Abstract
An audio data recording method for the receiver of digital player includes choosing a music channel according to the forecast information of electronic programs, receiving the high-sound-quality audio data from the channel, and directly recording them on CD or DVD without compression.
Description
(1) technical field
The invention relates to the recording method of the music voice data of digital broadcasting receiver, refer in particular to multiple electronic programming schedule informations such as utilizing digital broadcast channel and broadcast program information, with the digital music playing audio-fequency data, the recording method of the music voice data of a kind of digital broadcasting receiver of record, storage on CDs such as CD or DVD.
(2) background technology
Generally, digital broadcast comprises, digital satellite broadcast, digital cable broadcast, digital radio broadcast etc., be set top box digital broadcasting receiver such as (Set Top Box) with this reception, receive the digital broadcast signal that MPEG transmits stream, after returning to original video and audio signal and carrying out signal processing, its video and audio signal are transmitted and output to general television set etc., make the user can the needed broadcast program of audiovisual.
For example, as shown in Figure 1, play and carry out signal processing in order to receive digital satellite, digital broadcasting receiver 300 will with receive the satellite antenna 200 of playing the digital broadcast signal that satellite 100 sends and be connected.Above-mentioned satellite antenna 200 comprises, the digital satellite play signal is converted to the medium frequency in 1GHz zone, when going forward side by side line advance, also is provided with and reduces LNB (the Low Noise Block down) converter that disturbs.
Thereupon, above-mentioned digital broadcasting receiver 300 receives the medium frequency of removing the 1GHz zone of interference by above-mentioned LNB converter, as previously described, MPEG is transmitted the digital broadcast signal of stream, after returning to original video and audio signal and carrying out signal processing, its video and audio signal are sent to sounds such as general television set 400 look equipment and play output.
In addition, above-mentioned digital broadcasting receiver 300, multiple electronic programming advance notice (EPG) information such as broadcasting channel that digital broadcast information on services SI (Service Information) is transmitted and broadcast program information, are read at retrieval from above-mentioned information on services (SI), and are stored in the device and manage.
In addition, requirement according to the user, with above-mentioned electronic programming schedule information, screen display OSD (On Screen Display) picture output by television set 400, so user with above-mentioned digital broadcasting receiver 300, utilize electronic programming schedule information, retrieve broadcasting channel or the broadcast program of oneself liking and confirm by the OSD picture output of television set 400.
On the other hand, release recently provides the digital music broadcasting channel of high tone quality digital audio-frequency data specially, be subjected to liking of users deeply, have the user of above-mentioned digital broadcasting receiver, normally, audio frequency and video data that above-mentioned music channel is provided, after recording the hard disk (HDD) and storage of this digital broadcasting receiver, only select its voice data, copy on the CDs such as CD or DVD, utilize portable audio player again, the voice data that writes down on the broadcast CD is also listened to.
But, for the voice data of only selecting high tone quality and duplicate, storing, the audio frequency and the video data that above-mentioned music channel will be provided, record, store on the hard disk, with state that CD drive etc. is connected under, select, duplicate above-mentioned voice data and operate to the complexity of the rapid step of the first-class multistep of CD, and these steps must be operated one by one by the user, therefore have the awkward problem of user.
In addition, above-mentioned voice data with the state recording of compression, store on the hard disk, therefore the problem that voice data tonequality reduces can take place.Again, above-mentioned voice data records on the hard disk with video data, and therefore the problem that can not write down, store more voice data takes place again.
(3) summary of the invention
The objective of the invention is in order to solve above-mentioned prior art problems, a kind of multiple electronic programming schedule informations such as digital broadcast channel and broadcast program information that utilize will be provided, after selecting the music channel, only select the voice data of the high tone quality that provides by above-mentioned music channel, the recording method of the music voice data of the digital broadcasting receiver that on CDs such as CD or DVD, directly writes down, stores with non-compressed state.
The object of the present invention is achieved like this:
A kind of recording method of music voice data of digital broadcasting receiver, its feature comprises:
First step: utilize the electronic programming schedule information, select the music channel;
Second step: the played data with the music channel of above-mentioned selection receives is divided into video data and voice data;
Third step:, select and record on the CD with the voice data of above-mentioned separation.
Effect of the present invention:
The recording method of the music voice data of digital broadcasting receiver of the present invention, be to utilize multiple electronic programming schedule informations such as digital broadcast channel and broadcast program information, after selecting the music channel, the voice data of the high tone quality that provides by above-mentioned music channel only is provided, on CDs such as CD or DVD with the direct record of non-compressed state, storage, therefore the facility of using not only is provided, also can prevent the problem that tonequality that the voice data packed record caused reduces in advance, again record for a long time, store more voice data.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
