The RCA REB1200 is an ebook reader that reads content that is either downloaded from Gemstar or copied onto its compact flash card. Softbook Publisher creates content by converting Microsoft Word documents. An alternate method for creating content is to use the program below to convert OEB files. OEB is a standard based on HTML and XML defined by the Open eBook Forum
This program converts an OEB package file (.opf) to an OEB format file (.oeb) compatible with SoftBook Personal Publisher. Combines the files of a REB1200 ebook (.RES directory) into a Softbook ebook (.imp file) for easier backup. If the REB1200 ebook is not encrypted then the Softbook ebook can be read on your computer. Creates an OEB package file from an HTML file (.odf, .htm, .html) extracting the required metadata using the same tags used in creating a RocketEdtion ebook (.rb file). Creates a list of books grouped by category. Create your own personal online bookshelf that enables you to use a web server and download books using the ethernet connection.

REB Librarian version 2.28 to create a local server for IMP files: s32reblb.zip
An .imp file consists of a header, book properties, name of .RES directory, table of contents, and the contents of each file. Version 1 is created by Softbook Publisher 1.0. Version 2 is created by Softbook Publisher 1.5. The header is the same for both versions except for the value of the version field. The versions differ in their table of contents.
Header which totals 48 bytes
offset 0x00: 2 bytes, version
offset 0x02: 8 bytes, constant "BOOKDOUG"
offset 0x0A: 8 bytes, unknown
offset 0x12: 2 bytes, count of included files
offset 0x14: 2 bytes, length of directory name
offset 0x16: 2 bytes, count of bytes remaining for header and book
properties
offset 0x18: 4 bytes, unknown
offset 0x1C: 4 bytes, unknown
offset 0x20: 4 bytes, compression off=0, on=1
offset 0x24: 4 bytes, encryption plain=0, encrypted=2
offset 0x28: 4 bytes, zoom state, both=0, small=1, large=2
offset 0x2C: 4 bytes, unknown
Book properties start at offset 0x30
ID: null terminated C string
Bookshelf Category: null terminated C string
Subcategory: null terminated C string, not displayed on
REB1200
Title: null terminated C string
Last name: null terminated C string
Middle name: null terminated C string
First name: null terminated C string
Note: Name fields are displayed in order "first middle last". Most REB1200 eBooks place the entire name in First.
Name of .RES directory
Offset to start of table of contents is 48 plus length of directory name and length of book properties. Files are included in the same order in the table of contents as the contents of the files following the table of contents. A file name of four spaces (0x20) becomes "DATA.FRK" when the .imp file is expanded into a .RES directory. The 12 bytes following "BOOKDOUG" are removed from the header and the book properties are appended and become the "RSRC.INF" file.
Table of contents for each included file except RSRC.INF:
4 bytes: file name
2 bytes: 0x0000 or 0x0001
4 bytes: file size
For each included file except RSRC.INF
4 bytes: file name
2 bytes: 0x0000 or 0x0001
4 bytes: file size
variable: contents of files
Table of contents for each included file except RSRC.INF:
4 bytes: file name
4 bytes: 0x00000000
4 bytes: file size
4 bytes: file type
4 bytes: 0x00000000
For each included file except RSRC.INF:
4 bytes: file name
4 bytes: 0x00000000
4 bytes: file size
4 bytes: file type
4 bytes: 0x00000000
variable: contents of files
This file is composed of the header and book properties sections of the .imp file with 12 bytes removed after the constant "BOOKDOUG". The identifer comes from the <dc:Identifier> element after the <dc:Identifier> element whose id attribute equals the unique-identifier attribute of the package element. If this element is not present the identifier will be a null string and the category and title of the Settings command will be changed to those of this ebook.
This file is modified after download by a number of Set-Cookie HTTP headers. The values of cookies SOURCE_ID and SOURCE_TYPE are prepended to the BOOK_ID. The bytes following first name are added including cookies ISSUE_NUMBER and CONTENT_FEED. SOURCE_ID is usually "3" and SOURCE_TYPE is usually "B".

