Description

  The present invention relates to a data reproducing apparatus that reproduces data recorded on a recording medium, and more particularly to a data reproducing apparatus that speeds up access to a target address.

  A conventional data reproduction device displays video on a television connected to the data reproduction device by reproducing video data of a television broadcast recorded in advance on a hard disk device (hereinafter referred to as HDD), and audio. Is output (for example, see Patent Document 1). In such a conventional data reproducing apparatus, in general, a physical address to be reproduced is advanced to a desired physical address by pressing a fast forward button / fast reverse button provided in an operation unit or a remote control unit (hereinafter referred to as a remote control unit). / Regress data can be played back.

In addition, some conventional data reproducing apparatuses are provided with a CF (commercial film) skip button on the operation unit or the remote control unit. The processing by the CF skip button is generally set so as to skip the reproduction time of the video data by about 30 seconds or 1 minute by one press operation. Therefore, when the program changes to advertisement playback during program playback, the continuation of the program can be quickly played back by skipping the advertisement playback by pressing the CF skip button a plurality of times. The CF skip button may be referred to as a CM (commercial message) skip button depending on the model.

  However, in the conventional data reproducing apparatus, in the fast forward / reverse process, a series of images is doubled, quadrupled,..., Normal reproduction speed until an instruction to cancel the process is given. Displayed at a speed of 10 times. Therefore, the slower the processing speed, the longer it takes to access a relatively distant physical address. On the other hand, the faster the processing speed, the faster the flow of the displayed image, making it difficult for the user to see it. Therefore, there is a problem that it is difficult to easily and accurately access a desired physical address because an instruction to cancel the process is not given at an appropriate timing.

  Further, unlike the fast-forward process, the operation using the CF skip button can skip the physical address for reproducing the video data. However, the skip process takes about 30 seconds or 1 minute in time, so the physical address is relatively remote. It is not practical to apply as a skip process to an address.

  The present invention has been made in view of such a problem, and an object of the present invention is to calculate an equally divided address corresponding to a time obtained by equally dividing the total reproduction time of data and to skip an address for reproducing the data. An object of the present invention is to provide a data reproducing apparatus capable of easily and quickly accessing a desired address by adopting a configuration in which data is reproduced from the address skipped in the unit of the equally divided address every time a skip instruction is received. .

An object of the present invention is to provide a data reproducing apparatus that can be improved.

  Another object of the present invention is to count the number of times a skip instruction / reverse skip instruction is received, or to count when a skip instruction / reverse skip instruction is received by inputting a numerical value and a skip instruction / reverse skip instruction is received. Access to a desired address can be further accelerated by adopting a configuration in which data is reproduced from the address that is skipped / reversely skipped to the calculated equally divided address only the number of times or the same number as the input numerical value. An object of the present invention is to provide a data reproducing apparatus capable of performing the above.

  Another object of the present invention is to provide a data reproducing apparatus that can improve convenience by setting an n value that divides the total reproduction time of data into n.

  Another object of the present invention is to set an interval for skipping an address for reproducing data and to reproduce data from an address skipped in the set interval unit every time the skip instruction is received. It is an object of the present invention to provide a data reproducing apparatus that can easily and quickly access the addresses.

  Another object of the present invention is to set an interval for reverse-skipping an address for reproducing data and to reproduce data from an address that is reverse-skipped in a set interval unit each time the reverse skip instruction is received. An object of the present invention is to provide a data reproducing apparatus capable of improving operability.

  Another object of the present invention is set when the number of skip instructions / reverse skip instructions received is counted, or when a skip instruction / reverse skip instruction is received by inputting a numerical value and a skip instruction / reverse skip instruction is received. Data that can further speed up access to a desired address by reproducing data from an address that has been skipped / reversely skipped by an interval that is the result of multiplying the interval by the number of times counted or an input numerical value To provide a playback device.

  Another object of the present invention is that data is reproduced from an address corresponding to a time obtained by dividing a reproduction time of an address section to be reproduced every time a skip instruction is received, so that a desired address can be simply and easily obtained. An object of the present invention is to provide a data reproducing apparatus that can be accessed at high speed.

  Another object of the present invention corresponds to a time obtained by dividing the reproduction time from the recording start address to the address being reproduced or the address at which reproduction was suspended, every time a reverse skip instruction is received during data reproduction or reproduction pause. An object of the present invention is to provide a data reproducing apparatus capable of improving operability by adopting a configuration for reproducing data from an address.

  Still another object of the present invention is to create a graph image that represents the total reproduction time of the data and that can be specified at any point in time, and to specify the specified graph point at any point in the total reproduction time. A data reproducing apparatus that can be accessed not only simply and at high speed, but also accurately by receiving data by reference and reproducing data from an address corresponding to the time point according to the received designation. Is to provide.

  The data reproducing apparatus according to the present invention is required when the data reproducing apparatus for reproducing audio and / or moving picture data recorded on a recording medium continuously reproduces from the data recording start address to the recording end address. A calculation means for calculating an equal division address corresponding to a time obtained by equally dividing the total reproduction time; a skip reception means for accepting a skip instruction for skipping an address at which data is reproduced in a direction in which the data is reproduced; and When the skip receiving unit receives the skip instruction, the skip receiving unit includes a playback unit that skips to the equally divided address calculated by the calculating unit and starts playback.

