This paper sums up relevant topics covered by the special issue titled 'Real-Time Multimedia Coding and Transmission', including efficient content representation, multimedia transmission, hardware and software acceleration, and transcoding techniques. Introduction Applications such as online gaming, video conferencing, video surveillance systems, industrial visual inspection systems, and many other embedded image and video processing applications will require very fast image and video

Nowadays, full-high-definition video resolution is a reality in common smartphones, video cameras, and so on while multimedia market trends are focused on 4K ultra-high-definition resolution. In fact, several companies have recently presented their new devices which are able to visualize 4K video content like the new organic light-emitting diode Sony monitor or the Christie D4K3560 projector. These devices evidence the limitations of current real-time multimedia coding and transmission techniques due to the huge volume of information to be processed under real-time constraints. Furthermore, most of these applications run on devices with constrained resources (computational and/or power resources) like smartphones, tablets, laptops, embedded systems, and still/video cameras, thus making more challenging the design and deployment of new multimedia coding and transmission techniques.
