摘要： PROBLEM TO BE SOLVED: To improve a data transfer speed as a whole when transferring the data of a recording means to a host in response to a readout command from the host. SOLUTION: When the readout command is sent from the host not shown in the figure, the data of a data quantity (split transfer quantity) smaller than the data quantity specified by the readout command are transferred to a buffer memory 2 from the recording means 1 under the control of a system control part 6, then the data are transferred to a transfer buffer memory 5 and sent to a USB cable 8. When the data transfer from the buffer memory 2 to the transfer buffer memory 5 is finished, the next data of the split transfer quantity are transferred from the recording means 1 to the buffer memory 2, and the next data are transferred from the buffer memory 2 to the transfer buffer memory 5 and sent to the USB cable 8 from the transfer buffer memory 5 after sending the previous data to the USB cable 8 is finished.

摘要： PROBLEM TO BE SOLVED: To immediately display a small screen by request by previously generating a small screen about a still image that is needed for processing time at the time of decoding, expanding and generating a small screen, when it is encoded and compressed. SOLUTION: An encoding and decoding processing means 3 selects a still image path of a changeover switch, for instance, when an input signal is a still image. In such cases, a small screen generating means 8 is connected in parallel to a still image compressing part of the means 3, compresses a still image and simultaneously generates a small screen of the still image. The compressed still image data and a small screen data are synthesized, outputted to record control buffer memory 4 and recorded as a compressed image having small screen data. At the time of reproduction, the synthesized compressed image having small screen data are separately divided into a single compressed image and a small screen. When small screen display is requested based on the changeover of an operation switch 13, small screen data are selected, and when normal still image display is requested, image data after decoding expansion processing is performed are selected.

摘要： PROBLEM TO BE SOLVED: To configure an external equipment interface group for achieving both convenience on connection and a power saving property in an information recording/reproduction device.
SOLUTION: This information recording/reproduction device is connected through a USB-I/F9 to which power is normally supplied in order to perform access from a PC 30 having the control program of a recording/reproduction procedure to an HDD 14 or a flash memory 12 in a video camera 29. On the other hand, this information recording/reproduction device is connected through an SATA-I/F 15 to an external ODD 31 for dabbing having the control program of a recording/reproduction procedure only when it is instructed by a user by an SW 20 or only when power is supplied from an AC adaptor 17 by the control of a CPU in the video camera 29. Thus, its connection to the PC 30 is achieved in optional timing, and the power saving of the I/F to the external ODD 31 is achieved.

摘要： PROBLEM TO BE SOLVED: To improve the convenience of a user by generating a reduced picture in a specific area in a file or a reduced picture file at the time of displaying the first reduced picture thereby shortening display times on and after the second time. SOLUTION: The reduced picture is generated in the specific area in the file or the reduced picture file at the time of displaying the first reduced picture. In this device, a reduced picture retrieving part 23 retrieves specific area of a recorded file or the reduced picture file from a recording medium 9. In the case of a reduced picture existing, a reduced picture is reproduced by a reduced picture display part 14 and outputted to a graphic display 14. In the case when there is not a reduced picture, an mpeg expanding part 10 expands the leading picture of the file, a reduced picture generating part 25 generates a reduced picture, and a reduced picture recording part 26 records the reduced picture in the specific area of the file and the reduced picture file and outputs them to a recording medium 9. At the same time, a reduced picture display part 24 displays the reduced picture and outputs it to the display 14.

摘要： PROBLEM TO BE SOLVED: To display reproduction time of a recorded system steam file and to improve usability by a user by graphically displaying the data information on the system stream file and selecting this file by a button. SOLUTION: A multiplexing part 18 generates a system stream from the video and audio streams, and the system stream is recorded on a recording medium 21 as a file. A microcomputer 17 of an MPEG camera 20 reads the file information on the system stream out of the medium 21 and retrieves the recorded bit rate information. The bit rate information is integrated with the value that is decided by an MPEG1 standard, and a sound bit rate is added to the integrated bit rate information. Thus, the bit rate of the system stream is decided. The file size is read out of an FAT and the file reproduction time is calculated from the file size and the bit rate information on the system stream.

摘要： PROBLEM TO BE SOLVED: To control the operation of the data processor and to relax restriction in data transfer with a simple configuration by processing and storing or sending data generated by a data generating means externally, extracting data from received communication data, processing and storing the data and sending the data as communication data externally. SOLUTION: In the case that a video image picked up in real time is sent to a processing unit such as a personal computer with an interface circuit IF 6, compressed image data generated by a CODEC 3 are modified into a communication packet by a microcomputer 5 connected by an internal bus 8 and sent to the circuit IF 6. In the case of sending the video image from a personal computer conversely, the personal computer side generates a communication packet from the image data, converts it into an input and output signal 7 and fed to the circuit IF 6. The microcomputer 5 of the camera analyzes a received packet via the circuit IF 6, extracts image data, which are fed to the CODEC 3. The codec 3 decodes the image data, a DSP 2 converts the data into a video signal, which is fed to an LCD 10 and on which the video image is displayed.
