Patent ID: 11902617
Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. A source device that generates a multistream signal including content streams transmitted to a plurality of sink devices that are connected by daisy-chaining, wherein
the source device is configured to generate the multistream signal by associating daisy chain stage numbers of the sink devices with the content streams for the sink devices based on a tiling pattern and a tiling location of each of the sink devices, the generated multistream signal including the daisy chain stage numbers and the content streams,
wherein the source device is further configured to
obtain the tiling pattern and the tiling locations from the sink devices,
estimate the tiling pattern and the tiling locations of the sink devices,
associate, as first content streams, a plurality of tile data items that are obtained by dividing a test pattern, which is a first display content, with the daisy chain stage numbers of the sink devices, respectively, and generate and transmit a first multistream signal including the first content streams and the daisy chain stage numbers associated with the first content streams, and
compare a second display content, which is displayed by the sink devices based on the received first multistream signal, with the test pattern to estimate the tiling pattern and the tiling locations of the sink devices.
