(1.7) D9.4 Revised Requirement Analysis

The integrated project “LIVE Staging of Media Events” (LIVE; FP6-27312) aims at the creation of novel intelligent content production methods and tools for interactive digital broadcasters to stage live media events in the area of sports, such as the 2008 Olympic Games. This report provides the revised requirements analysis based on the requirements formulated by users and based on the evaluation of the 1st prototype. The requirements outlined throughout this document give an overall view of the LIVE production support system. Some of them are already known and also stated in [LIVE D9.1]. Due to the limited amount of user tests and evaluation results, the initial requirements were mainly driven by technical issues whereas this document aims to be more users centric in the way that the results of the user tests and evaluation phase have been used to describe user scenarios of the dedicated LIVE users. The LIVE production support system comprises an overall system designed to support not only the real LIVE production of the show but also the entire life cycle of broadcasters including the preparation, production and post-processing of a show. To complete the production life cycle, post-processing of a show has been examined and is supported mainly by providing storage functionality for information created during production for later usage. The requirements analysis given in this document is mainly driven by the user scenarios outlined in chapter 3. These scenarios are mainly concerned with the different phases of the production life cycle. The scenarios are related to the distinct users dealing with the LIVE production support system. Based on the user scenarios, chapter 4 lists requirements for the entire system by concentrating on the tools to provide the required functionality to the mentioned users. As a result, a list of tools is given, which all together comprise the LIVE production support system. These tools are divided into four main groups: The first group covers tools of the so called Management Space covering the pre-production and post-processing as well as all kinds of management tasks. The remaining three groups match with the already known LIVE user spaces called the Annotation Space, the Editor Space and the Consumer Space. This chapter is to be seen as a technical reference suitable to verify the fulfilment of the requirements during the implementation phase. Chapter 5 gives a technical description of the use cases which again is used as a technical reference. The template used when creating the use cases is provided in Appendix A. Finally, chapter 6 provides a conclusion where all the raised issues are again collected and hints with respect to the architecture are given.

(1.7) D9.5 Revised System Architecture

The integrated project “LIVE Staging of Media Events” (LIVE; FP6-27312) aims at the creation of novel intelligent content production methods and tools for interactive digital broadcasters to stage live media events in the area of sports, such as the 2008 Olympic Games. This report presents the revised system architecture based on the revised requirements analysis given in [LIVE D9.4] and the evaluation of the 1st prototype. The revised system architecture is presented on a component-based level with the respective interfaces. This document does not make assumptions on the implementation techniques. The LIVE production support system comprises an overall system designed to support the entire life cycle of live staging including the preparation, production and post-processing of a show. Chapter 3 presents the observed workflows for all three phases. It picks up the already defined workflows from [LIVE D9.2] and adapts and amends them according to the revised requirements from [LIVE D9.4]. A detailed matching between requirements and tasks from the workflows is presented. Furthermore, a detailed workflow for the preparation phase and a less detailed workflow for the post-processing phase have been added. Finally, chapter 3 provides a short subsumption of necessary changes to the architecture coming from the workflows. After a very short retrospection on the architecture of the first prototype, chapter 4 presents the new system architecture based on the revised workflows. This is accomplished by providing a component-based view on the one hand and more detailed inspections on newly defined components and components which have been subject to major changes on the other. The first part intends to give an overview on the performed adaptations of the architecture for each component. The latter part is meant to serve as a guideline for the developers of the various components and tools on which interfaces will be needed between which components and which data has to be exchanged. Finally, chapter 5 provides a conclusion reflecting the changes to the architecture.

(1) Description of the overall implementation and integration plan (D8.1)

The document D8.1 is the first deliverable from work package 8 (Integration). While other technical work packages are about researching and developing innovative techniques for the application area, WP8 deals with the more mundane tasks of integrating those software pack-ages with each other and into an existing broadcast environment. So the work underlying this document consisted of the following tasks: isolate some attractive usage scenarios showing several of the components working in concert, coordinate the partners efforts on specifying interfaces between their respective components, study the existing target environment at the broadcasters premises and finally develop some missing glue necessary to make a first running prototype feasible as early as possible. The glue mentioned in the preceding paragraph consists of some additional “orphaned” components not included in some other work package, plus some common infrastructure (e.g. standard middleware) on which all components can be based. Both types of software packages are described in this document as well. The document describes the objectives of the prototype and summarises some of its features; the prototype's components and their internal and external interfaces, as well as how the sys-tem will be embedded into the broadcaster’s workflow and infrastructure are explained. Besides, a list of the envisaged implementation techniques and tools is given. The document ends with a presentation of the schedule for the necessary implementation steps.

