Abstract: A signal editing and processing technique for converting a plurality of continuous signals, especially long term continuous audio signals respectively relating to short term still picture signals, to a transmitting signal in which signal transmission periods and pause periods are provided, having an integer ratio of time duration with each other, wherein other signals, especially the picture signals, should be transmitted. All continuous signals are sequentially converted to digital signals addressed in accordance with relevant continuous signals, and once stored in arbitrary positions of a memory, and then read out in a given multiplexed sequence corresponding to the transmission periods of the transmitting signal. The read out multiplexed digital signals are sequentially stored in another memory, and then read out with a given high speed equal to that of the signal transmission. The digital signals read out with the high speed are stored in still another memory, and then read out repeatedly to form the transmitting signal.

Abstract: There is provided a receiving system for receiving the video signal for each one frame. The video signal is divided into line signals each corresponding to the horizontal scanning period and transmitted sequentially in such a manner that each line signal is inserted in a television signal during each vertical blanking period.The line signals inserted in the transmitted television signal are separated therefrom and the separated line signals are selectively recorded on the odd and even field tracks of a rotary recording medium.Switches for selectively recording the line signals on the even field and odd field tracks are controlled by the output of an odd/even field selection signal generating circuit. The number of revolutions of the rotating recording medium is determined so that the line signals selectively recorded on the even field and odd field tracks of the rotating recording medium are arranged in the correct order and without leaving any spaces between the line signals or causing the line signals to overlap with each other. When the video signals for one frame have been recorded on the rotating recording medium, the one-frame video signals recorded on the rotating recording medium are repeatedly read out to reproduce a still picture.

Abstract: A multiplex signal transmission system in which a plurality of information signals, having respectively arbitrary time durations and being arranged in time-serial form, are sequentially divided into a plurality of signal portions by a predetermined time period, said signal portions being successively allocated in time-parallel form to a plurality of transmission channels, each of which has a time duration of said predetermined time period, and being transmitted repeatedly through respectively allocated channels every said time duration, comprises a channel shift means for shifting sequentially the channel allocation of said signal portions at predetermined time periods, and a signal transmitting means for transmitting in time-parallel form said signal portions derived from said channel shift means repeatedly through every preceding channels. Consequently, the transmission line can be efficiently utilized in such a way that, at the sending end, a plurality of information signals having respectively arbitrary time durations are folded into a plurality of transmission channels having given time periods, and besides that, at the receiving end, once a portion of any desired information signal is caught in a corresponding channel, successive signal portions can be derived sequentially from the same channel every said given time periods. Hence, a channel selecting means of a receiver in this system can be simplified.

Abstract: In an ATM connectionless communication system for delivering connectionless datagram in the form of sessions through an ATM network, each one of multiple edge units is connected to a user network where quality-of-service (QoS) sessions and No-QoS sessions are mixed. Each of the edge units accommodates an IPv4 packet from the user network into an intermediate frame and accommodates the intermediate frame into ATM cells. The edge units are connected to core units by permanent virtual paths to form a connectionless network. Each of the edge units has a session supervising section for determining whether the IPv4 packet is a QoS session or a No-QoS session, to allocate a control flow number to the IPv4 packet when the IP4 packet is a QoS session.

Abstract: A memory controlling apparatus for a magnetic recording and reproducing apparatus which records and reproduces a field image signal in each read or write cycle performed by a video head for reproducing the image signal from a magnetic tape, and by a video head position detector for detecting the position of the video head. A reference circuit obtains a signal defining a reference timing which is independent of the position of the video head and which is also used to determine the phase of the video head. A memory is provided having storage sufficient to store the field image signal, and a controller is provided for controlling the operation of reading and writing the image signal from and into the memory. The controller is synchronized with a signal of the video head position detector when storing the image signal into the memory and when reading out the image stored in the memory, the controller and the head position detector are synchronized with the reference timing so as to enable production of a slow-motion image signal free from fluctuations caused by feeding of the magnetic tape.

Abstract: A picture-in-picture television receiver is disclosed in which a television picture to be inset is compressed at a compression rate of 1/n and inset as a small-picture in part of a main television picture or large picture, and a single field memory for small-picture reproduction is provided therein in or from which a video signal can be randomly read and written line by line as a unit. In the single field memory is stored the small-picture video signal line by line by the application of a writing clock in which case the time taken in the writing is less than 1/(n+1) of a horizontal period. Then, from the memory is read the stored small-picture information by the application of a reading clock of n times the frequency of the writing clock during the time that writing is not performed, and supplied to be inset in the main television picture. A small-capacity buffer memory is provided at the prestage or following stage of the field memory to prevent the read/write timing overlap in the field memory irrespective of whether the small-picture and the main television picture are synchronized or not in the transmission systems. Thus, the capacity of the field memory essential for the small-picture is about a half of the conventional one.
