Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of distributing a music program in digital multi-channel broadcasting and a receiving / reproducing apparatus for the broadcasting. The present invention relates to a distribution method and a reception / playback apparatus for synchronizing and displaying on a display.

2. Description of the Related Art Currently, a CS digital multi-channel broadcasting system using a communication satellite (hereinafter, CS) as a relay station is operating as digital multi-channel broadcasting. Programs broadcast by this system are converted into digital data by a data encoding and compression method specified by MPEG2. In addition to video data and audio data, various data such as characters and program data are added to the program as needed. These data groups are time-division multiplexed to obtain a bit stream for one program. Furthermore, a plurality of programs are bundled and channel-multiplexed, so that about 4 to 8 channels of TV programs can be distributed per transponder. Therefore, the TV program and the radio program can be simultaneously distributed in 100 or more channels in one CS.

[0003] Among CS digital multi-channel broadcasting channels, there are many music specialty channels that handle concerts and BGM. Of course, there are special karaoke channels that reflect the recent karaoke boom. In this karaoke broadcast, an accompaniment music in the karaoke music and a mood video including lyrics are broadcast as a TV program.

[0004] In order to receive such CS digital multi-channel broadcasting and reproduce the video and audio of the program, IRD
(Integrated receiving and decoding device) is provided. The IRD reproduces a video signal and an audio signal of a program by processing broadcast data in a broadcast wave captured by a parabolic antenna or the like. The video and audio of the program are output by an audiovisual (AV) device connected to the audio / video output unit of the IRD.

[0005]

In karaoke broadcasting in CS digital multi-channel broadcasting, karaoke can be enjoyed at home without going to the karaoke venue.
Also, karaoke enthusiasts can practice in advance in preparation for a "real" performance at a karaoke venue. However, unlike a karaoke device that allows the user to freely select a requested song, the song desired by the viewer is rarely broadcast at the exact timing when he or she wants to sing. Furthermore, from the viewpoint of practicing or learning music, karaoke enthusiasts would like to listen to a model singing by a singer at the same time, rather than karaoke broadcasting. Certainly, CS
In digital multi-channel broadcasting, a huge number of music performances are broadcast in parallel on different channels for each genre, so that a desired music can be viewed only by waiting for a relatively short time.

However, there is a decisive problem that lyrics are not displayed in music programs other than karaoke broadcasting. In order to memorize a certain song, it is essential to memorize the lyrics. Of course, not only karaoke enthusiasts but also other viewers can get acquainted with the music if the program music has lyrics. If it is a TV program, the broadcaster can record it as a video with lyrics when producing the program,
That is not possible with radio broadcasting.

Therefore, the present invention provides a music program distribution method capable of outputting a lyrics image synchronized with the performance of a program tune broadcast in a music program in digital multi-channel broadcasting to a display, and a reception / playback apparatus therefor.

BEST MODE FOR CARRYING OUT THE INVENTION

=== Configuration of Digital Multi-Channel Broadcasting System === A CS digital multi-channel broadcasting system will be described as an embodiment of the digital multi-channel broadcasting system including the music program distribution method and the reception / reproduction device according to the present invention. FIG. 1 is a diagram showing the basic structure of the broadcasting station 1 and the CS.
10 and a receiving / reproducing device 20. The broadcasting station 1 and the receiving / reproducing apparatus 20 are connected by a telephone line 100 at an appropriate time. These basic configurations are exactly the same as conventional CS digital multi-channel broadcasting.

=== First Embodiment === A music program distribution method according to the first invention and a receiving / reproducing apparatus according to the second invention will be described according to the first embodiment described below. FIG. 2 shows an example of a time-series structure for each multiplexed data broadcast by the music program distribution method according to the first invention. The multiplexed data includes lyrics rendering data and time data in addition to the program audio data of the music program. Of course, in the case of TV broadcasting, the video of the program is multiplexed as MPEG2 video data.

The lyrics rendering data is data relating to the lyrics of the program music broadcasted in the music program, and includes a coded lyrics character string, a display layout, a lyrics rendering sequence, a character string deletion instruction, and a singing timing instruction. .

