Google Cast and ChromeCast

Google Cast and ChromeCast

Google Cast, like DLNA, AirPlay and Miracast, is a screen projection technology.
Awind WiCS -2100 wireless sharing collaboration products support both Google Cast and ChromeCast.

How Google Cast works:

The sender app uses SDK to send the media content that needs to be screened to the Google server, and the server informs the receiver play (so both the sender and the receiver must have access to the Google server). The receiver runs a browser, which loads a corresponding web page according to the app ID and media information of the sender. This web page is provided by the developer of the app of the sender and is responsible for playing the corresponding media content. Even if the receiver is Audio only hardware like Chromecast Audio, the page will load and render.

Google Cast differs from apple’s AirPlay or DLNA in that it relies on Google servers, which means you have to be connected to the Internet to use them. If there is only one LAN, it won’t work. 2 it is after two player of the receiving end itself provided by the receiving end, developers only need to provide to play the contents of the can, but Google Cast app is the need to provide their own the receiving end, the benefit is that developers can be highly customizable (you can customize the UI, for example, or join rolling barrage, lyrics, music visualization such as complex function), although the receiver often run is not Android open operating system, but because the receiver is the nature of the web app, so the development difficulty is not high.

ChromeCast and Google Cast

From the official website of Google Cast, we can see that the role of Google Cast is to send the contents of small screens (such as mobile phones, tablets and laptops) to large-screen devices (Google TV and chromeCast) through WIFI for playing. To summarize, it provides multi-screen interaction function from small-screen devices to large-screen devices. What Google Cast does is to provide SDKS for application expenses based on different platforms, such as the sending end and the receiving end, such as IOS, Android and Chrome browser, and the receiving end, such as Google TV and chromeCast, etc. It can be said that this set of solutions is relatively large and complete (in terms of the platforms it covers).

Chrome Cast is actually a concrete implementation of mechanism of Google Cast. This implementation is characterized by the fact that the receiver chromeCast Dongle is provided by Google itself, and the developer’s burden is only limited to the application development of the sending terminal platform. Of course, the flexibility of the sending terminal is also limited to the Google Cast API provided by Google.

Summarize Google Cast and Chrome Cast, is Google Cast provides connectivity between a set of equipment of the API, and chromeCast technology is the implementation of this set of apis, the advantages of this implementation is for application developers using Google Cast API to develop flexibility (of course this can also be considered to be the technology can not support all the limitations of the app).
