<p>The transmission method involves having the digital image signal parts transmitted via a number of partial transmission channels (1,2,3) with the higher hierarchy channels having a lower error rate than the lower hierarchy channels. A part of the digital signal, which is logically associated with a lower hierarchy channel, is transmitted in a higher hierarchy channel. The channel with the highest transmission quality can be used for transmission of the digital video signals (TV), and the lower quality channels (2,3) can be used for transmission of the additional data (HD1,HD2) used for increasing the definition of the video images.</p> |
