The present invention relates to a method of confirming whether a recorded program is voice multicasting, so that a user can confirm whether or not the recorded program is voice multicasting.

In general, in a personal video recorder (PVR), not only digital broadcast recording but also analog broadcast recording is possible, and analog broadcast includes mono broadcasting, stereo broadcasting, and voice multiple broadcasting. Voice multicasting allows Korean and foreign languages to be selectively listened to by the user. When the viewer sets the main voice, L and R channels are output in Korean, and when set to the sub-audio, the L (Left) and R (Right) channels. All foreign languages are output, and if it is set as main voice and sub-voice, Korean is outputted to the L channel and foreign language is outputted to the R channel.

However, there is a problem in the current PVR is recorded and played back only in the language set by the viewer. In other words, when the viewer is recorded while watching the main voice, the recorded program can be played only in Korean, and when the viewer is recorded while watching the sub-audio, the recorded program can be played only in a foreign language. In addition, when the viewer is recorded while watching the main voice + sub-audio, it is possible to listen to the foreign language in the Korean language and the R channel in the L channel, in this case, it is difficult to listen only to Korean or only foreign languages. .

In order to solve this problem, it is desirable to allow the user to select which one to select before playing a voice multi-program while the main voice, sub-audio and (main + minor) voices are all stored. Indication of whether or not the playback program is a voice multiple program should be preceded.

Accordingly, the present invention was developed to satisfy the above necessity, and by allowing the user to check whether the recorded program is voice multicasting through the OSD, the user can use the main audio or sub-audio or The purpose of the present invention is to provide a method for confirming whether a voice is multi-broadcasted in a recorded broadcast program, which can be selected according to a desired one, thereby obtaining a more convenient and diverse voice listening environment.

According to this object, the present invention adds an index, which is predefined to distinguish the voice multiple programs, to the recording time information of the voice multiple programs, and separately to each of the transport packets TP generated when recording the programs. After adding the timestamp while increasing the serial number according to the recording order, it is determined whether the timestamp and the set recording start or end time index information are identical before playback, and if the timestamp is equal to the recording time index information, the multiplexing is performed. The user is notified of the fact so that any one of the voices can be set according to the user's selection.

To this end, the present invention, the first step of adding an index (index), which is predefined to distinguish the voice multiple program, to the recording time information of the voice multiple program;

Apart from the first step, a second step of adding a different time stamp according to the recording order to each of the transport packet generated during program recording;

A third step of comparing a time stamp added in the second step with recording time information added with an index according to the first step when playing a program;                         

A fourth step of notifying the outside that the program to be played is a voice multiple program when the time stamp added in the second step is equal to the recording time information added with an index according to the first step as a result of the comparison of the third step; A method of checking whether a recorded broadcast program is voice multicast is disclosed.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

First, a method of outputting an audio signal of a recorded voice multiple program according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a view for explaining a recording mode used in the present invention, and FIG. A diagram for explaining a reproduction mode of an audio signal recorded according to the present invention.

As shown in FIG. 1, the present invention first shows that under the control of the CPU when the channel matrix 101 of the audio processor 100 determines that a program to be recorded by a CPU (not shown) is a voice multi-program, Decode the SIF (Sound Intermediate Frequency) input from the tuner to output both the main and sub voices.

For example, the present invention defines, in advance, an identifiable flag of an audio multiple program, according to a predetermined recording command, whether the flag is attached to a program to be recorded through a tuner unit not controlled by a CPU or a CPU not shown. If it is determined that the flag is attached to the program. The channel matrix 101 of the audio processor 100 decodes the voice intermediate frequency (SIF) input from the tuner unit so that both the main voice and the sub-audio are output. This aspect is within the scope of the technical spirit of the present invention. Many variations are possible.

On the other hand, if both the main voice and the sub-audio are output through the channel matrix, the main voice and the sub-audio are synthesized and converted into a preset voice standard, for example, I ² S format, such as L / R / L / R, ... Iteratively outputs to the MPEG encoder 104, which uses the MPEG encoder 104 to generate PES (Packed Elementary Stream), PES, and (Primary + Sub) PES, respectively, from a predetermined NTSC video processor. The video PES is generated using the input image information, and the generated video PES and the audio PES are combined to generate a plurality of TP unit packets in the recording order.

That is, when it is determined that the program to be recorded is a voice multiple program, the MPEG encoder 104 repeatedly receives (main + part) voice through the second output matrix 103 provided separately in the audio processor 100, Extract only the channel data to the main voice PES, extract only the R channel data to the sub-voice PES, and extract both L and R channel data to packetize the PES to the (main + sub) voice.

