From f9d79126195374c285035777b9d6abd24ceba363 Mon Sep 17 00:00:00 2001 From: Athanasios Oikonomou Date: Sat, 16 Dec 2017 07:23:38 -0500 Subject: media: dvb_frontend: add physical layer scrambling support This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX. This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.
