I would like to know if my vision of things is correct about frame structure.

--------------------------------------------------------
Frame header
--------------------------------------------------------
Subframe1 header|Subframe1 content|
--------------------------------------------------------
 Subframe2 header|Subframe2 content|
--------------------------------------------------------
 Subframe3 header|Subframe3 content|
--------------------------------------------------------
 Subframe4 header|Subframe4 content|
--------------------------------------------------------

so.... like this:

----------------------------------------------------------------------------------
Wideband bit|Mode ID|LSP|OL pitch|
----------------------------------------------------------------------------------
Fine pitch1|Pitch gain1|Innovation gain1| Innovation VQ1|
----------------------------------------------------------------------------------
Subframe 1 content |
----------------------------------------------------------------------------------
Fine pitch2|Pitch gain2|Innovation gain2| Innovation VQ2|
----------------------------------------------------------------------------------
Subframe 2 content |
----------------------------------------------------------------------------------
Fine pitch3|Pitch gain3|Innovation gain3| Innovation VQ3|
----------------------------------------------------------------------------------
Subframe 3 content |
----------------------------------------------------------------------------------
Fine pitch4|Pitch gain4|Innovation gain4| Innovation VQ4|
----------------------------------------------------------------------------------
Subframe 4 content |
----------------------------------------------------------------------------------

next frame.... etc...

is that right?

Thanks.
