Q&A

What is the purpose of rescaling in the decoder?

Rescaling is done to keep the values of a and b consistent during decoding.

How does the decoder determine the length of the encoded message?

The decoder calculates the length of the encoded message using the rescaling operations.

Why is decoding the binary sequence important in arithmetic coding?

Decoding the binary sequence allows the original source message to be recovered.

What is the role of timestamps in the video?

Timestamps help viewers locate relevant parts of the video.

Is the decoder responsible for determining the end of the encoded message?

Yes, the decoder is responsible for figuring out the end of the encoded message.
