摘要： Provided is a method of improving a channel switching speed in a digital television (TV) receiver. The method includes: generating transport stream packets by channel tuning and demodulating a broadcasting signal of a channel selected by the channel change instruction; outputting the transport stream packets before completion of tuning and demodulating of the broadcast signal; and generating video and/or audio data by demultiplexing and decoding the outputted transport stream packets. In addition, a digital TV receiver applying the improvement of the channel switching speed is provided. The digital TV receiver includes a tuning and demodulating unit generating transport stream packets by tuning and demodulating a broadcasting signal of a broadcasting channel selected by a channel change instruction and outputting the transport stream packets before completion of the tuning and demodulation of the transport stream packets. The digital TV receiver starts screen mute in response to the channel change instruction and terminates the screen mute when a normal image display is possible by using the transport stream packets output from the tuning and demodulating unit. Therefore, the channel switching speed increases as compared with a case where the improvement of the channel switching speed is attempted by using the transport stream packets.