Element text is extracted and placed in this file. Elements tags are replaced with control characters. This file can be compressed and encrypted with compression occuring before encryption. This file is compressed when the element <meta name="x-SBP-compress" content="on"/> is included in the <x-metadata> element of the package file. The compression algorithm used is LZSS. This file is encrypted when the element <meta name="x-SBP-encrypt" content="on"/> is included in the <x-metadata> element of the package file. The encryption algorithm used is DES. The 8 byte encryption key is in the SoftBook Edition Encryption Key File (.key) at offset 0x0C.
Characters less than 0x20 are removed expect for line break which is replaced with 0x20. Mutliple 0x20 characters are replaced with a single 0x20.
Control characters
0x0A end of document, forced page break
0x0B start of element except <span>
0x0D line break element <br />
0x0E start of table element <table>
0x0F image element <img />
0x13 end of table cell </td> tag
0x14 horizontal rule element <hr />
0x15 before and after page header content
0x16 before and after page footer content
When an encrypted .imp file is created the DES encryption key is stored in a file with extension .key. The DES key is used to encrypt the content of file DATA.FRK after compression. This key is encrypted with the REB1200 device key and stored in resource !!ky.
offset 0x00: 4 bytes, constant 0x00000001
offset 0x04: 4 bytes, constant 0x00000000
offset 0x08: 4 bytes, constant 0x00000001
offset 0x0C: 8 bytes, DES key
offset 0x14: 4 bytes, constant 0x00000000
A Softbook Edition file (.imp) is split into the files of a .RES directory for loading onto an REB1200 using its compact flash card. These files are named RSRC.INF, DATA.FRK and a number of files with names of four (4) uppercase letters.
Many of the file types follow a common pattern of having a 32 byte header, a variable length data section, followed by an index. A 4 byte pointer at offset 0x0A of the header points to the start of the index. The index entries point to the data in the variable length section in reverse order. Each index entry has an offset to the beginning of its data and the length of that data.
offset 0x00: 2 bytes, file version, currently version
0x0001.
offset 0x02: 4 bytes, file type
offset 0x06: 4 bytes, null
offset 0x0A: 4 bytes, offset to start of index
offset 0x0E: 18 bytes, null
offset 0x20: start of variable length data
offset 0x00: 2 bytes resource ID
offset 0x02: 4 bytes length of resource
offset 0x06: 4 bytes offset to start of resource
offset 0x0A: 2 bytes length of resource name, typically 0x0000
offset 0x0C: start of optional resource name, only included with resource of type !!sw
Each of the files whose name is four characters have a file type in them at offset 0x02 that is 4 bytes long. The minimal set of file types for a plain text file are: !!cm, !!sw, AncT, BGcl, BPgz, BPgZ, ESts, Mrgn, pInf, PPic, StRn, Styl
These types include the following:
!!cm: compression
!!ky: encryption key container
!!sw
AncT: anchor <a> elements
Ano2: annotations
AtTp
BGcl: background color
BPgz book pagination
BPgZ
BPos book position
Clos

When a Softbook Edition file (.imp) is encrypted only the DATA.FRK file is encrypted. When the same ebook is downloaded to two different REB1200 ebook readers only the 8 bytes at offset 0x02C are different. These 8 bytes are not the encryption key for the file. They are the book encryption key from file .key encrypted with the REB1200 device key. If the format version is 3 then the encrypted book key is not stored in this resource and the value of device specific key is 0. The value is 3 for books downloaded with version 3.1 of the viewer software.

The default font-size is x-small. If all the values of a style equal those of the default style a record is not created for that style.
Changing style margin-left of the <body> element changed only files of type BPgz, BPgZ, and Styl. This changed offsets 23 and 27 of the style records except for the first three. Style records are created for elements html, head, and title. A separate style record is not created for the body element.

The online bookshelf is built when the REB1200 sends an HTTP GET request to address bookshelf.softbook.net/bookshelf/default.asp. It is sent back a list of books in an HTTP response. The format of this list has Content-Type of text/x-booklist. Each line of the list is terminated by a line feed. The first line of the list is "1", which may be format version. The last line is empty so the list ends with two line feeds. The items of the list are separated by tabs
