Abstract
Second images coded in a coded output video stream are generated for the visual display of image contents of first images coded in multiple coded input video streams, such that first coded image data of the coded input video streams are copied into second coded image data of the coded output video stream.

20. A method for establishing a coded output video stream from at least two coded input video streams, for joint representation of a first picture of each of the coded input video streams in a second picture of the coded output video stream, the coded output video stream and the coded input video streams having an identical color format, an identical bit resolution per coded pixel and an identical picture scanning, and are coded using an identical video coding method that has at least one coding mode in which second coded picture data describing the second picture of the coded output video stream can be divided into separable coded sub-picture data, comprising:
-
receiving the coded input video streams, each including first coded picture data and first signaling data, the first coded picture data in each case having picture information coded for the first picture; and producing the coded output video stream, including the second coded picture data, second control data and second signaling data, the second coded picture data being produced by copying one portion of the first coded picture data of first pictures to be shown simultaneously into one of the coded sub-picture data of the second picture, and the second signaling data being generated at least partly based on the first signaling data. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37)

36. A device for establishing a coded output video stream from at least two coded input video streams, for joint representation of a first picture of each of the coded input video streams in a second picture of the coded output video stream, the coded output video stream and the coded input video streams having an identical color format, an identical bit resolution per coded pixel and an identical picture scanning, and are coded using an identical video coding method that has at least one coding mode in which second coded picture data describing the second picture of the coded output video stream can be divided into separable coded sub-picture data, comprising:
-
means for receiving the coded input video streams, each including first coded picture data and first signaling data, the first coded picture data in each case having picture information coded for the first picture; and means for producing the coded output video stream, including the second coded picture data, second control data and second signaling data, the second coded picture data being produced by copying one portion of the first coded picture data of first pictures to be shown simultaneously into one of the coded sub-picture data of the second picture, and the second signaling data being generated at least partly based on the first signaling data.

38. At least one non-transitory computer readable medium storing at least two coded input video stream, each including first coded picture data and first signaling data, the first coded picture data in each case having picture information coded for the first picture, used for establishing a coded output video stream from the at least two coded input video streams, for joint representation of a first picture of each of the coded input video streams in a second picture of the coded output video stream, the coded output video stream and the coded input video streams having an identical color format, an identical bit resolution per coded pixel and an identical picture scanning, and are coded using an identical video coding method that has at least one coding mode in which second coded picture data describing the second picture of the coded output video stream can be divided into separable coded sub-picture data where the second coded picture data are produced by copying one portion of the first coded picture data of first pictures to be shown simultaneously into one of the coded sub-picture data of the second picture, and second signaling data are generated at least partly based on the first signaling data, each coded input video stream generated by a method comprising:
storing a signaling parameter indicating that a prediction for coding a first picture exclusively within a picture border of the first picture is carried out.
