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 21):
The device according to  claim 19 , wherein,\n the second adjustment subunit ( 22 - 2 ) reallocates the second average bit rate of the positive difference value time subinterval, so as to reduce the second average bit rate of positive difference value time subinterval by at least a part of the difference value; and the first difference value allocation unit ( 202 ) increases the current value of the storage ( 201 ) by at least a part of the difference value; the second adjustment subunit ( 22 - 2 ) allocates the total saved bit rate value in the storage ( 201 ) to each negative difference value time subinterval in the following way: dividing the total bit rate value of a saving pool by the number of the each negative difference value time subintervals, so as to obtain a second average difference value; and overlaying the second average difference value on the second average bit rate of each negative difference value time subinterval.
