Is There a Sed Solution for This?

Hi All,

I'm trying to use sed to extract data within a String, but I'm having problems with sed command:

Text:
STATUS OSRC_R6_0_MENT_R1H_CU M_901662 R1H_LV1_20080313

Based from the Text above, I just need to extract this data
R6_0
R1H_CU
LV1

Is there a solution for this in sed?

Thanks a lot in advance.

For instance:
(a) looking for something beginning at position 13
(b) looking for something after "OSRC_"
(c) the next four characters - getting the "R6_0"
(d) next two parameters separated by delimiter "_"

Perhaps a longer sample input and desired outputs.
