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.

  • Keyframe Insertion: Enabling Low-Latency Random Access and Packet Loss Repair February 11, 2021Keyframe Insertion: Enabling Low-Latency Random Access and Packet Loss Repair
    From a video coding perspective, there are two challenges when performing live video distribution over error-prone networks, such as wireless networks, namely random access and packet loss repair. There is a scarceness of solutions that do not impact steady state usage and users with reliable connections. The proposed solution minimizes this impact by complementing a ...
