Huffman codes used in Indeo4 are of the form [string of k 1's][0][some additional bits]. The [string of k 1's][0] is the code prefix and the additional bits are the code bits. The same form of huffman coding was already used in Indeo 2 codec. Below an example of such a codebook:

In retrospect, the format is quite simple, but it took me some time to figure it out. Aside from the first two bytes (the segment size), and the last four bytes (which always seem to be 0), it’s a sequence of two-byte integers.

WebHuffman encoding follows from the problem described in the Data Compression section. We have a string that we want to encode into bits. Huffman encoding ensures that our encoded bitstring is as small as possible without losing any information. Webconstructs a Huffman codebook while it processes the sensor signals, without the need for performing encoding in two passes. As a consequence, neither signal buffering is required nor the transmission of a whole codebook from the encoder to the decoder, as the latter can construct the codebook inferred from the received symbols.
