In other words, the non-existent stream 0 forms the root of the tree." All dependent streams are allocated an integer weight between 1 to 256 (inclusive)... Streams with the same parent SHOULD be allocated resources proportionally based on their weight. " In other words, if you don't care about dependencies, then don't assign the parent. Doing so will make all streams children of the root of the tree (0x0), and from there you can use weights to assign relative priority. Hope that makes sense. ig
