1. A method comprising:
- coding of each tile of an input codestream;
outputting a plurality of packets of said each tile as part of an output codestream as a first complete tile-part;
storing remaining layers of said each tile in a buffer; and
outputting additional packets of said each tile from the remaining layers as a second complete tile-part.

Abstract
A method and apparatus for outputting a codestream as multiple tile-part outputs with packets from tiles being output in each tile-part is described. In one embodiment, the method comprises coding of each tile of an input codestream, outputting packets of each tile as part of an output codestream as a first complete tile-part, storing remaining layers of each tile in a buffer, and outputting additional packets of each tile from the remaining layers as a second complete tile-part.

10. A method comprising:
-
compressing a bitstream to create an original compressed codestream;
performing rate control on the original compressed codestream to created a new compressed codestream in response to a request by selecting a number of layers to remain in the codestream, including a parser using a packet structure containing a selection flag and setting a selection flag for each packet of the original codestream to a predetermined value to indicate whether said each packet is to be included in the new compressed codestream. - View Dependent Claims (11, 12, 13, 14, 18, 19)

-
means for compressing a bitstream to create an original compressed codestream;
means for performing rate control on the original compressed codestream to created a new compressed codestream in response to a request by selecting a number of layers to remain in the codestream, including a parser to use a packet structure containing a selection flag and to set a selection flag for each packet of the original codestream to a predetermined value to indicate whether said each packet is to be included in the new compressed codestream to control whether individual layers are included in the new compressed codestream. - View Dependent Claims (16, 17)
