摘要： The bandwidth required for a regularly occurring signal, such as a television signal, as received from a signal source can be substantially reduced by not transmitting each and every one of the horizontal scan lines. Rather, firstly, one or more selected lines may be transmitted and, secondly, instead of transmitting the remaining, unselected lines, a signal representing a predetermined arithmetic difference among predetermined ones of the scan lines may be transmitted. The bandwidth may be further reduced by a time expansion of the time interval of the selected line signal and by a time compression of the time interval of the differential signal. The bandwidth required for each regularly occurring signal as received from each of a plurality of N signal sources may be more efficiently used by time compression multiplexing the respective time expanded and time compressed signals.

摘要： Bandwidth is a precious resource in a communication system. High frequency signals, for example, video signals, typically require a relatively large bandwidth. One means for reducing bandwidth is by way of time compression multiplexing wherein signals may be stored a short period of time, compressed in time and then transmitted over a communication path. The subject signal processor may time compress and time synchronize an input signal with a time multiplexed signal. In a first arrangement, responsive to a time delay difference between the signals (215), a first frequency signal (220) is used to modulate (230) the input signal (210). The modulated signal is extended through a dispersive filter (260) for introducing a delay to the input signal, the delay for synchronizing same with the time multiplexed signal. The synchronized output of the dispersive filter may be extracted by an envelope detector (270) for extension to an output terminal (280). In a second arrangement, the input signal may be modulated by a variable chirp signal (220). The modulated (230) input signal is then extended through a dispersive filter (260) and an envelope detector (270) for jointly time compressing and time synchronizing the input signal with the time multiplexed signal.

摘要： The present invention relates to a Time Compression Multiplexing (TCM) technique for transmitting three consecutive television picture signals from a television picture source during the time period normally used to send one television picture signal. More particularly, three consecutive lines or fields from a TV signal source are compressed into an ordinary line or field period, respectively, by sending one line or field as is, but time compressed, in one portion of a line or field period and sending two other lines or fields as differential signals, also time compressed, to occupy two separate and different portions of the same line or field period as is used by the first one line or field. With such technique it is possible to send three consecutive line or field signals from each of three separate colocated or non-colocated TV sources on a Time Division Multiple Access (TDMA) basis.

摘要： The present invention relates to a technique for the synchronization of multiplexed television signals within each burst signals received at a remote station or satellite in a TDMA communication system from non-colocated ground stations. The technique employs a dynamic master/slave ground station arrangement where a first station signing on assumes the role of the master ground station. Other stations subsequently signing on synchronize their transmissions to the master station signal burst or the signal burst of the last station to sign on by using apparatus which monitors the received burst from the remote station, measures its own signal delay to the distant station and then phase-locks its local subcarrier clock to the master or last station's transmission burst. Dynamic transfer to the second station signing on occurs when the current master station terminates transmission for any reason.

摘要： A method and apparatus for reducing the output bit rate in a video object planes sequence encoder. An approximation of the shape of an object on a current frame is generated and used, along with a predicted image of the object from a subsequent frame and an estimate of the displacement of the object, to predict an image of the object in a current frame. A stripe is formed around the predicted image and the picture elements contained in the stripe are assigned texture values. The predicted image and stripe are subtracted from the current frame to form an error signal which is masked by the approximate shape of the object and provided to an entropy coder for transmission at an output bit rate.

摘要： A novel method and apparatus is disclosed for controlling inverse discrete cosine transform ("IDCT") mismatch between an encoder and decoder using different IDCT implementations under all coding conditions. Sychronization between the encoder and decoder is forced by selectively setting certain small DCT coefficients, which are prone to mismatch, to zero at the encoder. Advantageously, the invention may be implemented solely in the encoder to minimize system complexity and cost, and allow for IDCT mismatch control utilizing conventional decoders.

摘要： A video processing system is disclosed that separates and separately encodes and decodes the low and high spatial frequency coefficients of images for transmission or storage. Each block of an image is transformed into the frequency domain. High frequency coefficients of the resulting transform matrix are separated from the low frequency coefficients. The low frequency coefficients are motion prediction compensated to derive motion vectors and a prediction error signal. The motion vectors, prediction error signal and high frequency coefficients are channel encoded for storage or transmission. In a receiver, the motion vectors and prediction error signal are used to reconstruct a low frequency motion-compensated version of the image. The high frequency coefficients are inverse transformed into the pel domain and are combined with the reconstructed low frequency verison of the image to reconstruct a version of the original image.

摘要： The present invention relates to a technique for the Time-Frequency-Multiplexing (TFM) of three television signals. More particularly, three fields of a TV signal are sent simultaneously to a remote receiver by transmitting one field as is in the baseband of a standard television system signal while the other two fields are transmitted as differential signals, quadrature amplitude modulated onto a subcarrier frequency above baseband. The two differential signals can comprise two field differential signals or a frame and a field differential signal. Arrangements are also provided for transmitters and receivers for implementing the present technique.

摘要： A look-ahead system and method for pan and zoom detection in video sequences is disclosed. The system and method use motion vectors in a reference coordinate system to identify pans and zooms in video sequences. The identification of pans and zooms enables parameter switching for improved encoding in various video standards (e.g., H.264) and improved video retrieval of documentary movies and other video sequences in video databases or other storage devices.
