“…In Reference [23], practical aspects for the integration of such a scheme into the DVB-H framework have been studied, combining PB with Raptor Codes [24], which are the most efficient erasure fountain codes known. Moreover, in Reference [25] the scheme has been enhanced even more by incorporating scalable video and multiple sites reception.…”

SUMMARYMobile TV started almost 30 years ago as a research project, but only just recently TV-like services for mobile users on handheld devices have become reality. In this work, we want to give an overview of both the history and current advances in this highly active field of research, including unicast and broadcast media streaming over wireless channels and efficient forward error correction (FEC) mechanisms at the application layer.

“…While techniques have been proposed to deliver VoD-like services over broadcast networks using intelligent buffering and scheduling of access to the broadcast medium e.g. [8], the architecture of broadcast systems is generally inappropriate for real-time interactive delivery of arbitrary video on demand. For these reasons, alternative solutions, based on bidirectional interactive technologies must be considered.…”

A simulation study of delivery of streaming video on-demand via IEEE 802.16 based technologies is described. A number of scenarios are simulated which are representative of rural area deployments of such technologies. The study finds that IEEE 802.16 can support up to 9/10 simultaneous users streaming typical cinematic video content in CIF resolution, 24 frames/s, at average rates of around 750 kbps. Further, the study demonstrates the utility of H.264/AVC Scalable Video Coding (SVC) and a buffer-based congestion control algorithm in an adaptive video streaming solution.

“…Related to this research, there have also been studies dealing with nVoD and error protection. The work described in [21] and [22] is based on harmonic nVoD schemes. This approach splits content into segments of equal size, internally divides segments into chunks, and applies linear coding at different rates.…”

“…As a result, protection is equal for all segments at the cost of adding an initial playback delay that rises exponentially with protection level. At this point, it is important to stress that protection levels for the schemes in [21] and [22] remain constant during the entire playback, while the IEC scheme, due to its architecture, increases it every time a new slot is downloaded; i.e. over time.…”

An Efficient NVoD Scheme Using Implicit Error Correction and Subchannels for Wireless Networks

Implicit Error Correction (IEC) is a near Video-on-Demand (nVoD) scheme that trades bandwidth utilization for initial playback delay to potentially support an infinite number of users. Additionally, it provides error protection without any further bandwidth increase by exploiting the implicit redundancy of nVoD protocols, using linear combinations of the segments transmitted in a given time slot. However, IEC packet loss protection is weaker at the beginning of the playback due to the lack of implicit redundancy and lower decoding efficiency, resulting in worse subjective playback quality. In tackling this issue, this paper contributes with an extension of the original nVoD architecture, enhancing its performance by adding a new element namely, subchannels. These subdivisions of the original channels do not provide further packet loss protection but significantly improve the decoding efficiency, which in turn increases playback quality, especially at the beginning. Even for very high packet loss probabilities, subchannels are designed to obtain higher decoding efficiency which results in greater packet loss protection than that provided by IEC. The proposed scheme is especially useful in wireless cooperative networks using techniques such as network coding, as content transmissions can be split into different subchannels in order to maximize network efficiency.
