Abstract: A fax selective call receiver system (10) featuring compression of a fax message with an optimal one of a plurality of compression code-books (50). At least a portion (44) of a source document (26) is compressed with each of a plurality of code-books (50), and the smallest resulting data file is selected as the optimal compressed file. The compressed data file is transmitted to a selective call receiver (40) together with an index identifying the optimal code-book. The selective call receiver (40) stores each of the plurality of code-books and accesses the particular code-book for decompressing the data file on the basis of the received index. In an alternative embodiment, the fax message is divided into composing segments (SI1, SI2 and SI3), and each segment is compressed with each code-book to determine the optimal code-book for each segment.

Abstract: A selective call communication system (10), receives a facsimile (FAX) image to be delivered to at least one selective call receiver (40) capable of receiving the FAX image, has a receiver (22, 38) to receive the FAX image and a processor (20), coupled to the receiver (22, 38), to process the FAX image. The processor (20) has an optical character recognizer (OCR) (206) to recognize characters in the FAX image, a segmenter (208) to identify and mark at least one textual region (42) of the FAX image having the characters recognized by the OCR (206) and an extractor (210) to extract the at least one textual region (42) from the FAX image. The FAX image remaining forms a graphics region. A compressor (212) compresses the graphics region, an encoder (214) encodes the graphics region (44) and the at least one textual region (42) to form a hyperFAX and a transmitter (216) transmits the hyperFAX to an at least one selective call receiver (40).

Abstract: A method, in a data communication receiver having a display, for processing received information comprises the steps of receiving (1100) an address, wherein the address is associated with a plurality of image data values, and comparing (1105) the address with stored addresses to determine which one of the stored addresses is equivalent to the address. The method further comprises the step of retrieving (1105) from memory a group of column values associated with the one of the stored addresses which is equivalent to the address, wherein the group of column values is stored in a form suitable for active-addressing columns of the display.

Abstract translation: 一种用于处理接收到的信息的具有显示器的数据通信接收机的方法包括以下步骤：接收（1100）地址，其中所述地址与多个图像数据值相关联，并且将所述地址与存储的地址进行比较（1105） 以确定哪个存储的地址等同于该地址。 该方法还包括从存储器检索（1105）与存储的地址之一相关联的一列列值，其等同于地址，其中列值组以适合于主动寻址列的形式存储 的显示。
