The Program and System Information Protocol (PSIP) is the MPEG (Moving Picture Experts Group, a video and audio industry group) and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended for the ATSC digital television system for carrying metadata about each channel ...
The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: PAT (Program Association Table) CAT (Conditional Access Table) PMT (Program Mapping Table) NIT (Network Information Table) The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.
The PSI protocols that support one-off delegation require the data owner to re-encode its data and send the encoded data to the server for each computation, e.g.,. [7] Those that support repeated delegation allow the data owners to upload their (encrypted) data to the server only once, and then re-use it many times for each computation carried ...

Psi is a free instant messaging client for the XMPP protocol (including such services as Google Talk [4]) which uses the Qt toolkit. It runs on Linux (and other Unix-like operating systems), Windows , macOS and OS/2 [ 5 ] (including eComStation and ArcaOS ).
Psi (instant messaging client), XMPP client program Potentially Shippable Increment , in the Scrum software development methodology Program-specific information , part of the MPEG transport stream protocol
Following the goal of an open interface standard, PSI5 was developed on the basis of existing proprietary implementations of companies Autoliv, Bosch and Continental.A first common publication was released at the "Sensor" trade fair in Nuremberg in May 2005.
Psi is an ab initio computational chemistry package originally written by the research group of Henry F. Schaefer, III (University of Georgia). Utilizing Psi, one can perform a calculation on a molecular system with various kinds of methods such as Hartree-Fock , Post-Hartree–Fock electron correlation methods, and density functional theory .
