To address the network firewall issue, we developed a complete novel solution via HTTP Live Streaming (HLS) protocol and FFMPEG that is a powerful cross-platform command line video transcode/encoding software package on the server side. In this paper, a novel, real-time video streaming transmission approach based on HLS for the remote laboratory development is presented. With this new solution, the terminal users can view the real-time experiment live video streaming on any portable device without any firewall issues or the need for a third party plug-in. -

VIDEO STREAMING SERVICE Video Streaming Service (HLS & Nginx)
VIDEO STREAMING SERVICE Video Streaming Service (HLS & Nginx) 1. Introduction This document describes a proof of concept undertaken by PalC Networks for developing a video streaming application. 1.1. Introduction to Video Streaming service Streaming Media may be defined as listening or viewing media in real time as it comes across the World Wide Web. With streaming technology, users can watch and listen to media while it is being sent to their browser, instead of waiting for it to completely download and then playing it. Before streaming technology was available, a user might wait an hour (or more!) to completely download a short media file. In general, media files are huge. For example, five minutes of uncompressed video would require almost one gigabyte of space! So, when the audio and video is prepared for streaming, the media file is compressed to make the file size smaller. When a user requests the file, the compressed file is sent from the video server in a steady stream and is decompressed by a steaming media player on the user's computer to play automatically in real time. A user can jump to any location in the video or audio presentation. Streaming media generally tries keep pace with the user's connection speed in order to reduce interruptions and stalling. Though general network congestion is unavoidable, the streaming server attempts to compensate by maintaining a constant connection. 2. HLS Streaming: HLS streaming (HTTP Live Streaming) has emerged as the standard in adaptive bitrate video. Adaptive bitrate video delivery is a combination of server and client software that detects a client’s bandwidth capacity and adjusts the quality of the video stream between multiple bitrates and/or resolutions. -

PAVOL KORCˇ EK SUPERVISOR BRNO 2011 Abstrakt S narastajúcim poètom vozidiel na na¹ich cestách sa èoraz väčšmi stretávame so súèasnými problémami dopravy, medzi ktoré by sme mohli zaradi» poèetnej¹ie havárie, zápchy a zvýše- nie vypú¹»aných emisií CO2, ktoré zneèis»ujú životné prostredie. Na to, aby sme boli schopní efektívne využíva» cestnú infra¹truktúru, nám môžu poslúžiť napríklad simulátory dopravy. Pomocou takýchto simulátorov môžme vyhodnoti» vývoj premávky za rôznych poèiatoè- ných podmienok a tým vedie», ako sa správa» a reagova» v rôznych situáciách dopravy. Táto práca sa zaoberá témou akcelerácia mikroskopickej simulácie dopravy za použitia OpenCL. Akcelerácia simulácie je dôležitá pri potrebe analyzova» veľkú sie» infra¹truktúry, kde nám bežné spôsoby implementácie simulátorov nestaèia. Pre tento úèel je možné použiť naprí- klad techniku GPGPU súèasných grafických kariet, ktoré sú schopné paralelne vykonáva» v¹eobecné výpoèty.
