1. a video encoder, comprising:

  • for the Part I as described video-frequency band entirety, defines the device of multiple characteristic values of first group of transmission bit rate;

    For the described Part I of described video-frequency band, define the device of multiple characteristic values of second group of buffer size;

    Define the 3rd group until present the device of multiple characteristic values of the delay of the described Part I of described video-frequency band;

    One in one in described first class value, in described second class value one and described 3rd class value is selected respectively, with the device making described Part I not have underflow condition and overflow situation for described Part I;

    Define the 4th group until present the device of multiple characteristic values of the delay of the Part II of described video-frequency band, wherein said Part II is the later part in the assigned position of described Part I;

    WithOne in one in described first class value, in described second class value one and described 4th class value is selected respectively for described Part II, with the device making the described Part II of described video-frequency band not have underflow condition and overflow situation, one in one in described first class value wherein selected for described Part II and described second class value remains unchanged relative in described first class value selected for described Part I and described second class value respectively.
