This paper introduces all-digital flexible channelizersand aggregators for multi-standard video distribution. The overall problem is to aggregate a number of narrow-band subsignals with different bandwidths (6, 7, or 8 MHz) into one composite wide-band signal. In the proposed scheme, this is carried out through a set of analysis filter banks (FBs), that channelize the subsignals into 1/2-MHz subbands, which subsequently are aggregated through one synthesis FB. In this way, full flexibility with a low computational complexity and maintained quality is enabled. The proposed solution offers orders-of-magnitude complexity reductions as compared with a straightforward alternative. Design examples are included that demonstrate the functionality, flexibility, and efficiency.