  In the present invention, an address corresponding to a time obtained by equally dividing the total reproduction time of data is calculated, and a skip instruction is accepted. When a skip instruction is accepted, data is reproduced by skipping to the calculated equally divided address.

  The address here refers to a physical address indicating a physical position on the disk associated with the time stamp and the order in which the data is recorded when the data is recorded on the disk, for example, in an HDD or an optical disk. (Track number and sector (the former also includes the surface number)), the address itself corresponds to the semiconductor memory, and the magnetic tape is a tape that is wound in the forward / reverse direction as the motor rotates. Corresponds to the physical position (the same applies hereinafter).

  For example, when the total reproduction time of data is 60 minutes and the total reproduction time is divided into 10 equal parts, the time every 6 minutes (excluding the recording end address) from the data recording start address, that is, 6 minutes and 12 minutes 9 addresses corresponding to 48 minutes and 54 minutes are equally divided addresses.

  Therefore, when a skip instruction is accepted in a state where playback has not yet been performed (that is, in a state where data to be played back is selected), an address corresponding to 6 minutes skipped at a stroke rather than from the recording start address. Play data from. In other words, since normal playback is not started once and then skipped, a normal playback start instruction is not required, and the operation is simplified.

  On the other hand, when the skip instruction is received in a state where the address during reproduction after reproduction or the address where reproduction is paused corresponds to, for example, 15 minutes, data is reproduced from the address corresponding to 18 minutes.

  As described above, every time a skip instruction is received, skip reproduction is performed from a nearby equally divided address, so that access to a desired address is simplified and speeded up.

  The data reproducing apparatus according to the present invention further comprises reverse skip accepting means for accepting a reverse skip instruction for reversely skipping an address at which data is reproduced in a direction opposite to the elapsed direction, and the reproducing means includes the reverse skip accepting means. When receiving the reverse skip instruction, the apparatus further comprises means for reverse skipping to the equally divided address calculated by the calculating means and starting reproduction.

  In the present invention, when a reverse skip instruction is received and the reverse skip instruction is received, data is reproduced by performing reverse skip to the calculated equally divided address.

  Therefore, with respect to the data for which the equal reproduction address is calculated by dividing the total reproduction time of 60 minutes into 10 equal parts, the address during reproduction after reproduction or the address where reproduction is paused corresponds to, for example, 45 minutes. When a reverse skip instruction is accepted, data is reproduced from an address corresponding to 42 minutes.

  As described above, every time a reverse skip instruction is received, reverse skip reproduction is performed from a nearby equally divided address, so that operability is improved.

  In the data reproducing apparatus according to the present invention, the data reproducing apparatus further includes a counting unit that counts the number of times the skip receiving unit and the reverse skip receiving unit have received the skip instruction and the reverse skip instruction, respectively, and the reproducing unit includes the skip receiving unit. Alternatively, when the reverse skip receiving unit receives the skip instruction or the reverse skip instruction, the playback is started by skipping or reverse skipping to the equally divided address calculated by the calculation unit by the number counted by the counting unit. It is characterized by being.

  In the present invention, the number of receptions of the skip instruction and the reverse skip instruction is counted. When a skip instruction or reverse skip instruction is received, the data is reproduced by skipping or reverse skipping to the calculated equally divided address by the counted number of times.

  Therefore, if the skip instruction is received five times in succession for the data for which the equal reproduction address is calculated by dividing the total reproduction time of 60 minutes into 10 parts, the recording start address is received. The data is reproduced from the address corresponding to 30 minutes skipped at a stroke instead of from.

  On the other hand, when the skip instruction is received five times in a state where the address during playback or the playback paused after the playback once corresponds to, for example, 15 minutes, the data from the address corresponding to 42 minutes is received. Reproduce.

  In addition, when the reverse skip instruction is received five times in succession in a state where the address during playback or the playback paused after the playback once corresponds to, for example, 45 minutes, the data from the address corresponding to 18 minutes is received. Play.

  As described above, since skip reproduction / reverse skip reproduction is performed from more evenly divided addresses in accordance with the number of times the skip instruction / reverse skip instruction is received, access to a desired address is further accelerated.

  In the data reproducing apparatus according to the present invention, the skip receiving unit and the reverse skip receiving unit are configured to receive the skip instruction and the reverse skip instruction by inputting numerical values, respectively, and the reproducing unit includes the skip receiving unit. Alternatively, when the reverse skip receiving unit receives the skip instruction or the reverse skip instruction, the playback is started by skipping or reverse skipping to the equally divided address calculated by the calculation unit by the number of times corresponding to the input numerical value. It is characterized by being.

  In the present invention, the skip instruction and the reverse skip instruction are received by inputting numerical values. Then, when a skip instruction or reverse skip instruction is accepted, the calculated equal division is the number of times corresponding to the input numerical value, that is, the same number of times as the number of times of accepting the skip instruction and reverse skip instruction described above. Data is reproduced by skipping to the address or reverse skipping.

  Accordingly, since skip reproduction / reverse skip reproduction is performed from more equally spaced addresses according to the input value of the skip instruction / reverse skip instruction, access to a desired address is further speeded up.

