Description
Technical field
The present invention relates to TV technology, relate in particular to a kind of start shooting advertisement audio playing apparatus and method, apply the television system of this start advertisement audio playing apparatus.
Background technology
Intelligent television is to have carried operating system, the sustainable new tv product that function is expanded and upgraded.The basic task of intelligent television mainly comprises realizes Media Stream as functions such as the demodulation such as video flowing, audio stream, decoding and demonstrations; Development along with Internet technology, the attainable allocation function of intelligent television is enriched constantly perfect, except possessing the most basic above-mentioned digital television business function, some new value-added service functions have also been increased, such as carrying out remote living broadcast, video request program, web page browsing, digital music, network video telephone, game interactive and stock exchange etc., greatly enriched people's life.
In prior art, first the pre-stored one section of start advertisement of meeting in the storage chip of most intelligent televisions, therefore, after intelligent television start, can play one section of start advertisement, usings this as new profit model.Start advertisement generally cannot be skipped, and after start advertisement finishes, just can play TV programme.
The subject matter that prior art exists is that the voice-frequency channel of start advertisement is also pre-stored in the storage chip of intelligent television conventionally, and the advertisement audio frequency acquiescence path of conventionally starting shooting is generally loud speaker path; After intelligent television dispatches from the factory, start advertisement audio frequency acquiescence path cannot be changed, and the advertisement audio frequency of starting shooting can only be exported by loud speaker path; For example, if intelligent television does not connect any external audio frequency equipment, with loud speaker path, by the loud speaker of television system self, export start advertisement audio frequency, be connected with earphone intelligent television being detected, still with loud speaker path by the loud speaker output start advertisement audio frequency of television system self; And unlike playing TV programme audio frequency, when intelligent television being detected and being connected with earphone, with earphone path, by earphone, export TV programme audio frequency, do not detect while not connecting any external audio frequency equipment, with sample loud speaker path, by the loud speaker of television system self, export TV programme audio frequency.This is that the operating system of the upper operation of the CPU of intelligent television does not also start completely conventionally, therefore cannot automatically complete the switching of voice-frequency channel due to when playing start advertisement.
But, in most cases, while being connected with the external audio frequency equipment such as earphone in television system, showing that the loud speaker that user does not wish that audio frequency passes through television system self exports, thereby avoid the perception by people around, to reduce the interference that other people are caused; And intelligent television of the prior art is when playing start advertisement, even if be connected with the external audio frequency equipment such as earphone, still can, from by the loud speaker output audio of television system self, can not meet consumer's actual demand.
Therefore, provide a kind of start advertisement voice-frequency channel broadcasting scheme that can realize easily the switching of start advertisement voice-frequency channel to be necessary.
Summary of the invention
The object of the invention is to for the subproblem in background technology or whole issue, provide a kind of and can realize easily start advertisement audio playing apparatus and the method that start advertisement voice-frequency channel switches; Further, the present invention also provides the television system of this start advertisement audio playing apparatus of a kind of application.
Concrete, described start advertisement audio playing apparatus, is applied to play the television system of start advertisement, and described television system has a plurality of voice-frequency channels; Described device comprises:
Voice-frequency channel handover module, for according to selection instruction, start advertisement audio frequency acquiescence path being switched to one of described a plurality of voice-frequency channels, and is stored in predeterminated position by switching result;
Start advertisement playing module, for when the described television system start, reads start advertisement audio frequency acquiescence path from described predeterminated position, and with described start advertisement audio frequency acquiescence path output start advertisement audio frequency.
Described start advertisement audio frequency playing method, is applied to play the television system of start advertisement, and described television system has a plurality of voice-frequency channels; Described method comprises:
Step 1. switches to one of described a plurality of voice-frequency channels according to selection instruction by start advertisement audio frequency acquiescence path, and switching result is stored in to predeterminated position;
Step 2., when described television system start, reads start advertisement audio frequency acquiescence path from described predeterminated position, and with described start advertisement audio frequency acquiescence path output start advertisement audio frequency.
Described television system, comprises above-mentioned start advertisement audio playing apparatus.
From above technical scheme, in start advertisement audio playing apparatus provided by the present invention and method, owing to can start advertisement audio frequency acquiescence path being switched to one of a plurality of voice-frequency channels of television system according to selection instruction, and switching result is stored in to predeterminated position, and when starting shooting, television system plays start advertisement with the start advertisement audio frequency acquiescence path switching; Like this, if the advertisement audio frequency of need to starting shooting is exported from a certain voice-frequency channel, only start advertisement audio frequency acquiescence path need to be switched to this voice-frequency channel, after the each start of television system, all can be with this voice-frequency channel output start advertisement; Therefore, by the present invention, can realize very easily the switching of start advertisement voice-frequency channel.
