1. More specifically in Step S501 the CPU 271 switches to the clip A upon receiving the signal from the controller 111 in response to the user s input for example pressing the selec tion button 220A of the controller 111 corresponding to the clip A In a case of reading the moving image data of the clip A while the camcorder 121 is taking images the CPU 271 reads the latest replayable moving image data in the clip A for example moving image data located slightly before for example a few frames to some dozens of frames before the time point where the switching operation to the clip A was executed Thus the latest moving image data requested by the user can be quickly read Alternatively in a case where the camcorder 121 is not taking images the moving image data at a predetermined point for example at the beginning or at the end of the clip A can be read This allows the user to locate intended moving image data without erroneous operation since the reading of the moving image data always starts from the predetermined point In this case the clip A is still in recording thus the CPU 271 reads the latest replayable moving image data of the clip A from the hard disk drive 261 decodes the read data by the decoder 241 and displays the decoded data on the decoder monitor 134 Further the CPU 271 reads the moving image data sequentially backwards from the latest point to the point H where the batter has hit a home run in this case in2. especially in a live sport telecast and the like to concatenate a plurality of scenes recorded by a plurality of camcorders or to change the duration of each of the scenes the plurality of scenes are played back and edited using a recording playback device including a recording medium allowing for a faster random access such as a hard disk device While such a recording playback device including a recording medium allowing fora faster random access is improved in convenience in compari son with a video tape recorder carrying out a sequential access still much is left to be improved in terms of operabil ity For improved operability Japanese Unexamined Patent Application Publication No H09 233430 discloses a device for recognizing an order and duration of a series of scenes to be played back and further editing the series of scenes by for example displaying in chronological order the series of scenes to be played back in a bar chart having segments reflecting the duration of each of the scenes Patent Citation 1 Japanese Unexamined Patent Application Publication No H09 233430 DISCLOSURE OF INVENTION Technical Problem In a live sport telecast for example in a live baseball game broadcast a controversial play or a home run scene is often broadcasted immediately after it occurs In this case it is preferable that a plurality of moving images taken from a plurality of angles are edited and broadcasted before viewers lose interes

12. 1 sends a signal in response to the pressing operation The CPU 271 in response to the signal switches to the clip A and reads the in point in A stored in the memory 281 and prepares to read the moving image data at the in point from the hard disk drive 261 US 8 891 941 B2 11 As described above the in points in A to in C are respec tively set on the clips A to C Each of the in points in A to in C is set at a time point on a clip where moving image data is last played back before switching in response to the switching request between clips without any input operation by the user This does not require the user to set the in points thus allowing quick editing In the following description regarding Step S601 to Step 625 of FIG 6 and regarding FIG 8 the steps are described for playing back the clips A to C with the in points being set as a playback Time lines 801 to 803 of FIG 8 respectively show the time information of the clips A to C as points on a straight line As shown in FIGS 6 and 8 in Step S601 the CPU 271 starts playing back the clip A from the in point in A More specifically if it is determined that the switching request has been made in the abovementioned Step 535 of FIG 5 the CPU 271 prepares to read the clip A from the in point in A from the hard disk drive 261 The CPU 271 reads the clip A sequentially from the in point in A in response to a playback start request from the user and outputs the m
13. 20 The output 251 receives the moving image signal that has been decoded from the decoder 241 and outputs the signal to the decoder monitor 134 and the transmitter 140 The output 251 outputs the moving image signal in a format compliant witha device that is connected to the output 251 For example a VGA signal is outputted from the output 251 to the decoder monitor 134 and an HD SDI signal is outputted from the output 251 to the transmitter 140 Further the output 251 may receive and output the moving image signal that has been read from the input 201 and the hard disk drive 261 or the encoded moving image data from the input 201 and the hard disk drive 261 or may receive the encoded moving image data from the encoders 211 213 and output the received encoded moving image data The hard disk drive 261 stores programs that are to be executed by the CPU 271 and the encoded moving image data sent from the encoders 211 213 Furthermore the hard disk drive 261 may directly store the moving signal sent from the input 201 The hard disk drive 261 may be provided within the image server 101 externally to the image server 101 or both Still further while the present embodiment of the present invention describes the hard disk drive 261 for explanatory purposes any memory device for example such as a tape drive an optical disk drive a large volume memory or any combination thereof may be used other than a hard disk drive as long as such a de
