The Public

In recent years, the number of forged videos circulating on the Internet has immensely increased. Software and services to create such forgeries have become more and more accessible to the public. In this regard, the risk of malicious use of forged videos has risen. This work proposes an approach based on the Ghost effect knwon from image forensics for detecting forgeries in videos that can replace faces in video sequences or change the mimic of a face. The experimental results show that the proposed approach is able to identify forgery in high-quality encoded video content.

Machine Processing

With the current Internet bandwidth capacities and machine processing performance the personal computer has become an affordable and flexible multimedia platform for high quality audio and video content. Besides the delivery of services such as TV, telephone and radio, the Internet can also be used for the instantaneous bidirectional exchange of musical information. Due to the variety and complexity of already existing remote music and communication approaches, an elaboration on this topic is mandatory, which covers any relevant musical, technical or interdisciplinary aspect of remote musical interaction. Therefore, this chapter gives an overview of currently applied technologies and possibilities with their theoretical background.

AbstractObjectiveThis study evaluated the quality of YouTube content focusing on common paediatric otolaryngology procedures, as this content can influence the opinions and medical decisions of patients.MethodsA total of 120 YouTube videos were compiled to review using the terms ‘adenoid removal’, ‘adenoidectomy’, ‘ear tubes’, ‘tympanostomy’, ‘tonsil removal’ and ‘tonsillectomy’. The Discern criteria was used to rate the quality of health information presented in each video.ResultsThe mean bias Discern score was 3.18 and the mean overall Discern score was 2.39. Videos including US board certified physicians were rated significantly higher (p < 0.001) than videos without (bias Discern score = 3.00 vs 2.38; overall Discern score = 3.79 vs 1.55). The videos had been viewed a total of 176 769 549 times.ConclusionUnbiased, high quality videos on YouTube are lacking. As patients may rely on this information when making medical decisions, it is important that practitioners continually evaluate and improve this video content. Otolaryngologists should be prepared to discuss YouTube content with patients.
