Embodiment Construction
[0028] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] The macroblock layer code rate control method based on the H.264 video coding standard provided in this embodiment includes the following steps:
[0030] A uses the fluid blockage model and linear pursuit theory to calculate the target number of bits in the current frame;
[0031] B allocates the number of macroblock layer bits according to formula (1),
[0032] R i = a T r * [ 1 - SSIM ( i ) ] 2 Σ k ...
