Clearly, you can only express this in SDP by providing two different m-lines, one for the send codec and one for the receive codecs. (Which you could bundle.) The problem that I see is that very few devices will be prepared to split sending and receiving of a video channel on different m-lines, they will be looking for one sendrecv m-line that they find acceptable. You might have one sendrecv m-line for H.264-BP and a separate recvonly m-line for H.264-HP. That maximizes the chance that the far-end UA will accept the SDP, but only my making it easy to use H.264-BP.
