Abstract: A method and system for playing background music and key tone based on an embedded browser, and a digital television receiving terminal. The method comprises: analyzing and downloading web data, intercepting protocol registration events, and sending a background music start command when the background music need to be played; analyzing transport stream (TS) data pushed by a server, obtaining data required for playing the background music, and playing the background music; and receiving a key operation command from a user, analyzing the TS data pushed by the server when playing the background music, obtaining data required for playing key tone, and playing the key tone instructed in the key operation command. With the preceding method, system and digital television receiving terminal, defects in concurrently playing multi-channel audio data are overcome and the background music and key tone can be played concurrently.
