Abstract:
The disclosure discloses a video bit rate control method and a video coding device. The method includes: according to a pre-set first bit rate value and a code size generated in a previous period of time, a first quantization parameter is generated (S 1 ); according to a pre-set second bit rate value and the code size generated in the previous period of time, a second quantization parameter is generated (S 2 ); the first quantization parameter is composed with the second quantization parameter (S 3 ); if the first quantization parameter is greater than or equal to the second quantization parameter, an image frame in a current period of time is coded by using the first quantization parameter (S 4 ); and if the first quantization parameter is less than the second quantization parameter, the image frame in the current period of time is coded by using the second quantization parameter (S 5 ).

Claim (Index 23):
The device according to  claim 19 , wherein,\n the second adjustment subunit ( 22 - 2 ) further comprises a second difference value allocation unit ( 203 ), configured to calculate a difference value ratio of the difference value of each negative difference value time subinterval to the total difference value of all the negative difference value time subintervals, and multiply the total saved bit rate value in the storage ( 201 ) by the difference value ratio of each negative difference value time subinterval, so as to obtain a saved bit rate allocation value of each negative difference value time subinterval; and the second adjustment subunit ( 22 - 2 ) respectively overlays each saved bit rate allocation value on the second average bit rate of its corresponding time subinterval.
