G.4 PSS client buffering requirements
26.2343GPPProtocols and codecsRelease 17Transparent end-to-end Packet-switched Streaming Service (PSS)TS
When the annex is in use, the PSS client shall be capable of receiving an RTP packet stream that complies with the PSS server buffering verifier when the RTP packet stream is carried over a constant-delay reliable transmission channel. Furthermore, the video decoder of the PSS client, which may include handling of post-decoder buffering, shall output frames at the correct rate defined by the RTP time-stamps of the received packet stream.
Annex H (informative):
Content creator guidelines for the synthetic audio medium type
It is recommended that the first element of the MIP (Maximum Instantaneous Polyphony) message of the SP-MIDI content intended for synthetic audio PSS/MMS should be no more than 5. For instance the following MIP figures {4, 9, 10, 12, 12, 16, 17, 20, 26, 26, 26} complies with the recommendation whereas {6, 9, 10, 12, 12, 16, 17, 20, 26, 26, 26} does not.
Annex I (informative):
Void
Annex J (informative):
Mapping of SDP parameters to UMTS QoS parameters
This Annex gives recommendation for the mapping rules needed by the PSS applications to request the appropriate QoS from the UMTS network (see Table J.1).

Delivery of erroneous SDUs |
"No" |

|
Maximum SDU size |
1400 bytes |
According to RFC 2460 the SDU size must not exceed 1500 octets. A packet size of 1400 guarantees efficient transportation. |

Guaranteed bit rate for downlink |
1.025 * session bandwidth |
This session bandwidth is calculated from the SDP media level bandwidth values. |
|
Maximum bit rate for downlink |
Equal or higher to guaranteed bit rate in downlink |
|
|
Guaranteed bit rate for uplink |
0.025 * session bandwidth |
|
|
Maximum bit rate for uplink |
Equal or higher to guaranteed bit rate in uplink |
