Abstract


The fundamental role of the multiplexer to the multiplexer meets the standard MPEG-2 TS (transport stream) stream to be packaged in accordance with certain rules of multiplexing, in order to transmit in one of the analog bandwidth multiplexed digital programs. In addition, the provisions of the Digital Video Broadcasting Chinese business information specification and DVB-SI standard, the multiplexer into the digital television transmission system network must be carried in the transport stream the electronic program guide (EPG) information. Accordingly, the author based on the characteristics of the digital television multiplexer in NIOSII designed and implemented based on the Ethernet controller chip LAN91C111 remote control as well as EPG data into the program, improve the functionality of the multiplexer. The program will configure the system control and EPG information two functions in which the same control software, so a host can control multiple multiplexer system is highly integrated, low-cost, and highly practical. In the analysis of a digital television multiplexer based on NIOSII multiplexed basis of the principle, the major work done in this paper are as follows: (1) the embedded operating system UC / OS-II ported to the multiplexer software module and design a test program to verify the operating system after transplantation to normal operation. (2) based on MPEG-2 and DVB-SI standard C language in the FPGA's RAM among PSI / SI information tables carrying EPG information design, including the design of choice and segment descriptor. (3) at the same time need to insert the EPG information for multiplexer during transport stream multiplexing requirements of design and an Ethernet controller chip LAN91C111 multiplexer-based remote control and EPG data insertion program. The program can insert PSI / SI data via Ethernet to the multiplexer and multiplexer remote control can be achieved. (4) with VC done on the PC the multiplexer control software design and programming. Focus in the TCP / IP protocol based on the completion of a program of the host control software communication module design and gives the program flow. (5) for the insertion of the entire remote control and data programs, the design of a test system for verification. The entire test system including: control host, multiplexers, the ASI interface card, the stream acquisition card, stream analysis software. The authors designed a four-TS stream input test program, and test results are given stream analysis software. The results show that the entire system to achieve the design requirements.