(1) D7.2 Basic Specification of the Intelligent Media Framework

This report presents the basic specification of one of the core subsystems developed in the LIVE project: The “Intelligent Media Framework” provides a robust framework for the creation, management and delivery of so called “Intelligent Media Assets” under real-time conditions. The specification provided in this report is called “basic” in the sense, that it reflects the requirements of the first 18 months of the project duration and specifies the subsystem to serve the integration of the first prototype of the LIVE production support system. The basic specification will be further extended in the course of the project.

(1) First Prototype of the Intelligent Media Framework - D7.3 Documentation

This document is part of LIVE’s deliverable D7.3 “First Prototype of the Intelligent Media Framework” which is delivered in two parts: 1.Software: delivered on DVD/CD; 2.Documentation: this document. Part 2, the documentation, provides detailed information about the implementation of the Intelligent Media Framework for the 1st prototype as well as installation guidelines for the installation of the software delivered on DVD/CD as well as instructions on how to use the services of the Intelligent Media Framework. Not contained within this document are instructions on how to build the Intelligent Media Framework out of the TRAC-subversion system. Part 1 however is a packaged version of a tested IMF installation; all the described installation steps have been executed beforehand. The only required steps to run this particular installation are to extract the archive and the start the JBoss server by invoking the run.bat or run.sh file in the servers bin directory.

(1) D8.7 Evaluation of LIVE system integration in other broadcast environments

This document deals with the LIVE System integration in other broadcast environments. It provides an overview on the required facilities and necessary adaptations when bringing all or only some of the LIVE components into an existing broadcast environment. Especially the option to only select some of the usage scenarios supported by the LIVE System is stressed in the report. The report concentrates on the aspects of integration that are independent from a specific broadcast environment. The findings were made during the system integration for the Olympic field trial and will be outlined in chapter 3. Afterwards the usage scenarios supported by LIVE are summarized in chapter 4 as introduction to the following sections dealing with the related requirements and adaptations. Due to the only limited number of connections and dependencies, there are only few requirements for broadcast equipment as presented in chapter 5. A special focus was laid on the consumer system, since the need for adaptations is foreseen to be much higher than for the other fields. But as LIVE already proved by integrating with three different consumer systems the efforts are predictable and reasonable. Chapter 6 concentrates on the practical requirements entailed with a use case of the LIVE System. Here the personnel as well as the technical resources are described and the work spaces with their related work flow are presented. The document is finished with chapter 7 giving a summary on the necessary adaptations.

(0.7) Adding Lossless Video Compression to MPEGs

In this correspondence, we propose to add a lossless compression functionality into existing MPEGs by developing a new context tree to drive arithmetic coding for lossless video compression. In comparison with the existing work on context tree design, the proposed algorithm features in 1) prefix sequence matching to locate the statistics model at the internal node nearest to the stopping point, where successful match of context sequence is broken; 2) traversing the context tree along a fixed order of context structure with a maximum number of four motion compensated errors; and 3) context thresholding to quantize the higher end of error values into a single statistics cluster. As a result, the proposed algorithm is able to achieve competitive processing speed, low computational complexity and high compression performances, which bridges the gap between universal statistics modeling and practical compression techniques. Extensive experiments show that the proposed algorithm outperforms JPEG-LS by up to 24% and CALIC by up to 22%, yet the processing time ranges from less than 2 seconds per frame to 6 seconds per frame on a typical PC computing platform.

(0.7) Basic System Architecture (D9.2)

The goal of this deliverable is to provide a high-level overview of the idea of the LIVE project and its basic system architecture. The description goes to the level of detail that is needed to understand the basic architecture. For more detailed descriptions, particularly of the subsystems, the reader is referred to the respective subsystem deliverables. The described first basic system architecture of this document was developed including the results of the first six months of research within the LIVE project. Derived from the basic idea of a system - whereby an interactive digital broadcaster should be able to create a non-linear multi-stream video show in real-time, which changes due the consumers’ interests - first user tests were made and analysed at the public Austrian broadcaster ORF (Österreichischer Rundfunk). These tests resulted in a set of initial requirements (compare deliverable D9.1 “Results from the initial requirement analysis”). Based on these requirements, actors of the LIVE System and their basic use cases were identified. This finally results in the basic system architecture which is briefly described in this deliverable. For this deliverable a public synopsis (D9.3) is available too.
