DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) Configuration and Overall Operation of First Embodiment First, a recording / reproducing apparatus according to the present invention can be applied to an HDD recording / reproducing apparatus as shown in FIG. The HDD recording / reproducing apparatus according to the first embodiment of the present invention records and reproduces desired data such as a still image, a moving image, audio, music, and a sub-picture on a track.

Specifically, a recording magnetic field is formed on the disk 1 by the magnetic head 2 to record and reproduce data on the disk 1. Data to be recorded / reproduced is composed of sectors. This one sector is 204
Between the 8-byte data and the corresponding address data, etc.
It consists of a total of 2064 bytes. One ECC block (ECC: error correction) is composed of 16 sectors.

For example, an operation unit 4 (KEY) such as a remote controller issues a recording / reproducing command in response to a user operation. System controller 5 (S
YSTEM CONT) determines the command from the operation unit 4 and determines the signal processing unit 6 and the servo processor 7 (SER
VO) and the switch (SW) 12 are controlled.

The preamplifier 8 (PAMP) generates a reproduction signal and a servo signal based on the reproduction output read by the magnetic head 2. The servo processor 7 generates a tracking signal based on the servo signal formed by the preamplifier 8 and supplies the tracking signal to the driver 3. The driver 3 controls the tracking by driving the actuator of the magnetic head 2 based on the tracking signal.

Such a magnetic head 2 → preamplifier 8 →
The tracking of the magnetic head 2 is servo-controlled by the flow of each signal of the servo processor 7 → the driver 3 → the magnetic head 2. The spindle motor M is provided with a hall element (not shown), and a rotation position signal from the hall element is fed back to the servo processor 7 via the driver 3. The servo processor 7 controls the spindle motor M via the driver 3 at a constant rotation speed based on the speed signal generated from the rotation position signal.

The preamplifier 8 optimizes the frequency characteristics of the reproduced signal with an equalizer, and pulls in the PLL circuit.
Further, the preamplifier 8 has a jitter generation circuit that generates a jitter value based on a comparison between a bit clock of a PLL circuit and a time axis of data. The system controller 5 converts the jitter value generated by the jitter generation circuit into an A /
It is configured to D-convert and capture, and change the correction amount of the waveform correction circuit during recording based on the jitter value.

The preamplifier 8 supplies a disk speed signal generated by the PLL circuit to the servo processor 7, and controls the rotation of the disk 1 at a constant speed via the spindle motor M based on the speed signal.

The signal processing circuit 6 converts a reproduced signal output from the preamplifier 8 into a digital signal, synchronously detects the digital signal, and converts the reproduced output into a recording signal when the signal is recorded on the disk 1. Decoding is performed, and error correction processing is performed in units of one ECC block to obtain an address signal and a data signal of each sector. Signal processing circuit 6
A track buffer 9 (TB), which is, for example, a 64 Mbit DRAM, is connected to and stores the address signal and the data signal, and absorbs the time axis of the variable transfer rate of the video signal.

The signal read from the track buffer 9 is cut out from the video signal to be reproduced, excluding the control information and the additional information, and the encoder / decoder 10 (AV END)
EC). The AV ENDEC 10 temporarily stores this signal in the buffer memory 11, which is, for example, a 64 Mbit DRAM, and reads the signal as appropriate, and records the recording mode (described later) in which the signal is recorded on the
Detection is performed based on the control data recorded above, and the speed of expanding the signal is determined in accordance with the detected recording mode. And according to this elongation speed,
An audio signal and a video signal are decompressed from MPEG2 data of one GOP (group of pictures) composed of a plurality of ECC blocks, separated into an audio signal and a video signal, and converted into an analog signal by a D / A converter (not shown) and output. .

An audio signal (A) output from the AV ENDEC 10 is input to an audio amplifier 13 via a terminal A1 of a switch (SW) 12, amplified to a predetermined signal level, and then reproduced by a speaker 14. On the other hand, the video signal (V) output from the AV ENDEC 10 is transmitted through the terminal A2 of the switch (SW) 12 to the NT level.
A monitor or a television receiver (TV) 16 which is inputted to the SC encoder 15 and converted into a signal in conformity with a standard television signal of the NTSC system, and which is a display.
Supplied and displayed. In addition, as will be described later, the temporarily stored content icon is also supplied to the monitor or the television receiver (TV) 16 as a display and displayed.

