Robust transmission of 3D geometry over lossy networks

On-demand transmission of 3D models over lossy networks

“…In this section, we briefly discuss transmission systems that have been proposed in the literature [2][3][4][5][6][7][8][9]14,17,27]. According to the adopted errorresilient mechanism, these systems can be categorized into pre-processing, error correction, and transport-layer protocols.…”

“…Recently, hybrid TCP/UDP transport protocols such as 3TP have been proposed to stream 3D models [3,5,9]. The general idea is to send important data reliably using TCP and the remaining, less important, data using UDP.…”

“…In particular, to display 3D scenes on the user's terminal with satisfactory quality and in real time, the impact of packet losses and transmission delays on the decoding process need to be explored. Typically, reliable or error-resilient transmission can be achieved by pre-processing techniques such as data partitioning [7,17,27], post-processing techniques such as error-concealment, and networkoriented techniques such as forward error correction [2,6,4] and retransmission techniques [3,5,8,9,14]. All these techniques address efficient transmission of 3D data separately.…”

Latency-Minimized Delivery for Multi-Resolution Mesh Geometry

“…Given the RS codes (sχ, cχ), the packet-loss rate p and the round-trip time r, the steady-state transmission throughput T is described by (4), and τ sχ , τ cχ can be considered as constantvalue vectors. With the notations τ 0 = (τ sχ + τ cχ ) and τ0 = τs χ + τc χ = |τ 0| = 1 · τ 0, we have E(τs χ + τc χ |sχ, cχ) = E(τ0), and (6) is further expressed as…”
