“…Since descriptions will be sent through independent channels and any combination of received descriptions is decodable, network congestion or packet loss for some of the transmission channels will not interrupt the decoding process but only leads to a temporary degradation of decoding quality. Comparisons between FEC and MDC techniques [3], [4] indicated that one technique will outperform another under different transmission and packet loss rates.…”

This paper investigates the application of novel packet loss protection schemes to compress mixtures of speech sources for interactive real-time audio services such as spatial teleconferencing. Hybrid Forward Error Correction (FEC) and Multiple Description Coding (MDC) packet loss protection techniques are applied to the outputs of a psychoacoustic-based Analysis-By-Synthesis (PABS) coder designed for such applications. The protection approaches split the coder outputs into two descriptions that are separately protected using the hybrid FEC-MDC techniques. Perceptual Evaluation of Speech Quality (PESQ) measurements compare the performance of different protection schemes for a range of typical packet loss conditions. Results indicate the proposed scheme maintains the perceptual quality of the speech sources across a wide variety of packet loss conditions.

“…However, the generalization of such results to real-world data is not trivial, as MDC performance bounds are known not to be strict [15]. In [16], [17], a joint application of source channel coding and scalable MDC is proposed. From the reported results, worked out using Gaussian data, one can infer that methods using channel coding generally outperform MDC in matched transmission conditions.…”

In this letter, we present a performance comparison between multiple description coding (MDC) and unequal loss protection (ULP) for progressive image transmission over lossy packet networks. Two optimization criteria are considered, i.e., a multiquality criterion, when distinct quality levels are guaranteed at the decoder side, and the optimization of the expected quality at the receiver. We resort to both a semi-analytical approach and simulation results. To enable numerical comparisons, we address a specific MDC algorithm suitable for progressive imaging, and a state-of-the-art ULP algorithm based on Reed Solomon codes. The results, although cannot be generalized to any MDC and ULP methods, are useful to put into evidence some general features that can drive the selection of the most proper technique for the application at hand. In fact, they allow to put into evidence the main advantages and drawbacks of either technique.
