Encoded stream generating apparatus and method, data transmission system and method, and editing system and method

摘要

A method and apparatus for generating an encoded data stream representing a number of pictures or frames and having a number of layers including a picture layer in which time code information attached to the original data is described or inserted therein for each picture. Such time code information may be inserted into a user data area of the picture layer of the encoded data stream.

1. A method for generating an encoded video stream, comprising:
extracting original time code information including Linear Time Code (LTC) and Vertical Interval Time Code (VITC) that is associated with a corresponding frame of unencoded source video data; generating encoded video data from the unencoded source video data to generate an encoded video stream; and subsequently inserting the extracted original time code information into a user data area of a particular picture layer of said encoded video stream, wherein the particular picture layer is associated with the corresponding frame of the source video data, wherein the original time code information associated each frame of the source video data is attached to the corresponding frame of the encoded video data, wherein the original time code information is defined by a time_code ( ) function indicated by a user_data ( ) function.
