    摘要: A television signal format converter is provided for converting without loss of picture information any high definition television format to or from a given recorder/player format. An interface converts between RGB and luminance/chrominance inputs and between analog and digital inputs. The interface couples any proposed high definition television format to a plurality of pairs of memories. A clock and control circuit controls addressing of the memories for reading and writing so that conversion is performed between any high definition television format and the format required for a given high definition digital video tape recorder or any other comparable recorder. As data is stored in the digital video tape recorder, dummy samples are written along with active luminance samples. The dummy samples may indicate, among other things, the type of format being converted.

    摘要: A system for converting an input television signal that contains field sequences corresponding to frames in cine film is provided. The input signal is converted into an intermediate television signal wherein there is a direct correlation between the field groups thereof and the original film frames. The intermediate signal is modified to produce and output television signal whose field rate is that of a desired television signal. For example, the input signal can be an NTSC signal produced in part from a 3:2 pull down technique, the intermediate signal may be characterized by 625 lines and 48 fields per second or characterized by 525 lines and 625 fields per second, and the output signal can be a PAL signal characterized by 625 lines and 50 fields per second. In each case, a 3:2 sequence of input signal fields (correlated with cine frames) results in pairs of fields in the output signal correlated with the cine frames. A television signal standards converter and a frame detector for use in the system are provided.

    摘要: An image signal converter in the receiver of a facsimile system comprising a first memory for memorizing successive horizontal line signals contained in an image signal carried on a facsimile signal transmitted, and a second memory for consecutively memorizing the horizontal line signals by one field. The first memory is adapted to memorize the horizontal line signals reversely of the time base when the horizontal scanning direction in the sender is reversed and, on the other hand, the second memory is adapted to memorize the horizontal line signals in reverse order when the vertical scanning direction in the sender is reversed.

    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.
