doc_rst: rename the media Sphinx suff to Documentation/media
The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

+
+DVB-C delivery system
+=====================
+
+The DVB-C Annex-A is the widely used cable standard. Transmission uses
+QAM modulation.
+
+The DVB-C Annex-C is optimized for 6MHz, and is used in Japan. It
+supports a subset of the Annex A modulation types, and a roll-off of
+0.13, instead of 0.15
+
+The following parameters are valid for DVB-C Annex A/C:
+
+- :ref:`DTV_API_VERSION <DTV-API-VERSION>`
+
+- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>`
+
+- :ref:`DTV_TUNE <DTV-TUNE>`
+
+- :ref:`DTV_CLEAR <DTV-CLEAR>`
+
+- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>`
+
+- :ref:`DTV_MODULATION <DTV-MODULATION>`
+
+- :ref:`DTV_INVERSION <DTV-INVERSION>`
+
+- :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>`
+
+- :ref:`DTV_INNER_FEC <DTV-INNER-FEC>`
+
+- :ref:`DTV_LNA <DTV-LNA>`
+
+In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
+are also valid.

+
+DVB-C Annex B delivery system
+=============================
+
+The DVB-C Annex-B is only used on a few Countries like the United
+States.
+
+The following parameters are valid for DVB-C Annex B:
+
+- :ref:`DTV_API_VERSION <DTV-API-VERSION>`
+
+- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>`
+
+- :ref:`DTV_TUNE <DTV-TUNE>`
+
+- :ref:`DTV_CLEAR <DTV-CLEAR>`
+
+- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>`
+
+- :ref:`DTV_MODULATION <DTV-MODULATION>`
+
+- :ref:`DTV_INVERSION <DTV-INVERSION>`
+
+- :ref:`DTV_LNA <DTV-LNA>`
+
+In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>`
+are also valid.
