 Obiettivo del progetto (Objective)

'At the dawn of the new millennium, we have witnessed a proliferation of mobile devices whose functionality goes well beyond their initial use as telephones. Nowadays, apart from mobile phones, we have in our disposal geographic positioning devices, personal organisers, email and text communication assistants, music players which can store thousands of songs, and video players with medium-definition capabilities. It is becoming increasingly apparent that mobile devices should achieve a greater level of integration regarding the services they offer. The goal is that soon it will be possible to own a single inexpensive high-quality mobile gizmo, which can be used as a tele- and video- phone, email client, MP3 player, document and spreadsheet processor, GPS locator, and so forth. In addition, most mobile devices now include some sort of navigation capability, either through the integration of a standard GPS module, or through the clever use of the cellular network topology and signal strength. In this project, our focus is on the enhancement of high-quality video, sound, and television delivery capabilities of mobile devices that will enable them to provide interactive and immersive media applications. We will address limitations to current audio and video coding methods which restrict the use of mobile devices to offering only a low-quality streaming media presentation to the user. In order to overcome these limitations, novel algorithms which go well beyond the currently developed techniques and concepts are needed. An important aspect of this project is the conscious exploitation of the location awareness that these new devices offer, for dynamically adapting the delivery of multimedia content. The proposed consortium consists of partners with complementary expertise which covers all the involved research areas, from the point of capturing the media content to the point that it is dynamically presented through a location aware mobile device to the user.'

Introduzione (Teaser)

Technologies for providing rich multimedia content significantly improve the quality of everyday life. EU-funded scientists worked on ways to help end users of portable devices enjoy multimedia services with enhanced service experience.

Descrizione progetto (Article)

Mobile devices are generally limited in resources: memory, network bandwidth and, in particular, processing power. Other obstacles such as limited graphic capabilities and audio rendering are also narrowing the choice of audiovisual applications.

Improving delivery of multimedia content to these devices was the aim of the EU-funded project 'Efficient location-aware audio-visual delivery of high-quality content to mobile devices' (http://www.avid-mode.eu/ (AVID-MODE)).

Rigorous project research achieved significant progress in audio and video signal processing, including hardware and middleware issues for mobile devices. As such, a novel audio coding scheme enabled scientists to deliver immersive audio experience and robust sound capturing. A remote listening device helped analyse acoustic echo cancellation and noise reduction to better capture audio in a noisy environment. Furthermore, scientists made significant enhancements in room and car equalisation for optimal audio playback experience.

Through the mobile device GPS, AVID-MODE improved location-aware audio services to ultimately provide customised multimedia content presented in an interactive way. Other improvements include interference cancellation in devices that combine different standards such as GPS, GSM, DVB-T/H or Wi-Fi. Work was also geared towards optimising the H.264 baseline decoder and testing the new one, H.265.

AVID-MODE designed a unified platform for digital TV and multimedia playback that operates on different media platforms, including mobile devices. In addition, it improved remote control communication of these devices.

Another project achievement was the design of a novel hand-gesture recognition method, thus optimising the performance of limited-complexity devices. Integration of all control and display capabilities of modern boats on portable devices concluded project tasks.

Project outcomes are meeting the ever-increased need for achieving a greater level of integration regarding mobile device services. High-quality video, sound and TV improve the user experience, while users can also interact with the multimedia content.
