do i need an analog to digital converter box

'The issue isn't about digital versus analog, it's more about channel frequency. It's incorrect to claim that you need a special antenna,' says Hay. 'Antennas made for analog TV signals work just as well for both digital and high definition signals. This means new set top boxes if your TV isn't already able to pick up digital signals.īut that doesn't mean you also need to change your antenna, says Dr Stuart Hay, principal research scientist in electromagnetics with the CSIRO's Information and Communication Technology Centre. In case your TV has SCART inputs (Europe mostly) instead of composite/S-video, you'll also need a SCART adapter, although this may be included with some of the products mentioned above.Like much of the world, Australia is shifting from traditional analog television to digital broadcasting. This would be act like an additional monitor, which may be preferable. If it outputs only DVI, you're in trouble, as you'll need another converter that converts this digital signal to a VGA one.Īlternatively you could get a USB graphics card that outputs TV signals directly, although I can't seem to find one right now. For the computer with DVI output you will hopefully have a graphics card that can output a VGA signal, in which case you merely need a DVI to VGA adapter. You will also need a Mini DisplayPort to VGA adapter to get a VGA signal from your Mac (this also works with the Thunderbolt MBP). These converters are available in a wide price range - generally the more expensive, the better the quality (of the signal). You need to get one that can supply the correct video signal for your TV (PAL/NTSC/SECAM), although most will support all of those.

Therefore you need a converter box (powered via USB or separate power supply) that takes a VGA signal and converts it to composite or S-Video, which can be connected to the TV.

The latest Mac models with either Thunderbolt or Mini DisplayPort can't directly output composite/S-Video (older Macs with micro-DVI could do this when using the right adapter).
