As shown in Figure 1, a kind of advertisement filter method based on cloud computing that the embodiment of the present invention provides, described method comprises the steps:
S10, initialization cloud computing server data center, set up TV commercials database;
Before realizing advertisement filter at unlatching television advertising measuring ability, need first initialization cloud computing server data center, namely need set up a TV commercials database at cloud computing server.The initial information of TV commercials database, can obtain by the TV commercials information that provides from the Internet and TV station.
S20, from the audio, video data received, intercept an audio frequency and/or video segment data periodically;
In this step, what intercept can be section audio fragment data or a video segment data, also can be one section of audio frequency and video fragment data simultaneously, utilize the fragment data of described intercepting to mate with the advertising programme database being stored in cloud computing server data center, thus reach the object of advertisement filter.
In embodiments of the present invention, data space shared by voice data is less, in transmission, storage and processing procedure, can process comparatively flexibly and effectively, under the preferred implementation of the therefore embodiment of the present invention, periodically audio clip data is intercepted from audio, video data, and described audio clip data is sent to cloud computing server and advertising programme database carries out matching treatment, correspondingly, for the ad data stored in described advertising programme database too for voice data.
For the described audio frequency that intercepts periodically and/or video segment data, it intercepts the cycle can be arbitrary time span of user's setting, but in actual application, if the intercepting cycle arranged is excessive, then easy by useful non-ad content filtration, in order to improve the accuracy of advertisement filter, for audio frequency and/or the video segment data of described intercepting, it is the smaller the better that it intercepts the cycle.
S30, described audio frequency and/or video segment data to be mated with the advertising programme database being deployed in cloud computing server data center, if the match is successful, then carry out zapping process.
In this step, rear coupling is mated unsuccessful if described audio frequency and/or video segment data and advertising programme database are carried out, then repeat above-mentioned steps S20, now, system does not perform zapping process, still perform and the audio, video data received decoded and is play, but still can intercept an audio frequency and/or video segment data periodically and this audio frequency and/or video segment data are continued mail to cloud computing server data center from the audio, video data received and mate with advertising programme database, once the match is successful, then perform zapping process.Wherein, in actual application, it is described that the match is successful is not defined as 100% the match is successful, in order to improve practicality, under a kind of execution mode, can select to assert coupling success when both matching degrees reach 95%, certainly, describedly judge that the selection of mating whether successfully matching degree also can set according to concrete actual conditions according to designer comparatively freely, too much restriction is not done to it here.
Under a kind of preferred implementation, after performing initialization cloud computing server data center and set up TV commercials database, the described advertisement filter method based on cloud computing also comprises the steps:
S11, the electronic program information provided by TV station are obtained advertisement and play audio frequency in the period and/or video data and be updated to advertising programme database.The electronic program information that thered is provided by TV station obtains advertisement, namely by reading electronic program information, wherein advertisement being play audio frequency in the period and/or video data extracts, being updated to afterwards in the advertising programme database of cloud computing server data center.
