A method and system for switching media streams of a video in a client system. The media streams are made available to the client system by a content providing system. A first media stream received from the content providing system is played in a SHOW mode in the client system. An environmental change in an environment within or adjacent to the client system is detected, resulting in executing a procedure for deciding whether to switch from playing the first media stream to playing a second media stream differing from the first media stream. The executed procedure decides to make the switch. The switch is made to playing the second media stream in the SHOW mode as the second media stream is being received from the content providing system in response having been requested from the content providing system. The switching preserves content continuity of the video.