The lyric character string is obtained by arranging character codes corresponding to the lyric characters in the chronological order of music performance. Each character has an attribute such as a color, a size, or a type (such as ruby). The display layout specifies the position of the lyric character displayed on the display by the receiving and reproducing apparatus described later. The lyrics rendering sequence shows the order and the rendering time when the lyrics character string is divided into appropriate phrases and displayed on the display one after another. The character string deletion instruction specifies a time at which a character string sequentially displayed on the display is deleted according to the lyrics rendering sequence. The song timing instruction designates the start and end times of the color change for each character.

The lyrics rendering data including these pieces of information starts to be transmitted before the program music corresponding to the data is broadcast. Then, the data is transmitted collectively as a continuous data stream for one music piece. In this embodiment,
Lyrics rendering data corresponding to a certain program music starts to be transmitted at the end of the previous music. If the entire data stream cannot be transmitted between songs, the end of the stream overlaps the broadcast time of the program song. Of course, the transmission may be started before the end of the previous song.

The time data is data describing the elapsed playing time based on the broadcast start time of the program music. During the broadcasting of the program music, the elapsed time is recorded at intervals of a sufficiently short interval. Continue sending.

After the multiplexed program data is added with scramble information as required, the multiplexed program data is channel-multiplexed for transmission in one carrier frequency band together with the multiplexed data of another channel, and QPSK-modulated and transmitted. .

The broadcast wave transmitted in this manner is captured by a parabolic antenna or the like and converted into an intermediate frequency (IF) signal. This IF signal is transmitted to a receiving and reproducing device (hereinafter, IR
D). FIG. 3 shows a configuration diagram in an embodiment of the IRD for receiving the above-mentioned music program broadcast. The IF signal processing of the IRD 20 will be described with reference to FIG.

The central control unit 21 has a CPU, a RAM,
Microcomputer including ROM and font database 2
2 and a timer 23 and the like. The font database 22 includes a kanji ROM and stores character fonts as bitmap data. Timer 23
Performs time management according to the time data in the multiplexed data, and counts the elapsed playing time of the program music. Central control unit 2
1 and each component are appropriately connected by a control bus 34 and a data bus 35. Note that the IC card 30 set in the IC card interface unit 29 has a CS
Data related to the accounting system and the descrambling system, such as digital multi-channel broadcast viewing records and descrambling information, are written. Then, at an appropriate communication opportunity, data communication is performed with the broadcasting station via the modem 34 to transfer recorded contents and the like.

Each component of the IRD 20 performs IF signal processing on the following path under the control of the central control unit 21. Upon receiving a tuning operation input from the remote control transmitter 32 or the operation input unit 31, the central control unit 21 controls the tuning unit 24 to tune to the IF frequency of the carrier including the selected channel, and to control the IF. Let the signal be extracted. The demodulation unit 25
The F signal is QPSK demodulated to extract a channel-multiplexed data stream. The demultiplexing unit 26 separates this data stream as a multiplexed data stream for each channel. Further, a data stream corresponding to the selected channel is taken out, and a descrambling process is performed as necessary. Then, data for each data type is extracted from the multiplexed data for one channel. The program audio data (TV) extracted by the demultiplexer 26
MPEG2 decoding unit 2)
7 is sent. Here, the video signal and the audio signal of the program are reproduced. The reproduced video and audio signals are displayed on the display 4.
0 and the audio amplifier 41 respectively, and the video and audio of the music program are output to the display 40 and the speaker 42.

On the other hand, the lyrics rendering data and the time data extracted by the demultiplexer 26 are sent to the data bus 35, and the central controller 21 receives them. IRD2 according to the present embodiment
No. 0 has a lyrics rendering function of outputting a lyrics image synchronized with the performance of the program music to a display by the central control unit 21 appropriately processing the lyrics rendering data and time data. Hereinafter, signal processing in this function will be described.

