“…Teknologi audio dan video merupakan salah satu topik penelitian yang berkembang dalam beberapa tahun belakangan ini. Tuntutan akan kualitas audio dan video yang tinggi melahirkan beberapa standarisasi baru, salah satunya Ultra High Definition Television (UHDTV) yang dikenal juga sebagai Super Hi-Vision [1]- [3]. Teknologi UHDTV telah yang distandarisasi oleh International Telecomunication Union (ITU) ini, menggunakan video dengan resolusi tinggi untuk menghasilkan gambar yang lebih jernih, sementara itu untuk meningkatkan kualitas audio digunakan konfigurasi audio multichannel 22.2 sehingga user dapat mendengar three-dimensional audio (3D-Audio) [4], [5].…”

Abstrak-MPEG Surround merupakan salah satu spatial audio coding yang populer digunakan. MPEG Surround umumnya digunakan pada bitrate rendah yaitu 64, 96, dan 160 kbps. MPEG Surround dapat digunakan pada bitrate tinggi, namun kualitas audio yang dihasilkan pada bitrate tersebut belum sepenuhnya diketahui. Paper ini menginvestigasi pengaruh kenaikan bitrate terhadap kenaikan kualitas audio. Hasil menunjukkan peningkatan kualitas audio yang cukup signifikan saat MPEG Surround digunakan pada bitrate tinggi. Dengan demikian MPEG Surround layak digunakan pada bitrate tinggi untuk mendapatkan kualitas audio yang lebih baik. Kata Kunci :Spatial Audio Coding dan MPEG SurroundAbstract-MPEG Surround is one of the spatial audio codings that popularly used. MPEG Surround is generally used at a low bitrate such as 64, 96 and 160 kbps. MPEG Surround can be used at high bitrates, but the audio quality produced in the bitrate is not yet fully known. This paper investigates the effect of increase bitrate toward the increase of audio quality. The result showed a significant increase of the audio quality when the MPEG surround used in high bitrate. Accordingly, the MPEG Surround eligible for use in high bitrate to get better audio quality.

“…The distribution of uncompressed data streams for film postproduction or critical scientific and medical applications requires up to 8 Gb∕s and 72 Gb∕s for 4K and UHD, respectively, [5,6]. For live video and video-on-demand (VoD) streaming applications, advanced compression technologies based on JPEG2000, H.264, and the more recent H.265 standard, can reduce these requirements to about 250 Mb∕s and 300-500 Mb∕s for 4K and UHD, respectively, [7][8][9]. In addition, there are requirements for the network to deliver stringent quality-of-service (QoS) to ensure high qualityof-experience (QoE) for users [10].…”

The emergence of beyond high definition digital media formats is a key driver for future networked media applications and services. The data transport and computational requirements of these emerging digital media formats are significantly greater than those of preexisting media formats. Therefore, there is the need to deploy high-end media processing and storage resources interconnected by high-performance optical networks. To this end, a service-oriented control framework is proposed to facilitate user context-, media-, and network-aware service provisioning. We investigate one of the principal functionalities of this framework: Joint scheduling of media and optical network resources. The immediate and advance user request models are presented. These models are applied to several proposed heuristic algorithms and mathematical formulations based on integer linear programming (ILP). These algorithms and ILPs are comparatively investigated by simulations. The results show that our algorithms and ILPs are able to facilitate high acceptance of user requests as well as effective and efficient use of available media and optical network resources.
