More familiar in the mobile audio world, Bluetooth is appearing in televisions to transmit sound wirelessly, for example to a headset. Other uses are possible and make connected life easier.
Did you know that TCL's most recent televisions are equipped with Bluetooth? This wireless technology has become the standard for mobile sound, in particular to transmit the sound from a smartphone to a headset or speaker. It is being used more and more for all short-distance transmissions, between a Sat-Nav and a smartphone in cars or between a mouse and a laptop computer. Bluetooth was created by Ericsson 20 years ago and has continued to develop; version 5 is scheduled for the end of this year. It has become universal and can be used both at home and on the move. It has a range of around 10 metres, is low-consuming and may transport both data and audio. Connection is almost automatic and its output stability is remarkable. For sound, its quality is more than enough. For the most demanding audiophiles, it may be combined with the aptX codec, but the source and destination appliances must both be compatible. Bluetooth's ability to integrate a whole host of appliances while consuming little electricity has opened up numerous possible uses for it. It is even in connected watches, toothbrushes or fridges.
In televisions too
Recently, it has been installed in TCL televisions for a range of clever uses. The most obvious is sound, and more particularly headsets. In the past, to listen without disturbing other family members you had to use a connected model whose cable was usually far too short. Of course, you could get an extension, but you still had a cabling trailing across the living room which was sure to trip someone up. Headset manufactures also sold radio frequency wireless models which connected to the television's audio socket, but the signal was often subject to interference and crackly. Bluetooth provides an elegant solution to the problem as there are many headsets in this standard available on the market. Their autonomy is extended to nearly 10 hours most often and they can be recharged simply by USB. For TV, around-the-ear headsets provide more comfort. If there are children causing chaos around you, you can use active noise reduction. Simply use the television's own remote control to adjust the volume. You can also connect a Bluetooth wireless speaker for more powerful sound, but you will need to choose a mains-powered living room model for full gain. TCL screens equipped with Bluetooth also provide transmission in both directions. So, you can broadcast something from your smartphone over the television's speakers. This is particularly useful on the X1, the latest model in the ranges, as thanks to its 50W and its 6 front speakers it can faithfully reproduce a piece of music (check on the product) .
Bluetooth isn't limited to audio; you can also connect a wireless input device. So, if you want to control your connect TV or surf the Web, a keyboard and mouse are much more practical than a remote control. Just make sure that they're Bluetooth-compatible to connect them wirelessly to the television. And if you want to play, you can use a handset, which is vital for gaming pleasure.
Bluetooth peripheral connect simply and almost automatically. The first time you want to connect, simply pair up the television and the device for them to recognise each other. They just need to be switched on and near each other to connect each time you want to use them.
