From 9e615eac827094147401c44c9ff955b468d4fa79 Mon Sep 17 00:00:00 2001 From: Oliver Endriss Date: Wed, 3 Sep 2008 19:15:27 -0300 Subject: V4L/DVB (8889): dvb-ttpci: Support full-ts hardware modification Add support for the 'full-ts' hardware modification. On full-featured cards the data throughput is limited by the hardware design. The full-ts mod removes this bottleneck, i.e. the card is able to deliver the complete transport stream of a transponder.
