A Fast MB Mode Decision Algorithm for MPEG-2 to H.264 P-Frame Transcoding
Abstract--The H.264 standard achieves much higher coding efficiency than the MPEG-2 standard, due to its improved inter-and intra-prediction modes at the expense of higher computat...

Key Techniques of Bit Rate Reduction for H.264 Streams
In previous techniques of bit rate reduction transcoding, reusing the mode of the input MB is widely adopted. However, directly re-using the mode of input MB will cause additional ...
