MEMBANGUN SERVER STREAMING MULTIMEDIA PADA PT MULTI INDOSARVA SEJATI CABANG SURAKARTA

Haris Pujianto, 2010, MEMBANGUN SERVER STREAMING MULTIMEDIA PADA PT MULTI INDOSARVA SEJATI CABANG SURAKARTA Sebagian besar pengguna internet khususnya di warnet atau game center sangat menggemari multimedia streaming. Agar dapat mengakses multimedia streaming dengan lancar, pengguna memerlukan bandwidth yang cukup besar. Selain itu jumlah hops yang sedikit dalam jaringan juga memperlancar akses streaming. Tentu saja hal ini menjadi kendala bagi pengguna yang memiliki bandwidth yang terbatas dan jumlah hops yang banyak dalam jaringannya. Untuk menyediakan layanan multimedia streaming, dibutuhkan suatu komputer dengan sistem operasi dan aplikasi khusus yang dinamakan Server Streaming Multimedia. Selain menyediakan layanan streaming , server ini juga digunakan untuk memanajemen segala aktivitas multimedia streaming termasuk manajemen user, file storage, dan juga media encoder dengan suatu aplikasi PHPMotion. Dengan adanya server streaming multimedia sendiri dalam suatu perusahaan atau ISP (Internet Service Provider), diharapkan mampu menjawab permasalahan yang dihadapi para pengguna khususnya dalam ruang lingkup client perusahaan atau ISP PT Multi Indosarva Sejati cabang Surakarta dalam mengakses multimedia streaming.

Design of a middleware for QoS-aware distribution transparent content delivery

Developers of distributed multimedia applications face a diversity of multimedia formats, streaming platforms and streaming protocols. Furthermore, support for end-to-end quality-of-service (QoS) is a crucial factor for the development of future distributed multimedia systems. This paper discusses the architecture, design and implementation of a QoS-aware middleware platform for content delivery. The platform supports the development of distributed multimedia applications and can deliver content with QoS guarantees. QoS support is offered by means of an agent infrastructure for QoS negotiation and enforcement. Properties of content are represented using a generic content representation model described using the OMG Meta Object Facility (MOF) model. A content delivery framework manages stream paths for content delivery despite differences in streaming protocols and content encoding. The integration of the QoS support, content representation and content delivery framework results in a QoS-aware middleware that enables representation transparent and location transparent delivery of content

Saving Energy in Mobile Devices for On-Demand Multimedia Streaming -- A Cross-Layer Approach

This paper proposes a novel energy-efficient multimedia delivery system called EStreamer. First, we study the relationship between buffer size at the client, burst-shaped TCP-based multimedia traffic, and energy consumption of wireless network interfaces in smartphones. Based on the study, we design and implement EStreamer for constant bit rate and rate-adaptive streaming. EStreamer can improve battery lifetime by 3x, 1.5x and 2x while streaming over Wi-Fi, 3G and 4G respectively.Comment: Accepted in ACM Transactions on Multimedia Computing, Communications and Applications (ACM TOMCCAP), November 201

MEMBANGUN SERVER STREAMING MULTIMEDIA PADA PT MULTI INDOSARVA SEJATI CABANG SURAKARTA

Haris Pujianto, 2010, BUILDING MULTIMEDIA STREAMING SERVER ON PT MULTI INDOSARVA SEJATI BRANCH SURAKARTA The majority of internet users especially in internet cafe or game center are very fond multimedia streaming. Users need a large enough bandwidth to access the multimedia streaming smoothly. A few of hops in the network stream also expedite access to stream. Of course this is an obstacle for users who have limited bandwidth and a lot of hops in their network. To provide multimedia streaming service, we need a computer with the special operating system and application called Multimedia Streaming Server. In addition to providing streaming service, this server is also used for managing all activities of the multimedia streaming including user management, file storage, and also media encoder with an application that called PHPMotion. By the own multimedia streaming server in a company or ISP (Internet Service Provider), it was that expected to the system be able to answer the problems faced by users, especially within the scope of PT Multi Indosarva Sejati branch Surakarta clients in accessing multimedia streaming.

Region of interest-based adaptive multimedia streaming scheme

Adaptive multimedia streaming aims at adjusting the transmitted content based on the available bandwidth such as losses that often severely affect the end-user perceived quality are minimized and consequently the transmission quality increases. Current solutions affect equally the whole viewing area of the multimedia frames, despite research showing that there are regions on which the viewers are more interested in than on others. This paper presents a novel region of interest-based adaptive scheme (ROIAS) for multimedia streaming that when performing transmission-related quality adjustments, selectively affects the quality of those regions of the image the viewers are the least interested in. As the quality of the regions the viewers are the most interested in will not change (or will involve little change),the proposed scheme provides higher overall end-user perceived quality than any of the existing adaptive solutions

QoE-centric management of advanced multimedia services

Over the last years, multimedia content has become more prominent than ever. Particularly, video streaming is responsible for more than a half of the total global bandwidth consumption on the Internet. As the original Internet was not designed to deliver such real-time, bandwidth-consuming applications, a serious challenge is posed on how to efficiently provide the best service to the users. This requires a shift in the classical approach used to deliver multimedia content, from a pure Quality of Service (QoS) to a full Quality of Experience (QoE) perspective. While QoS parameters are mainly related to low-level network aspects, the QoE reflects how the end-users perceive a particular multimedia service. As the relationship between QoS parameters and QoE is far from linear, a classical QoS-centric delivery is not able to fully optimize the quality as perceived by the users. This paper provides an overview of the main challenges this PhD aims to tackle in the field of end-to-end QoE optimization of video streaming services and, more precisely, of HTTP Adaptive Streaming (HAS) solutions, which are quickly becoming the de facto standard for video delivery over the Internet

Streaming Audio and Media at Different Electronic Devices

A content streaming system can be used for streaming audio and video of a multimedia content at different electronic devices. The content streaming system receives an instruction to play video of a multimedia content at a first electronic device. The system then determines whether to play audio of the multimedia content at a second electronic device which is capable of audio output. Accordingly, the system streams the audio of the multimedia content to the second electronic device and the video of the multimedia content to the first electronic device

CliqueStream: an efficient and fault-resilient live streaming network on a clustered peer-to-peer overlay

Several overlay-based live multimedia streaming platforms have been proposed in the recent peer-to-peer streaming literature. In most of the cases, the overlay neighbors are chosen randomly for robustness of the overlay. However, this causes nodes that are distant in terms of proximity in the underlying physical network to become neighbors, and thus data travels unnecessary distances before reaching the destination. For efficiency of bulk data transmission like multimedia streaming, the overlay neighborhood should resemble the proximity in the underlying network. In this paper, we exploit the proximity and redundancy properties of a recently proposed clique-based clustered overlay network, named eQuus, to build efficient as well as robust overlays for multimedia stream dissemination. To combine the efficiency of content pushing over tree structured overlays and the robustness of data-driven mesh overlays, higher capacity stable nodes are organized in tree structure to carry the long haul traffic and less stable nodes with intermittent presence are organized in localized meshes. The overlay construction and fault-recovery procedures are explained in details. Simulation study demonstrates the good locality properties of the platform. The outage time and control overhead induced by the failure recovery mechanism are minimal as demonstrated by the analysis.Comment: 10 page
