    bitwise copying and pasting

    i need a help on the bitwise operations. but this a little complicated. this is bitwise copying and pasting. i need to copy a particular number of bits and paste at different loaction. eg., A stream has 1000 bits. i am copying from 102 bit to 201 bit, then pasting(overwriting) at 305 th bit...

    Information about id3v2 tags in mp3

    Re: id3v2 tags in mp3. the frame is the frame of the id3v2 tag. what happens if there is an error in the id3v2 tag. should it neglect the error without stopping the mp3 decoding. if one of the id3v2 frame is replaced with all zeros what will happen. Added after 2 hours: how is the end of...

    Information about id3v2 tags in mp3

    i am now working on designing an mp3 encoder. in that i have seen about id3v2 tags. i have the following questions in my mind abt that: 1. what is the anatomy of an mp3 file with an id3 tag. 2. how can an id3 tag be added to an mp3 file. can i add that directly in bitstream.. 3. is it...
