摘要： A method and apparatus for introducing a pan and scan feature to a multiple-signal high definition television (HDTV) system, so that a compatible signal received by a standard TV receiver may be a panned version of a wide aspect ratio HDTV signal, and so that high quality recombination of the compatible and augmenting signals by an HDTV receiver is possible. A pan and scan data word representing the relative movement of the compatible portion of the HDTV signal is inserted during the vertical blanking period of each frame of the HDTV signal, for causing panning synchronization between an HDTV transmitter and an HDTV receiver. The pan and scan data word corresponds to the beginning read address of a fixed coefficient memory containing video attenuation coefficients, which determine the degree of signal attenuation, to be applied at each pixel location along an HDTV scan line. The coefficient memory is addressed in a wrap-around manner, so that if the starting address in the read cycle is other than zero, the reading continues until the highest address in the memory is reached, and then address zero et seq. are read on up to the address before the starting address. By changing the points of passage, attenuation and suppression along scan lines, panning occurs.

摘要： A method and apparatus for encoding a television source signal having a first bandwidth, into a frequency multiplexed signal having a narrower bandwidth and comprising a plurality of subcarriers modulated with digital information. Each of said subcarriers has an amplitude, bandwidth and coding characteristic which reflects the relative importance of the digital information provided thereby. The frequency multiplexed signal is suitable for use in a broadcasting environment wherein a conventional television signal is also used and wherein said subcarriers are disposed in frequency, in positions which are least likely to result in interference to or from said conventional signal. The invention also includes a receiver for decoding the frequency multiplexed signal and for providing a high definition display.

摘要： Each line of a wide aspect ratio television signal is divided into a main panel component and an autmentation panel component joined to the main panel component at a stitch point for transmission or storage. At the transmitter, a first signal is extracted from the horizontal line signal, the first signal including the main panel component, a plurality of main panel redundant pixels extending from the main panel into the augmentation panel component, and a multiplicity of weighted main panel transition samples extending further into said augmentation panel component from the redundant samples. Similiarly, a second signal includes the augmentation panel component, a plurality of augmentation panel redundant samples extending into the main panel and a plurality of transition augmentation samples extending from the redundant augmentation samples further into the main panel and weighted to create a predetermined transition curve. At the receiving end, both signals are gated to delete the transition curves, and the redundant samples are linearly weighted to effect the transition from the main panel component to the augmentation panel component. When two augmentation panels are transmitted in a multiplex analog format on the same channel, they are transmitted adjacent to one another and the weighted transition augmentation samples effect a transition from the last redundant pixel of one augmentation panel component to the first redundant pixel of the second augmentation panel component.

摘要： A high definition television signal with a sequential scan with the standard number of lines per frame and double the frame frequency is processed to generate a single MAC line having a duration substantially equal to that of four sequential lines of standard duration. Each MAC line has two luminance components having different compression ratios. For the remaining two lines, compressed line difference signals are transmitted, thereby allowing reconstruction of all luminance lines at the receiver. Each MAC line further has a U chrominance component and a V chrominance component, alternatively compressed 1:4 and 1:2. The remaining parts of each MAC line are taken up by data signals and audio as well as the necessary clamping. The luminance and chrominance signals are prefiltered to prevent artifacts. The filtering is geared to the visual characteristics of the human visual system, i.e. diagonal spatial frequencies are subjected to more filtering then either purely horizontal or purely vertical spatial frequencies. The components are sampled temporilly and spatially in a diagonal direction.

The time expanded line differential signals are arranged in time coincidence and quadrature modulated, as are the corresponding segments of the panel signals. The quadrature modulations providing signals in a common frequency band. Luminance signals are converted to the common frequency band and time multiplexing of the three signals is performed. The resulting time multiplexed signal is then frequency multiplexed with the DSS signals which have been frequency converted to occupy a frequency band contiguous with the common frequency band.

摘要： Each line of a wide aspect ratio television signal is divided into a main panel component and two augmentation panel components for transmission or storage. The two augmentation panels are transmitted in a multiplex analog format on the same channel. They are transmitted adjacent to one another so that additional signals such as audio signals will occupy the same time slots regardless of the respective widths of the panels. (The sum of the panel widths remains constant even in pan and scan operations). Weighted transition augmentation samples effect a transition from the last redundant pixel of one augmentation panel component to the first redundant pixel of the second augmentation panel component.