  The data reproducing apparatus according to the present invention further comprises setting means for setting an n value for dividing the total reproduction time by n (n is an integer of 2 or more), and the calculating means includes an n value set by the setting means. An equal division address corresponding to a time obtained by dividing the total reproduction time by n is calculated using.

  In the present invention, an n value for dividing the total reproduction time of data by n is set, and an equal division address corresponding to the time obtained by dividing the total reproduction time by n is calculated using the set n value.

  For example, when the n value is fixed without depending on the total reproduction time of data, the interval of the equally divided addresses calculated becomes shorter / longer as the total reproduction time is shorter / longer. The interval is small / large (the skip time is short / long if expressed in time). Further, when the n value is changed according to the total reproduction time of the data, the skip / reverse skip interval is subdivided even if the total reproduction time is relatively long. Thereby, the skip / reverse skip interval according to the purpose, that is, the arrangement position of the equally divided address is appropriately determined, and the convenience is enhanced.

  The data reproduction apparatus according to the present invention is a data reproduction apparatus for reproducing audio and / or moving picture data recorded on a recording medium, and skips an address at which the data is reproduced in the direction of passage of time related to the reproduction of the data. A skip interval setting means for setting an interval to be skipped, a skip reception means for accepting a skip instruction for skipping an address at which data is reproduced in the elapsed direction, and the skip interval setting when the skip acceptance means accepts the skip instruction. And reproduction means for starting reproduction from an address skipped by an interval set by the means.

  In the present invention, an interval for skipping data addresses is set, and a skip instruction is accepted. When a skip instruction is accepted, data is reproduced from an address skipped by a set interval.

  For example, the skip interval is replaced with time, and the time is set to 5 minutes. Therefore, when a skip instruction is accepted in a state where playback has not been performed, data is played back not from the recording start address but from an address corresponding to 5 minutes skipped at once. In other words, since normal playback is not started once and then skipped, a normal playback start instruction is not required, and the operation is simplified.

  On the other hand, when a skip instruction is received in a state where the address during playback or playback paused after being once played is, for example, 15 minutes, data is played back from an address corresponding to 20 minutes.

  As described above, every time a skip instruction is received, skip playback is performed in units of set intervals, so that access to a desired address is simplified and speeded up.

  In addition, in order to set the interval for skipping, for example, when the interval for skipping is fixed without depending on the total reproduction time of data, as the total reproduction time is shorter / longer, a relatively far address (for example, Skipping from the vicinity of the recording start address to the vicinity of the recording end address) is speeded up / slowed down. In addition, when an interval for skipping is set according to the total reproduction time of data, skipping to a relatively distant address can be performed at high speed even if the total reproduction time is relatively long. As a result, the degree of skipping according to the purpose is appropriately determined, and convenience is enhanced.

  In the data reproducing apparatus according to the present invention, reverse skip interval setting means for setting an interval for reversely skipping an address for reproducing data in a direction opposite to the elapsed direction, and an address for reproducing the data in reverse to the elapsed direction. Reverse skip receiving means for receiving a reverse skip instruction for reverse skipping in the direction, and when the reverse skip receiving means receives the reverse skip instruction, the playback means is an interval set by the reverse skip interval setting means. It further has means for starting reproduction from the reverse skipped address.

  In the present invention, an interval for reverse skipping the data address is set, and the reverse skip instruction is accepted. When a reverse skip instruction is received, data is reproduced from an address that is reverse skipped by a set interval.

  For example, the reverse skip interval is replaced with time, and the time is set to 5 minutes. Therefore, when a reverse skip instruction is received in a state where the address during playback or playback paused after being played back is, for example, 45 minutes, data is played back from an address corresponding to 40 minutes.

  As described above, every time a reverse skip instruction is received, reverse skip reproduction is performed in units of set intervals, so that operability is improved.

  In addition, in order to set the interval for reverse skipping, for example, when the interval for reverse skipping is fixed without depending on the total playback time of data, the address is relatively far away as the total playback time is shorter / longer. Skipping (for example, from the vicinity of the recording end address to the vicinity of the recording start address) increases / decreases. Further, when the interval for reverse skip is set according to the total reproduction time of data, reverse skip to a relatively distant address can be performed at high speed even if the total reproduction time is relatively long. Thereby, the degree of reverse skip according to the purpose is appropriately determined, and convenience is enhanced.

  In the data reproducing apparatus according to the present invention, the data reproducing apparatus further includes a counting unit that counts the number of times the skip receiving unit and the reverse skip receiving unit have received the skip instruction and the reverse skip instruction, respectively, and the reproducing unit includes the skip receiving unit. Alternatively, when the reverse skip accepting unit accepts the skip instruction or the reverse skip instruction, the interval set by the skip interval setting unit or the reverse skip interval setting unit is skipped by an interval obtained by multiplying the number of times counted by the counting unit or The reproduction is started from the reverse skipped address.

  In the present invention, the number of receptions of the skip instruction and the reverse skip instruction is counted. Then, when a skip instruction or reverse skip instruction is accepted, an interval resulting from multiplying the set skip interval or reverse skip interval by the counted number (hereinafter referred to as total skip interval or reverse skip total interval) is skipped. Or, data is reproduced from the reverse skipped address.

