WIDE-BAND MULTI-FORMAT AUDIO/VIDEO PRODUCTION SYSTEM WITH FRAME-RATE CONVERSION |
摘要 |
Wide-band multi-format audio/video production system with frame-rate conversion and methods performed by the audio/video production system. Compressed video content corresponding to an original format of a video program is processed to generate uncompressed video content in an internal format having a frame rate of 24 frames per second (fps) comprising progressive frames of pixel image data having an original pixel resolution. Progressive frames of pixel image data are buffered in a high-capacity memory buffer supporting asynchronous random read and write access. The progressive frames of pixel image data in the buffered progressive frames are processed to perform a frame-rate conversion from 24 fps to a higher output frame rate to produce progressive frames of converted video content having an uncompressed format. The progressive frames of converted video content are the stored in a compressed video format to produce a converted video program having a converted frame rate in accordance with the higher output frame rate. |
