摘要： A widescreen television signal containing center panel information and time compressed side panel information in an overscan region is intraframe processed above a given frequency only with respect to the center panel information. The intraframe processing apparatus includes a signal delay network with first and second 262H delay elements coupled between an input and an output of the delay network. During a first field interval, signals from the delay input and from an intermediate point between the delay elements are subtractively combined to produce a difference term which is coupled to a signal path. During a second field interval, signals from the delay output and from the intermediate point are subtractively combined to produce a difference term which is coupled to the signal path. An intraframe processed output signal is produced by combining the difference terms from the signal path with a signal from the intermediate delay point. A filter and an electronic gate in the signal path determine frequency selective intraframe processing of the center panel information alone.

摘要： A film/video detector includes circuitry for generating the differences between corresponding pixel values in successive frames of video signal. These differences are accumulated over respective frame intervals. Accumulated values for respective frames are applied to a signal averager and to a correlation circuit. Average values from the averager are subtracted from correlation values from the correlation circuit, and film mode signal is indicated if the latter differences are greater than a predetermined value.

摘要： An NTSC compatible, single channel widescreen EDTV system encodes and decodes a television signal comprising (1) a main, standard format NTSC signal with auxiliary low frequency side panel image information compressed into an overscan region thereof; (2) auxiliary high frequency side panel image information; and (3) auxiliary high frequency horizontal luminance information. At an encoder, components 2 and 3 are intraframe averaged before modulating an alternate subcarrier. Component 1 is intraframe averaged above a given frequency before being combined with the modulated alternate subcarrier.

摘要： In a television signal processing system of the type which encodes an auxiliary carrier modulated with auxiliary image information in line format, which carrier is placed within the spectral band of standard television signal components, and wherein the modulated auxiliary carrier tends to interfere with the standard television signal, the interference is minimized by spatially variably attenuating the auxiliary image information. The attenuation function is selected to apply greater attenuation to the auxiliary image information at the extremities of the lines than toward the center of the lines.

摘要： A method for decoding variable length encoded digital video data including pictures, to a size less than the full size of the pictures, each picture including a plurality of macroblocks. The method comprises the steps of receiving digital video data; parsing the digital video data to identify macroblocks included in the digital video data; discarding from the digital video data those macroblocks not associated with a picture region substantially corresponding to one of a safe-title picture region and safe-action picture region; and storing the digital video data in a decoder input buffer.

摘要： By employing different independent polarity codes to polarity-modulate respective quads of averaged values in the vertical-temporal plane of luma, chroma, sidepanel and enhanced-luma components in the mid-frequency and/or high-frequency split-bands of a 4.2 MHz baseband television-type signal, the encoded components can be combined into successive composite quads of an encoded single channel, NTSC compatible, enhanced-definition 4.2 Mhz bandwidth television signal. The successive composite quads of the encoded signal can be decoded by a widescreen receiver without crosstalk taking place among the components, while such an encoded signal does not noticeably affect the display of a standard NTSC receiver.

摘要： An apparatus for correcting errors in color signal transitions includes a signal scaling device and a signal mixing device. A wide bandwidth luminance signal is applied to the signal scaling device which develops a limiting signal for a particular narrow bandwidth color difference or primary color signal. This limiting signal is mixed with its associated color difference or primary color signal by the signal mixing device. The output of the signal mixing device is a color difference or primary color signal that has amplitude values less than or equal to the amplitude values of the limit signal.

摘要： Main panel and side panel components of a widescreen television signal are intraframe processed over different frequency ranges, resulting in a noticeable difference between "judder" motion artifacts of main and side panel images displayed by a receiver. A side panel field difference signal encoded in a transmitted widescreen signal is used by a receiver to eliminate the differential judder effect of displayed main and center panel information. The field difference signal contains field difference information over a range of frequencies between a first frequency above which the main panel component is intraframe processed, and a different second frequency above which the side panel component is intraframe processed.

摘要： In a system for encoding and decoding high frequency video information, an input video signal includes a high frequency band containing information to be encoded, and a lower frequency band. The frequency spectrum of the input video signal is folded around a frequency in the lower frequency band. A resulting folded video signal is combined with the input video signal to produce a combined signal which is low pass filtered by a filter having a cut-off frequency corresponding to the folding frequency. The filtered combined signal is separated into its constituent filtered video signal and filtered folded video signal parts. The separated folded video signal component is unfolded around the folding frequency to produce an unfolded video signal with frequencies in the high frequency band. The unfolded video signal is joined to the high frequency band of the separated video signal to produce an output video signal having a high frequency band with the uppermost frequencies thereof determined primarily by the unfolded video signal.
