摘要： A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal (20, 24, 26, 32), digitizing them (26) and sending them as data in non-active video portions of the transmitted signal (30, 22). A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal (20, 24, 26, 32) and the second step removing the remainder of the video components under 200 KHz (20', 26', 32', 37, 39), is described. Temporal filtering, signal pre-emphasis, compression, dispersal and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. In an FM implementation, the benefits of the hybrid signal are realized as a reduction in bandwith and consequent improved noise performance. The hybrid signal system is uniquely adapted to a high definition television signal in a limited frequency channel.

摘要： In a widescreen television signal processing system, a side panel high frequency luminance information component (YSH) and a side panel color difference information component (QS) are combined (44) and processed as a combined signal by a noise reduction (46) encoder, time expander (60) and filter (61) before modulating (62) an auxiliary subcarrier. After demodulation at the decoder, the combined signal is filtered, time compressed and processed by a noise reduction unit before being separated into its constituent components.

摘要： Video data that is associated with a videoconference or a telepresence session is captured and a video signal relating thereto is provided. The video signal is divided into segments, which are identical from one video frame to another subsequent video frame within the video signal. Each segment is encoded independently, to result in encoded segment data such that both I-frames and P-frames are generated for a given segment, so as to support independent reconstruction of segments at a distant end. The encoded segment data is transmitted subsequently to the distant end.

摘要： A method and apparatus for image data compression includes detecting a portion of an image signal that uses a disproportionate amount of bandwidth compared to other portions of the image signal. The detected portion of the image signal result in determined components of interest. Relative to certain variance, the method and apparatus normalize the determined components of interest to generate an intermediate form of the components of interest. The intermediate form represents the components of interest reduced in complexity by the certain variance and enables a compressed form of the image signal where the determined components of interest maintain saliency. In one embodiment, the video signal is a sequence of video frames. The step of detecting includes any of: (i) analyzing image gradients across one or more frames where image gradient is a first derivative model and gradient flow is a second derivative, (ii) integrating finite differences of pels temporally or spatially to form a derivative model, (iii) analyzing an illumination field across one or more frames, and (iv) predictive analysis, to determine bandwidth consumption. The determined bandwidth consumption is then used to determine the components of interest.

摘要： A system and method is provided to transmit logmap video images through telephone line band-limited analog channels. The pixel organization in the logmap image is designed to match the sensor geometry of the human eye with a greater concentration of pixels at the center. The transmitter divides the frequency band into channels, and assigns one or two pixels to each channel, for example a 3 KHz voice quality telephone line is divided into 768 channels spaced about 3.9 Hz apart. Each channel consists of two carrier waves in quadrature, so each channel can carry two pixels. Some channels are reserved for special calibration signals enabling the receiver to detect both the phase and magnitude of the received signal. If the sensor and pixels are connected directly to a bank of oscillators and the receiver can continuously receive each channel, then the receiver needs not be synchronized with the transmitter.

摘要： In a transmission system for television signals of high temporal and spatial definition, the signals are subdivided into two components, in view of the limited band of the transmission channels, and transmitted by two separate channels. The first component constitutes a standard television signal and the second component constitutes a television signal of high spatial definition. The second signal component is a signal having the same high spatial definition as the input signal but low temporal definition. The transmission system so obtained is a high definition television compatible transmission system.

摘要： HDTV (12) and analog format compatible image communication (Fig. 1) is done in a single analog channel bandwidth. Luminance and chrominance image (10) data of a scene to be transmitted is obtained. The image data is quantized and digitally encoded to form digital image data in HDTV transmission format having low-resolution (16) terms and high-resolution terms (14). The low-resolution (16) digital image data terms are transformed to a voltage signal corresponding to analog format color subcarrier modulation with retrace blanking and color bursts to form an analog format video signal (22, 28). The analog format video signal and the high-resolution digital image data terms are then transmitted in a composite (24, 26) analog format video transmission (24).

摘要： Methods and systems for combatting degradation in the transmission or storage of data signals are disclosed, especially useful in the field of motion picture or television signal transmission, such that an advanced receiver can decode that information to provide improved picture quality, while a standard receiver will display an image with minimally visible impairments. In particular, the present invention discloses that a data signal can be decomposed by filter circuitry (42) and summer (46) into a low frequency signal and a high frequency signal, and that the high frequency signal can then be modified by the application of a series of scaling factors using an adaptive scaling element (48) over selected regions in response to local variance of data values in such regions. The low frequency signal and the modified high frequency signal are then combined and transmitted (or recorded) as a modulated facsimile of the data signal, together with the scaling factors. In the advanced receiver (or playback unit), the data signal is reconstructed from the modulated facsimile with concomittant reduuction in signal degradation by the application of a series of inverse scaling factors.
