2017-09-05media: intro.rst: don't assume audio and video codecs to be MPEG2Mauro Carvalho Chehab
Originally, when DVB was introduced, all codecs would be part of MPEG2 standard. That's not true anymore, as there are a large number of codec standards used on digital TV nowadays. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb uAPI docs: Prefer use "Digital TV instead of "DVB"Mauro Carvalho Chehab
The usage of the term "DVB" at the dvb API docs is confusing, as, right now, it can refer to either the European digital TV standard or to the subsystem. So, prefer calling it as "Digital TV" on most places, to avoid ambiguity. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: adjust the notices about optional hardwareMauro Carvalho Chehab
Both CA and decoders are optional. Also, the presence or absence has nothing to do on being a PCI card or not. Nowadays, most hardware leaves the decoders to either the GPU or to some ISP inside the SoC, instead of implementing it inside the Digital TV part of the device. So, change the wording to reflect the hardware changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: update the history part of the documentMauro Carvalho Chehab
Convergence doesn't exist anymore. The community itself maintains the spec. Update accordingly. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: update references for TV standardsMauro Carvalho Chehab
The references there are only for DVB. Add missing references for ATSC and ISDB standards. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: use the term Digital TV to refer to the systemMauro Carvalho Chehab
On several places at the introduction, a digital TV board and its kernel support is called as DVB. The reason is simple: by the time the document was written, there were no other digital TV standards :-) Modernize the specs by referring to them as Digital TV.

2017-08-27media: dvb/intro.rst: Use verbatim font where neededMauro Carvalho Chehab
The device numbering for DVB uses "M" and "N" as vars for the number of the device, but sometimes this is printed using normal font instead of verbatim. While here, remove an extra space after quotation marks. This is a minor cleanup with no changes at the text. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-03-13docs-rst: Don't use explicit Makefile rules to build SVG and DOT filesMauro Carvalho Chehab
Now that we have an extension to handle images, use it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-11-16docs-rst: auto-generate PDF image filesMauro Carvalho Chehab
The PDF files that contain media images were actually generated offline from their SVG or PNG source files. Sphinx can handle PNG sources automatially. So, let's just drop their PDF counterparts. For SVG, however, Sphinx doesn't produce the right tags to use the TexLive SVG support. Also, the SVG support is done via shell execution, with is not nice. So, while we don't have any support for SVG inside Sphinx core or as an extension, move the logic to build them to Makefile, producing the PDF images on runtime. NOTE: due to the way Sphinx works, the PDF images should be generated inside the Kernel source tree, as otherwise Sphinx won't find it, not obeying what's specified by "O=" makefile parameter.

2016-11-16convert some images from png to svgMauro Carvalho Chehab
SVG images are nicer, as they can easily be scaled. Also, they're written in text, with makes easier to work. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-07-08doc_rst: rename the media Sphinx suff to Documentation/mediaMauro Carvalho Chehab
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>
