MPEG2 is an enhanced form of MPEG1. (It even includes MPEG1 headers in the data stream) Major improvments include prediction modes, Intra VLC table, DC precision, and non-linear macroblock quant. These results in a higher quality video, though at the expense of additional encoding/decoding power.

Quality Comparison

  • At 3Mbps it's equivilent of professional broadcast NTSC
  • At 4Mpps it's equivilent to professional broadcast PAL
