''Watch TV'' Application

I need a "Watch TV" application to run via Windows and also Mac platforms. The software should let the user watch tv channels and listen to radios online with the application. I'm looking for a coder which was experienced with the same subject before. In addition to the application, it should provide the user to watch over 4k tv channels, so these channels should be ready with the application. I'll have full rights to the application. Please contact with me about the details. I highly interested in talking with **experienced coders** with the similar project before. Thanks
