摘要

The method involves transmitting the data in a region lying between the last row or column occupied by test or data signals and a predefined row or column of the image signal. The data can be transmitted in the image signal, e.g. in an edge region or both vertical edge regions of the image signal, especially in a spatial arrangement like one or more columns.
