System Validation Of Advanced Digital Set-Top Box

Abstract

In Set Top Boxes new applications support are coming day by day. In windows it is easy to support Media apps but when it comes to open source community then there is a need of a multimedia framework which provide libraries to support applications developed on top of it. Applications just linked to plugins provided by Gstreamer to provide appropriate functionality. There are many tools provided by Gstreamer. Some of them are gst-apps, gst-inspect, gst-discoverer, gst-launch which are useful for different purposes. These make work of user much easier, like gst-launch is used for debugging purposes to create pipeline manually by connecting all elements. So, there is a need to study all these. For each and every functionality there is a need to do regression testing to check that in built functionalities are not breaking which were developed earlier. To do so some framework are designed using XML and PYTHON which are suitable to complete whole test procedure. DVR i.e. Digital Video Recording is becoming a primary requirement of user. A continuous incorporation of new features is necessary in DVR and different usecases must be tested properly. Circular Buffer is one of the new implementation of DVR by which we can see latest buffer size recording. With new improvements there comes new issues which need to be resolved. To do all such sort of testing we require to automate the test framework so that much of our time should not be wasted in doing all these. For this purpose shell and python scripting is used. Even GUIs are also prepared for same purposes.