  For example, the skip interval is replaced with time, and the time is set to 5 minutes. Therefore, when skip instructions are received five times in succession in a state where playback has not been performed, the total skip time is 25 minutes, not from the recording start address, but from the address corresponding to 25 minutes skipped at once. Play the data. In other words, since normal playback is not started once and then skipped, a normal playback start instruction is not required, and the operation is simplified.

  On the other hand, if the skip instruction is received five times in a state where the address during playback or playback paused after being played once is, for example, 15 minutes, the total skip time is 25 minutes. Data is reproduced from an address corresponding to 40 minutes.

  Also, the interval for reverse skip is replaced with time, and the time is set to 5 minutes. Therefore, when the reverse skip instruction is received five times in a state where the address during playback after being played back or the playback paused is 45 minutes, for example, the total reverse skip time is 25 minutes. Therefore, data is reproduced from an address corresponding to 20 minutes.

  As described above, since the skip reproduction / reverse skip reproduction is performed from a more distant address in accordance with the number of times the skip instruction / reverse skip instruction is received, access to a desired address is further speeded up.

  In the data reproducing apparatus according to the present invention, the skip receiving unit and the reverse skip receiving unit are configured to receive the skip instruction and the reverse skip instruction by inputting numerical values, respectively, and the reproducing unit includes the skip receiving unit. Alternatively, when the reverse skip accepting unit accepts the skip instruction or the reverse skip instruction, it skips or reverse skips by the interval obtained by multiplying the interval set by the skip interval setting unit or the reverse skip interval setting unit by the input numerical value. The reproduction is started from the address which has been performed.

  In the present invention, the skip instruction and the reverse skip instruction are received by inputting numerical values. Then, when a skip instruction or reverse skip instruction is accepted, the interval obtained by multiplying the set skip interval or reverse skip interval by the input numerical value, that is, the number of times the skip instruction and reverse skip instruction are received is set. Data is reproduced from addresses skipped or reverse skipped by the same skip total interval or reverse skip total interval as in the case of counting.

  Accordingly, since skip reproduction / reverse skip reproduction is performed from more equally spaced addresses according to the input value of the skip instruction / reverse skip instruction, access to a desired address is further speeded up.

  The data reproduction apparatus according to the present invention is a data reproduction apparatus for reproducing audio and / or moving picture data recorded on a recording medium, and skips an address at which the data is reproduced in the direction of passage of time related to the reproduction of the data. A skip receiving unit that receives a skip instruction to be played, and when the skip receiving unit receives the skip instruction, playback is performed from an address corresponding to a time obtained by dividing the playback time required when the address section to be played back is played back continuously. And a reproduction means for starting the operation.

  In the present invention, a skip instruction is accepted, and when a skip instruction is accepted, data is reproduced from an address corresponding to a time obtained by dividing a reproduction time required for continuously reproducing an address section to be reproduced.

  For example, when a skip instruction is received for data with a total playback time of 60 minutes that has not yet been played back, the address section to be played back is 60 minutes from the address corresponding to 0 minutes (recording start address). This is a section up to the address corresponding to (recording end address), and the playback time required for continuous playback of this section is divided into 30 minutes. Data is reproduced from the address corresponding to the skipped 30 minutes. In other words, since normal playback is not started once and then skipped, a normal playback start instruction is not required, and the operation is simplified.

  On the other hand, for data with a total playback time of 60 minutes, if a skip instruction is accepted in a state where the address during playback after playback once or the paused playback corresponds to, for example, 10 minutes, playback should be performed. The address section is a section from an address corresponding to 10 minutes to an address corresponding to 60 minutes (recording end address), and the playback time required for continuous playback of this section is divided into 35 minutes. Therefore, data is reproduced from the address corresponding to 35 minutes.

  As described above, every time a skip instruction is received, skip playback is performed in units of time divided into two for the playback of the address section to be played back, so that access to a desired address, particularly the latter half of the data, is simple and fast. Turn into.

  The data reproducing apparatus according to the present invention further comprises reverse skip accepting means for accepting a reverse skip instruction for reversely skipping an address at which data is reproduced in a direction opposite to the elapsed direction, wherein the reproducing means is reproducing data or When the reverse skip receiving means receives the reverse skip instruction during playback pause, the playback time required for continuous playback from the recording start address to the address being played back or the address at which playback was paused is divided into two times It further has means for starting reproduction from an address corresponding to.

  In the present invention, when a reverse skip instruction is accepted and a reverse skip instruction is accepted during data reproduction or playback pause, playback is continuously performed from the recording start address to the address being played back or the address at which playback was paused. The data is reproduced from the address corresponding to the time obtained by dividing the reproduction time required in this case.

  Therefore, for a data with a total playback time of 60 minutes, if a reverse skip instruction is received in a state where the address during playback after playback once or the address where playback is paused corresponds to, for example, 40 minutes, recording starts Since the reproduction time required for continuous reproduction from the address to the address being reproduced or the address where reproduction is paused is 20 minutes, data is reproduced from the address corresponding to 20 minutes.

  As described above, every time a reverse skip instruction is received during playback or playback pause, reverse skip playback is performed in units of two divisions of playback time from the recording start address to the playback address or playback stop address. In particular, the operability of reverse skip playback to the first half address of data is improved.

