    A Novel Mechanism for Delivering IPTV Traffic in Ethernet Passive Optical Networks

    IPTV offers digital television services over Internet Protocol (IP) for the ubscribers at a lower cost. Despite all the attractive IPTV services, it also requires high-speed access networks with the functions of multicasting, Quality-of-Services (QoS) guarantee and so on. In the access networks, Ethernet Passive Optical Network (EPON) is regarded as one of the best technology to meet the higher bandwidth demands applications such as IPTV. There are two common mechanisms used for delivering IPTV to the users in the EPON system such as, dedicated stream and multicast stream. The dedicated stream is not scalable to a large number of clients because of the limited bandwidth and resource consumption at the server side. Conversely, although multicast could be used as a scalable solution for media streaming, but providing such services in the EPON is still challenging due to some limitations in the EPON system. In this paper, we propose a new mechanism that is a Single Copy Broadcast (SCB) with Priority Queue (PQ) mechanism that can accommodate large number of clients IPTV streams without adding extra bandwidth and resources at the Optical Line Terminal (OLT). Simulation results have shown that our proposed mechanism can improve the QoS metrics and system performance in terms of bandwidth consumption and power consumption.Keywords— IPTV, QoS, EPON, Unicast, Multicast, Single Copy Broadcas

    Vision-based Detection of Acoustic Timed Events: a Case Study on Clarinet Note Onsets

    Acoustic events often have a visual counterpart. Knowledge of visual information can aid the understanding of complex auditory scenes, even when only a stereo mixdown is available in the audio domain, \eg identifying which musicians are playing in large musical ensembles. In this paper, we consider a vision-based approach to note onset detection. As a case study we focus on challenging, real-world clarinetist videos and carry out preliminary experiments on a 3D convolutional neural network based on multiple streams and purposely avoiding temporal pooling. We release an audiovisual dataset with 4.5 hours of clarinetist videos together with cleaned annotations which include about 36,000 onsets and the coordinates for a number of salient points and regions of interest. By performing several training trials on our dataset, we learned that the problem is challenging. We found that the CNN model is highly sensitive to the optimization algorithm and hyper-parameters, and that treating the problem as binary classification may prevent the joint optimization of precision and recall. To encourage further research, we publicly share our dataset, annotations and all models and detail which issues we came across during our preliminary experiments.Comment: Proceedings of the First International Conference on Deep Learning and Music, Anchorage, US, May, 2017 (arXiv:1706.08675v1 [cs.NE]

    Paper ini tentang kegiatan Pengabdian kepada Masyarakat yang dilakukan oleh penulis sebagai dosen pembimbing dari kelompok mahasiswa yang bernama Choir VoS. VoS singkatan dari Voice of Computer Science, adalah sebuah wadah yang dibuat oleh fakultas ilmu komputer untuk menampung dan membina mahasiswa yang memiliki talenta bernyanyi. Di sela-sela tugas belajar sebagai mahasiswa setiap anggota VoS harus memiliki komitment yang kuat dalam kelompok VoS. Komitmen itu seperti latihan, pelayanan dan berkegiatan sosial baik di dalam mupun di luar kampus. Penulis dan VoS mengadakan Pengabdian kepada Masyarakat di sebuah Sekolah Lanjutan Advent (SMP dan SMA) boarding school di Mebali kabupaten Tana Toraja Sulawesi Selatan. Kegiatan ini berlangsung selama 10 hari dengan agenda seminar tentang teknologi, pelatihan komputer dasar, diskusi kelompok, beribadah, dan pentas paduan suara. Kegiatan ini mengambil tema Live in Balance, senada dengan tujuan yang diharapkan yaitu menyeimbangkan kehidupan antara bekerja, belajar, beribadah dan bersosial. Hasil yang terlihat dalam PkM ini diantaranya peserta didik memahami peran siswa dalam menghadapi RI 4.0, peserta didik melek internet, juga guru dan siswa terisi kerohaniannya karena ada diskusi dan pentas lagu-lagu rohani. Jumlah peserta didik dan guru yang ikut berpartisapasi sekitar 200 orang

    A product is an artifact that mirroring the culture it expressed and also the changing agent of the same culture. In the case of consumerism, a product perform as a sign that is being manipulated for marketing communication. In Profanisation and Sacralization phenomenon the ideological identity that was formed in religion is now being contended in consumerism through the exploitation of the value of the sacred and the profane in an object. This research will be conducted in using marketing semiotic and ethnography to analyze the problem through the eye of the market. Based on the analysis and the review conducted, this research concludes a relation that links between a product design, religion and consumerism in the context of the phenomenon. This relation can be summed up as a market opportunity in faith-based design
