Abstract
Developing innovative applications in the field of broadcasting can be challenging for several reasons. An increased democratization of broadcasting transmission equipment is highly desirable to foster the development of new services. This paper presents the system integration of a full real-time Digital Audio Broadcasting (DAB) transmission chain that runs from a single live CD. A particular effort was done to reuse and combine the key building blocks required to build this system. First, system components needed to build the DAB transmission system are identified. On one hand, a generic PC, the Universal Software Radio Peripheral (USRP) and a generic G.703 network device are selected as the base hardware. On the other hand, GNU Radio and other software modules are used. Second, the integration method based on open source software is described. A customization tool is used to adapt a Ubuntu installable live CD. The resulting disk image was tested on different platforms including desktops, laptops and virtual machines. The system worked on every tested platform that could also run the original base Ubuntu live CD. Joint use of the live CD, a USB key and a laptop proved to be a very convenient way to build portable and easy to use demonstration of the DAB technology.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
