Resumen
MENA VALDES, Ana Ivis; MOREJON BETANCOURT, Dreyelian; CABRERA ALVAREZ, Rufino y HERNANDEZ SANCHEZ, Yosmany. Built-in functionalities to set-top box SDP160’s firmware for monitor signal level and signal to noise ratio of digital TV signal. EAC [online]. 2021, vol.42, n.2, pp. 17-33. Epub 09-Sep-2021. ISSN 1815-5928.
This paper describes the new functionalities introduced to the source code of the decoder box model SDP160 of the SOYEA brand to obtain, adjust and correct the Signal Level values and the Signal to Noise Ratio of the DTMB digital television signal received. (Digital Terrestrial Multimedia Broadcast) with 6 MHz channeling. These modifications to the source code of the decoder box give rise to the Tool to monitor the digital television signal. It explains the process of calibration and adjustment of these parameters. The functionalities implemented for storage are shown with flow diagrams. Moreover, it is exposed the incorporated functionalities for the analysis and display on the screen of the received signal data.
