5 Adaptive Multimedia Content Delivery over Wired and Wireless Networks Performance Engineering Laboratory School of Electronic Engineering Dublin City University, Ireland
6 Overview Streaming multimedia content Trends Delivery infrastructure Challenges 1) Quality-Oriented Adaptive Scheme (QOAS) 2) Prioritised Adaptive Multimedia Content Delivery Scheme (PAM) 3) Battery Power Adaptive Wireless Multimedia Streaming (BAM) Conclusions
7 Multimedia Streaming - Trends Current Status High popularity of streamed multimedia-based services e.g. digital TV, Video on Demand, videoconferencing Definite trend from analogue broadcast to on demand digital content delivery Wireless technologies enable multimedia delivery anywhere with low cost Mobile devices are becoming increasingly popular
8 1) Multimedia Streaming Evolution - Step One Approach Centralised multimedia server Distributed multimedia users Direct streaming across Internet or IP network Server Clients Internet / IP Network Multimedia Database
9 Quality-Oriented Multimedia Streaming Issues Network operators and service providers want more customers simultaneously served and high infrastructure utilization to maximise their benefit This reduces average bitrate per customer and increases loss => decrease in quality Viewers have high quality expectations This requires multimedia streaming with high bitrate and low loss => decrease in utilization (and income) Solutions Adaptive streaming Adjusts multimedia content (bitrate) to fit available bandwidth
10 Multimedia Streaming Architecture Control QOAS Server IP Network Data Control Data Control Data o r Control QOAS Clients Data Control Multimedia Data Database
11 Quality-Oriented Adaptive Scheme (QOAS) QOAS = application-level multimedia streaming solution QOAS dynamically optimises: high infrastructure utilization and more customers as desired by network operators and service providers high user perceived quality as preferred by the viewers QOAS employs a client-server feedback scheme*: Client monitors QoS and QoE parameters Client regularly informs server in terms of overall grades Server performs bitrate adaptations to increase user perceived quality Note Users prefer controlled reduction in multimedia quality to random losses * IEEE Transactions on Broadcasting, vol. 52, no. 2, June 2006, pp
12 QOAS Principle Illustration QOAS Server QOAS Client Server Arbitration Scheme (SAS) Feedback Quality of Delivery Grading Scheme (QoDGS) Short Term Long Term Highest Same Content Different Quality Streams Checkpoint 1 Checkpoint 2 Transmission & Perceived Quality Parameters Above medium Medium Below medium Lowest Data Adapted Stream
13 QOAS Testing - Summary Objective Tests A simulation model, written in C++ and OTCL, was built and tested using Network Simulator 2 Simulations tested QOAS performance with various multimedia content in different delivery conditions The results were very good stand-alone alone and in comparison with two other solutions end-user perceived quality, loss rate, link utilization and number of customers simultaneously served Subjective Tests The prototype system was built using Microsoft Visual C End-user perceived quality was assessed with human subjects while streaming various clips in different delivery conditions The results showed very good perceived quality and confirmed the simulation results
14 QOAS Testing - Selected Results * IEEE Transactions on Broadcasting, vol. 53, no. 1, part 1, March 2007, pp
15 2) Multimedia Streaming Evolution - Step Two Approach Centralised multimedia server and IP network Distributed multimedia users Distributed local IP network (wireless) Server WLAN 1 Clients Internet / IP Network Multimedia Database WLAN 2
16 High Quality Multimedia Streaming Issues Large diversity of devices They have different requirements (average bitrate, display size, power) Wireless network solutions Lower delivery rates Affected by collisions, signal attenuation with distance and interference User subjective assessment Solutions Users have different expectations in relation to application, device, etc. Differentiated adaptive streaming Prioritised adjustment of multimedia content (bitrate)
17 Wireless Distribution of Multimedia Services - Architecture Idea: Alarm Distribution of multimedia-based services Single wireless multimedia gateway (server+wireless access point) Multiple wireless-enabled heterogeneous devices (clients)
18 Prioritised Adaptive Multimedia Content Delivery Scheme (PAM) Principle*: Maintains high end-user perceived quality in spite of variations in the characteristics of the wireless network Enables an increased number of streams to be served anytime, anywhere, and to various devices E.g. desktops, laptops, PDAs, smart phones, wide screen TVs, game consoles, etc. Allows differentiated treatment per view-point based on priorities assigned either by users, based on their subjective assessment or automatically detected from the device characteristics (e.g. living room home theatre has higher priority than game consoles) * IEEE International Conference on Telecommunications, Funchal,, Portugal, May 2006
19 PAM Principle Illustration Server quality state Different quality multimedia streams Client priority Adapted stream Highest High Above medium Medium Below medium Normal Lowest Low Wireless IP Network Priority High Client Intelligent Media Server Priority Normal Client Multimedia Database Priority Low Client
20 PAM Testing Setup Network Simulator 2 + wireless extension Dumbbell topology (N senders, 1 bottleneck link, N receivers) Comparison between non-adaptive, equal-priority and PAM streaming Assessment in terms of user perceived quality On ITU-T P.910 subjective 1-5 scale: 5 - excellent ; 1 - bad S1 Sender Instances C1 DiffQoS Multimedia Clients S2 B1 B2 C2 SN DiffQoS In- Home Access Point Server CN Wireless Local Area Network
21 PAM Testing - Selected Results Results 5 Average Quality (1-5) NoAd edif f QoS pdif f QoS 0 Normal/ Normal Normal/ Low Normal/ Normal Normal/ High Client 1 Client 2 Client 3 Client 4
22 3) Multimedia Streaming Evolution - Step Three Approach Local multimedia server Distributed battery-powered devices Wireless local IP network Server Client WLAN Multimedia Database
23 Multimedia Streaming to Battery-powered Devices Issues Large diversity of devices They have different specs, including battery characteristics Wireless data delivery High power consumption Dependent on solution User preference Solutions Users prefer to have their tasks completed Battery-power-aware adaptive streaming Client device power-based adjustment of multimedia content (bitrate)
24 Multimedia Streaming to Battery-powered Devices - Architecture Idea: Distribution of multimedia-based services Wireless multimedia gateway (server + wireless access point) Battery-powered wireless-enabled devices (clients)
25 Battery Power Aware Adaptive Wireless Multimedia Streaming (BAM) Principle*: Applies incremental power saving solutions in all multimedia streaming stages Maintain acceptable user perceived quality Reception modify the process of wireless packet transmission in order to allow the device to sleep for longer Decoding Adapt multimedia bitrate to adjust power required for decoding Playing Adjust volume and brightness levels * IEEE International Conference on Communications, Glasgow, UK,
26 BAM Principle Illustration
27 BAM Testing Summary Real-life BAM implementation in the reception stage only Adaptive Buffer Power Save Scheme (AB-PSM) Comparison between no-power save, IEEE legacy PSM and two versions of AB-PSM Multimedia content is continuously streamed from a server to a PDA via an WLAN until device battery depleted Assessment in terms of total playout time Increase ~ 230% in comparison with the no-psm Increase ~ 50% in comparison with legacy PSM End-user perceived quality was not affected
