Table 1
Summary of main terminology and notations.
| | AVC | Advanced Video Coding | | Avg. video bitrate (bit/s) | Average (mean) of frame sizes of frames in a video sequence divided by frame period | | Number of bidirectional predicted (B) frames between successive I (or P) frames | | CoV | Coefficient of variation, that is, mean value of a random quantity divided by its standard deviation | | DCT | Discrete cosine transform | | Frame size (Byte) | Number of Bytes of information to represent an encoded video frame | | Frame period (s) | Display duration (in seconds) for a video frame, that is, inverse of frame rate (in frames/second) | | HEVC | High Efficiency Video Coding | | MVC | Multiview Video Coding | | QP | Quantization parameter | | RD curve | Rate-distortion curve, that is, plot of distortion (typically represented through PSNR video quality) | | | as a function of average video bitrate | | PSNR | Peak signal to noise ratio (dB) | | PSNR video quality (dB) | Average (mean) of PSNR values of encoded frames in a video sequence | | SVC | Scalable Video Coding | | Number of layers in hierarchical B frame structure; for dyadic hierarchy | | VD curve | Rate variability-distortion curve, that is, plot of rate variability (typically represented by CoV of frame sizes) | | | as a function of video distortion (typically represented by PSNR video quality) |
