pixels, resolution, aspect ratios, color depth, alpha channels, pixel blending, image compositing, and even data footprint optimization（類似於圖片的概念）。

  Internet 2.0 IP infrastructure is 1536 kbits/second (1.5 MBPS, or megabits per second)。

A faster data pipe is at least 2048 kbits/s, or 2 mbits/s or 2 MBPS, and video compressed at this higher bit rate exhibits a higher visual quality level. More modern 4G networks claim to be between 3 and 6 mbits/s（3G networks deliver between 600 kbits/s and 1.5 mbits/s, so, on average, these will be 1.5 mbits/s and classified as a medium data pipe）。
