Method and apparatus for self-adaption regulating volume when switching frequency channel

Abstract

The invention relates to a method and equipment for carrying out self-adaptive volume adjustment when switching the channels, wherein the method comprises: determining that the watching time of a switched first channel is over a first time threshold; determining that a second channel of which watching time is over a second time threshold exists before the first channel; determining a volume correction evaluating value during the period from finishing watching the second channel to switching to the first channel; and updating current volume correction value of the first channel with the volume correction evaluating value. The technical scheme according to the invention associates the channel switching operation with the volume adjusting operation, and carries out self-adaptive adjustment on volume after switching channel by means of unilateral correction, in order to solve problem of indisputable volume adjustment occurs when the user switches the channel.

Description

technical field [0001] The invention relates to a method for self-adaptive volume adjustment when switching channels and a TV, a set-top box, a radio or related equipment for realizing the method. Background technique [0002] Currently, TVs, set-top boxes, radios and other products have become an indispensable part of our daily life. In the above-mentioned existing products, the audio control is controlled by a single volume value. However, because the audio sources are generally different, the strength of the audio signal when modulated is also different, so the volume is not balanced between channels or between programs in a channel. In short, when we watch TV, we often encounter the situation that the sound is loud and soft. There are two reasons for this difference in volume, one is the volume imbalance between channels, and the other is the imbalance between programs. Among them, the former is a systematic error, which is stable to a certain extent. [0003] Regard...

Problems solved by technology

At present, there are two possible methods: first, the error value is manually set by the user. This method is effective, but the operation is complicated, inconsistent with the existing usage habits, and it is not convenient for the public to use.

Second, the error value is obtained by calculating the sound intensity of each channel. This method is consistent with the existing usage habits, transparent to user operations, and easy to promote. However, its judgment logic is complicated and it is particularly susceptible to random errors (i.e. Interference between errors), poor accuracy, high cost
