Flexible Macroblock Ordering for Context-Aware Ultrasound Video Transmission over Mobile WiMAX

[摘要] The most recent network technologies are enablinga variety of new applications, thanks to the provision of increased bandwidth and better management of Quality of Service. Nevertheless, telemedical services involving multimedia data are still lagging behind, due to the concern of the end users, that is,clinicians and also patients, about the low quality provided. Indeed, emerging network technologies should be appropriatelyexploited by designing the transmission strategy focusing on quality provision for end users. Stemming from this principle, wepropose here a context-aware transmission strategy for medical video transmission over WiMAX systems. Context, in terms ofregions of interest (ROI) in a specific session, is taken into account for the identification of multiple regions of interest,and compression/transmission strategies are tailored to such context information. We present a methodology based on H.264medical video compression and Flexible Macroblock Ordering (FMO) for ROI identification. Two different unequal errorprotection methodologies, providing higher protection to the most diagnostically relevant data, are presented.
