Google's Chromecast (Rs 3,999) is available online (unofficially at www.ebay.in, www.amazon.in) and is very easy to use. Simply plug in the device into one of the free HDMI ports on your television and connect its micro USB port to a free USB port on the TV or an alternative source.
Then, switch to that HDMI source (using the TV remote) and follow the set up instructions to connect to the existing Wi-Fi network. Now, install the Chromecast app on your mobile device or PC/laptop and connect to the same wireless network. Run the app and follow the instructions to link the device to the adapter.
Once the setup process is complete, you will be able to 'throw' Full HD videos from YouTube onto your TV screen. If you have subscribed to services like BoxTV, BigFlix, Spuul, NexGTv, you can also stream their shows to your big screen.
