Google has announced two new Chromecasts - one for streaming photos and videos to a TV, and one for streaming music to standard speakers.
The video device is a refresh of the original Chromecast, which has sold more than 20 million units to date. The new version supports faster Wi-Fi and has a new built-in "adaptive antenna system", which allows for higher resolution images and less buffering. The device will also pre-load content it thinks you might want to watch next - such as the next episode in a series - so that streaming is faster.
The second device, Chromecast Audio, connects to speakers and lets you stream audio content from services including Deezer and Tune-In Radio.
Both Chromecast dongles are a circular puck shape, and come in either lemon (yellow), coral (red) or black colours schemes.
Google head of Chromecast for Northern Europe, Dan Saunders said: "We're trying to do for hi-fi what we've done with the TV - turn your hi-fi into a smart hi-fi. If you're used to using apps on your smartphone then using the Chromecast should be easy, as all the processing and control is done on the phone."
Both devices will go on sale next week for £30.