In order to perform reproduction from the first half address of data without performing normal reproduction start instruction in a state where reproduction has not yet been performed, the skip instruction and the reverse skip instruction may be sequentially performed in this order. For example, when a skip instruction and a reverse skip instruction are received for data with a total playback time of 60 minutes, an address corresponding to 15 minutes (that is, an address of 1/4 = 0 + 1 / 2−1 / 2 ² of the whole) ) To play data.

  The data reproducing apparatus according to the present invention is required when the data reproducing apparatus for reproducing audio and / or moving picture data recorded on a recording medium continuously reproduces from the data recording start address to the recording end address. A creation unit that creates a graph image that represents a total playback time and that can designate an arbitrary time point of the total playback time, and an arbitrary time point of the total playback time based on the graph image created by the creation unit Receiving means for accepting the designation of the above, and reproducing means for starting reproduction from an address corresponding to the time point corresponding to the designation accepted by the accepting means.

  In the present invention, a graph image that represents the total reproduction time of data and can be designated at any time point is created, and designation of any time point of the total reproduction time is accepted based on the created graph image. Then, the data is reproduced from the address corresponding to the time point according to the accepted designation.

  When the created graph image is displayed by, for example, display means for displaying an image, the total reproduction time (overall feeling) of the data is visually presented to the user, and the desired reproduction start time (time) is displayed to the user. Directly specify the address corresponding to. As a result, an address to be skipped / reversely skipped according to the purpose is determined as appropriate, and access to a desired address becomes simple and can be performed at high speed and accurately.

  According to the present invention, skip reproduction from neighboring equally divided addresses can be performed every time a skip instruction is received, so that a desired address can be accessed easily and at high speed. In particular, when skip reproduction is performed based on the data recording start address, a normal reproduction start instruction is not necessary, and the operation can be simplified.

  Further, according to the present invention, every time a reverse skip instruction is received, reverse skip reproduction from a neighboring equally divided address can be performed, so that operability can be improved.

  In addition, according to the present invention, skip playback / reverse skip playback from a more evenly divided address is performed according to the number of skip instructions / reverse skip instructions received or according to the input value of the skip instruction / reverse skip instruction. Therefore, access to a desired address can be further speeded up. In particular, when skip reproduction is performed based on the data recording start address, a normal reproduction start instruction is not necessary, and the operation can be simplified.

  In addition, according to the present invention, by setting an n value that divides the total reproduction time of data by n, it is possible to appropriately determine the arrangement position of the equally divided address according to the purpose, thereby improving convenience. it can.

  Also, according to the present invention, every time a skip instruction is received, skip playback can be performed in units of set intervals, so that a desired address can be accessed simply and at high speed. In particular, when skip reproduction is performed based on the data recording start address, a normal reproduction start instruction is not necessary, and the operation can be simplified. In addition, since the skip interval is set, the degree of skip according to the purpose can be determined as appropriate, and the convenience can be improved.

  Also, according to the present invention, every time a reverse skip instruction is received, reverse skip playback can be performed in units of set intervals, so that operability can be improved. In addition, since the reverse skip interval is set, the degree of reverse skip according to the purpose can be determined as appropriate, and the convenience can be improved.

  Further, according to the present invention, skip playback / reverse skip playback from a more distant address is performed in accordance with the number of times the skip instruction / reverse skip instruction is accepted or in accordance with the input value of the skip instruction / reverse skip instruction. Therefore, access to a desired address can be further speeded up. In particular, when skip reproduction is performed based on the data recording start address, a normal reproduction start instruction is not necessary, and the operation can be simplified.

  Also, according to the present invention, every time a skip instruction is received, skip playback can be performed in units of two divisions of time related to playback of an address section to be played back. And can be accessed at high speed. In particular, when skip reproduction is performed based on the data recording start address, a normal reproduction start instruction is not necessary, and the operation can be simplified.

  In addition, according to the present invention, every time a reverse skip instruction is received during data reproduction or playback pause, the reverse of the time taken to divide the time from playback start address to playback address or playback pause address. Since skip reproduction can be performed, the operability of reverse skip reproduction to the first half address of data can be improved. In addition, in a state where playback is not yet performed, the skip instruction and the reverse skip instruction are sequentially performed in this order, so that playback can be performed from the first half address of the data without performing a normal playback start instruction. .

  Furthermore, according to the present invention, in order to create a graph image that represents the total reproduction time of the data and that can be designated at an arbitrary time point, when the created graph image is displayed on a display means, for example, the user is notified.

  Based on the control of the control unit 1, the recording signal processing unit 9 performs compression coding processing, addition of error correction codes, and formatting on the digital video data input from the A / D conversion unit 9, and then sends it to the HDD 10. Output.

  Under the control of the control unit 1, the HDD 10 records (on a platter) the video data input from the recording signal processing unit 9, and reads the recorded video data. Although the data reproducing apparatus 20 includes the HDD 10, the present invention is not limited to this, and the data reproducing apparatus 20 may include an optical disk drive that records video data on an optical disk (for example, a DVD-R, a DVD-RW, or a DVD-RAM). .

  Based on the control of the control unit 1, the reproduction processing unit 11 performs D / A conversion on the video data read out by the HDD 10, performs D / A conversion, and outputs the analog video data to the external output unit 12. To do. The external output unit 12 is connected to the television 40 and outputs analog video data input from the reproduction processing unit 12 to the television 40 based on the control of the control unit 1. The television 40 displays a video based on the video data input from the external output unit 12 and outputs sound.

