In intraframe coding, how are redundant pixel arrays transmitted?

In intraframe coding, redundant pixel arrays are transmitted once along with their positional data for the decoder. This approach is effective because intraframe coding compresses video by encoding each frame independently, which retains a complete reference for that frame within the encoded data. By providing positional data, the decoder can accurately reconstruct the frame's appearance by knowing where each pixel belongs, thus avoiding the need for multiple transmissions of the same pixel information. This efficiency maximizes the use of bandwidth while ensuring that the video quality remains intact, as each frame is reconstructed accurately based on the received data. This method contrasts with other options, such as transmitting multiple times for accuracy, which would unnecessarily increase bandwidth usage, or not transmitting redundant data at all, which could lead to loss of crucial frame details during decoding.
