This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Energy descramble

ETSI EN 300 744 - Clause 4.3.1.

Input
Randomized MPEG-2 transport packets.
Output
MPEG-2 transport packets (including sync - 0x47).

We assume the first byte is a NSYNC. First sync in a row of 8 packets is reversed - 0xB8. Block size is 188 bytes.

Parameters

Blocks
number of blocks.

Example Flowgraph

This flowgraph can be found at [1].
