Definitions

  • CABAC codeword is terminated.
  • Fig. 4 shows the complete transcoding of two H.264 video streams
  • the parameter nC selects the corresponding VLC table depending on the number of coded coefficients in the adjacent blocks, i. Context-adaptive.
  • FIG. 4 shows the complete transcoding of video streams encoded according to the H.264 / AVC standard.
  • the two H.264 input video streams IS1 and IS2 from two subscribers are decoded by a respective H.264 video decoder VD1 and VD2 at the frame level.
  • the two video frames VF1 and VF2 are merged and merged to form a new video frame VF 'containing all the data of the individual video frames VF1 and VF2.
  • a new H.264 output video stream OS is encoded in the H.264 video encoder VE and sent to all
  • This process is also referred to as pixel domain mixing or full transcoding using e.g. a format conversion, a mixture of image data and the generation of a conference image is performed.
  • the macroblocks are assigned to the slices without additional aids.
  • the mixing of the video streams IS1 and IS2 takes place through a flexible allocation of the macroblocks to slice groups.
  • a slice group SGI and SG2 is defined for each of the two input video streams IS1 and IS1, which is then converted into a H.264 by the video mixer VM Output video stream OS are combined with the data of the two slice groups SGI and SG2.

Abstract

L'invention concerne un procédé et un dispositif permettant le mélange de flux vidéo dans un dispositif mélangeur vidéo qui réunit en un flux vidéo de sortie plusieurs flux vidéo d'entrée de plusieurs participants, qui sont codés avec des mots de code pour macro-blocs et dont les mots de code présentent des dépendances entre eux. A cet effet, les flux vidéo d'entrée sont soumis à un décodage entropique jusqu'à suppression des dépendances entre les mots de code, les macro-blocs étant de nouveau ordonnés et mélangés et les macro-blocs mélangés étant soumis à un codage entropique afin d'obtenir un nouveau flux vidéo dédié.
