The digitization of the processes carried out by the old JUNGLA chip and its integration with the MICROPROCESSOR and SCALER have resulted in modern televisions being, more than a circuit, a FIRMWARE that only requires the modification of a CODE recorded in a memory, when improvements are needed. This avoids having to change the circuits each time a modification is made. We will now see the operation of the MAIN board on a current television in this new series of videos. This channel thanks the engineer Luis Fernando Bustamante, from Electrónica Busher's, for his noble gesture and altruism in willingly sharing his knowledge with the community of Electronic technicians.
To reinforce the concept of FIRMWARE, an analogy is made with "operating system" and "software", but what is stored in the memories of the MAIN board is partly software that is used to surf the Internet, such as RU-vid or other applications on the Internet. tv and that they work entirely inside the one chip, all this software works on the television's operating system and that as we have already said it can be TEZEN or WEB OS or others. the other part is the FIRMWARE, which is the one that controls the MAIN circuit, so from now on we will talk about FIRMWARE, understanding that there is also part of software with an operating system within the memories. This will be more fully explained in the next video.
