Abstract

The invention relates to a key frame such as a KeyFrameDS (200). A list of key, length, and value (KLV) attribute groups are used in the KeyFrameDS. The KeyFrameDS may be modified by changing, for example, an attribute group. This may be accomplished, for example, by changing one of its attributes, such as the value attribute.