  In addition to the control program, the ROM 2 stores various data such as menu data and display screen data in advance. When the menu button 40 of the operation unit 4 or the menu button of the remote control unit 5 is pressed in a state where various processes relating to recording and reproduction of video data are not performed, the control unit 1 displays menu data or a display screen. Data is read from the ROM 2 as appropriate, and the read menu data or display screen data is output to the external output unit 12.

  The menu data includes data for setting scheduled recording information, and when a skip instruction / reverse skip instruction is received, the forward direction (time direction related to playback) and the reverse direction (the reverse direction to the time direction related to playback) In order to determine the skip time, the skip time setting data for setting the n value for dividing the total reproduction time length of the video data recorded in the HDD 10 into n is included. The display screen data includes data for displaying a list of video data recorded in the HDD 10, data for changing the title name, and the like.

  The external output unit 12 also outputs the menu data or the display screen data input from the control unit 1 to the television 40, so that the television 40 can select a menu screen or a display screen data based on the menu data or the display screen data input from the external output unit 12. Display the display screen.

  FIG. 4 shows an example of a skip time setting menu for determining the skip time characteristic of the first embodiment of the present invention displayed on the television 40. As shown in the drawing, by default, a numerical value “10” is set in the skip time setting menu so that the total reproduction time of the video data is divided into ten equal parts. Since this numerical value is increased and decreased by pressing the channel button 41 of the operation unit 4 or the up / down button or the numeric keypad of the remote control unit 5, an appropriate division value (n value) can be set. And the skip time (skip interval) in the reverse direction can be set arbitrarily.

  The procedure of video data skip playback processing and reverse skip playback processing by the control unit 1 of the data playback device 20 according to Embodiment 1 of the present invention having the above-described configuration will be described with reference to the flowchart of FIG.

  In the following description, it is assumed that the video data to be processed has a total playback time of m minutes and the total playback time is set to be divided equally into n. Accordingly, the equally divided addresses on the platter in the HDD 10 of the video data in this case are (n−1) physical addresses (time stamps) corresponding to the time every m / n minutes excluding the recording end address from the recording start address. And a surface number, a track number, and a sector associated with the order of recording video data.

  First, the control unit 1 inputs a skip button (skip button 48 of the operation unit 4 or a skip button of the remote control unit 5) as an input of a skip playback instruction, or a reverse skip button (reverse skip of the operation unit 4) as an input of a reverse skip playback instruction. It is monitored whether the button 49 or the reverse skip button of the remote control unit 5 is pressed (S11).

  If neither the skip button nor the reverse skip button is pressed in step S11, the control unit 1 continues to monitor pressing of these buttons.

  When the skip button is pressed in step S11, the control unit 1 counts the number of times the skip button is pressed (S12), and then reads out the video data from the HDD 10 by the number of times the skip button is pressed. The processing is performed from the skipped equal division address (physical address), and video data is reproduced from the equal division address (S13).

  Specifically, if the skip button is pressed, for example, once / continuously five times before starting the reproduction of the video data (that is, in a state where the video data to be reproduced is selected and not yet reproduced). The video data is reproduced not from the recording start address but from the equally divided address corresponding to (m / n) / (5 m / n) skipped at once. Accordingly, video from (m / n) minutes / (5 m / n) minutes is displayed on the television 40, and sound is output.

  Also, during playback or playback pause (pause or pause playback when the resume function is in operation), that is, the physical address during playback after playback or paused playback is (2 m / n). ) Minutes and (3 m / n) minutes, when the skip button is pressed once / continuously 5 times, for example, (3 m / n) minutes / (7 m / n) Video data is reproduced from an equally divided address corresponding to minutes. Accordingly, video from (3 m / n) minutes / (7 m / n) minutes is displayed on the television 40, and sound is output.

  Subsequently, the control unit 1 determines whether or not the reproduction of the video data is completed (S14). When it is determined that the reproduction is not completed (S14: NO), the control unit 1 proceeds to step S11 and repeats the subsequent processes while continuing to reproduce the video data. On the other hand, when it determines with reproduction | regeneration having been completed (S14: YES), the control part 1 complete | finishes a process.

  When the reverse skip button is pressed in step S11, the control unit 1 determines whether or not the reverse skip button is pressed before starting the reproduction of the video data (S15).

  If it is determined in step S15 that the reverse skip button has been pressed before starting the reproduction of the video data (S15: YES), the control unit 1 ends the process.

  On the other hand, if it is determined in step S15 that the reverse skip button has not been pressed before the start of reproduction of the video data (S15: NO), the control unit 1 counts the number of times the reverse skip button has been pressed ( Next, reading of the video data from the HDD 10 is performed from the equally divided address that has been reverse skipped by the number of times the reverse skip button has been pressed, and the video data is reproduced from this equally divided address (S17).

  Specifically, the reverse skip button is used in a state where the physical address that has been played once or has been paused and corresponds to a time between (7 m / n) minutes and (8 m / n) minutes, for example, When pressed once / continuously 5 times, video data is reproduced from equally divided addresses corresponding to (7 m / n) / (3 m / n). Accordingly, video from (7 m / n) minutes / (3 m / n) minutes is displayed on the television 40, and sound is output.

