The video bandwidths used for defining MBR and GBR are assumed to be 192 kbps and 64 kbps, respectively. The IPv6 overhead is 16 kbps (assuming 15fps and 2 IP packets per frame) for MBR and 8 kbps (assuming 15fps and 1 IP packets per rame) for GBR, resulting in 208 kbps and 72 kbps, respectively. The transfer delay for video is different from other media. The applicable H.264 profile level can be derived from the "profile-level-id" MIME parameter signalled within the SDP "a=fmtp" attribute. H.264 receivers can request to receive only a lower bandwidth than depicted in this example via the SDP "b:AS" parameter.

Maximum SDU size (octets) | 1400 | Maximum size of IP packets |
Delivery of erroneous SDUs | No | |
Residual BER | 10-5 | Reflects the desire to have a medium level of protection to achieve an acceptable compromise between packet loss rate and speech transport delay and delay variation. |
SDU error ratio | 7*10-3 | A packet loss rate of 0.7 % per wireless link is in general sufficient for video services |
Transfer delay (ms) | 170 ms | Indicates maximum delay for 95th percentile of the distribution of delay for all delivered SDUs between the UE and the PS domain during the lifetime of a bearer service. Permits the derivation of the RAN part of the total transfer delay for the radio access bearer. This attribute allows RAN to set transport formats and H-ARQ/ARQ parameters such as the discard timer. |
Guaranteed bitrate for uplink (kbps) | 64 | The total bit-rate of a video codec (running at 40 kbps) adding IP/UDP/RTP overhead (assumed to be 2.4 kbps) and RTCP (adds 5 % of the session bandwidth) rounded up to nearest 8 kbps value.
If downlink SDP contains a lower b=AS bandwidth modifier value, this should be used instead. |
Maximum bitrate for uplink (kbps) | 704 | The total bit-rate of a video codec (running at 650 kbps) adding IP/UDP/RTP overhead (assumed to be 36 kbps) and RTCP (adds 5 % of the session bandwidth) rounded up to nearest 8 kbps value.
If downlink SDP contains a lower b=AS bandwidth modifier value, this should be used instead. |
Guaranteed bitrate for downlink (kbps) | 64 | The total bit-rate of a video codec (running at 40 kbps) adding IP/UDP/RTP overhead (assumed to be 2.4 kbps) and RTCP (adds 5 % of the session bandwidth) rounded up to nearest 8 kbps value.

If downlink SDP contains a lower b=AS bandwidth modifier value, this should be used instead. |
Allocation/Retention priority | subscribed value | Indicates the relative importance to other radio access bearers. It should be the same or next lower value to the priority of a Conversational bearer with source statistics descriptor 'speech'. |
Source statistics descriptor | 'unknown' | |
The video bandwidth is assumed to be 750 kbps and the IPv6 overhead 48 kbps (assuming 25 fps, 4 IP packets per frame and IPv6), resulting in 800 kbps. Adding 5% for RTCP increases the bandwidth by 40 kbps. However, the RTCP bandwidth is limited to max 14 kbps, see
clause 7.3.1. Rounding up to the next higher integer multiple of 8 kbps gives 816 kbps.

Guaranteed bitrate for uplink (kbps) | 816 | The total bit-rate of a video codec (running at 750 kbps) adding IPv6/UDP/RTP overhead (assumed to be 48 kbps) and RTCP (adds 5 %) rounded up to nearest 8 kbps value.
If downlink SDP contains a lower b=AS bandwidth modifier value, this should be used instead. |

The video bandwidths used for defining MBR and GBR are assumed to be 750 kbps and 40 kbps, respectively. The IPv6 overhead is 48 kbps (assuming 25 fps and 4 IP packets per frame) for MBR and 2.4 kbps (assuming QCIF, 5 fps and 1 IP packets per frame) for GBR, resulting in 800 kbps and 45 kbps, respectively. Adding 5% for RTCP increases the bandwidth by 40 kbps for both MBR and GBR. However, the RTCP bandwidth is limited to max 14 kbps, see
clause 7.3.1. Rounding up to the nearest higher integer multiple of 8 kbps gives 816 kbps and 72 kbps, respectively.
