Seamless Concatenation - a 21st Century Dream
نویسنده
چکیده
This paper is about ‘seamless concatenation’ in the world of compressed television signals, especially MPEG2 signals, in the context of the session title ‘How tightly can we squeeze?’. The paper title has a deliberate ambiguity. It can mean the seamless concatenation of MPEG2 bitstreams to create a splice or edit, for example to insert an advertisement into an existing bitstream. It can also mean seamless or ‘lossless’ concatenation of compression coding and decoding operations in a complex broadcast processing chain. Both are a ‘dream’ in the sense that it would be desirable to perform seamless concatenation, while most embodiments of the MPEG2 standard fail to make it possible without severely restricting flexibility or compromising on the bitrate savings available from efficient compression.
