The bitstream structure of layered media formats such as scalable video coding (SVC) or multiview video coding (MVC) opens up new opportunities for their distribution in Mobile TV services. Features like graceful degradation or the support of the 3-D experience in a backwards-compatible way are enabled. The reason is that parts of the media stream are more(More)
Long Term Evolution (LTE) standard enhances Multimedia Broadcast Multicast Services (MBMS) to provide highly efficient transmission of multicast/broadcast services. This paper aims at clarifying which is the best option for the Enhanced MBMS (E-MBMS) network configuration according to the operator needs. Besides, it describes the main technical features of(More)
This paper reviews the main technical solutions adopted by the next-generation mobile broadcasting standard DVB-NGH, the handheld evolution of the second-generation digital terrestrial TV standard DVB-T2. The main new technical elements introduced with respect to DVB-T2 are: layered video coding with multiple physical layer pipes, time-frequency slicing,(More)
In this paper we investigate the potential gain that can be obtained in DVB-H using application layer forward error correction (AL-FEC) to perform a multi-burst protection of the transmission for improving the reception of streaming services for mobile terminals. Compared to the conventional approach with link layer multi protocol encapsulation FEC(More)
This paper provides a review of the second generation of terrestrial digital video broadcasting standard (DVB-T2). DVB-T2 is the evolution of DVB-T and, together with DVB-S2 and DVB-C2, inaugurated a new transition from the first-generation digital broadcasting systems, similar to the transition from analog-to-digital systems. In this paper, the most(More)
In this paper, power-based layer-division multiplexing (LDM) is studied as a means to provide unequal error protection in digital terrestrial television (DTT) systems by adopting an information-theoretic approach. LDM can potentially offer fundamental performance gains as compared to traditional time-division multiplexing (TDM) or frequency-division(More)
This article presents and analyzes the multicast transmission problem of file download services to several users simultaneously in 3G mobile networks with MBMS (multimedia broadcast multicast services). MBMS is the second major enhancement in the downlink of the 3G standard after HSDPA (high-speed downlink packet access). Whereas HSDPA supports high speed(More)
This article analyzes the challenges and opportunities that the upcoming definition of future 5G mobile networks brings to the mobile broadband and broadcast industries to form a single converged network. It reviews the state-of-the-art in mobile and broadcast technologies and the current trends for convergence between both industries. This article(More)
Mobile TV services are expected to become a key application in future wireless networks. The recently proposed terrestrial digital broadcast technology, DVB-H, especially designed for mobile services, is regarded as a powerful alternative to the 3G cellular networks that already offer these services out on a point-to-point basis. Unfortunately, the cost of(More)
With the spectrum liberation obtained by the deployment of digital terrestrial television and the analog TV switch-off, new bands are being assigned to IMT LTE. In the first cellular deployments in the digital dividend at the 800 MHz band, problems emerged due to the interference cellular networks can cause to DTT signals. Possible solutions imply either an(More)
