Hi, Meron po nakapagsabi sakin na madali lang daw i modify yung PCI TV Tuner to stand alone TV Tuner. Marami na din kasing 2nd hand tv tuner ngayun na 500petot lang, baka sakaling meron pong naliligaw na schematic dyan

. Tnx

Parang mahirap ito ksi ang PCI TV tuner eh wla nmang composite TV out. Kailangan mo ng computer to process the image from the tuner then convert it to a signal with which the computer sends to the monitor thru video accelerator card.

cheapest alternative na nga yung tv tuner for monitor, no need pa ipowerup ang pc, kahit lcd monitor lang.

check mo datasheet nung TV Tuner na nasa yerong lalagyan. kapag ang output noon ay Video IF at FM PLL merong demodulator, makakakuha ka ng idea sa I2C specification sheet.

meron ding mga Tuner na ang output ay CVBS na, 'yun lang hindi mo magagamit sa LCD monitor. from CVBS to VGA/RGB/YPbPr, that's a different story.

I can't share every detail but this is doable.

basta check mo lahat ng datasheet ng IC, kung ASIC, wala ka nang magagawa. at one part diyan ginawa 'yung demodulation (pwede ring wala) at pinasok sa ADC.

sir noth1ng, gumawa na ko nyan dati sony tuner ang ginamit ko kasama na yung IF block

with additional potentiometer and 32 volts, and 9 volts supply

and audio video outputs,

ok na ok ang dating

ginawa ko ulit sa lumang VHS player na my built in IF block

hmm

tagal na pala neto nabuhay uli dahil sa projector

Oo, nakalimutan ko na nga rin to kasi bumili na ako nung TV Box sa CDR King. Pero me nakapagsabi sakin na pwede nga daw gawin talaga. Ni-confirm ko lang po dito kung meron na nakagawa.

merong Philips demodulator na CVBS plus Audio ang output. 'yung TV Box ko (KWorld) 'yun ang IC pero 'yung PCI TV Tuner ko dati, 'di ko na-check kung ano 'yung demodulator (nawala na).

typical, I2C ang control sa paglipat ng channel doon sa mismong tuner na box.
