What is PCC?

PCC can refer to several technologies, making it important to understand the context. Here are a few common possibilities: * **Perceptual Compression Coding (PCC):** This is an advanced compression technology primarily used for 3D point cloud data. It aims to significantly reduce the size of 3D models while preserving the perceptual quality. It's used in applications like augmented reality, virtual reality, autonomous driving, and cultural heritage preservation. * **Performance-oriented Congestion Control (PCC):** This is a congestion control algorithm for network communication. Instead of relying on packet loss or delay as indicators of congestion (like TCP Reno), PCC actively probes the network to directly measure the relationship between sending rate and network performance (e.g., throughput and delay). Based on these measurements, it optimizes the sending rate to maximize performance. It is used to achieve better network performance, especially in scenarios with high bandwidth and variable network conditions. There are various implementations like PCC Vivace and PCC-Allegro. * **Programmable Communication Controller (PCC):** Less common these days, but can refer to a specialized hardware component used in communication systems. Because there is not enough information to determine which PCC you're asking about, this is a generalized overview.
