Abstract
Disclosed is a bit rate switching method and device for a smart television. The method comprises: obtaining a current bit rate according to an average network bandwidth in the process of playing a first data source of multimedia data; and when the current bit rate is greater than a first bit rate, determining a difference value between the current bit rate and the first bit rate; when the current bit rate is less than the first bit rate, determining a difference value between the first bit rate and the current bit rate; and according to a comparison result of a trigger threshold and a difference value between the current bit rate and the first bit rate or a difference value between the first bit rate and the current bit rate, retrieving a second data source of the multimedia data from the server for playing or continuing retrieving the first data source for playing. In the process of playing multimedia data, the present application can automatically switch a bit rate matched with a network bandwidth according to the change in a network bandwidth, can solve the problem that the bit rate is required to be manually switched when a person watches a television program, and can guarantee the smooth and clear watching of a video, thereby simplifying user operations and improving the user experience.
