Abstract
The invention provides a method for monitoring DTV (digital television) audio in real time via a mobile terminal. A service monitoring program is run in a DTV to monitor a certain network port of the TCP (transmission control protocol); if a cellphone request is monitored, DTV audio data is acquired and transmitted to the mobile terminal; the mobile terminal is used to play the audio data in real time. The DTV audio is shared via the mobile terminal, audio played on the DTV can be muted, the audio can enter ears of a watcher only while visuality of the DTV is guaranteed, for example, the audio of the DTV is played on the mobile terminal only, a user listens to the audio of the DTV with a headset, a good mute environment is created for the people around who are not watching the DTV, the sense of watching the DTV is not changed, and harmony is realized.
Description
Technical field
The present invention relates to a kind of method that mobile terminal real-time listening DTV holds audio frequency, particularly relate to a kind of method that mobile terminal real-time listening DTV being applicable to intelligent television holds audio frequency.
Background technology
Along with the development of intelligent television, the demand of user to the service that TV provides is increasing.Such as, when watching TV, sound of television can give surrounding in the certain noise jamming of the people doing other thing, even if volume be transferred to very low, can not shield this interference completely.In order to do not want to bother to home other people, in prior art, everybody can select at mobile terminal viewing mobile network TV, a secluded place viewing can be looked for like this, and can earphone be brought, to realize a quiet environment in outside, but, adopt mobile terminal viewing mobile network TV certainly will reduce the visual experience of viewing television, and for needing the mobile terminal of charging, long-term persistence can not be kept.
How while the visual experience that can ensure television, sound can be made again only to enter in the ear of beholder, such as, just the audio frequency of television is play in mobile terminal, user listens to the audio frequency of television with earphone, impels not watch TV to surrounding and and manufacture a good squelch, and does not change the visual experience of television viewing, realize harmonious, be one we need the technical problem of solution badly.
FFmpeg is the Audio and Video stream scheme of an open-source cross-platform, belongs to free software, adopts LGPL or GPL licence (assembly selected according to you).It provide recording, conversion and the total solution of fluidisation audio frequency and video.It contains FA audio/video encoding and decoding storehouse libavcodec, in order to ensure high portable and encoding and decoding quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that audio frequency that DTV can be made to hold carries out in mobile terminal playing in real time.
The technical solution used in the present invention is as follows: a kind of mobile terminal real-time listening DTV holds the method for audio frequency, implementation method is: certain network port holding an operation services listen program listens tcp at DTV, when listening to handset requests, got off to be sent to mobile terminal by the audio data collecting of DTV, mobile terminal is responsible for playing realaudio data.
As preferably, concrete grammar step is:
One, mobile terminal sends audio frequency sharing request to DTV end;
Two, DTV termination is by after the request of mobile terminal, DTV audio signal is converted to mobile terminal audio signal broadcast format and sends it to mobile terminal;
Three, mobile terminal is play after the audio signal decoding received.
As preferably, described step one also comprises: the access request responding mobile terminal after the request permissions of DTV end checking mobile terminal again.
As preferably, the method for described DTV end checking mobile terminal request permissions is: mobile terminal realizes the access to DTV end by login interface.
As preferably, the audio data collecting of DTV gets off and is sent to mobile terminal through the http agreement made by oneself by the described network port.
As preferably, described self-defining http agreement refer to include in self-defining http header that audio format describes, the number of audio sample rate and code check and channel.
As preferably, in described step 2, adopt encoder server that DTV audio signal is converted to mobile terminal audio signal broadcast format.
As preferably, described encoder server is FFmpeg.
As preferably, the audio format that described mobile terminal receives is MP3 format.
As preferably, described mobile terminal is mobile phone or Pad.
Compared with prior art, the invention has the beneficial effects as follows: share DTV by mobile terminal and hold audio frequency, audio setting television can play is quiet, while the visual experience that can ensure television, sound can be made again only to enter in the ear of beholder, such as, just the audio frequency of television is play in mobile terminal, user listens to the audio frequency of television with earphone, impel and do not watch TV to surrounding and and manufacture a good squelch, and do not change the visual experience of television viewing, realize harmonious coexistence.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
