Uncompressed video

Uncompressed video refers to video data that has not been compressed or reduced in size, resulting in large file sizes that require significant storage and transmission capabilities. Due to its size, handling uncompressed video data can be expensive and pose considerable challenges in terms of storage and communication.From: Image and Video Compression [2019], A New Low Complexity Bit-truncation Based Motion Estimation and Its Efficient VLSI Architecture [2021]

Uncompressed video is a data hog from a bandwidth and storage perspective. For example, top-end, raw digital cinema resolution is ~4 K × 2 K pixels, 24 FPS, yielding ~7 Gbps data rate. A standard definition 4:4:4 R’G’B’ signal has an active picture area bit rate of ~311 Mbps. It is no wonder that researchers are always looking for ways to reduce the bit rate yet maintain image quality. Methods #2, #3, and #4 in the preceding list are bit rate reduction methods and are broadly rated against image quality in Figure 11.15. To better understand Figure 11.15, we need to define the term lossy.

The vast amount of uncompressed video data poses considerable challenges in storage and transmission. The advancement of technologies related to storage and transmission of video content cannot completely meet the large volumes of video data generated. To cope with this challenge, video compression or video coding techniques have been developed by researchers from time to time. These algorithms typically increase the coding efficiency but also increase computational complexity.
