Claim:
1. A high picture quality video streaming service system, comprising: a content server for generating a first encoding video by encoding an original video at a constant bit rate, generating a second encoding video by encoding the original video having a constant quantization parameter in 1/N of a length of a Group Of Picture (GOP) and at 1/N of a frame rate of the first encoding video, generating a streaming video using the first encoding video and the second encoding video, downloading the first encoding video, and transmitting the streaming video in real time; and a user terminal for downloading the first encoding video and playing back the downloaded first encoding video or generating a video for playback by recombining frames of the first encoding video and frames of the streaming video and playing back the generated video for playback, wherein the content server predicts structural similarity values when transmitting a frame of the first encoding video and a frame of the second encoding video as the streaming video and generates the preliminary streaming video by selecting the frame of the first encoding video or the second encoding video based on both a difference between the predicted structural similarity values and a threshold.
