Mpeg-2 Ts Multiplexer in Fpga Technology

This paper discusses design and testing of a Moving Picture Experts Group 2 (MPEG-2) Transport Stream (TS) multiplexer in Field Programmable Gate Array (FPGA) technology that would transmit multiplexed packets via Ethernet. Multiplexer is designed in accordance with standard ISO/ IEC 13818-1, thus it is fully compatible with standard players. The digital design is very flexible since adding additional payload sources is effortless. Use of a microprocessor has been dropped since it often provokes non-deterministic situations, hence the design is very robust yet fully programmable. Podatkovni multiplekser MPEG-2 TS v vezju FPGA Kjučne besede: Moving Picture Experts Group 2 (MPEG-2) transportni pretok, podatkovni multiplekser, Field Programmable Gate Array (FPGA), video, Ethernet. Izvleček: V članku je predstavljen razvoj in preizkušanje podatkovnega multiplekserja za transportni pretok Moving Picture Experts Group 2 (MPEG-2 TS) v tehnologiji Field Programmable Gate Array (FPGA), ki oddaja multipleksirane podatkovne pakete prek omrežja Ethernet. Multiplekser je izdelan v skladu s standardom ISO/IEC 13818-1, zaradi česar je popolnoma kompatibilen s standardnimi predvajalniki. Digitalno vezje je zelo fleksibilno, saj je vključevanje dodatnih podatkovnih virov enostavno. Uporaba mikroprocesorja je bila opuščena, saj ta pogosto izzove nedeterministične situacije. Vezje je torej zelo robustno, vendar še vedno popolnoma programabilno.
