The present article describes the creation of a MPEG-2 Transport Stream (TS)/Broadcast Transport Stream (BTS) Analyzer for Digital Television. This analyzer recognizes TS and BTS files in a decimal or hexadecimal format and it shows the components of the PSI (Program Service Information)/SI (Service Information) Tables, such as: Program Association Table (PAT), Program Map Table (PMT), Network Information Table (NIT), and Service Descriptor Table (SDT); in the case of the BTS files it also shows the content of the Transmission and Multiplexing Configuration (TMCC) table. The software has a package search system where you can look for a package through his PID (Program Identification) number or his package number. It also allows surfing between all the packages or the packages with the same PID number.

This paper describes the design and implementation of a system responsible of the automotive monitoring and diagnosis of a vehicle using the standard OBDII (On Board Diagnostics), a mobile application on the Android Platform and the implementation of a Web server developed using PHP (Hypertext Preprocessor). For the development a mobile terminal Samsung Galaxy ACE, a vehicle Kia Rio R 2013 and an BAFX OBDII Bluetooth communication device were used. Also a fault code simulator was implemented to allow the system's testing without the need of a real connection with the vehicle.
