The compression ratio for such dictionary-based methods is, therefore, proportional to the frequency of occurrences of octet patterns in the uncompressed stream. After compression, a compressed bytestream is composed of two types of elements: data blocks and block references. A data block contains an uncompressed block of octets. On the other hand, a block reference is used to identify a sequence of octets in the uncompressed stream in order to repeat the identified sequence simply by referring to it. Figure 4.15 shows an example of a compressed bytestream structure. The data block is composed of a length and a payload. The length indicates the payload length in octets. The payload contains a sequence of up to 127 octets. The structure of a data block is shown in Figure 4.16. The block reference is composed of a repeated block length followed by a block location offset. The block reference is structured as shown in Figure 4.17. A data block contains a block of uncompressed information. The value of the first bit differentiates a data block from a block reference. The value of the first bit differentiates a data block from a block reference. Uncompressed stream ... Pattern 1 ... Pattern 1 ... Pattern 2 ...
