Analysis of problems faced in Video

Overview of Video coding:

Understanding the mechanism followed in video coding:--

(a) Video Encoding
Step 1: Block matching
Step 2: Loop filter
Step 3: Prediction mode
Step 4: Prediction error
Step 5: DCT
Step 6: Quantization

(b) Video Decoding
Step 7: Inverse quantization
Step 8: VL encoding
Step 9: Multiplexing
Step 10: Channel encoding
Step 11: Inverse DCT
Step 12: Reconstruction

Analyzing the issues faced during video coding:

The video coding mechanism is built using H.26x and MPEGx algorithms.
It undergoes spatial redundancy, which can be solved through DCT coding. It also undergoes Temporal redundancy that can be solved through DPCM coding. Then, it undergoes statistical redundancy that could be solved through entropy coding.

The major issue faced in video coding is "scalability of frames", which leads to video buffering and streaming bits gets into collision.
