Abstract
The invention provides a system and a method for remotely monitoring DTV (digital television) audio in real time via a mobile terminal. Access strength of television audio signals is enhanced through a remote router WIFI (wireless fidelity) access point, and television audio transmission can be timely and smooth. The mobile terminal shares the DTV audio through a main or auxiliary router WIFI access point, the television audio can be remotely monitored in real time, timeliness and convenience are achieved, investment is low, and resource waste is maximally decreased.
Description
Technical field
The present invention relates to the system and method that the remote real-time listening DTV in a kind of mobile terminal holds audio frequency, particularly relate to the system and method that a kind of remote real-time listening DTV in mobile terminal 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, user is when kitchen is busy, and time is up for a certain TV programme oneself be concerned about, but for fear of busy not free viewing, in prior art, be mostly a small tv to be installed for playing TV programme in real time in kitchen, but do like this, one is that cost is high, and user also not necessarily can see, may just listen, see the same once in a while, two are, frequency of utilization is not high yet, causes the wasting of resources.
Again such as, what user wanted to monitor parlor broadcasting now when bedroom is any TV programme, to judge whether dare interest at oneself.
Intelligent sliding moved end is as now more and more general appliance and electronic, increasing function can be realized, mobile TV is also more and more general simultaneously, but there is poor real, and not free viewing time busy, only need to listen and can meet the demands, in addition, if there is video to show simultaneously, there is the wasting of resources, mobile terminal is as charge prepd simultaneously, if load is large, unnecessary waste can be brought to battery electric quantity, therefore when only needing program to listen to, how to realize simply and effectively listening to TV programme at a distance, become the technical problem that we are urgently to be resolved hurrily.
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 ofly can hold the system and method for audio frequency by remote convenient and swift real-time listening DTV.
The technical solution used in the present invention is as follows: the remote real-time listening DTV in a kind of mobile terminal holds the system of audio frequency, it is characterized in that: comprise DTV end, and is held by active router and DTV and realize accessing and the mobile terminal of Signal transmissions.
As preferably, also comprise: from router, form local area network (LAN) with active router.
As preferably, described mobile terminal is mobile phone or Pad.
Hold the monitor method of audio system based on the remote real-time listening DTV in above-mentioned mobile terminal, concrete grammar step is:
One, mobile terminal connection route device network, 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 also comprises, connection position, mobile terminal from router wifi access point, to be held to DTV by the local area network (LAN) that formed from router and active router and send audio frequency sharing request.
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; 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.
Compared with prior art, the invention has the beneficial effects as follows: by main road by or point route wifi access point, mobile terminal share DTV hold audio frequency, the remote real-time listening to sound of television can be realized, in real time, convenient, invest little, and farthest reduce the waste of resource.
Accompanying drawing explanation
Fig. 1 is the system frame structure schematic diagram of the present invention's wherein specific embodiment.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, 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.
