METHOD AND DEVICE FOR COMPRESSED DOMAIN VIDEO EDITING |
摘要 |
<p>When a video stream is edited in compressed domain to achieve video editing effects, the edited bitstream may violate the receiver buffer fullness requirement. In order to comply with the buffer fullness requirement, buffer parameters in the bitstream and the file format are adjusted to ensure that the buffer will not become underflow or overflow due to video editing. As such, re-encoding the entire bitstream is not needed. If the editing effect is a slow-motion effect, a fast motion effect or a black-and-white effect, the buffer parameter to be adjusted can be the transmission rate. If the editing effect is a black-and-white effect, a cutting effect, a merging effect or a fading effect, the compressed frame sized can be adjusted.</p> |
