What are Encoding and Decoding?
Encoding:
Encoding is the process of converting data from one form into another form to meet certain standers, its purpose is to compress, secure and express information in a specific way/format. There are two types of Encoding Lossless and Lossy. Lossless ensures that data can be restored after the encoding and decoding process and on the other hand Lossy is the involvement of data loss during encoding. Encoding can be applied through data transfer, security and data storage.
Decoding:
Decoding is the process in which encoded data is transformed back into its original form. The purpose of Decoding is to restore data to its original form and to interpret the data/information in a specific format. The two types of decoding are Lossless and Lossy just like Encoding but they have different roles in the decoding process Lossless ensure the recovery of the original data and Lossy results in loss data during the decoding process. Decoding is applied through data Reception and Data Retrieval.
Encoding and Decoding are both essential in data processing as they complete each other in delivering and interpreting information through transformation, compression and security of data, this idea was originated from Stuart Hall in 1973.
Encoding and Decoding are the process of representing different information in various fields and recovering it. There are many different ideas and examples of Encoding and Decoding and ill be covering some.
Text Encoding/Decoding
Texts can be Encoded and Decoded by converting text in a different format and the decoding it into the original text. To help you understand it better an example would be Morse code, Baudot code, American standard code and Unicode these are all examples on how a translated message can be easily understood.
Image Encoding/Decoding
This is where images are decoded for display after they have been transformed for storage or transmission. Examples of this are PNG compression, image encryption/decryption these allow the process to be done.
Audio Encoding/Decoding
This format is when audio signals are transferred into digital forms and then are compressed and decoded into playbacks. Examples are audio encryption/decryption, MP3 compression.
Video Encoding/Decoding
This idea is to compress the video data for storage and decode it for display. Examples of video encoding/decoding include H.264, H.265, video encryption/decryption.
These are a few examples of how the encoding/decoding idea works for different purposes across a wide range of regulation.
Now ill take a look at the Key ideas of Encoding/Decoding:
Representation Transformation
Encoding involves transforming information from one representative and the other, to ensure suitable formats
Information Compression
Information Compression is used to reduce data sizing in order to allow more storage to be transmitted and processed.
Error Detection and Correction
Encoding includes mechanisms that detect and correct errors.
Security and Privacy
Encoding is crucial in securing Communication. It transforms data in a difficult form in order for it to be hard to understand.
These are a few Key ideas of Encoding/Decoding. As you can see they both work together in different ways in order to deliver and receive a message through certain process.

Hello, I want to say thank you because I could finally understand the terms!!
Your post is very useful since it is a fairly complex topic, however, all the information that I have found in your post has been very helpful to me for a better understanding. Being completely honest with you, I would have liked to see some current examples, but even so, I think you have done magnificent research.
How do you think we could relate these terms to the digital media?
I really like the detailed explanation of the concept in your blog, and the way you use a combination of graphics to show your concept clearly.Based on Stuart Hall’s idea，he regards language use as a operating with a framework of power.
Therefore, we must have a better understanding of encoding and decoding, master this theory better, and understand and use it correctly in our daily expressions. Only by understanding the media as much as possible can we avoid or reduce the control of the media power.
