Chromecast is a video stick introduced by Google in 2013. It can display the contents of other devices on TV screens and upgrade TVs to Internet TVs. It can be considered a variant of a set-top box. Today, we finally have to usher in its second generation.

According to 9to5Google reports, the second generation of Chromecast hardware may appear on the September 29th Google conference (and there will be two Nexus phones). From the leaked picture, it looks very different from the first generation and looks like a headset with a USB interface.


Functionally, the second generation may be able to push the stream of information to the television (such as social media information), there will be better WiFi (may be 802.11ac), and Fast Play features. The first-generation Chromecast will have a time delay, but the second-generation Fast Play feature can establish connections faster and get a seamless experience.

According to leaked documents, Google may also launch Chromecast Audio, which allows Chromecast to directly support any speaker and audio system via an auxiliary coil. This feature also supports multiple rooms, giving users a high-quality audio experience. If you use the scene, it is probably to turn your home's vintage audio into a wireless audio.

Not long ago, Apple just released the fourth generation of set-top boxes Apple TV, and said "application is the future of television." In contrast, Chromecast is much simpler and is equivalent to a mobile tablet projection device, but Google has its own TV system Android TV (rejecting previous Google TV). Coupled with other domestic Internet TV, who can make us love television again?
