Project MITSU

Abstract

The objective of MITSU (next generation MultImedia efficienT, Scalable and robUst Delivery) is to study and develop the next generation of multimedia streaming systems to be used over wireless networks. Market opportunities and pressure are pushing toward a very fast deployment of video solutions that are not interoperable together and that imply an increasing processing complexity. Video systems are entering into a new age where contents will have to be delivered to the user whatever the device or network he/she is using (i.e. with the network he/she is also currently connected to). While considering state of the art technologies in that field, MITSU intends to study and implement this video interoperability while minimising complexity and power consumption.

Heterogeneous wireless environment, increases requests for retransmissions increasing bandwidth and energy and also creating inherent congestion on the network. New video consumption mode relying upon the use of smartphones and tablets have introduced new protocols (HTTP streaming), not interoperable between them and increasing the issue of data retransmission. New video codecs are also under development, providing more compression efficiency with increased complexity or targeting low complexity.

MITSU will handle all of these evolution to propose robust, efficient and interoperable video streaming solution by studying and implementing the following key elements:

• MPEG HEVC video codec and its competitors

• Video streaming protocols and format interoperability

• Video transcoding and transrating

• Video quality metrics and probes

• Robustness enhancement

• Context aware video streaming adaptation

• Management of heterogeneous networks Cross-layer optimisation

• Privacy, security and content protection

• Latest generation of mobile phone communication system (4G) Multimedia and security application use cases implementation

• Field trials
