From 49965a80a4c4f5cbe15fb3bb1f8f8b0ec4ef02bc Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 19 Mar 2006 08:45:38 -0300 Subject: V4L/DVB (3581): Add new media/msp3400.h header containing the routing macros Moved msp3400.h to msp3400-driver.h. Created media/msp3400.h with the new routing defines and lots of comments.

You will have + to select which tuner input to use and which SCART input to use. The + selected tuner input, the selected SCART input and all I2S inputs go to + the DSP (the tuner input first goes through the demodulator). + + The DSP handles things like volume, bass/treble, balance, and some chips + have support for surround sound. It has several outputs: MAIN, AUX, I2S + and SCART1/2. Each output can select which DSP input to use. So the MAIN + output can select the tuner input while at the same time the SCART1 output + uses the I2S input. + + Outputs + ======= + + Most DSP outputs are also the outputs of the msp3400. However, the SCART + outputs of the msp3400 can select which input to use: either the SCART1 or + SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely + bypassing the DSP. + + Summary + ======= + + So to specify a complete routing scheme for the msp3400 you will have to + specify in the 'input' field of the v4l2_routing struct: + + 1) which tuner input to use + 2) which SCART input to use + 3) which DSP input to use for each DSP output + + And in the 'output' field of the v4l2_routing struct you specify: + + 1) which SCART input to use for each SCART output + + Depending on how the msp is wired to the other components you can + ignore or mute certain inputs or outputs. + + Also, depending on the msp version only a subset of the inputs or + outputs may be present.
