Abstract: A hardware configuration suited for a digital video and audio signal broadcast system such as a near-video on-demand apparatus (NVOD apparatus) includes a compilation unit, a play-out unit, a transmission unit, and a subscriber unit. The compilation unit stores several weeks to several months worth of the video and audio signals obtained by reproducing, compressing, encoding, and editing the broadcast stock according to a long term broadcast schedule of several weeks to several months. The play-out unit stores the video and audio signals stored in the compilation unit for several days to several weeks according to a broadcast schedule of several days to several weeks, reproduces the video and audio signals which become necessary for the real time broadcast, and adds a time difference to these video and audio signals distributed to a plurality of channels.

Abstract: A data transmission apparatus comprising: data supplying unit for storing a plurality of types of data and simultaneously transmitting the plurality of types of data to a plurality of selected channels respectively; switching unit for outputting the plurality of types of data outputted from the data supplying unit to the selected different channels respectively; data storage unit for storing the data outputted from the selected channels after rearranging the data in a predetermined order; and data outputting unit for simultaneously outputting the data stored in the data storage unit from the plurality of channels after shifting the data by a certain amount.

Abstract: A disc control apparatus handles an even number of disc-shaped recording mediums run in rotation at a constant angular velocity and to which addresses are accorded for incrementing from an inner disc rim side or from an outer disc rim side. The disc control apparatus effectuates data accessing with the disc-shaped recording mediums in terms of a pre-set block as a unit. The control apparatus includes an accessing control unit which effectuates data accessing on the block basis by addressing from the outer disc rim side for one of the disc-shaped recording mediums of the set while effecting data accessing on the block basis by addressing from the inner disc rim side for the other disc-shaped recording medium of the set. During data recording/reproduction, one of two contiguous blocks is recorded/reproduced on the disc-shaped recording medium accessed from the outer disc rim side while the other block is recorded/reproduced on the disc-shaped recording medium accessed from the inner disc rim side.

Abstract: A data transmission apparatus suitable for use for a VOD system etc. able to supply program data in response to a request made at any time. In the data transmission apparatus (1) of the present invention, the video data to be supplied is first transferred to a high speed accessible recording apparatus in the transmitter (10.sub.-i). This recording apparatus for example performs high speed access in less than a fraction of the real time of the video data and reproduces several locations predetermined time intervals apart simultaneously. At this time, preferably an error correction code is pre-recorded at the time of recording in the recording apparatus. At the time of reproduction, the apparatus reads data from the recording apparatus at a high speed in units of physical blocks of the transfer data of the recording apparatus, adds header information etc. by the formatter (20.sub.-i) to make the formats match, produces ATM cells, and outputs them through the data exchange (60) to the transmission lines.

Abstract: The image data transmission apparatus for transmitting image data signal to a plurality of end devices corresponding to the request from each end device, divides the input image data signal into a plurality of unit image data to subsequently store it on the recording medium, controls operation of the plural storing means so that the unit image data for each end device is read out by time division from the recording region in each storing means which is different from each other corresponding to requests from each end device, combines the unit image data for each end device which is read out from each storing means by each end device to form image data signal for each end device, and transmits it to each correspond end device.

Abstract: A data transmission apparatus suitable for use in a VOD system which can send program data in response to requests made at any time. In the data transmission apparatus of the present invention, a series of data is read from a mass storage at a high speed referring to a data recording table in which are recorded the head address and magnitude of the series of data which are to be simultaneously read and the magnitudes of the individual data. For the read data, the magnitudes of individual data of the table are referred to, separated to individual data, and recorded in the buffer memory (33.sub.-1 to 33.sub.-n) for every output channel. The data is appropriately processed and transmitted for every channel by the buffer memory controllers (32.sub.-1 to 32.sub.-n) provided for every output channel and output controllers (35.sub.-1 to 35.sub.-n) and formatter.

Abstract: In a video system red, green, and blue color signals, which correspond to an output video signal, are offset-sampled and thereafter supplied to a switching circuit. The offset-sampled color signals reproduced from VTRs are supplied to the switching circuit. The offset-sampled color signals selected by the switching circuit are supplied to a special effect applying apparatus, and the processed color signals are supplied to the switching circuit. The offset-sampled color signals selected by the switching circuit are decoded by way of interpolation processing to obtain the output video signals.

Abstract: An image out put system including an image printer 53 for printing images on a lenticular lens sheet 16 and a computer for controlling the image printer 53, while a plurality of images are being superimposition printed on the lenticular lens sheet 16, by making the size and the feed for each pixel smaller in the first direction so as to superimpose pixels when printing, or by narrowing the shape of each pixel in this first direction and then reducing the feed for each pixel by the portion by which each of the pixels have been narrowed. It is possible to make the number of pixels per unit length of the first direction large.
