Encoding device and method, decoding device and method, editing device and method, recording medium, and program

摘要

The present invention relates to an encoding device and a method, a decoding device and a method, an editing device and a method, a storage medium, and a program which can perform encoding and decoding so that buffer failure does not occur. Information, such as a minimum bit rate, a minimum buffer size, and a minimum initial delay time, is contained in a random access point header contained in an accessible point in a bitstream. A bitstream analyzing unit 72 analyzes an input bitstream, sets the above-mentioned information, and outputs the resulting information to a buffer-information adding unit 73. The buffer-information adding unit 73 adds the input information to the input bitstream and outputs the resulting bitstream. The present invention is applicable to an encoding device and a decoding device which process bitstreams.

主权项

1. An electronic device comprising:
means for reading first buffer characteristic information contained in a first header of a first bit stream and second buffer characteristic information contained in a second header of a second bit stream; means for determining whether a first characteristic curve created based on the first buffer characteristic information contained in the first header of the first bit stream, a first decoder size, and a first decoder bit rate is always located above or is the same as a second characteristic curve created based on the second buffer characteristic information contained in the second header of the second bit stream, the first decoder size, and the first decoder bit rate; and means for replacing a portion of the first bitstream with a portion of the second bitstream when the means for determining determines that the first characteristic curve is always located above or is the same as the second characteristic curve.