  After the process of step S17, the control unit 1 proceeds to step S14 and repeats the subsequent processes.

  In addition, after performing the above skip reproduction (step S13) or reverse skip reproduction (step S17), normal operation of the fast forward button 45 / fast reverse button 43 of the operation unit 4 or the fast forward button / fast reverse button of the remote control unit 5 is performed. Of course, the physical address at which reproduction is started can be finely adjusted by the pressing operation.

  Further, in the present embodiment, the skip playback process and the reverse skip playback process are counted by pressing the skip button and the reverse skip button, and the skip playback and reverse skip playback for each equally divided address unit are performed according to the counted number. However, the present invention is not limited to this, and after pressing the skip button or the reverse skip button, by inputting a numerical value with the numeric keypad of the remote control unit 5, each equally divided address unit according to the input numerical value. The skip reproduction and reverse skip reproduction may be performed.

(Embodiment 2)
The appearance and configuration of the data reproduction apparatus according to the second embodiment of the present invention are the same as those of the first embodiment, and the skip reproduction process and the reverse skip reproduction process are different. This will be described below.

  FIG. 6 shows an example of a skip time setting menu for determining the skip time characteristic of the second embodiment of the present invention displayed on the television 40. As shown in the figure, by default, a numerical value of “5” is set in the skip time setting menu so that the physical address at which video data playback is started is skipped / reversely skipped at 5-minute intervals. Since this numerical value is changed by increasing / decreasing by pressing the channel button 41 of the operation unit 4 or the up / down button of the remote control unit 5 or the numeric keypad, the skip time (skip interval) in the forward direction and the reverse direction can be arbitrarily set. Can be set.

  Hereinafter, procedures of video data skip reproduction processing and reverse skip reproduction processing by the control unit 1 of the data reproduction apparatus 20 according to the second embodiment of the present invention will be described with reference to the flowchart of FIG. In the following description, it is assumed that the skip times in the forward direction and the backward direction are set to α minutes and β minutes, respectively.

  First, the control unit 1 inputs a skip button (skip button 48 of the operation unit 4 or a skip button of the remote control unit 5) as an input of a skip playback instruction, or a reverse skip button (reverse skip of the operation unit 4) as an input of a reverse skip playback instruction. It is monitored whether the button 49 or the reverse skip button of the remote control unit 5 is pressed (S21).

  If neither the skip button nor the reverse skip button is pressed in step S21, the control unit 1 continues to monitor pressing of these buttons.

  When the skip button is pressed in step S21, the control unit 1 counts the number of times the skip button is pressed (S22), and then reads the video data from the HDD 10 for the total skip time (= skip time × The physical address is skipped by an interval corresponding to the number of times the skip button is pressed, and the video data is reproduced from this physical address (S23).

  Specifically, if the skip button is pressed once / continuously five times before the start of video data playback, for example, the total skip time is α minutes / 5α minutes, so it is not from the recording start address. Then, video data is reproduced from the physical address corresponding to α / 5 / 5α skipped at once. Along with this, the video from α / 5 / 5α is displayed on the television 40, and sound is output.

Also, if the skip button is pressed once, for example, five times in a state where the physical address that has been played once or has been paused and corresponds to (t ₁ ), skipping Since the total time is α minutes / 5α minutes, video data is reproduced from a physical address corresponding to (t ₁ + α) minutes / (t ₁ + 5α) minutes. Accordingly, video from (t ₁ + α) minutes / (t ₁ + 5α) minutes is displayed on the television 40, and sound is output.

  Subsequently, the control unit 1 determines whether or not the reproduction of the video data is completed (S24). If it is determined that the reproduction is not completed (S24: NO), the control unit 1 continues the reproduction of the video data, proceeds to step S21, and repeats the subsequent processes. On the other hand, when it determines with reproduction | regeneration having been completed (S24: YES), the control part 1 complete | finishes a process.

  When the reverse skip button is pressed in step S21, the control unit 1 determines whether or not the reverse skip button is pressed before starting the reproduction of the video data (S25).

  If it is determined in step S25 that the reverse skip button has been pressed before starting the reproduction of the video data (S25: YES), the control unit 1 ends the process.

  On the other hand, when it is determined in step S25 that the reverse skip button has not been pressed before the start of reproduction of the video data (S25: NO), the control unit 1 counts the number of times the reverse skip button has been pressed ( S26) Next, the video data is read from the HDD 10 from the physical address that is reverse skipped by an interval corresponding to the total reverse skip time (= reverse skip time × number of times the reverse skip button is pressed), and the video data is read from this physical address. Playback is performed (S27).

Specifically, when the reverse skip button is pressed, for example, once / continuously five times in a state where the physical address that has been played once or has stopped playing corresponds to (t ₂ ) minutes. Since the total reverse skip time is β minutes / 5β minutes, the video data is reproduced from the physical address corresponding to (t ₂ −β) minutes / (t ₂ −5β) minutes. Accordingly, video from (t ₂ −β) minutes / (t ₂ −5β) minutes is displayed on the television 40 and sound is output.

  After the process of step S27, the control unit 1 proceeds to step S24 and repeats the subsequent processes.

  In addition, after performing the above skip reproduction (step S23) or reverse skip reproduction (step S27), normal operation of the fast forward button 45 / fast reverse button 43 of the operation unit 4 or the fast forward button / fast reverse button of the remote control unit 5 is performed. Of course, the physical address at which reproduction is started can be finely adjusted by the pressing operation.

