    摘要: Wide-band multi-format audio/video production system with frame-rate conversion and methods performed by the audio/video production system. Compressed video content corresponding to an original format of a video program is processed to generate uncompressed video content in an internal format having a frame rate of 24 frames per second (fps) comprising progressive frames of pixel image data having an original pixel resolution. Progressive frames of pixel image data are buffered in a high-capacity memory buffer supporting asynchronous random read and write access. The progressive frames of pixel image data in the buffered progressive frames are processed to perform a frame-rate conversion from 24 fps to a higher output frame rate to produce progressive frames of converted video content having an uncompressed format. The progressive frames of converted video content are the stored in a compressed video format to produce a converted video program having a converted frame rate in accordance with the higher output frame rate.

    摘要: A multi-format digital video production system enables a user to process an input video program to produce an output version of the program in a final format which may have a different frame rate, pixel dimensions, or both. An internal production format of 24 fps is preferably chosen to provide the greatest compatibility with existing and planned formats associated with HDTV standard 4:3 or widescreen 16:9 high-definition television, and film. Images are re-sized horizontally and vertically by pixel interpolation, thereby producing larger or smaller image dimensions so as to fill the particular needs of individual applications. Frame rates are adapted by inter-frame interpolation or by traditional schemes, including “3:2 pull-down” for 24-to-30 fps conversions. Simple speed-up (for 24-to-25 conversions) or slow-down (for 25-to-24 conversions) for playback, or by manipulating the frame rate itself using a program storage facility with asynchronous reading and writing capabilities. The step of converting the signal to a HDTV format is preferably performed using a modified upconversion process for wideband signals (utilizing a higher sampling clock frequency) and a resizing to HDTV format frame dimensions in pixels.

    摘要: An image signal recording device records image signals in a HDTV mode onto a magnetic disk in accordance with a predetermined mode, for example, an NTSC mode. The NTSC mode is provided with a vertical blanking period and horizontal scanning periods in which image signals are recorded. A part of the image signals are recorded in a part of the vertical blanking period, so that the number of scanning lines per one field is increased in comparison with a conventional device; thus, as much as possible of the HDTV mode image signals are recorded on the magnetic disk.

    摘要: A switching circuit to selectively generate either one of an image pickup signal from an image pickup device and a reproduction video signal in which when the recording mode is set, the switching circuit is set to the side on which the image pickup signal from the image pickup device is supplied. When the reproducing mode is set, the switching circuit is set to the side on which the reproduction video signal is supplied. When the instantaneous reproduction is executed in the recording mode, the optical information from an optical information detecting circuit just before the switching circuit is switched from the side on which the image pickup signal is supplied to the side on which the reproduction video signal is supplied is held. An output of the switching circuit is converted into a digital signal. The digital signal is supplied to a digital signal processing circuit to process the digital signal and is also supplied to the optical information detecting circuit to detect the optical information.

    摘要: A video signal recording method and apparatus in which a video signal for a high definition television system is converted into a video signal for a current television system and recorded on record media. These video signals are recorded so as not to cause a deterioration in picture image quality such as color phase irregularity. According to the present video signal recording method, a screen to be displayed in a high definition television system is divided into a plurality of screens, video signals of each of which are then converted into signals of a current television system. A luminance signal and a chrominance signal of each of the signals of the current television system are time division multiplexed. Signals obtained from the time division multiplexing are recorded onto a plurality of record media with or without a color burst signal added thereto for each line.

    摘要: Extended definition television (EDTV) signals including a compatible composite wideband signal and a separate helper or extended definition signal are combined, for example, for recording purposes, using frequency multiplexing techniques. The helper signal is applied to a modulator, which produces a suppressed carrier modulated signal, to frequency shift the helper signal to a spectral band above the frequency band occupied by the compatible composite wideband signal. The frequency shifted and wideband signal are then added to form the combined signal.

    摘要: Apparatus and method for encoding and recording electronic image information signals in a manner whereby luminance signals for odd field lines are recorded in association respectively with chrominance signals alternately selected from both the even field lines and the odd field lines and luminance signals for even field lines are recorded in association respectively with the remaining chrominance signals alternately selected from both the even field lines and the odd field lines. Chrominance samples recorded in this manner are spaced only two field lines apart thereby allowing the chrominance signals to be interpolated by a playback device specially configured to provide for increased vertical chromianance resolution. Chrominance samples recorded in this manner may also be played back with a conventional playback device, which does not provide the increased vertical chrominance resolution while such a specially configured playback device can play back chrominance samples recorded in standard format without providing the increased vertical chrominance resolution.
