“…We used the same set of parameters for the CRC parity checker and RCPC channel coder 10,7,8 : N = 200, c = 16, and m = 6. We focused on bit error rates (BER) of = 0.01 and 0.001, because the BER's of most wireless communication channels are = 0.01 -0.001.…”

“…To achieve robust video over noisy channels, the work of Sherwood and Zeger 5,6 was extended to progressive video coding by Kim et al They have shown in Ref. 7,8 that the robustness is increased when we cascade the 3-D SPIHT coder with rate-compatible punctured convolutional (RCPC) channel coder 9 and automatic repeat request (ARQ) to protect the 3-D SPIHT bitstream from being corrupted by channel errors. This approach increases robustness, but is still susceptible to early decoding failure.…”

This paper presents an unequal error protection of embedded video bitstreams using three dimensional SPIHT (3-D SPIHT) algorithm and Spatio-Temporal Tree Preserving 3-D SPIHT (STTP-SPIHT) algorithm. We have already proved the efficiency and robustness of the STTP-SPIHT in both of noisy and noiseless channels by modifying the 3-D SPIHT algorithm. We demonstrate that the 3-D SPIHT can also be error resilient against channel bit errors by dividing the embedded video bitstreams, and more error resilient when we divide the STTP-SPIHT bitstreams.

“…To achieve robust video over noisy channels, Kim et al 10 utilized the same RCPC code as Sherwood and Zeger 6,7 with 3D SPIHT, and found that a single automatic repeat request(ARQ) was also necessary to adequately protect the bit stream. ARQ, however, may not be feasible in certain scenarios and has the unfortunate consequence of increasing traffic on already congested channels.…”

Compressed video bitstreams require protection from channel errors in a wireless channel and protection from packet loss in a wired ATM channel. The three-dimensional (3-D) SPIHT coder has proved its efficiency and its real-time capability in compression of video. A forward-error-correcting(FEC) channel (RCPC) code 1 combined with a single ARQ (automatic-repeat-request) proved to be an effective means for protecting the bitstream. There were two problems with this scheme: the noiseless reverse channel ARQ may not be feasible in practice; and, in the absence of channel coding and ARQ, the decoded sequence was hopelessly corrupted even for relatively clean channels. In this paper, we first show how to make the 3-D SPIHT bitstream more robust to channel errors by breaking the wavelet transform into a number of spatio-temporal tree blocks which can be encoded and decoded independently. This procedure brings the added benefit of parallelization of the compression and decompression algorithms. Then we demonstrate the packetization of the bit stream and the reorganization of these packets to achieve scalability in bit rate and/or resolution in addition to robustness. Then we encode each packet with a channel code. Not only does this protect the integrity of the packets in most cases, but it also allows detection of packet decoding failures, so that only the cleanly recovered packets are reconstructed. This procedure obviates ARQ, because the performance is only about 1 dB worse than normal 3-D SPIHT with FEC and ARQ. Furthermore, the parallelization makes possible real-time implementation in hardware and software.

“…They then apply Kim's method [13] [14] of RCPC channel coding as the forward-error correction (FEC) to every packet to protect the data. It is interesting to note that the scheme proposed in [15] could be used inline with any error-resilient coding method to alleviate the effect of error propagation by adding some periodic macroblocks in every fifth inter-frames.…”

Abstract-Video transmission over the wireless or wired network require protection from channel errors since compressed video bitstreams are very sensitive to transmission errors because of the use of predictive coding and variable length coding. In this paper, a simple, low complexity and patent free error-resilient coding is proposed. It is based upon the idea of using spatial partitioning on the motion compensated residual frame without employing the transform coefficient coding. The proposed scheme is intended for open source Dirac video codec in order to enable the codec to be used for Internet broadcasting. By partitioning the wavelet transform coefficients of the motion compensated residual frame into groups and independently processing each group using arithmetic coding and Forward Error Correction (FEC), robustness to transmission errors over the packet erasure wired network could be achieved. Using the Rate Compatibles Punctured Code (RCPC) and Turbo Code (TC) as the FEC, the proposed technique provides gracefully decreasing perceptual quality over packet loss rates up to 30%. The PSNR performance is much better when compared with the conventional data partitioning only methods. Simulation results show that the use of multiple partitioning of wavelet coefficient in Dirac can achieve up to 8 dB PSNR gain over its existing un-partitioned method.