A digital broadcast wave signal received by the antenna 17 and a signal input to the Internet or the cable TV network 20 are input in the following packet units as shown in FIG. Control information of video information A Control information for controlling reproduction Specifications of video information A Title of video, copyright information Copy management information Permission prohibited (recording prohibited, OK only once,
(Predetermined number of times OK) Transmitted date and time Additional information of video information A Title of video information A Information source information Transmission channel, information provider, address URL, transmitted date and time Video information Content code, type, individual number, main sub-picture, Short-time video Protagonist, lead, competition, actor, original, director, music, production Copyright information Copy permission prohibited (recording prohibited, only once OK)

A digital broadcast wave signal received by the antenna 17 is received by a TV tuner 18. A packet containing an audio signal and a video signal compressed by MPEG or the like is sent to one input terminal of an AV input converter 19. On the other hand, the audio signal / video signal selectively received by the cable converter (modem) 21 connected to the Internet or the cable TV network 20 is supplied to the other input terminal of the AV input converter 19. The AV input converter 19 converts the packet signal (audio signal / video signal) from the TV tuner 18 and the packet signal (audio signal / video signal) from the cable converter (modem) 21 into HD.
A format conversion for converting into a format required for recording on D is performed, and the format is selectively switched and supplied to the terminals (terminals B1 and B2) of the switch 12 and also supplied to the AV ENDEC 10. .

The switch (SW) 12 is configured to be selectively switched by a control signal supplied from the system controller 5, and a terminal is used when reproducing an audio signal / video signal reproduced by the DISC 1 during normal reproduction. A1 and terminal A2 are selectively switched, and the antenna 17
In order to view the broadcast wave signal received by the terminal or the signal of the Internet or the cable TV network, the terminal B1 and the terminal B2 are selectively switched.

(B) Recording Operation In the above-described HDD recording / reproducing apparatus according to the embodiment of the present invention, for example, the transfer rate of a transmitted packet is 8 Mb.
High image quality mode that can record ps signal for 2 hours, intermediate image quality mode that can record 4 Mbps signal for 4 hours, and normal image mode that can record 2 Mbps signal for 8 hours. Recording at different transfer rates.

For this reason, the system controller 5 indicates the recordable area and the non-recordable area on the disk 1 corresponding to each recording mode (each transfer rate) prior to the recording control in order to show the user the material for selecting the recording mode. The available area is determined, and the recording time and / or capacity in each recording mode are displayed. Then, data is recorded in the recordable area corresponding to the recording mode selected by the user based on this display.

Specifically, when displaying the recording time and / or capacity in each recording mode, the system controller 5 starts the data area (recorded area) recorded in the management area of the disk 1. The address and the end address are read out to the track buffer 9 and the start address and the end address of the free area are specified from the interval between the start address and the end address of the data area (= the capacity of the free area). Is calculated and stored together with the position.
This is repeated to calculate the capacities of all free areas and store them together with the position information.

Next, each of 2, 4, 8M to be recorded
In the case of three types of transfer rates of bps, it is calculated whether or not the capacity of each independent free area enables continuous recording or continuous reproduction at each transfer rate.

Regarding the seek time, the disk
Because of the control, the address difference between the addresses is calculated, and the number of track movements based on the address difference is obtained by referring to a seek table stored in the ROM of the system controller 5. By performing a predetermined coefficient operation on this, a seek time is calculated. Alternatively, the seek time may be calculated as a predetermined constant value by the device.

Next, the type of signal to be recorded is selected, the recording mode (transfer rate) is set, and the start of recording is instructed.
Is the recording mode (transfer rate) set by the user
Is set to AV ENDEC10. Further, control is performed on the disk 1 via the magnetic head 2 to fetch an address signal detected by an address reproducing circuit in the magnetic head 2. The system controller 5 controls the movement of the magnetic head 2 to the sector where recording is to be performed via the servo processor 7 and the driver 3 based on the address signal, and controls the magnetic head 2 in a standby state at this address.

