through the coaxial either? btwilli1 07-13-07, 03:18 PM I found my answer, but it still doesn't explain how you can get a 1080i OTA through an external antenna connected through coax input? Here the link to a chart describing the abilities of each input http://www.pureav.com/video/sourcetosense/ fooit 07-13-07, 03:23 PM I've been searching google with no luck.

AFAIK, 8300 STB has RF-output to hook up older TV with RF-input only. You will be able to see all the channels including digital ones downconverted to 480i. btwilli1 07-13-07, 03:38 PM Thanks for the info guys! dssturbo1 07-13-07, 10:13 PM I found my answer, but it still doesn't explain how you can get a 1080i OTA through an external antenna connected through coax input? Here the link to a chart describing the abilities of each input http://www.pureav.com/video/sourcetosense/ simple put your local ota station uses 8VSB compression and sends the transmission out then your antenna receives it and sends it over RG6 coax to your set top box which has an internal atsc tuner/decoder that decompresses the transmission and then sends out hd signals over hdmi/dvi/component. your cable company uses QAM compression and sends it over coax to a set top box or tv with an internal QAM tuner then it outputs it over the hdmi/dvi/component cables or downrez it to SD over RF coax, svideo composite. goggle these terms and read on it for alot better explanations. 8vsb mpeg 2 or 4 atsc ntsc QAM i could easily be way wrong on these, so best to google, read and get the correct info. |
