There are two kinds of PS VITA package files (.pkg):

== Firmware Packages ==
 
PS VITA Firmware Package files (.pkg) are inside PS VITA Update Files (.pup).
 
Those packages can not be decrypted, yet.
 
== PSN ==
 
=== Game Update ===
It is a bit upgraded but basicly the same as on PS3. Once a game tab is opened, the VITA downloads a PKG for this game tab. This includes update information, such as if an update if available. If thats the case, the game tab will show you a yellow arrow on the top of the screen which gives you information about the update available.
This information is stored in XML's which are gathered via URL's like this example one:

this is the content:
<pre>
<?xml version="1.0" encoding="UTF-8"?>
<changeinfo titleid="PCSG00001">
  <changes app_ver="01.01">
    <![CDATA[

    ]]>
  </changes>
</changeinfo>
 
</pre>
 
This is the original update PKG.
