Media Delivery

delivery networks

 

At IDLab-MEDIA, we are experts in delivery of video data. We deliver these media under constraints such as limited bandwidth capacity, low-latency requirements, and the available processing power at servers, edge nodes, and clients. We mainly focus on the compression aspects related to media delivery, and have expertise in:

  • Simultaneous encoding of multiple video streams: one video encoder creates multiple representations without increasing linearly in processing power requirements;
  • Scalable video encoding: with the power of scalable video, a single stream lets users display different qualities depending on their available bandwidth;
  • Fast video transcoding: one video format or quality is adapted to a different video format or quality;
  • Network-distributed video coding: the main bulk of video compression is performed in powerful servers, whereas other devices in the network, even in the edge nodes, can further adapt de video at a very low complexity, providing users with truly personalized bitstream and enabling low-delay applications such as 360-degree and panoramic interactive video streaming.

Often, a composition of these sources is sent to other devices in a single video stream. To minimize the computational complexity of this composition process, ...
  • Funding granted for imec.icon project HELP Video! (HW platforms for Embedded, Efficient, Low-latency, and Portable Video Processing) October 1, 2016 Funding granted for imec.icon project HELP Video! (HW platforms for Embedded, Efficient, Low-latency, and Portable Video Processing)For many multimedia systems development companies, video processing algorithms are an essential component to remain ahead of competition. However, development of this video processing IP is typically not done in-house, which is something that restricts them from maintaining full control of their product development. Algorithmic complexity and considerable implementation effort are an important hurdle for ...
