Efficient validation/verification of a robust DVB-H link layer

Abstract

Abstract-Currently, various semiconductor manufacturers develop silicon solutions for DVB-H receivers. One of the key functions in a DVB-H receiver is the link layer. In order to differentiate, manufacturers can choose between basic or advanced link-layer implementation concepts, resulting in modest or excellent performance. This paper presents the required validation and verification tools for evaluating the DVB-H link-layer robustness, capable of generating and analyzing extreme signal conditions. Furthermore, we also discuss an advanced analysis tool required to inspect the output IP-based data, Service Information and Program Specific Information of the link layer. The earlier simulation results for improved link-layer performance presented by the tools are validated from a newly developed silicon implementation.

DVB-H Link Layer

“…Besides power reduction, time-slicing has also the advantage that the front-end can be reused during the off-times for peeking into neighboring cells to perform service discovery and enabling seamless horizontal handover for a specific service [37]. 6 Time-slicing information is carried by the real time parameters, which are available in each of MPE and MPE-FEC sections. The off-period starts after the end of a service burst.…”

“…This section presents the DVB-H generator and analyzer concept required for validation and verification of a robust DVB-H link layer, as depicted in Fig. 8.13, capable of generating and analyzing extreme signal conditions [6]. The generator and analyzer system aspects are based on the link-layer architecture to be validated.…”
