The viewing quality of the movie "Frozen" is better when it is downloaded as opposed to being streamed. The viewing quality of streaming video depends on many outside factors not related to the quality of the media.
Downloaded video always plays with the same quality as the original download. Streaming video quality, on the other hand, depends on many factors such as the quality of the Internet connection, the amount of traffic going to the streaming source, and the speed of the Web server's connection. Streaming video is not saved on the device used for streaming, and an Internet connection is required each time the movie is played. Downloaded video can be stored on the device which it is downloaded to be watched later, although the download must be complete before viewing.
