7.2.1. Size of the De-Interleaving Buffer

In either Offer/Answer or declarative Session Description Protocol (SDP) usage, the sprop-deint-buf-req media type parameter signals the requirement for the de-interleaving buffer size. Therefore, it is RECOMMENDED to set the de-interleaving buffer size, in terms of number of bytes, equal to or greater than the value of the sprop-deint-buf-req media type parameter.

When the SDP Offer/Answer model or any other capability exchange procedure is used in session setup, the properties of the received stream SHOULD be such that the receiver capabilities are not exceeded. In the SDP Offer/Answer model, the receiver can indicate its capabilities to allocate a de-interleaving buffer with the deint-buf-cap media type parameter. See Section 8.1 for further information on the deint-buf-cap and sprop-deint-buf-req media type parameters and Section 8.2.2 for further information on their use in the SDP Offer/Answer model.
