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 19):
The device according to  claim 18 , wherein the first adjustment subunit ( 22 - 1 ) performs bit rate allocation in the following way:\n dividing the difference value of the current time subinterval by N to obtain a first average difference value; and overlaying the first average difference value on the second average bit rate of each time subinterval in the N time subintervals after the time subinterval; the second adjustment subunit ( 22 - 2 ) further comprises: a storage ( 201 ), configured to store the saved bit rate value; a first difference value allocation unit ( 202 ), configured to, for each positive difference value time subinterval when the difference value is positive, store at least a part of the difference value into the storage ( 201 ); and a second adjustment subunit ( 22 - 2 ), configured to, for each negative difference value time subinterval when the difference value is negative, allocate the total saved bit rate value of the storage ( 201 ) to each negative difference value time subinterval.
