From f5174af201f2e22c101bb02d06343e4bc5f056de Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Mon, 26 Nov 2007 02:07:26 -0300 Subject: V4L/DVB (6698): pvrusb2: Implement signal routing schemes The exact routing of video and audio signals within a device is a device-specific attribute. Hauppauge devices do it one way; other types of device may route things differently. Unfortunately it is rather impractical to define chip-specific routing at the device attribute level, so instead what happens here is that "schemes" are defined. Each chip level interface implements its part of a given scheme and the scheme as a whole is made into a device specific attribute controlled via a table entry in pvrusb2-devattr.c. The only scheme defined here is for Hauppauge devices, but clearly this opens the door for other possibilities to follow.
