Multimedia streaming is one of the most popular services today. When user in a mobile scenario, delivery multimedia becomes more challenging. Mobile suffers from discontinuous playback that sometimes impairs experience. Among other factors, this also due to high network bandwidth variation can experience along path. In some cases, available close zero when traversing tunnels or areas where capacity goes below what required for session be pause-less. Typically, media adaptation and rate...

The paper discusses methods for robust audio-video broadcast over the digital video broadcasting-handheld (DVB-H) system. DVB-H includes a link-layer forward error correction (FEC) scheme known as multiprotocol encapsulation (MPE) FEC, which provides equal protection (EEP) to transmitted media streams. Several approaches unequal (UEP) have been proposed in literature, and applicability of some them is analyzed paper. A UEP method based on priority segmentation streams chosen more detailed...

This paper provides an analysis on the optimal channel changing delay in DVB-H (Digital Video Broadcasting for Handhelds) channels Mobile Television. uses a time-sliced transmission scheme to reduce power consumption used radio reception receivers. Channel delay, i.e. from one audio-visual service another, is increased due time slicing DVB-H. One of significant factors Decoder Refresh Delay. The Delay start video decoding correct output decoder. minimized when time-slice starts with random...

Virtual reality (VR) provides unprecedented immersive experience using high-resolution spherical stereoscopic panoramic video. Such an is achieved by head-mounted display (HMD) which has very strict latency bounds in order to respond promptly user movements. Conventional streaming of VR video requires large bandwidth because the entire captured panorama transmitted. However, only a limited field-of-view (FOV) displayed HMD, resulting wastage bandwidth. To alleviate problem, this paper...

DVB-T2 has been recently standardized by the DVB organization. In this paper deployment of H.264/SVC in is discussed. We focus on system configuration aspects which provide optimal use features from point view. also propose modifications to error protection mechanisms that would consequently lead an improvement user experience. The data dependencies are exploited protect media unevenly according their priorities.

Mobile broadcast services have experienced a strong boost in recent years through the standardization of several mobile systems such as DVB-H, ATSC-M/H, DMB-T/H, and CMMB. However, steady need for higher quality is projected to surpass capabilities existing systems. Consequently, work on new generations technology starting under umbrella different industry consortia, DVB. In this paper, we address question how DVB-T2 transmission can be optimized improved reception. We investigate...

The Moving Picture Experts Group (MPEG) recently has developed a standard for compressing volumetric content known as video-based point cloud compression (V-PCC). V-PCC is multi-layer approach in which the information mapped onto multiple image layers. second layer considered including points that were not projected into first layer. Even though this dual-layer scheme provides better coding efficiency and reconstruction quality compared to single-layer approach, but it be very complex due...

Tune-in delay is the time elapsed from instant a program chosen, until rendering of chosen begins. This paper provides an analysis various components that affect tune-in and discusses methods to reduce this delay, in Digital Video Broadcasting - Handheld (DVB-H) systems.

Zapping-delay is an important factor contributing to the quality-of-experience (QoE) of any multimedia service; longer zapping-delay, worse QoE. Therefore, for a good QoE, it necessary bind zapping-delay within acceptable bounds. Coded video uses motion compensated prediction structure that contributes zapping-delay. In DVB-H, further increased because time-sliced burst transmission architecture. Hence, attempt must consider both coded video, as well architecture DVB-H. This paper analyzes...
