Once heralded – in our household, at any rate - as the most revolutionary technological development since the toasted sandwich maker, Bluetooth has rather ebbed out of mainstream consumer electronics consciousness.
Admittedly it has its place. But that place predominantly seems to be in the car, with mobile phone headsets, or in the office, with, um, wireless phone headsets. Its range and bandwidth limitations have ultimately stopped it from taking over the living room as much as we might have expected.
Yet Bluetooth is on LG’s new 47LG7000 LCD TV. Coo. So does this mean Bluetooth is finally about to flex some long overdue muscles in the AV marketplace? Um, not really.
For a look at the small print surrounding the 47LG7000’s Bluetooth functionality reveals that it doesn’t deliver such foolish dreams as full video stream delivery from proper AV sources, or even wireless multi-channel audio distribution. Rather it can only be used to receive digital photos from Bluetooth-enabled mobile phones, or to listen to stereo sound from the TV using – you guessed it – a Bluetooth headset.
Still, while we might have used the word ‘only’ back there when talking about what the 47LG7000’s Bluetooth functionality can do for you, let’s not forget that any sort of Bluetooth functionality at all is pretty darned rare in TV circles. And if you do happen to be one of those people content to capture their lives in the relatively low quality of a mobile phone camera, then you might just love the 47LG7000’s Bluetooth efforts to bits.
If all this Bluetooth stuff sounds as much use to you as a chocolate teapot, though, fear not: the 47LG7000 has plenty of other tricks up its 47in sleeves.
Particularly significant among these is TruMotion 100Hz processing. This doubles the set’s scanning rate to 100Hz from PAL’s normal 50Hz, in a bid to reduce motion blur. It also goes a step further than normal 100Hz systems, since it doesn’t just repeat each image frame twice, but rather calculates a new ‘intermediate’ image that fills in the image gap between the two real frames of source data. This should, in theory at least, both reduce smearing interference and make motion onscreen look more fluid.