  In the present embodiment, the skip playback process and the reverse skip playback process are counted by pressing the skip button and the reverse skip button, and the skip playback and the reverse skip playback are performed for each set interval according to the counted number. Although it was configured, the present invention is not limited to this, and after pressing the skip button or the reverse skip button, by inputting a numerical value with the numeric keypad of the remote control unit 5, according to the input numerical value, skipping at set intervals It may be configured to perform playback and reverse skip playback.

(Embodiment 3)

This will be described below.

  FIG. 8 is a flowchart showing procedures of video data skip reproduction processing and reverse skip reproduction processing by the control unit 1 of the data reproduction apparatus 20 according to the third embodiment of the present invention. Note that the video data to be processed has a total playback time of r minutes.

  First, the control unit 1 inputs a skip button (skip button 48 of the operation unit 4 or a skip button of the remote control unit 5) as an input of a skip playback instruction, or a reverse skip button (reverse skip of the operation unit 4) as an input of a reverse skip playback instruction. It is monitored which of the buttons 49 or the reverse skip button of the remote control unit 5 is pressed (S31).

  If neither the skip button nor the reverse skip button is pressed in step S31, the control unit 1 continues to monitor pressing of these buttons.

  When the skip button is pressed in step S31, the control unit 1 counts the number of times the skip button is pressed (S32), and then reads out the video data from the HDD 10 and reproduces the physical address section to be reproduced. The processing is performed from the physical address corresponding to the time divided into two, and the video data is reproduced from this physical address (S33).

  Specifically, when the skip button is pressed twice, for example once / continuously before starting the reproduction of the video data, the time obtained by dividing the reproduction time of the physical address section to be reproduced is (r / 2). ) Minutes / (3r / 4) minutes, video data is reproduced not from the recording start address but from the physical address corresponding to (r / 2) minutes / (3r / 4) minutes skipped at once. Accordingly, video from (r / 2) minutes / (3r / 4) minutes is displayed on the television 40, and sound is output.

Also, if the skip button is pressed twice, for example once / continuously, in a state where the physical address that has been played once or has been paused and corresponds to (t ₃ ) Since the time obtained by dividing the reproduction time of the physical address section to be divided is (rt ₃ ) / 2 minutes / 3 (rt ₃ ) / 4 minutes, (rt ₃ ) / 2 minutes / 3 ( Video data is reproduced from the physical address corresponding to rt ₃ ) / 4 minutes. Accordingly, the video from (rt− ₃ ) / 2 minutes / 3 (rt− ₃ ) / 4 minutes is displayed on the television 40, and sound is output.

  Subsequently, the control unit 1 determines whether or not the reproduction of the video data is completed (S34). When it is determined that the reproduction is not completed (S34: NO), the control unit 1 continues the reproduction of the video data, proceeds to step S31, and repeats the subsequent processes. On the other hand, when it determines with reproduction | regeneration having been completed (S34: YES), the control part 1 complete | finishes a process.

  If the reverse skip button is pressed in step S31, the control unit 1 determines whether or not the reverse skip button is pressed before starting the reproduction of the video data (S35).

  If it is determined in step S35 that the reverse skip button has been pressed before starting the reproduction of the video data (S35: YES), the control unit 1 ends the process.

  On the other hand, when it is determined in step S35 that the reverse skip button has not been pressed before the start of reproduction of the video data (S35: NO), the control unit 1 counts the number of times the reverse skip button has been pressed ( S36) Next, the video data is read out from the HDD 10 from the physical address corresponding to the time obtained by dividing the reproduction time from the recording start physical address to the physical address being reproduced or the physical address at which reproduction is paused. The video data is reproduced from (S37).

Specifically, when the physical address during playback or when playback is paused corresponds to (t ₄ ), and the reverse skip button is pressed twice, for example once / continuously, the recording start physical Since the time obtained by dividing the reproduction time from the address to the physical address being reproduced or the physical address where reproduction was paused is (t ₄ ) / 2 minutes / (t ₄ ) / 4 minutes, (t ₄ ) / 2 minutes Video data is reproduced from a physical address corresponding to / (t ₄ ) / 4 minutes. Along with this, the video from (t ₄ ) / 2 minutes / (t ₄ ) / 4 minutes is displayed on the television 40, and sound is output.

  After the process of step S37, the control unit 1 proceeds to step S34 and repeats the subsequent processes.

Here, in order to perform playback from the physical address of the first half of the video data without performing a normal playback start instruction in a state where playback has not yet been performed, a skip instruction and a reverse skip instruction are sequentially performed in this order. Good. Therefore, when the skip instruction and the reverse skip instruction are received once in this order for the data of the total playback time r, the physical address corresponding to r / 4 minutes (that is, 1/4 of the whole is 0 + 1). from / 2-1 / 2 ^second physical address) can reproduce the video data.

  In addition, after performing the above skip reproduction (step S33) or reverse skip reproduction (step S37), the normal operation of the fast forward button 45 / fast reverse button 43 of the operation unit 4 or the fast forward button / fast reverse button of the remote control unit 5 is performed. Of course, the physical address at which reproduction is started can be finely adjusted by the pressing operation.
