Converting audio signal to packet stream and propagating through wireless local area network (Wi-Fi technology) to loud speakers that may be located at different rooms will be a popular scenario of multimedia applications. Since the packets received by separate speakers varied with the transmission paths and environment to them, this made the playable contents different from one speaker to another...
The increased popularity of social media and mobile devices has radically changed the way people consume multimedia content online. As an example, users can experience the same event (e.g. a sports event or a concert) together using social media, even if they are not in the same physical location. Moreover, the introduction of the HTTP Adaptive Streaming principle has made it possible to deliver video...
Recently, the concept of adding multisensory media components to complement and extend user Quality of Experience (QoE) of traditional media has gained attention from both academia and industry. Research works stimulating additional senses like olfaction (sense of smell), haptic (sense of touch) and gustation (sense of taste) have emerged. In particular in theme parks, multisensory experiences that...
Recently, mobile broadcast services such as DMB, multimedia streaming services and IPTV, caused rapid increase of multimedia services sent over the Internet. It is important to define, measure and evaluate the elements related to the quality of providing the services over the Internet. In this paper, we propose multimedia quality measurement model that evaluates the quality of multimedia from consumers...
The previous work, suggests a portioned picturebroadcasting system where screens of small size are accumulated togenerate screen of bigger size through Ethernet network interfacethat helps in easy install & implementation of digitized displaydevices. The system makes use of Texas Instruments Da Vinciplatform, that is comprised of Da Vinci TMS320DM6646 dual coreCPU along an ARM9 core & C64+...
Many types of multimedia can be used to accommodate information for pervasive communication. Messages may be injected into them by information hiding techniques and extracted for various purposes. Such multimedia with messages embedded are called message-rich multimedia. A new method for creating message-rich videos is proposed in this study for people to exchange messages by display-and-imaging operations...
In the era of distributed computing, different components of distributed application need to be synchronized. For instance, two users watching a football match at geographically distinct location require synchronous multimedia display on their screens for synchronous shared experience. Inter-destination Synchronization (IDS) mechanism is a fundamental requirement for synchronous shared experience...
According to the Convergence of a vehicle and IT, In-Vehicle-Network (IVN) is complicated and the multimedia data is increased. Ethernet guarantees Quality of Service (Qos) of the existing Control Area Network (CAN) communication and has a high bandwidth. As a result, the Ethernet is recently developed a new standard. IEEE 802.1 Audio Video Bridging (AVB) supports to handle priority and queuing for...
Synchronizing multimedia data such as audio and video with the 3D depth skeletal data of a patient performing therapy at home is a challenging task. This is because the media characteristics of video, audio, and skeletal stream data are different. To keep the rich session information and therapeutic semantics, the multiple media streams need to be synchronized temporally in two tiers. At the end of...
The portion of video traffic in the total amount of Internet traffic has been increased. As the number of users and volume of content are increased, the content providers had been suffered for processing and transferring media and they have adopt CDN technology into their service so that their burden can be alleviated. The CDN technology can be classified into three different types; ‘server farm CDN’,...
We developed a robust approach that can be synchronized with accuracy to a media streaming group in a network congestion situation. This approach consists of a server-side and client-side algorithm. The server-side algorithm is used to transmit the playback information using a synchronization control packet to clients. The synchronization control packet is transmitted in an event-driven manner. The...
In this paper, a first approach for evaluating the Quality of Experience (QoE) for IoT (Internet of Things) applications is presented. Firstly, a layered IoT architecture is analysed to understand which QoE influence factors have to be considered in relevant application scenarios. Secondly, we introduce the concept of Multimedia IoT (MIoT) and define a layered QoE model aimed at evaluating and combining...
Modern-age technology enables us to consume multimedia for enjoyment and as a social experience. The traditional way to consume multimedia together (e.g., with family or friends in the living room) is being superseded by a location-independent scenario where geographically distributed users consume the same content while having a real-time communication channel among each other. Inter-Destination...
Synchronous, and real-time web-based collaboration on text and multimedia content is a hot research subject. Currently collaborative multimedia applications are loosely defined. It is current practice to consider any application that allows users to connect to each other in order to exchange information in writing or through video streams, in real-time, or near real-time, as a “collaborative application”...
The media presentation with temporal dependencies in the different media data, such as still image, text, video and audio is an open research area. This is an important issue for emerging distributed multimedia system. In this paper, we propose a new notion, called SRF (Synchronization Relation Flow) model that supports the multi-media synchronization in multi-screen service. The SRF considers of...
In this paper, we propose an effective design and implementation of a versatile embedded multimedia live streaming decoder system based on TI's DM814x processor, which can not only decode video live streams of various video codecs(H.264, MPEG-4, etc.), audio live streams of various audio codecs(AAC, MP3, G.711, etc.), but also demultiplex (demux) MPEG-2 TS, decode video stream and audio streams inside,...
Next-generation teleimmersive environments allow full-fledged collaboration of people in different geographical locations. The unique user experience poses new inter-sender synchronization requirement, which has not been investigated in past studies. The real-time nature of teleimmersive applications also introduce a tradeoff between synchronization quality and interactive quality during online synchronization...
This paper aims to present a transmission system model for a free-viewpoint television (FTV) service considering service scenarios. The proposed system model is based on the hy-bridcast of the digital terrestrial television broadcasting network and content delivery communication network. Also we propose the packet structure for the FTV transmission system considering the system requirement. The proposed...
Inter-Destination Multimedia Synchronization (IDMS) pushes social interactions to a new level. IDMS allows the users to experience multimedia together with friends, colleagues, or the family while having a real-time communication at the same time. The actual challenge of synchronizing the playout of each participant to a reference playout time is a tough task in terms of Quality of Experience (QoE)...
Automating multimedia quality checking is currently based on finding major audio/video artifacts. The “Monitoring Of Audio-Visual quality by key Indicators” (MOAVI) subgroup of the Video Quality Experts Group is an open collaborative project for developing No-Reference models for monitoring quality. MOAVI is a complementary, industry-driven alternative to Quality of Experience used to automatically...
