Abstract:
Traditionally, consumer electronics devices do not have an optimized and flexible infrastructure to provide multimedia services, the latter being local or remote. Furthermore, support for new formats and elements also presents some complexity, which reaches its peak when more sophisticated arrangements, such as those involving specific elements of the digital TV (DTV) environment (e.g., tuner, demultiplexer, decryption module, and decoder), are required. In addition, different multimedia processing topologies are realized with distinct software modules, which must work in harmony and are responsible for recording, editing, flow control, and playback. Consequently, a methodology capable of ensuring quality and robustness regarding such implementations is paramount. In this paper, we present an automated testing architecture that provides conformance and robustness test scenarios for multimedia processing infrastructures employed in DTV receivers. Experiments with a real implementation of it, focused on DTV receivers conforming to the Brazilian standards, showed its effectiveness, revealing both robustness and conformance issues in a mature and already tested multimedia stack. Moreover, regarding a comparison carried out in the context of robustness testing, its test generation engine, based on fuzzing, created a very uncommon scenario that was not tackled by a popular tool.
