Enhancing effectiveness and reducing time of system validation for Interactive Multimedia LED TV

This work mainly focuses on automating validation of functionalities in complex LED TVs to overcome manual validation difficulties. Validation of the system which consists of functionalities of LED TV set is in the focus. An audio verification method was also developed and this is currently being deployed at TPVision (Previously Philips TV) for test automation of audio verification in Interactive Multimedia LED TVs. The method is computationally efficient, scalable and capable of quickly performing audio compare on audio captured through a LED TV in the presence of foreground voices and other dominant noise. It can verify any format of audio, be it .mp3, .mp4, .wav, AC-3 or Dolby Digital sound signals, etc. This task is performed using MATLAB and later built into standalone application, which is successfully integrated into existing test automation environment. This work helps to reduce the time required in validation and also to enhance audio validation efficiency and reduce time for the same in test automation process to come up with better working product.
