Video encoding system and video encoding method

A video encoding system comprising:

• a central processing unit (CPU);
• a parallel processing device capable of executing parallel processing at a higher speed than the CPU;
• and
• a sequential processing device capable of executing sequential processing at a higher speed than the CPU, wherein
• the parallel processing device performs processing having a greater speed-increasing effect by performing the parallel processing among pieces of processing related to compression encoding of a video,
• the sequential processing device performs processing with a high computational load or processing that requires high-speed processing based on the sequential processing among the pieces of processing related to the compression encoding, and
• the CPU performs processing that involves a high frequency of alteration of content of an algorithm among the pieces of processing related to the compression encoding.
