While a user of a digital television gives a command to switch from a first channel to a second channel, a comparison between a first remembered volume of the first channel and a second remembered volume of the second channel is provided. According to the result of the comparison, a currently-used volume of the second channel may be adjusted from the first remembered volume to the second remembered volume iteratively and by step volumes so that the adjustment of the currently-used volume of the later channel is not annoying for the user. Moreover, the user is also allowed in determining a preferred volume to be the currently-used volume of the second channel. While the user of the digital television flips between channels, unnecessary updates in a volume setting of the second channel are abandoned. |
