This paper investigates a given branch of the music information retrieval field, specifically that of audio thumbnail, through which a piece of music can be automatically summarized. We first provide a survey on the different techniques available today for the generation of music summaries, and then we propose a practical method that, based on best practices, is able to summarize songs with a great efficacy.

“…Fountain codes were also invoked in wireless networks to protect file transfer by considering 802.11 Media Access Control (MAC) retransmission rate in [3]. Due to the expense of redundancy, it was observed that fountain codes can improve the performance of data transmission only when considering the actual application environment in [4]. Carefully selecting the payload length is useful aid in practical fountain codes system in [5].…”

Abstract. Video transmission over wireless multi-hop networks is challenging due to the varying nature of the wireless channel as well as the inherent difference between the video data traffic and the general data traffic. A single bit error in a packet may lead to the packet loss, which results in poor quality of the entire video frame. In this paper, we first analyze the effect of payload length on the overhead of bit error, video frame reassembly and network efficiency. Then, to improve the quality of video transmission, we propose an adaptive payload length algorithm based on the digital fountain codes while take transmission efficiency into account. The simulation environment is also designed to evaluate the performance of multi-hop video transmission, which is based on the ARM embedded system. Numerical simulations show that adaptive payload length algorithm can improve the quality of video transmission over wireless multi-hop networks.

“…A distinctive feature of these codes is their inherent ability to average out varying channel conditions by decreasing the encoding rate until the successful data delivery [2]. The efficiency of the LT codes can be further enhanced by combining the LT codes and the forward error correction (FEC) codes [3]. For example, the raptor codes pre-code the data with the FEC codes to increase the error resilience of the fountain codes.…”

The fountain codes are attractive for efficient multicast delivery of large data or multimedia files over unreliable wireless channels. These codes are standardized and intended to operate at the application layer. In this paper, the fountain codes are incorporated into the LTE protocol stack at the medium access (MAC) layer. It is shown that the MAC layer implementation of the fountain codes requires that not only the LTE parameters are optimized, but also, that the adaptive modulation and coding (AMC) scheme mechanism is modified. Provided that such optimization and modifications are adopted, for instance, in the LTE-Advanced, the MAC layer fountain codes can significantly outperform the application layer fountain codes in terms of the energy consumption-transmission delay trade-off.
