PCoIP

PCoIP protocol

PCoIP is a UDP-based protocol that is host rendered, multi-codec and dynamically adaptive. Images rendered on the server are captured as pixels, compressed and encoded and then sent to the client for decryption and decompression. Depending on the image, different codecs are used to encode the pixels sent since techniques to compress video images differ in effectiveness compared to those for text. The protocol also dynamically adapts its encoding based on the available bandwidth. In low-bandwidth environments it uses lossy compression where a highly compressed image is quickly delivered, followed by additional data to refine that image, a process termed "build to perceptually lossless". The default is to use lossless compression which is used when there is minimal network congestion or when explicitly configured, as might be required for scenarios where image fidelity is more important than conserving bandwidth, e.g. for medical imaging.
