Embodiment
Below in conjunction with accompanying drawing, one exemplary embodiment of the present invention is explained, comprising the various details of the embodiment of the present invention, to help understanding, they should be thought to be only exemplary.Therefore, those of ordinary skills will be appreciated that, can make various changes and modification to the embodiments described herein, and can not deviate from scope and spirit of the present invention.Equally, for clarity and conciseness, in following description, omitted the description to known function and structure.
Fig. 1 is according to the schematic diagram of the chief component of the system of the transmission of the embodiment of the present invention and output information.As shown in Figure 1, transmit and the system of output information mainly comprise server 1 and terminal equipment 3,4 ... N, they connect via the Internet.In server 1, be provided with the device 11 of transmission information; In each terminal equipment, be provided with the device 31 of output information, clear for illustrating, in figure only shown in terminal equipment 3.
In the device 11 of transmission information, mainly comprise code modulation module 111, audio mixing module 112 and output module 113.When operation, by code modulation module 111, network address is formed to acoustic coding signal through coded modulation; By audio mixing module 112, the audio signal in the audio/video program of this acoustic coding signal and preliminary election is carried out to audio mixing again; Finally by the audio/video program after output module 113 output audio mixings.This audio/video program is received by terminal equipment 3 via the Internet 2.
The acoustic coding signal being obtained by above-mentioned network address will be extracted and be obtained by terminal equipment 3, and for the ease of terminal equipment 3 these acoustic coding signals of identification, this acoustic coding signal preferably has some features, for example, be signal frequency coverage feature; Also can be signal in time domain, frequency domain, or the feature of the Energy distribution of some or several transform domains (including but not limited to discrete cosine transform domain, wavelet transformed domain); Can also be in audio signal, to comprise the features such as verification and error correction coding.
Terminal equipment 3 is generally personal computer or smart mobile phone, has video playback capability.The device 31 of the output information in terminal equipment 3 mainly comprises playing module 311, mould/number conversion module 312, extraction module 313, processing module 314 and message output module 315.In when operation, by playing module 311 for playing audio/video programs; Mould/number conversion module 312 is when playing module 311 playing audio/video programs, audio signal in this audio/video program is carried out to mould/number conversion, by extraction module 313, according to the feature of preliminary election, from the audio signal mould/number conversion, extract audio signal, by this audio signal of 314 pairs of extractions of processing module, successively carried out that rectification is processed and decoding processing obtains network address, by message output module 315, obtained information the output of this network address, so realized the pushing network information to user.
The acoustic coding signal providing for code modulation module 111, audio mixing module 112 can be carried out audio mixing by the audio signal of the assigned address (i.e. the reproduction time place of appointment) in itself and audio/video program.Correspondingly, when audio/video program is played to this assigned address, corresponding to the information in the network address of tut code signal, be pushed to user, can realize and push the information pushing relevant to a certain video content scene, for example, personage in the film that user watches wears the clothes of a certain pattern, and user is interested in these clothes; According to above-mentioned processing mode, can be by the online merchants' of the similar pattern clothes of sale information pushing to user.
From above description, can find out, code modulation module in server forms acoustic coding signal by network address through coded modulation, this acoustic coding signal arrives with audio/video program terminal equipment the processed network address that obtains that user uses, to user, push again the content of this network address, because can be by the artificial chosen content network address relevant with audio frequency and video in advance, transfer to code modulation module to process, so the information and the audio-video frequency content that push to user have correlation, contribute to improve the interest of user to pushed information.
Basic principle of the present invention has below been described in conjunction with specific embodiments, but, it is to be noted, for those of ordinary skill in the art, can understand whole or any steps or the parts of method and apparatus of the present invention, can be in the network of any calculation element (comprising processor, storage medium etc.) or calculation element, with hardware, firmware, software or their combination, realized, this is that those of ordinary skills use their basic programming skill just can realize in the situation that having read explanation of the present invention.
