Description
Description | Vars | Methods (details)

The Data Object contains all of the Data Packets for a file.

These Data Packets are organized in terms of increasing send times. A Data Packet can contain interleaved data from several digital media streams. This data can consist of entire objects from one or more streams. Alternatively, it can consist of partial objects (fragmentation).

Capabilities provided within the interleave packet definition include:

  • Single or multiple payload types per Data Packet
  • Fixed-size Data Packets
  • Error correction information (optional)
  • Clock information (optional)
  • Redundant sample information, such as presentation time stamp (optional)
