# Data table

A table that defines the data to be put in the payload portion of the RTP packet.

## Overall

This table defines various places the data can be retrieved. Table entries are listed in the following table.

|Data table entry|Bytes|
|----------------|-----|
|Data source     |1    |
|Data            |15   |

The data source field of the entry table indicates how the other 15 bytes of the entry are to be interpreted. Values of `0` through `4` are defined. The various data table formats are defined in [Data modes](/documentation/QuickTime-File-Format/Data_modes).

Although there are various schemes, note that the entries in the various schemes are the same size, 16 bytes long.
