摘要:
Communication between an image-information storage device and a terminal is made possible even in a case where they have images of different image formats. An image data delivery request, transmitted from any of a plurality of terminals and received by a receiving portion, includes information indicating that the terminal has a source format of CIF or QCIF. This information is transferred to a communication control portion which informs the source format control portion of the source format (CIF or QCIF of) the terminal. When the terminal has the CIF source format, the required data transmitted from an image-information storage device are transmitted through a transmitter portion to the terminal. When the terminal has the QCIF source format, a part of the image data transferred from the image-information storage device is extracted and converted into data of QCIF format by the source format control portion. The converted data of QCIF source format are then transmitted through a transmitting portion to the terminal.

A device which is capable of storing moving picture data received from each terminal and providing each terminal with video information to be reproducible by rapidly forwarding or reversing at any desired speed independent of usable terminals. A video storage type communication device 30 with a receiving portion 35 and a transmitting portion 38 transmits and receives video data over a communication network 10 to and from each terminal 1–n. A coded video data received from terminals 1–n is stored as it is in a first storage portion 32 and, at the same time, the data converted into specially reproducible video information is stored in the second storage portion 33. At the time of reproducing, the reproduction control portion 35 controls the reproduction selector switch 36 to obtain the video data from the first storage portion 32 or the second storage portion 33, changing the reproduction mode from ordinary to the rapid forwarding/reversing and vice versa. The specially reproducible video generating portion 34 successively restores coded video data received through the receiving portion 31, encodes again the restored data by intraframe, interframe or still-picture coding method to generate video information to be reproducible in special mode such as reproduction by rapid forwarding or reversing.

The present invention provides such a data storing format that is effective for solving problems which may arise when regenerating video data in a video data storage and communication system. A channel data demultiplexing portion splits a multiplexed input into audio/video and other components. An error correction portion corrects an error of the video data output from the channel data demultiplexing portion. A video frame extracting portion extracts a video frame output from the error correction portion. A packet assembling portion assembles a packet from the video data output from the video frame extracting portion and the audio data output from the data demultiplexing portion. A storage portion stores therein the packet output from the packet assembling portion. Consequently, video data can be stored by video frames.

摘要:
A connection control equipment can connect a plurality of calls originating from a terminal to a private side terminal by identifying the calling terminal. Each of the user terminals sets a calling number and a calling sub-address or a user-to-user information for identifying the terminal in a call-setting message. A switching system of the connection control equipment receives the call-setting message and stores the calling number and the calling sub-address or the user-to-user information of the message, and connects the call to a private side terminal with which the same user terminal issuing the just received call is communicating. The switching system can connect calls from the same user terminal to the same private terminal, allowing for any user terminal to freely transmit a plurality of calls without considering how to access a host computer.

The bonding sheet of the present invention comprises a substrate having an opening, and a low-melting point bonding metal which closes the opening or is arranged on the peripheral portion of the opening, to project in the opening. According to a bonding sheet of the present invention, a low-melting point bonding metal is interposed between a conductor pattern of a substrate and electrode terminals of an electronic component, and is bonded by thermocompression at a low temperature without melting the low-melting point bonding metal, so that bonding of a large number of electrode terminals can be completed by a single bonding operation.

摘要:
A tracer memory (7) stores the history of execution of addresses for the microprogram of an information processing unit to provide clues to the identification of the cause of any exceptional event that may occur in the unit. A pointer register (10) is indexed by one to store in the tracer memory the state of a predetermined group of logical signals at a location designated by the pointer value. When the result of addition to the pointer value surpasses the end address of the tracer memory, the pointer value is changed to the head address of the tracer memory so that data previously written is over written. The tracer memory contains N addresses and on the occurrence of an exceptional event, the current address J in a pointer register is stored in a mask end register 12 and a preceding address I, separated by a predetermined number M of addresses from address J, is stored in a mask start register 11. The value J-M is stored in said mask start register if J-M>0; otherwise, the value {N+(J-M)} is stored. If a second exceptional event occurs during the execution of a failure recovery procedure for the first exceptional event, there is preserved the execution history of the failure recovery procedure caused by the first exceptional event.

A data processing apparatus includes segment and page descriptors as a control structure for realizing a logical address, a step counter, and a count control means. The step counter is incremented or decremented every time a machine instruction is executed. The count control means causes the step counter to count or stop counting in accordance with data in the segment or page descriptor of a segment or page in which a machine instruction to be executed is present.
