Embodiment 1

[0075] refer to figure 1 , shows a flow chart of a volume adjustment method according to Embodiment 1 of the present invention. The volume adjustment method may specifically include the following steps:

[0076] Step 101, receiving sampling points of audio data corresponding to the current channel, and collecting volumes of audio data corresponding to each sampling point.

[0077] When watching a certain TV channel, for the audio played, the set-top box will receive the sampling points of the audio data corresponding to the current channel, then analyze and process the sampling points of these audio data, and send them to the playback device for playback after processing.

[0078] In the embodiment of the present invention, it is necessary to perform real-time volume adjustment processing for the sampling points of the received audio data. Therefore, after receiving the sampling points of the audio data corresponding to the current channel, the volume of the audio data corres...

Embodiment 2

[0091] In the embodiment of the present invention, the overall processing process of audio data is firstly introduced. refer to figure 2 , shows a schematic diagram of an audio data processing flow in Embodiment 2 of the present invention. The audio data processing flow is specifically described as follows:

[0092] 1. The tuner (Tuner) tuner locks the current channel and starts to receive data corresponding to the current channel (such as audio data, video data, etc.).

[0093] 2. The tuner (Tuner) transmits the received data to the splitter (Demux).

[0094] 3. Filter the selected audio data from the TS (Transport Stream, transport stream) through the splitter component to obtain the audio PES (Paketized Elementary Stream, packaged elementary stream). In the TS analysis process, there is such a concept as PID (Packet Identifier, packet identification code). TS is composed of various data. The data in a TS packet can be video data, audio data, filling data, etc. , each d...

Embodiment 3

[0147] The volume adjustment method in the third embodiment of the present invention can also be described above figure 2 The post-processing stage in is executed.

[0148] refer to Figure 4 , shows a flow chart of a volume adjustment method according to Embodiment 3 of the present invention. The volume adjustment method may include the following steps:

[0149] Step 401, receiving sampling points of audio data corresponding to the current channel, and collecting volumes of audio data corresponding to each sampling point.

[0150] Step 402, determine the number of sampling points in the sub-time period corresponding to the current channel.

[0151] Step 403, determine the sub-time period to be played.

[0152] Step 404 , according to the volume of audio data corresponding to each sampling point and the number of sampling points in the sub-time period, adjust the audio data volume for the sampling points of the sub-time period to be played.

[0153] Steps 401 to 404 in t...

Abstract

The invention provides a volume adjustment method, a device and a set-top box to solve the problem that the existing volume adjustment method is too cumbersome, poor in versatility, and unable to deal with sudden changes in sound in a single channel. The method includes: receiving the sampling points of the audio data corresponding to the current channel, and collecting the volume of the audio data corresponding to each sampling point; determining the number of sampling points in the sub-time period corresponding to the current channel; determining the sub-time period to be played; according to each The volume of the audio data corresponding to the sampling point and the number of sampling points in the sub-time period, adjust the audio data volume for the sampling point of the sub-time period to be played; judge whether to switch channels, if not, return to determine the sub-time to be played segment; if yes, return to the step of receiving the sampling point of the audio data corresponding to the current channel. The present invention can avoid the phenomenon of sound mutation when switching channels or continuously playing under the same channel, and has simple process and strong universality.

Description

technical field [0001] The invention relates to the technical field of multimedia, in particular to a volume adjustment method, a volume adjustment device, and a set-top box. Background technique [0002] In recent years, with the rapid development of multimedia technology, various playback terminals are also developing rapidly, and their functions are increasing day by day. Taking the TV set-top box as an example, because it can provide users with higher-quality sound and picture, and meet various needs of users, it has become an indispensable device in people's life. However, the following problems exist in the application of the TV set-top box at present: when the user watches TV, the problem of inconsistency in the volume of the sound between various channels often occurs, or the problem of a sudden change of the sound when switching between programs and advertisements in a single channel. [0003] In view of the above problems, the following two methods are usually ado...
