“…In video delivery, the packet loss and jitter that occur in transmission significantly affect the video quality; consequently, functions to suppress them are necessary for real-time video streaming. NTT Network Innovation Laboratories has been studying a 4K video, low-latency transmission system [1]. We have developed Internet Protocol (IP) packet compensation technology that uses application layer forward error correction (AL-FEC) and achieves highly reliable IP transmission.…”

This paper introduces a FireFort-LDGM (FF-LDGM) code that is part of ISO/IEC 23008-10 (MMT AL-FEC codes) and its application to robust Ultra High Definition (UHD) video transmission. It is especially useful for UHD real-time video streaming because that it can easily handle contiguous streams containing over several thousand packets. Simulation results show its high error recovery performance with lowcomplexity. We also show a robust UHD video transmission scheme that uses the FF-LDGM code and its feasibility via 8K Super High-Vision live streaming over global shared IP networks at FIFA World Cup 2014 Brazil.

“…The rapid adoption of the features in the new 8K and 4K (i.e. 4096x2160 pixels) imaging systems used in digital cinema, live streaming, and networked super-tele-presence systems for remote collaboration has motivated the need for real-time DSP sustaining a total bit rate exceeding 12Gbps [2]. The recently introduced High Efficiency Video Coding (HEVC) standard is a video compression format that effectively doubles the data compression rate compared to H.264/MPEG-4 AVC at the same level of video quality.…”

This paper investigates VLSI architectures for digital processing (DSP) functions amenable to low energy operation with scalable performance for H.265 high efficiency video coding (HEVC) applications. First, we describe and experimentally evaluate a novel adaptive computing fabric. Second, we propose an energy-efficient method to scale the performance of the fabric for large images or for meeting stringent real-time computation requirements. A series of tradeoffs for exploiting efficiently the application space for general purpose DSP acceleration are proposed. We experimentally show how the proposed computing fabric is reusable for Filters, FFT and DCT acceleration with a scalable throughput. We report on the design and implementation of the fabric on a Xilinx FPGA device and show how regulatedparallelism augmented with in-memory processing techniques impact performance and power efficiency. The FPGA prototype demonstrates a sustained throughput exceeding 10Gbps irrespective of the kernel and image size for H.265 HEVC applications.

“…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].…”

“…There are also corresponding high computational and storage requirements which are far greater than those for HD and other preexisting formats. For example, a two hour 4K video that is compressed to 250 Mb∕s will require about 200-300 GB of storage capacity [9].…”

“…A number of works have proposed optical transmission systems for DC and UHD television broadcasting applications [6,9]. However, these works have focused on the implementation and trial of novel encoder/decoder (codec) and streaming systems, and not on the design of architectures for end-to-end delivery of networked media services using 4K and UHD.…”

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.
