Abstract

The MPEG system used for transmission in digital television works on the principles of transmitting small packets of information in larger chunks as in “data pipes.” Using this kind of “packetized interface” single carriers can carry several channels of digital television and this service is called “bouquet.” Understanding the MPEG – II multiplex requires understanding of the packetized elementary stream packet format, transport stream, packet synchronization, packet identification, program association tables, and map tables. For proper transmission of the packets proper error management and handling also plays an important role. This chapter focuses on the use of coding systems to enhance the viewer experience at large. The system of conditional access will be in alignment with the view of larger organizations who aim to make huge profits out of on demand viewing as with this viewers will receive the services only after making due payments. MPEG- II data can be carried to distances using the synchronous parallel interface (SPI), the synchronous serial interface (SSI), and the asynchronous serial interface (ASI).