Upon receiving the lyrics rendering data sent from the demultiplexing unit 26, the central control unit 21
This data is stored in the AM. Then, it prepares for the start of the performance of the program music. When the performance of the program music starts, time data is sent. The timer 23 keeps track of the time data to count the performance time. The central control unit 21 processes the lyrics rendering data in synchronization with the performance time series of the program music by comparing the performance time with the time information described in the lyrics rendering data. When the display time of the first character string comes according to the lyrics rendering sequence, font data corresponding to the code of each character in this character string is extracted from the font database 22. Then, a lyrics image is generated by expanding the font data of each character in the video RAM 33 according to the attributes and the display layout in a bitmap manner. The lyrics image is output to the display 40 via the video control unit 28. If the music program is a TV broadcast, the video control unit 28
2 superimposes the lyrics image on the TV video signal from the decoding unit 27 and displays the video signal on the display 4
Output to 0. With the progress of the performance, when a certain character reaches the singing timing, the color change speed is calculated from the singing timing instruction information and the displayed character width, and gradually from the start to the end of the singing timing instruction at equal time intervals. Lyric images for which the color-change wipe display is completed are sequentially bitmap-developed in the video RAM 33. Then, when the timing for erasing the character string comes, the data in the video RAM 33 is erased. In the same manner, data after the next step in the lyrics rendering sequence is processed.

The display of the character string and the timing of the singing timing may be displayed a certain time earlier than the designated time in consideration of the simplicity of the singer watching the lyrics.
Similarly, the character string may be erased at a later timing by a certain period of time with a lingering finish. Alternatively, the time described in the lyrics rendering data may be set earlier or later from the beginning.

=== Second Embodiment == A music program distribution method according to the third invention and a reception / playback apparatus according to the fourth invention will be described according to a second embodiment described below. FIG. 4 shows an example of a time-series structure for each data multiplexed with broadcast data in the third invention. The lyrics rendering data for one song is divided into a plurality of lyrics rendering data blocks. This data block corresponds to each step of the lyrics rendering sequence, and includes information on the lyrics character string, display layout, singing timing instruction, and character string erasing instruction in that step. These lyrics rendering data blocks are sequentially and intermittently transmitted in time series. The transmission timing of each lyrics rendering data block
It is set at the time when the character string included in the data block matches the performance time series of the program music. Also in this case, the transmission timing may be appropriately advanced in consideration of the singing timing of the singer.

The IRD for receiving the music program broadcast thus distributed is almost the same in structure as the IRD 20 shown in the first embodiment. However, in this embodiment, the data processing method is different. The data processing will be described according to the reference numerals shown in FIG. The lyrics rendering data extracted by the demultiplexing unit 26 is intermittently transferred to the central control unit 21 as a data block in chronological order. Upon receiving the data block, the central control unit 21 stores the information of the singing timing instruction and the character string erasing instruction included in the data block in the RAM, and stores the lyrics character string included in the data block in accordance with the attribute and the display layout. Immediately, control for displaying on the display 40 is performed. Then, while successively comparing the performance elapsed time measured by the timer 23 with the time described in the lyrics rendering data block, it waits for a timing to process the information of the singing timing instruction or the character string deletion instruction. When the timing of the information processing comes, the control of the color change and the control of the character string deletion are performed by the same processing as in the first embodiment. When the next lyrics rendering data block is transmitted, the same processing is performed again.

Although the time data is transmitted as one of the multiplexed data as in the first embodiment, the time at the time of transmission may be described in the lyrics rendering data block. In this case, until the next data block is received, the timer 23 of the IRD 20 measures the elapsed playing time by the internal clock.

=== Third Embodiment === A music program distribution method according to the fifth invention and a reception / playback apparatus according to the sixth invention will be described in accordance with the following third embodiment. FIG. 5 shows an example of a time-series structure of multiplexed data according to the fifth invention. As in the second embodiment,
The lyrics rendering data for one song is divided into a plurality of lyrics rendering data blocks corresponding to each step of the lyrics rendering sequence, and is intermittently sent out. However, the first and second
Unlike the embodiment, the multiplexed data does not include time data.

