TV, wtf is a "jungle IC" ????
The first step in making TVs and monitors do more with less parts involved 'hybrids'. This is where we took 30 to 100 pars, surface mount, and put then on a PCB or ceramic board. This really helped manufacturing.

The first jungle ICs I work on were 'analog'. The jungle IC will include most all the small transistors, resistors and some capacitors. These were small pin count usually below 40 pins. Most had both horizontal PLL and vertical oscillator. I designed one for Samsung that input many different typed of video and output one format. It looked for separate sync/composite sync on H&V or H. It also looked for sync on green if no digital sync was there. It also output 'blanking', 'black level', and 'color burst' timing. It was a multi format video processor for TV and VGA sets.
The early digital jungle parts from Europe had a 8051 CPU + ADC + DAC and much of the analog jungle parts. I was thinking of Philips and SG. These parts has analog DACs.
The first Samson and Sony parts had a 68HC11 CPU. The Sony's were later converted to a different CPU. These parts had PWM (digital) DACs. I managed to include (digital) ADCs that measured beam current and room brightness. We converted most analog functions to digital. By the end, some sets had a vertical power amplifier in class C (PWM).
Why: To make repair harder. lol NO. (the repair department inside the factory mostly went away)
Every year we added more functions, reduced price, reduced parts, helped failure rates, reduced factory labor greatly. The goal is to reduce the price to where there is no reason to repair. sorry---TVTech
