Robust playback of digital video streams in wirelessly connected applications

Wirelessly connected devices continue to offer new features and experiences, and immersive TV is emerging as the next big thing. These media streaming applications have been enabled by the rapid development of video and communication technologies, and in the near future other media streaming applications such as wirelessly connected DVD players, IPTV, and distance learning (tele-education) will emerge.

Broadcast signals can be error prone, especially when the recipient is on the move.
Moreover, data loss and reduction in signal strength occur frequently during transmission due to a process known as multipath transmission fading. Without adequate signal processing at the receiving end the video quality is degraded.

Scientists at Philips are developing innovative digital signal processing (DSP) solutions and Intellectual Propriety (IP) cores that compensate for the variable quality of network transmission, resulting in a high-quality digital video under all circumstances. The DSP solution and IP cores for the enhancement of the quality of immersive TV consists of dedicated algorithms and IC hardware, and will make immersive TV a great visual experience.
