Trellis quantization as structured vector quantizer is able to improve the rate-distortion performance of traditional scalar quantizers. In this work, a trellis quantization option for JPEG XS is considered and analyzed; JPEG XS is a low-complexity, low-latency high-speed 'mezzanine'' codec for Video over IP transmission in professional production environments and industrial applications where high compression rates are of lesser importance than visual lossless compression at high speed.
