I hope you are doing well.
I am a beginner, I was working on a project in matlab and what I have to do is:
1. Read in BMP image.
2. Convert image from rgb to YCbCr.
3. Subsample image using formats 4:4:4 (no subsampling), 4:2:2 or 4:1:1.
4. Partition each plane (Y, Cb and Cr) into 8 × 8 blocks.
5. DCT transform each block.
6. Quantise th

I do not know for rgb model, but for single color 16 x 32 dot chinese led modul there is 16 pcs of 74hc595 (1/4 refresh). Each panel have 74hc245 buffer on data, clk, latch and enable line. There is one NOT gate, i think on enable line, hc138 decoder and 8 pcs dual p-channel fet transistors in SOP8 package for driving rows

A while back i bought this 3,5" TFT display that has a 24-bit rgb interface. With it I bought an analogue to 24-bit converter board.
Using an analogue signal from my TV decoder it looks pretty good, but with the analogue output from my Raspberry Pi, not so much. It's difficult to read text, and it seems like a lot of pixel information is

I would like to ask if there any available chip that can separate rgb signal from composite video(PAL or NTSC). I found some chip but most of them are obsolete.

Basically the TVP5150 need simple register setting via I2C link
The hard work is to get the data from the TVP using the STM32 digital I/O
You will need to use interrupt and DMA for trnsfering data into rgb format
All the best

Does anyone know the class of chips that takes a digital DVI/HDMI signal, and breaks it apart into parallel 24bit rgb (so 24 pins, 8 for red, 8 for green, and 8 for blue)?
Is this a decoder? Or a video interface, or what? Is this generally done on a high speed microcontroller, or is there a specific dedicated line of integrated circuits to do th

I have two 24bit rgb signals (fully synchronous). How can I mix them with
some proportion (alpha) . OR How can I build alpha blender.