The lyrics rendering data block includes a lyrics character string, a display layout, and an identification code of the data block. Note that the identification code may be appropriately set, for example, by assigning the identification code to each character string displayed in two columns without assigning it to each data block. The information of the singing timing instruction and the character string erasing instruction are sequentially transmitted at appropriate timing before the next lyric rendering data block is transmitted. There is no description of the time in these pieces of information, the singing timing instruction information describes the own data ID, the character to be sung and the color changing speed, and the character string erasing instruction information includes the own data ID. The identification code of the lyrics rendering data block or character string to be deleted is described. For example, in the case of a singing timing instruction, the transmission timing of these data is set to coincide with the time when a certain character reaches the singing timing.

Also in this embodiment, the lyric rendering data block, the singing timing instruction information and the character string erasing instruction information may be transmitted earlier or later in consideration of the singing voice of the singer. The character string deletion instruction is 2
It may be inserted twice between sending out the lyrics rendering data block, for example, in the case where the lyrics displayed in columns are deleted for each column.

The IRD for receiving the music program broadcast thus distributed is substantially the same in structure as the IRD 20 shown in the first and second embodiments. However, in this embodiment, the central processing unit 21 does not need to include the timer 23 that functions as described above. Of course, the data processing method is also different. Hereinafter, the IRD in the present embodiment will be described.
(The reference numerals used in the description are based on FIG. 3).

The demultiplexing unit 26 extracts program audio (video) data, lyrics rendering data blocks, singing timing instruction information, and character string deletion instruction information from the multiplexed data for one channel. The lyrics rendering data block, the singing timing instruction information, and the character string erasing instruction information are sequentially transferred to the central control unit 21 in accordance with the respective transmission time series.
Upon receiving the lyrics rendering data block, the central control unit 21 immediately displays the lyrics character string included in the data block on the display 40 as a lyrics image according to the attributes and the display layout. When receiving the singing timing instruction information, the lyric image in which the color specified by the information is changed at the specified speed is sequentially output to the video R.
Bitmap development is performed on AM33. When the color change is completed, it waits for the transmission of the next singing time instruction information. When a character string erasure instruction is received, the lyrics image data block or the lyric image corresponding to the character string specified by the information is erased from the video RAM 33. In this way,
In accordance with the lyrics rendering data block, the singing timing instruction information and the character string erasure instruction information corresponding to the data block, the lyrics image generation processing and display control are performed.

The identification code may not be assigned to the lyrics rendering data block, and the character string erasure information may be information in which the character code of the corresponding lyrics rendering data block is a space (blank character). In this case, the character string is erased on the display by replacing each character with a space.

=== Others === In the above-described first and second embodiments, the time data is transmitted at a sufficiently short time interval. In this case, the timer of the IRD acquires the performance elapsed time based on the time data at the time of reception, and then measures the time by the internal clock or the like by itself until the next time data is received.

Alternatively, instead of multiplexing the time data as one independent data, the MPEG2-Sys employed in the CS digital multi-channel broadcasting system is used.
The performance elapsed time may be measured by using a multiplex data structure defined in tems. in this way,
Reference time information (PCR) in the header of TS (Transport Stream) and PE in each data
S (Packetized Elementary S
presentation time information (PTS) in the header section of the stream)
(This technology is not described because it is used in the current CS digital multi-channel broadcasting system.)

The IRD sequentially calibrates the internal clock according to the PCR. If the rendering time of the lyric character in the lyrics rendering data, the singing timing instruction time, and the like are described in PTS, the appropriate data can be processed at the appropriate time by successively comparing the PTS with the internal clock. it can. Alternatively, the broadcast start time of the program music may be transmitted in advance, or information indicating that may be transmitted at the moment of the broadcast start. In this case, if the IRD calculates the relative time with respect to the broadcast start time of the program music based on the PCR, the elapsed playing time can be measured. In this method, for example, when a channel is switched to a channel broadcast on another carrier during reception of a music program, the internal clock of the IRD is calibrated according to the PCR of the channel to which the channel has been switched. In such a case, it is necessary to separately prepare an internal clock for the lyrics display processing, or not to calibrate the internal clock until the program music ends.
