Definitions

  • the invention relates to a method for storing or transmitting stereoscopic video signals that contain a left video signal and a right video signal.
  • two different camera positions are recorded, the signals from both cameras - hereinafter referred to as left and right video signals - are transmitted, and the reproduction is such that the eyes of a viewer are each taken from one of the positions See picture.
  • two channels or a channel with double bit rate are required for the video signals without further measures.
  • left and right video signals are under-sampled after pre-filtering and combined with one another using a time-division multiplex method
  • the combined signal is encoded in a data-reducing manner and decoded after transmission or storage
  • every second sample is forwarded during the sub-sampling.
  • the method according to the invention has the advantage that the stereoscopic video signals are encoded in a common data stream that can be transmitted and stored in the usual way.
  • a further development of the method according to the invention consists in the fact that when the video signals are present using the interline method, the subsampling in the two partial images takes place so differently that a quincunx pattern results in the full image.
  • This further development has the advantage that the horizontal and vertical resolution is almost retained.
  • the combined signal alternates the left and the right video signal line by line contains.
  • this development has the advantage that the devices provided for data-reducing coding and decoding can also be used for the signals combined according to the method of the invention without significant changes.
  • Data-reducing processing steps such as discrete cosine transformation, are thus successively applied to one line of the left image and one line of the right image.
  • An advantageous embodiment of the method according to the invention consists in that each component signal is undersampled when the video signals are present as component signals. This ensures that the component signals are also processed in the same way, so that falsifications of the color tone or the color strength are avoided.
  • the method according to the invention can be used per se in connection with various data reduction methods. However, it is preferably provided that the data-reducing coding is carried out using the MPEG method.
  • Fig. 1 is a schematic representation of the signals occurring during the various steps of the method
  • Fig. 2 is a block diagram for explaining the method according to the invention.
  • the left and right video signals to be transmitted or stored are digitally available in accordance with the ITU-R 601 YUV 4: 2: 2 standard.
  • a line of the luminance signal Y accordingly contains 720 picture elements or samples, while the color difference signals U and V each contain 360 samples per line. 576 lines form a full picture, the sub-pictures containing 288 lines.
  • the inputs 1, 2 are supplied with the video signals YL, UL and VL of the left channel and YR, UR and VR of the right channel to be transmitted or stored. To avoid alias interference during the subsequent subsampling, these signals are pre-filtered at 3 and 4.
  • the pre-filtered signals are subsampled at 5, 6, which is done in such a way that every second picture element is forwarded, the picture elements to be forwarded preferably being offset from field to field by the width of one pixel in each case.
  • This is shown schematically in FIG. 2 with reference to 9 picture elements, the picture elements of the upper and the lower line belonging to a first partial picture and the picture elements of the middle line belonging to a second partial picture.
  • the crossed out picture elements are suppressed in the subsampling. With the number of lines remaining the same, the number of picture elements per line is halved, which is shown in FIG. 1 in diagrams 7 and 8.
  • the undersampled video signals are combined in a multiplexer 9 to form a signal which is fed from the output 10 of the multiplexer 9 to a coder 11.
  • the data-reduced combined signal generated by the encoder 11 is then passed via a channel 12 (transmission channel, recording and reproducing channel) to a decoder 13, from the output of which it is led to a demultiplexer 14, at the outputs 15 and 16 of which the undersampled left and right Video signals are available.
  • a picture element with the value 0 is inserted between every second picture element of the subsampled signals, whereupon at 19 and 20 the picture elements initially used with the value 0 receive values which are determined by interpolation of the neighboring picture elements.
  • the left and right video signals YL, UL, VL and YR, UR and VR are then available at the outputs 21, 22.

Abstract

Procédé pour la mémorisation ou le transfert de signaux vidéo stéréoscopiques présentant un signal vidéo gauche et un signal vidéo droit, caractérisé en ce que le signal vidéo gauche le signal vidéo droit sont sous-échantillonnés après préfiltrage et combinés mutuellement suivant un processus de multiplexage dans le temps, le signal combiné est codé avec réduction des données, puis décodé après transfert ou mémorisation, le signal combiné décodé est de nouveau réparti en un signal vidéo gauche et en un signal vidéo droit, et en ce que les valeurs échantillonnées perdues par le sous-échantillonnage sont remplacées par des valeurs échantillonnées interpolées. Pour la réduction des données, on utilise de préférence un codage conforme au procédé MPEG.