Then, the unitized packet PTP is synthesized by synthesizing the packetized main voice PES, the negative voice PES, and the (main + minor) PES from the NTSC processor to generate a unit transmission packet (TP). Different time stamps are added for each TP) according to the recording order. Preferably, the time stamp is added so that the serial number is increased according to the recording order for each unit transport stream.

Then, the present invention registers the unit packet with the time stamp attached to the TP stream file in the hard disk 106 in TP units under the control of the IDE controller 105 (S505). Separately, under the control of the CPU, a pre-defined index is added to the recording time information of the voice multi-program to register it in the index file provided in the hard disk 106. The above process is summarized as follows.

That is, according to the present invention, an index, which is predefined to distinguish the voice multiple programs, is added to the recording time information of the voice multiple programs before playback, and separately, each unit transmission packet TP generated during recording of the program is separately added. In addition, different time stamps are added in accordance with the recording order and registered in the index file and the TP stream file, respectively.

Subsequently, the regeneration aspect according to the present invention will be described with reference to FIG.

First, in the above-described state, when an IDE (Intergrated Drive Electronics Controller) controller receives a recording / playback command of a predetermined program under the control of the CPU, the timestamp and the recording start set according to the playback command input from the outside are started. Or, it is determined whether or not the same as the end time index information.

As a result of the determination, when the time stamp is the same as the recording start or end time index information, the user can be notified of the fact so that any one of the multiplexed voices can be set according to user selection. For example, when the timestamp is the same as the recording start index information, a preset voice multi user setting OSD (OS Screen Display) is read from the hard disk 106. The MPEG decoder then decodes the read audio multi user setup OSD and pops it on the screen via an NTSC video processor.

As a result, the user can view the pop-up voice multi-user setting OSD to find out whether the current broadcast program is a voice multi-program and select one of the main voice, the sub voice, and the (main + minor) voice.

If the time stamp is the same as the recording end index information, it is preferable to drive the NTSC video processor under CPU control to pop off the pop-up user setting OSD on the screen.

On the other hand, if any one is selected according to the user setting, based on the result, the IDE controller 105 selects any one of the main voice PES, sub-voice PES, (main + minor) voice PES registered in the hard disk 106 Selectively decode and output.

That is, after recording and reproducing a predetermined voice multi-program, the set head of the reproducing voice is detected according to a user setting, and then a TP attached to the detected set head is selectively extracted and the MPEG decoder 107 is set according to the user setting. ) And selectively decodes any one of the main voice PES, the sub-voice PES, and the (main + sub) voice PES to output to the audio processor 100 in a preset voice standard, for example, I ² S format.

Then, the channel matrix 101 and the first output matrix 102 of the audio processor 100 have a predetermined switching matrix for any one voice determined according to a user setting, that is, a main voice, a sub voice, or a (main + minor) voice. Through the speaker 108 to be output to the outside.

As described above, the system to which the present invention is applied sets the recording start and end time index information of the audio multiple program according to the recording command, and separately for each unit transmission packet TP in which a predetermined video PES and audio PES are synthesized. After adding different time stamps according to the recording order, the time stamp is started or stopped by determining whether or not the time stamp is identical to the set recording start or end time index information according to a predetermined program play command input from the outside. If it is the same as the time index information, the user can be notified of the fact so that any one of the multiplexed voices can be set according to user selection.

Next, the TP stream file used in the present invention will be described in more detail with reference to FIGS. 3 and 4, wherein FIG. 3 is a diagram showing the configuration of the TP stream file used in the present invention, and FIG. It is a figure which shows an aspect.

According to the present invention, the recording start and end time index information of a voice multiple program is set according to a recording command, and different time stamps are generated according to the recording order for each unit transmission packet TP in which a predetermined video PES and an audio PES are combined. In addition, as shown in FIG. 3, the start time index information and the end time index information for each voice multiple program are set under the control of the CPU so that they can be registered in an index file separately provided in the hard disk for reference during playback. Separately, TPs separately provided in the hard disk after adding time stamps of increasing serial numbers according to the recording order, for example, for each unit transmission packet (TP) in which predetermined video PES and audio PES are synthesized. Register in stream file in TP unit.

4, the TP stream file used in the present invention is classified and stored in a stream file for each voice multicast program. The matching of the voice multicast program name and the corresponding file is linked through a pointer. In the stream file, the above-described PES information, that is, the video PES information, the main audio PES1, the sub-audio PES2, and the (main + sub) voice PES3 are preferably registered in TP units.

