Stream to Tagged Stream

Converts a regular stream into a tagged stream.

All this block does is add length tags in regular intervals. It can be used to connect a regular stream to a gr::tagged_stream_block.

This block is meant to be connected directly to a tagged stream block. If there are blocks between this block and a tagged stream block, make sure they either don't change the rate, or modify the tag value to make sure the length tags actually represent the packet length.

Parameters

(R): Run-time adjustable

Packet length (R)

Number of items per tagged stream packet. One tag is written every Packet length items and contains that number.

Length Tag Key

Key of the length tag.
