Digital transcoder with logo insertion |
摘要 |
A method and apparatus are disclosed by which a translucent logo is inserted into the transcoded digital bitstream of an MPEG transcoder without changing the digital nature of the bitstream. Such an MPEG transcoder has cascaded decoding and encoding sections. A translucent logo is generated and is added to the reconstructed video image produced by the decoder section of the MPEG transcoder upstream of the transcoder's encoding section. The encoding section of the transcoder then encodes the bitstream which includes the translucent logo.
