Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
In embodiments of the present invention, be divided into basic volume and compensation volume two parts by volume with set-top box, at different channels, make that the actual output volume value of each channel is that basic volume adds the compensation volume, thereby effectively regulate and balance the actual output volume value of different channel.
Fig. 1 shows the method realization flow of the balancing set-top box output volume that the embodiment of the invention provides, and details are as follows:
In step S101, receive the information table that comprises volume compensation information, and from described information table, resolve the volume compensation value that obtains each channel.
As one embodiment of the present of invention, the set-top box volume is divided into two parts, promptly basic volume and compensation volume.Basic volume is the total values of all channels, and the compensation volume all has an independent value at each different channel.
In embodiments of the present invention, because the channel that present various places operator is provided is many,, will bother very much if the user wants oneself be provided with the compensation volume of each channel.Therefore, Virtual network operator estimates the volume compensation value of this channel according to the actual volume of each channel.(ElectronicProgram Guide, EPG) software for editing generates the information table with all channel volume compensation information, broadcasts server with EPG again information table is sent on the network by electric program menu then.Set-top box will have the information table of volume compensation information when program searching, described information table includes but not limited to BAT bouquet association table (BouquetAssociation Table, BAT), SDT Service Description Table (Service Description Table, SDT), network information table (Network Information Table, NIT), Program Map Table (Program Map Table, and from table, parse the volume compensation value of each channel PMT) etc..When carrying out situations such as program searching or switching channels as the user, the information table that the automatic search of set-top box will have volume compensation information receives, and from table, parse the corresponding respectively volume compensation value of each different channel, the volume compensation initial value that this volume compensation value is exactly a channel.
In step S102, regulate actual output volume according to the volume compensation value that basic volume and described parsing obtain.
In this step, set-top box is regulated actual output volume according to basic volume and the described volume compensation value of obtaining, actual output volume be basic volume and compensation volume and, so just allow the volume of all channels on actual output effect, reach unified.
In embodiments of the present invention, basic volume is the total values of all channels, and the compensation volume is all to have one at each channel.When user's switching channels, regulate actual output volume according to basic volume and volume compensation value, the actual output volume value of channel is that basic volume adds the compensation volume.As basic volume is set as 20, one in central authorities are that 20 o'clock actual output sounds are smaller in volume, and Shenzhen satellite TV is that 20 o'clock actual sounds are bigger in volume.Like this we just central authorities' compensation volume can be made as+3, and Shenzhen satellite TV compensation volume is-2.When the user switched to central one, this moment, central one actual output volume was 20+3=23.When the user switched to Shenzhen satellite TV, this moment, the actual output volume of Shenzhen satellite TV was 20+ (2)=18, thus effectively balance actual output volume.
In embodiments of the present invention, when the user adjusts volume when watching program, what adjusted this moment is the basic volume of all channels.This is for convenience, and environment is different sometimes, needs the problem of tracking channel volume.Surrounding environment may be more noisy when seeing TV by day, and at this moment the ratio that is provided with of all channel volume universal demands is higher, but to during the late into the night since around very quiet, it is lower that volume may need to be provided with.By basic volume is set, as long as adjusted basic volume, the volume of all channels all is adjusted, and is user-friendly to.
