Abstract: A method includes: receiving a revocation list from a remote data server at a configuration device. The revocation list includes N cryptographic certificates associated with N computer software entities, respectively, that are not to be executed by any of a group of medical devices including a handheld medical device. N is an integer greater than or equal to zero The method further includes receiving data from the handheld medical device at the configuration device. The data includes a cryptographic certificate that is associated with a given computer software entity that is presently installed in memory of the handheld medical device for execution by the handheld medical device. The method further includes comparing the cryptographic certificate with the revocation list; and selectively executing a protective function by the configuration device when the cryptographic certificate is the same as one of the N cryptographic certificates of the revocation list.

Abstract: A method and apparatus for automatic display of next or future television program information when tuned to a television channel. Acquired or received program information for a television program to be shown next or later on the currently tuned television channel is automatically displayed on the currently tuned channel. In this manner, a viewer is provided with information regarding a next or future television program on the television channel currently being watched without active intervention by the viewer. According to an aspect of the invention, if a new or next television program guide or program information (update) is received before the end of a current television program, the television apparatus automatically updates the display of program information according to the information included in the newly received program guide.

Abstract: A television apparatus having digital serial bus ports allows a user to select a user-designated digital video content source input such as a digital tuner of the television apparatus and digital serial bus compliant components connected to the television apparatus via the digital serial bus ports of the television apparatus, and to cause digital content from the user-designated digital content source device to be recorded onto a digital recording device connected to the television apparatus via the digital serial bus ports. The present invention allows a user to continuously record digital content onto a digital recording device (e.g. an AVHDD), whether from the TV's digital tuner or from another digital serial bus compliant device in a peer to peer arrangement. The connection is always recording, but allows the user to select or designate a digital (i.e. MPEG2) source (i.e. the TV tuner or another digital serial bus compliant device), in addition to displaying the selected content.

Abstract: A television apparatus is operable to display table of content information from one or more peripheral devices interconnected to the television apparatus via a digital serial bus regardless of whether the television apparatus is currently tuned to the peripheral device. Particularly, table of content information is provided on a per peripheral device basis upon user request. The present invention allows the user to move through tracks of the displayed table of contents and play them, delete them, etc. The user will also be able to cycle through serial bus peripheral devices through the use of an input key on the remote, offering him easy access to multiple tables of contents, and giving the user an easy way to find a desired track. If the user has reached the last serial bus peripheral device in the serial bus list and attempts to input again, the display is wrapped back around to the first serial bus peripheral device.

Abstract: A method for performing a selectable channel search with an apparatus such as a television signal receiver provides users with flexible search options so that they may select only those search options they desire, and thereby save considerable time when performing a channel search. According to an exemplary embodiment, a method for enabling a channel search using a television signal receiver includes steps of enabling display of an on-screen menu, and enabling a user to select a plurality of options for the channel search responsive to the on-screen menu. The plurality of options includes a first option to search at least one of a plurality of inputs to the television signal receiver and a second option to search at least one of a plurality of types of channels.

Abstract: A method and apparatus enables a user to assign a given key on an input device to any specific device on a data bus network connected to the apparatus, and thereby enables the user to quickly select the specific device for control using the given key. According to an exemplary embodiment, the method includes steps of enabling a user to assign a key on an input device of the apparatus to a device on the data bus network that is indirectly connected to the apparatus, and enabling the user to select the device for control responsive to an input of the assigned key.

Abstract: An apparatus having a memory and an operating system running a plurality of applications that are controlled by user signals, means to register the user signals required by each application, means to receive user signals, and means to send each received user signal to the application registered to require that signal. A method of passing user signals to a plurality of applications running with an operating system comprising receiving from each application information on user signals required by that application; saving in a memory the required user signals associated with each application; receiving a user signal from a user interface device; retrieving from the memory applications that require the received user signal; and sending the received user signal to each of the retrieved applications.
