A system for determining compatibility between various items is disclosed. A wireless communication device is used to scan a machine-readable tag which includes a plurality of information fields. The information fields include at least identification information of the primary object to which the tag is affixed, list of compatible items, characteristic information of the primary object or other objects, etc. The scanned information from the tag is compared to information in other tags. If the at least some of the information in the tag affixed to the primary object matches the information in one or more other tags, a notification event is triggered to inform the user of the match.

Wireless association

A method of joining a first device to a radio communications network controlled by a second device without contemporaneous user input of a secret at the second device, including: storing in the second device a secret generated at the second device; making the stored secret available in the first device; and creating in the first device and in the second device, using the secret, a secret key for use in securing communication between the first and second devices.

Method and device relating to security in a radio communication network

The invention concerns a method of increasing the storage capacity of service information data (SI) in a receiver for digital TV transmissions, such as e.g. in accordance with the MPEG 2 and the DVB standard. The increase takes place to enable keeping a larger quantity of service information data ready for recall, which is used to create the display of an interactive electronic program guide that is shown as an &ldquo;On Screen Display&rdquo; (OSD) on the screen. Such a program guide is designed to make the transmission choice easier and to automate the adjustment of the receiver for the desired transmission. The object of the invention is to provide a solution which makes it possible to expand the storage capacity, especially the mentioned cache area, without additional hardware. To achieve the object the unoccupied area of the image memory (MPEG-RAM) is used as a cache area by the video decoder (V-DEC) while graphic displays are shown on the full screen surface as a &ldquo;Full Screen OSD&rdquo;. To create the electronic program guide the microcomputer (&mgr;C), which is responsible for managing the receiver, uses this cache area to buffer as large a portion as possible of the service information (SI) extracted from the receiver by a demultiplexer.
