Video stream processing apparatus and video stream processing method

摘要

An image-quality control information adding section 13 reads image-quality control information corresponding to a type of an input video stream 101 from an image-quality control information storage section 12 , and then adds the read image-quality control information to the video stream 101 . A recording section 43 records a video stream 104 with the image-quality control information added thereto. An image-quality control information extracting section 22 extracts a video profile 202 from the video stream 201 read from the recording section 43 . Based on the video stream after the video profile 202 is extracted, a decoding section 23 obtains a video signal 205 . An image quality adjusting section 24 adjusts the characteristic of the video signal 205 based on the video profile 202 , and then outputs the adjustment results as a video signal 206 after image quality adjustment.