Next, with reference to Figure 5 will be described a preferred embodiment according to the present invention.

First, as shown in FIG. 5, the present invention determines whether a program to be recorded is a voice multiple program according to a predetermined recording command (S501). Ensure that both main and sub voices are output at frequency.

For example, by identifying a flag that can be identified as a voice multiple program in advance, it is determined whether or not the flag is attached to a program to be recorded by a CPU or a tuner unit controlled by the CPU according to an input recording command. The setting flag is attached to the program. It is preferable that the channel matrix of the audio processor outputs both the main voice and the sub-audio at the voice intermediate frequency input from the tuner, but this embodiment can be variously modified without departing from the technical spirit of the present invention. .

On the other hand, if both the main voice and the sub-audio are output through the channel matrix, the main voice and the sub-voice are converted into a predetermined voice standard, for example, the I ² S format, repeatedly such as L / R / L / R, ... It outputs to MPEG encoder, and MPEG encoder generates PES of main voice PES, sub voice PES, and (main + sub) voice respectively, and generates video PES using video information input from predetermined NTSC video processor. A video PES and the audio PES are combined to generate a plurality of unit transmission packets (TPs) in the recording order.

That is, when the program to be recorded is determined as a voice multi-program, the MPEG encoder repeatedly inputs (main + sub) voices through a predetermined output matrix provided separately in the audio processor, extracts only the L channel data, and then transfers the main voice to the main voice PES. After extracting only R channel data, it extracts both L and R channel data, and packetizes them with PES of (main + minor) voice. Then, the unitized packet PTP is synthesized by synthesizing the packetized main voice PES, the sub-voice PES, and the (main + minor) voice PES to the video PES output from the NTSC processor, and generates the unit transmission packet (TP). For each TP), a different time stamp is added according to the recording order (S503).

Thereafter, under the control of the IDE controller, the unit transfer packet TP with the time stamp is registered in the TP stream file in the hard disk in units of TPs (S505). Separately, under the control of the CPU, the recording start and end time indexing information of the voice multiple programs is set (S502) and registered in the index file provided in the hard disk (S504). It is desirable to add a timestamp so that the number is incremented.

Subsequently, in this registered state, when a recording / playback command of a predetermined program is input (S506), the timestamp is periodically checked while performing a playback operation according to a playback command input from the outside (S507), and the timestamp and step (S502). It determines whether or not the same as the recording start or end time index information set in step (S508).

Thus, when the timestamp is equal to the recording start or end time index information (S509), the user is informed of the fact so that any one of the multiplexed voices can be set according to user selection. For example, when the timestamp is the same as the recording start index information, the preset voice multi user setting OSD is popped on the screen (S510).

When the timestamp is the same as the recording end index information (S510), the user setting OSD popped on in step S510 is popped off on the screen (S5110) so that the user can confirm that the playback program is a voice multiple program. In this case, one of the multiplexed voices can be selected according to a user's selection, for example, a main voice, a sub voice, or a (main + minor) voice.

As a result, the user can view the pop-up voice multi-user setting OSD to find out whether the current broadcast program is a voice multi-program and select one of the main voice, the sub voice, and the (main + minor) voice.

On the other hand, if any one is selected according to the user setting, one of the main voice PES, the negative voice PES, and the (main + minor) voice PES registered in the hard disk is selectively output according to the result.

That is, after recording and reproducing a predetermined voice multi-program, the set head of the corresponding reproducible voice is detected according to a user setting, and then the TP attached to the detected set head is selectively extracted, and the MPEG decoder is set according to the user set. Selectively decode any one of the main voice PES, the sub-voice PES, and the (main + minor) voice PES and output it to the audio processor in I ² S format.

Then, the channel matrix of the audio processor and the predetermined output matrix can be output to the outside through the speaker through a predetermined switching matrix. To help.

As described above, the present invention sets the recording start and end time index information of the audio multiple program according to the recording command, and separately sets the recording sequence for each unit transmission packet TP in which predetermined video PES and audio PES are combined. After adding different time stamps, the time stamp is determined whether or not the time stamp is identical to the set recording start or end time index information according to a predetermined program play command input from the outside. In the same case, the user is notified of the fact so that any one of the multiplexed voices can be set according to user selection.

As described in detail above, the method of confirming voice multiplexing of a recorded program according to the present invention enables a user to inform whether a recorded program is voice multicasting before playback, thereby reproducing a recorded voice multiplex program. Through this, you can choose one of main voice, sub voice or (main + minor) voice as you want, so that you can get more convenient and various listening environment.

Although the invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the invention, and such modifications and variations belong to the appended claims.
