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

Embodiment Construction

[0016] figure 1 It is a block diagram of an adaptive volume adjustment system according to the present invention.

[0017] like figure 1 As shown, the system consists of four modules: user input module, control module, storage module, and playback module. The control module can read or store the data in the storage module through the control commands input by the user input module, and the calculated parameters Pass it to the playback module. The playback module plays according to the final volume parameter. Wherein the storage module stores the main volume value, the volume correction value of each channel and the specific operation record (the volume offset record when changing the channel).

[0018] figure 2 It is a flow chart of initialization of the adaptive volume adjustment system according to the present invention.

[0019] like figure 2 As shown, when the user uses it for the first time or the system is re-initialized (for example, updating channel programs), ...

Abstract

The present invention relates to a method and equipment for adaptive volume adjustment during channel switching. The method includes: determining that the viewing time of the first channel after switching exceeds a first time threshold; determining that there is a viewing time before the first channel a second channel whose time exceeds a second time threshold; determine a volume correction estimate for the time period from the end of watching the second channel to switching to the first channel; and update the first channel with the volume correction estimate The channel's current volume modifier. The scheme of the present invention associates the two different operations of channel switching and volume adjustment by the user, and adopts a unilateral correction method to adaptively adjust the volume after channel switching, which solves the problem that users often have to perform channel switching. Problem with volume adjustment.

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...
