The invention discloses a method for editing start-up music of a television and a television capable of editing start-up music. A media player plays music data from a USB interface or on-line music data from a network, a main processor receives a command for setting a start point and an end point from an input control device to select a music section in the music playing process, and a music encoder is controlled by the main processor to encode and store the music section. When the television starts up, the media player is controlled by the main processor to automatically call out the music section from a storage and play the music so as to form the start-up music, thereby realizing that the television can play music in the start-up process and preventing users from feeling bored and being at a loss what to do in the long start-up process of the television. Because the start-up music can be edited, users can set their own favorite songs or voice of their babies as the start-up music, thereby enjoying the music tone edited by themselves in the start-up process without forcedly waiting. Besides, the start-up music can show the warmness of the family and express individuality.
