Protection of HEVC video delivery in vehicular networks with RaptorQ codes.

Piñol P, Martínez-Rach M, López O, Pérez Malumbres M - ScientificWorldJournal (2014)

Bottom Line: In this paper we focus on HEVC video coding standard streaming in vehicular networks and how it deals with packet losses with the aid of RaptorQ, a Forward Error Correction scheme.As vehicular networks are packet loss prone networks, protection mechanisms are necessary if we want to guarantee a minimum level of quality of experience to the final user.We have run simulations to evaluate which configurations fit better in this type of scenarios.

ABSTRACT
With future vehicles equipped with processing capability, storage, and communications, vehicular networks will become a reality. A vast number of applications will arise that will make use of this connectivity. Some of them will be based on video streaming. In this paper we focus on HEVC video coding standard streaming in vehicular networks and how it deals with packet losses with the aid of RaptorQ, a Forward Error Correction scheme. As vehicular networks are packet loss prone networks, protection mechanisms are necessary if we want to guarantee a minimum level of quality of experience to the final user. We have run simulations to evaluate which configurations fit better in this type of scenarios.

fig3: Bitrate (kbps) without FEC protection and with FEC protection for different symbol sizes, different protection windows, and different number of slices per frame (including RTP and fragmentation headers). (a) LP mode. (b) AI mode.

Mentions: In Figure 3, if you look at the curve labeled “without FEC,” you can see the bitrate value (not the percentage of increment) of the sequence for LP and AI modes. In LP mode the bitrates range from 64.9 kbps (1 slc/frm) to 90.9 kbps (26 slc/frm). In AI mode the bitrates range from 324.4 kbps (1 slc/frm) to 365.9 kbps (26 slc/frm). As we stated before in this section, the bitrate for mode LP is much lower than for AI mode; specifically, at 1 slice per frame the bitrate of LP mode is 5 times lower than AI's one.
