Final Project
Project description
The goal of this project is to apply systems engineering principles to develop the
scenarios and use cases, requirements and specifications, system level design, and
verification and validation of a digital video recording (DVR) system. Lastly, a subset of
a system test plan will be presented.
A DVR system is a common hardware set and service provided by cable TV companies
(i.e. Comcast, Cox, Time Warner), or 3rd
party services such as TiVo, who typically
charge a monthly fee for the service portion. The service (and corresponding hardware)
allows users to record TV, set a recording, search a schedule for programs to record, set a
schedule to record programs, watch recorded programs, watch and record live TV, and
configure the DVR system. Once the system is configured and set up, the system will run
automatically according to user settings. Goals of this project include fully identifying
the system requirements, use cases, system specifications, and validating and verifying
