Multimedia services over mobile networks pose several challenges, such as the efficient management of radio resources or the latency induced by network delays and buffering requirements on the multimedia players. In Long Term Evolution (LTE) networks, the definition of multimedia broadcast services over a common radio channel addresses the shortage of radio resources but introduces the problem of network error recovery. In order to address network errors on LTE multimedia broadcast services, the current standards propose the combined use of forward error correction and unicast recovery techniques at the application level. This paper shows how to efficiently synchronize the broadcasting server and the multimedia players and how to reduce service latency by limiting the multimedia player buffer length. This is accomplished by analyzing the relation between the different parameters of the LTE multimedia broadcast service, the multimedia player buffer length, and service interruptions. A case study is simulated to confirm how the quality of the multimedia service is improved by applying our proposals.
Multimedia services over mobile networks are becoming increasingly popular, but they come with their fair share of challenges. One of the main challenges is the efficient management of radio resources, as well as the inevitable latency induced by network delays and buffering requirements on multimedia players.
Long Term Evolution (LTE) networks have been developed to address the shortage of radio resources by enabling multimedia broadcast services over a common radio channel. However, this introduces a new problem: network error recovery. When errors occur in the network, it can cause disruptions in the multimedia service.
Standard protocols for LTE networks propose a combination of forward error correction and unicast recovery techniques at the application level to address these network errors. However, these techniques alone may not be sufficient to ensure smooth and uninterrupted multimedia playback.
This paper focuses on addressing the challenges of network errors in LTE multimedia broadcast services. It explores how to efficiently synchronize the broadcasting server and multimedia players, as well as how to reduce service latency by limiting the buffer length of multimedia players.
The research delves into analyzing the relationship between different parameters of the LTE multimedia broadcast service, buffer length of multimedia players, and service interruptions. By understanding these relationships, the authors propose strategies to improve the quality of the multimedia service.
This research is crucial in the field of multimedia information systems as it tackles the complex issue of network errors in mobile networks. The multi-disciplinary nature of this research is evident as it combines concepts from wireless communication (LTE networks), multimedia systems (broadcast services), and error recovery techniques.
Furthermore, this study’s findings have significant implications for various technologies such as Animations, Artificial Reality, Augmented Reality, and Virtual Realities. These technologies heavily rely on smooth and uninterrupted multimedia playback. By addressing network errors and reducing service interruptions, this research contributes to an improved user experience in these technologies.
In conclusion, this paper provides valuable insights into the challenges of network errors in multimedia services over mobile networks. Its findings can be applied to enhance the performance of LTE multimedia broadcast services and have implications for various multimedia technologies. This research bridges the gap between wireless communication, multimedia systems, and real-world applications, making it a noteworthy contribution to the field.
