In particular, such services become more important when referring to the tele-medical applications through terrestrial Digital Video Broadcasting (DVB). Objective: One of the most significant aspects of video broadcasting is the quality and information content of data. Towards that end, several algorithms have been proposed for image processing in order to achieve the most convenient data compression. Methods: Given that medical video and data are highly demanding in terms of resources it is imper- ative to find methods and algorithms that will facilitate medical data transmission with ordinary in- frastructure such as DVB. Results: In the present work we have utilized a quantization algorithm for data compression and we have attempted to transform video signal in such a way that would transmit information and data with a minimum loss in quality and succeed a near maximum End-user approval. Conclusions: Such approaches are proven to be of great significance in emergency handling situa- tions, which also include health care and emergency care applications A R T I C L E H I S T O R Y Received: September 14, 2019 Revised: March 01, 2020 Accepted: March 18, 2020 DOI: 10.2174/2666255813999200821145606 Keywords: Quantization, healthcare telematics, digital video broadcasting, wireless communications, communications, internet. 1. INTRODUCTION At present, multimedia communications and broadcasting services are, still very much related to the type of broadcast network on which they are running. However, more and more services are being offered to the users that can be ac- cessed through various networks while many services re- quire the combination of different access networks. End us- ers meet content service providers, and vice versa, much more flexibly independent of time and location if they can use a standard network infrastructure. Nowadays, the actual trend is the convergence of net- working infrastructures and the integration of wireline and wireless, landline and mobile broadcasting technologies. This in turn creates a new operating environment, which will enable residential and mobile End users to access a wide *Address correspondence to this author at the National Technical University of Athens, Biomedical Engineering Laboratory, Herron Polytechneiou 9, 15780, Athens, Greece; Tel: 00302107467427; E-mail: dkoutsou@biomed.ntua.gr range of services any time any place. The challenge is to deliver to End users a multi-services operating environment (TV programs, Internet access, multimedia applications, etc.) through wireless infrastructures, specifically over existing terrestrial digital television networks. This new, multi-services approach led service providers to design, develop and finally deploy evolutionary tools, systems and platforms ready to handle various types of mul- timedia services utilizing network resources in the most effi- cient manner. Merging TV, Internet and multimedia broadcasting over a common platform (DTV) imposes the need for assigning resources with consideration to the requested quality of ser- vice (QoS). The systems deployed must be capable of allo- cating resources to certain services based on user demands, while maintaining the highest possible level of quality in the parallel broadcasting of the television programs. Bi-directional simultaneous exchange of voice, video and medical data through a single DVB-T stream through a common platform is of crucial importance for Public Safety and Disaster Relief (PPDR) emergency medical services. 2666-2566/21 $65.00+.00 © 2021 Bentham Science Publishers Send Orders for Reprints to reprints@benthamscience.net Recent Advances in Computer Science and Communications, 2021, 14, 3003-3011 3003 RESEARCH ARTICLE Quantization Algorithms in Healthcare Information Telematics Using Wireless Interactive Services of Digital Video Broadcasting
