Compression Technologies


The process of combining the steams is known as multiplexing.

We are ready to Building the MPEG Bit Stream for a variety of transmitters and links  standards.

We  processed  for your design of stream parameters in order to ensure requirements for your system:

Elementary Stream (ES)

Packetised Elementary Stream (PES)

MPEG Program Stream

MPEG Transport Stream

Single and Multiple Program Transport Streams

Signalling Tables

We know how to manage Programme Service Information (SI):

PAT – Program Association Table (lists the PIDs of tables describing each programme). The PAT is sent with the well-known PID value of 0x000.
CAT – Conditional Access Table (defines type of scrambling used and PID values of transport streams which contain the conditional access management and entitlement information (EMM)). The PAT is sent with the well-known PID value of 0x001.
PMT – Program Map Table (defines the set of PIDs associated with a programme, e.g. audio, video, …)
NIT – Network Information Table (PID=10, contains details of the bearer network used to transmit the MPEG multiplex, including the carrier frequency)
DSM-CC – Digital Storage Media Command and Control (messages to the receivers)

and Service Information (SI) provided by DVB

BAT- Bouquet Association Table (groups services into logical groups)
SDT- Service Description Table (describes the name and other details of services)
TDT – Time and Date Table (PID=14, provides present time and date)
RST – Running Status Table (PID=13, provides status of a programmed transmission, allows for automatic event switching)
EIT – Event Information Table (PID=12, provides details of a programmed transmission)