The AV ENDEC 10 controls the writing / reading of the buffer memory 11 and converts the video signal (and the audio signal) to be recorded in MPEG units on a GOP basis.
After compression processing, the “FUL” of the track buffer 9 is
L "and" EMPTY ". The values of “FULL” and “EMPTY” are values indicating the upper limit value and the lower limit value of the data written to the track buffer 9, respectively.

The signal processing circuit 6 has an AV ENDEC 10
And writes the data compressed in the track buffer 9 for each predetermined recording unit.
At the timing when the data amount of the data written to the buffer reaches the value of "FULL", the reading of the data written to the track buffer 9 is started, a sector address, a sync signal, an error correction code are added, and the ECC block unit is added. Data. Then, this data is, for example, “25
Mbps "at the transfer rate.

Until the data read from the track buffer 9 is supplied, the magnetic head 2 is controlled to be in a standby state (kick waiting state) on the track to be recorded, and the data is supplied. Then, the standby state is released, and data is recorded on the target recording track.

Next, while the data is being read from the track buffer 9, the AV ENDEC 10
The data transfer rate of the written data is, for example, 8 Mbps, whereas the transfer rate of the read data is 25 Mbps. For this reason, the reading speed is faster than the writing speed to the track buffer 9, so that even when the writing is performed, the data amount of the data stored in the track buffer 9 gradually decreases, and the "EMPTY"".

The system controller 5 determines that the data amount of the data written in the track buffer 9 is "EMPT
When the value becomes "Y", reading of data from the track buffer 9 is stopped, and the magnetic head 2 is also controlled to a standby state (a kick waiting state) on the next track to be recorded. Then, by performing data writing in a state where the reading is not performed, the data reading is restarted at the timing when the data amount of the track buffer 9 becomes the value of “EMPTY”. The system controller 5 controls the recording of data while performing such writing and reading control with respect to the track buffer 9 so that the continuity of the input data can be maintained while performing intermittent recording on the disk 1. We record after securing.

(C) Reproduction Operation In the reproduction mode, the system controller 5 intermittently records data based on the start address and end address of the data area (recorded area) recorded in the management area on the disk 1. The magnetic head 2 is moved and reproduced so as to retrieve the recording position of the data which has been recorded, and reproduce the data in order.

The system controller 5 detects a compression rate of the reproduced signal, which is recorded in the control data of the video signal when the data is recorded, and adjusts the compression rate so as to correspond to the compression rate. , "FU
"LL" and "EMPTY" are set in the track buffer 9, respectively.

The data reproduced from the disk 1 is transferred to the track buffer 9 at the transfer rate of 25 Mbps and written. The system controller 5 monitors the remaining capacity of the storage capacity of the track buffer 9, and transfers the data written to the track buffer 9 at the timing when the remaining capacity becomes “EMPTY” at a transfer rate at the time of recording the data. Read control is performed, and this is
Supply to C10.

Further, at the timing when the remaining amount becomes "FULL", the magnetic head 2 is put in a standby state (a state of waiting for a kick).
And only the control of reading data from the track buffer 9 is performed. Then, by reading only data from the track buffer 9, the remaining amount becomes “EMPT”.
At the timing of "Y", the reproduction control of the optical head 2 is performed so that the reproduction of the data is restarted. As a result, while the data is intermittently reproduced from the disk 1, the data reproduced from the track buffer 9 can be reproduced continuously, and the reproduction with the continuity of the data can be performed.

The AV ENDEC 10 separates and forms video data and audio data by subjecting the data read from the track buffer 9 to an MPEG expansion process while controlling the writing / reading of the data to / from the buffer memory 11. Output via a D / A converter (not shown). Thereby, continuous video and audio recorded on the disc 1 can be viewed via the television receiver 16, for example.

