“…The proposed method is tested under different packet loss rates between 5% and 30%. The results from the proposed methods are compared with our previous proposed method in [6] and the H.264/AVC slice group map type 'dispersed' and the suggested error concealment (EC) method. The simulation results are given for Foreman and News sequences.…”

“…When the threshold value is high, the extra cost introduced by MBAmap updating can be reduced greatly, as there is no extra coding required for most of the P frames. When the threshold = 1, the procedure is the same as the previous proposed method in [6]. The extra cost introduced also depends on the length of GOP and the type of video.…”

“…This is also referred as 'in frame' updating. Our previous proposed method in [6] is used for the MB classification. Fast Mode Decision and Early Skip Mode Decision [7] are applied to avoid encoding the whole frame and reduce the extra cost.…”

“…For both ways, the time and computational costs are very high as a whole encoding procedure is required to obtain the feature values for each MBAmap update. In our previous work [6], three features are chosen for the MB importance classification in a frame: Skip Mode, Rate-Distortion (RDcost) and MV. To avoid the extra cost introduced by updating the slice group map, the fast mode decision and early Skip mode decision are applied for the first encoding pass, and only the 16×16 MB mode is coded for the classification.…”

Slice group coding using Flexible Macroblock Ordering (FMO) based on Macroblock (MB) importance in H.264/AVC has been studied for providing higher error robustness in error prone environments. However, the efficiency still needs to be improved and the high computational and time cost it causes remains to be an issue. In this paper, an Adaptive Macroblock-to-slice Allocation map (MBAmap) Updating scheme is proposed based on our previous research work. The extra computational and time cost introduced is less than 10% compared to the conventional methods. The PSNR of the reconstructed video at the decoder side can be improved for up to 0.6dB compared to previous proposed method. A Slice Matching (SM) error concealment method is also introduced, which increases the PSNR for a further 0.2 to 0.4dB when applied with the slice group coding scheme.

“…This is done in [30], by assigning different importance to each macroblock and then using the Flexible Macroblock Ordering (FMO) mechanism of H.264/AVC to encode and transmit the more important slices with higher levels of error protection. Different types of multiple description coding [31] can also be used to improve the quality under transmission errors in multiple path networks [32].…”

Ahstract-This paper studies a method of enhancing QoE (Quality of Experience) in H.264-video and audio IP transmission by jointly applying FMO (Flexible Macroblock Ordering) and SCS (Switching between error Concealment and frame Skipping), which is a QoE-based video output scheme simply based on the receiver's operation. We conducted objective and subjective experiment on the method for combinations of two slice group map types (interleaved and dispersed), four contents and three picture patterns (I, 1+4P's and 1+14P's); we measured QoS (Quality of Service) and then assessed QoE in terms of the psychological scale. As a result, we find that for the patterns 1+4P's and 1+14P's, combinations of SCS and the dispersed map type work best, whereas for the pattern I, the frame skipping only (i.e., SCS without FMO) achieves the highest QoE.
