“…Considering high spatial correlation and time correlation of video signals, the number of slices in an FU is approximated to ëN SU /K SL l. Let K LU be the number of slices in an FU, then K LU is evaluated by Eq. (11). As shown in the appendix, since K LU is dominated by N LU in the case of transmitting video information at a mean rate of around 1.7 Mbps, the effect of this approximation on the analysis result will be small:…”

This paper discusses the use of cell interleaving (CI) to compensate for cell losses in VBR video transmission. To bound the delay due to CI, we propose a CI method with variable interleave unit length. Since the effectiveness (gain) of CI depends on the additional redundant information amount (redundancy) and delay, the optimum redundancy which maximizes the gain and the relation between the delay and the gain need to be studied. Thus, the gain of the proposed CI when it is applied to VBR video transmission is analyzed as a function of redundancy and delay tolerance. The analysis yields the following results: In the case where 50 VBR video sources are multiplexed, the tolerated delay should be larger than 20 ms to yield positive gain, and provided that tolerated delay is 33 ms (one video frame interval), the optimum redundancy is achieved at around 0.22 and the maximum gain is 0.091. The gain becomes smaller as more video sources are multiplexed. In case 200 sources are multiplexed, the gain is negative even if tolerated delay is 33 ms (one video frame interval). © 1998 Scripta Technica, Electron Comm Jpn Pt 1, 81(10): 81–90, 1998

“…RSE code [11] is used to generate FEC cells. With this RSE code, a communication channel code is made by adding a redundant component after the source information, and the length of source information (bytes) is equal to N SU and the length of the redundant component (bytes) is equal to N RU .…”

Summary This paper presents a performance study relative to the coupling of the Transmission Control Protocol (TCP) with the Contention Resolution Diversity slotted aloha (CRDSA) protocol, in the case of greedy TCP connections (also called elephants) on Digital Video Broadcasting-Return Channel via a geostationary satellite. CRDSA, which takes advantage of interference cancellation algorithms for collision/contention resolution, has already exhibited interesting performance when the power levels of all received bursts are perfectly balanced. In this paper, we extend the study to a more realistic case, where a certain spreading of the bursts' power levels is taken into account. The consequent capture effect even facilitates the collision resolution mechanism and yields an improvement in the overall TCP performance with respect to the balanced case. Furthermore, in certain conditions, the adoption of packet level forward error correction allows achieving even higher peaks of throughput than the expected ones

“…The scientific literature on FEC is huge. Since the concept of packet-level FEC was first coined by McAuley [28], enormous progress has been made, the focus being largely on the design and performance analysis of different types of codes: 1D [16,17,29] and 2D [30] block codes, convolutional codes [31], and various types of LDPC codes [12,14,32]. The code error correction capabilities, the achievable encoding/decoding throughputs, and the related computational requirements have been the benchmarks for the assessment and comparison of the codes in various application scenarios.…”

SUMMARYOne key aspect of digital multimedia broadcasting is the reliable point-to-multipoint distribution of content. Since the capacity and energy constraints in wireless environments do not favour the provision of a return channel for user feedback, the use of partial reliability techniques is often the only realistic option for the reliable transport layer design. In this paper, we focus on the two main reliable transport mechanisms in unidirectional, point-to-multipoint systems, namely packet-level forward error correction (FEC) and data carousels. We approach them as building components of an integrated scheme and investigate its performance via analytical means. Our analysis demonstrates that the network responsiveness, expressed by the average content access time, is optimized for certain packet-level FEC redundancy values. This is clearly different from setting FEC without considering the data carousel dimension, where the FEC redundancy is determined from the probability of recovering the whole file versus FEC overhead trade-off curves. We describe design alternatives for both scheme components, such as different FEC code types, rules for assigning FEC redundancy per carousel item, and ways to retrieve items from the data carousel, and evaluate their impact on the performance of the scheme. Our results suggest that the superposition of FEC on data carousels mitigates the otherwise significant impact of the data item retrieval technique on performance, at least for close-to-optimal FEC settings. On the contrary, the careful selection of FEC code and FEC redundancy assignment rule for data carousel items results in performance gains of up to 11 and 18% for the average content access time and FEC overhead, respectively, depending on the item demand and length distributions.