Here, the processing of the embodiment of the present invention will be described with reference to the flowchart shown in FIG. As necessary, video information A, control information of the video information A, and additional information of the video information A are input as information input from outside (step 10).
0).

Then, it is determined whether or not it is in the reproduction instruction state (step 110). When it is in the reproduction instruction state (in the case of Y in step 100), only the video information A is extracted and reproduced from the AV ENDEC 10 according to the packet information. At that time, the control information of the video information A is read and decoded, and once reproduced in the temporary storage means (here, the HDD) according to the copy management information which is the control information of the video information A, The date of reproduction is recorded and used as a history for future management (step 120).

Next, when it is not a reproduction instruction (step 11)
0 and N), for example, when the user leaves the seat due to a telephone call during playback or the like, it is determined whether or not the input information A is in a temporary storage instruction state (step 130) and temporarily stored in the HDD. At the time of storage, the history of the recording / reproduction control information of the video information A is searched from the recording / reproduction device HDD, and it is determined from the search result whether temporary storage is possible.
Investigate the history information as to whether or not the playback that was left at the time of recording was performed as control information of. (Step 14
0).

If temporary storage is possible (Y in step 140)
), The video information A, the control information of the video information A, and the additional information of the video information A are recorded in predetermined areas of the temporary storage means (here, HDD). At this time, if the period in which this information is reproduced is limited by the copy management information, the time information is simultaneously recorded by the date and time means which this apparatus has as a function.
Starts time management (step 150).

Next, the additional information of the recorded video information A is read out (the information is read out of the TB9 even if the information is stored in the HDD).
This is interpreted, and the title and thumbnails of the content A information and the like are displayed as additional information on the display unit 16 via the AV ENDEC 10 as shown in FIG. And that the information to be reproduced exists in the HDD. When the number of the temporarily stored contents increases, a plurality of thumbnails cannot be displayed on the screen. Therefore, the size may be reduced as shown in a list and buttons as shown in FIG. 3 (step 160). The lower left part of FIG. 3 shows title information, input channel, recorded date and time, content providing maker information (commercial) as thumbnails showing a still image or the like of a typical screen of one content. By displaying the content, the content sending side can earn profits from commercials, so that the amount charged for the content can be reduced.)
Etc. This thumbnail is linked to the video information as the main information, and by selecting this information, the video information as the main information can be reproduced. Since the thumbnail information increases as the recording operation is continued, if the number of thumbnail information increases beyond a predetermined screen so as not to deviate from the display screen, as shown in the lower right of FIG. Change to a list of days etc. Thus, it is possible to manage a large amount of information during reproduction.

Next, when the content A recorded on the HDD is reproduced by inputting the key 4 or the icon input position with a mouse or a remote controller or the like or by playing or releasing the pause, the content to be reproduced by the icon or the like is input by the user. Is selected (step 170), it is determined whether or not the playback is instructed (step 180), and the time when the A information is recorded is compared with the current time. A comparison is made as to whether or not the number of times of reproduction is reached (step 190). If the number is not exceeded, that is, if the reproduction is permitted (N in step 190), only the video information A on the HDD is read out and sent to the monitor 16 via the AV ENDEC 10. Display reproduction is performed, and after reproduction, the control information of the video information A on the HDD is updated to record when reproduction was performed once (step 200). ).

If the reproduction is prohibited only once or a predetermined number of times and the reproduction is prohibited (Y in step 190), the control information of the video information A on the HDD is changed to prohibition, and And the title, thumbnail, etc. of the displayed additional information are deleted from the monitor.

In this case, if the reproduction is not performed after the period to be reproduced, there is a problem that the information cannot be viewed in spite of the paid information. Do not delete the information title, thumbnail, etc. from the monitor, and display to the user that the time limit has expired, and display the necessary information source signal to view information A again. In this case, it is possible to maintain the viewing right of the busy user by making it possible to retrieve the information A again via a communication line such as the Internet (step 210).

The present invention is not limited to the above-described embodiment described as an example. Even if the present invention is not limited to the above-described embodiment, it may be designed without departing from the technical idea of the present invention. Needless to say, various changes can be made according to the conditions.
