Moreover, the device may, in various embodiments, employ some or all of the received service listings data, channel listings data, and/or the like in presenting (e.g., via a GUI, other interface, and/or the like) one or more of the selected service listings, channel listings, and/or the like to the user. Various aspects of the present invention will now be discussed in greater detail.

Datacast Signal and Service Parameter Operations With respect to Fig. 1 it is noted that according to various embodiments of the present invention a device (e.g., a wired or wireless node and/or other computer, a television receiver, a radio receiver, and/or the like) may act to detect one or more datacast signals (e.g., Internet Protocol Datacast (IPDC) signals) (step 101). Moreover, in various embodiments, a device may act to receive one or more service parameters corresponding, for instance, to such detected signals. For example, a device may act to receive, with respect to each of one or more of the detected signals, one or more service parameters. Various data could, in various embodiments, be included in service parameters. For instance, included could be, perhaps for one or more service areas, available service information, channel information, and/or the like (perhaps corresponding to one or more subscriptions, packages, and/or the like), service area information (e.g., geographical coverage area information, service area identifiers, and/or the like), service provider descriptions (e.g., service provider names, identifiers such as widgets or icons, and/or the like), frequencies, network addresses, and/or the like for receipt service listings data, channel listings data, and/or the like, network parameters (e.g., network identifiers, network names, Network Information Table (NIT) versions, signal lists, platform lists, network addresses (e.g., an IP address), multicast addresses (e.g., an IP multicast address) and/or the like), platform parameters (e.g., platform identifiers, platform names, and/or the like), routing table parameters (e.g., routing table lists, identifiers, and/or the like), signal parameters, cell identifiers, tuning parameters, transport stream identifiers, identifiers for subscriptions, packages, and/or the like, and/or the like. Receipt of service parameters may, in various embodiments, involve Internet Protocol Datacast (IPDC) (e.g., receipt of an IPDC data stream), Universal Mobile Telecommunications Service (UMTS), General Packet Radio Service (GPRS), Short Message Service (SMS), Multimedia Messaging Service (MMS), email, Simple Object Access Protocol (SOAP), Java Messaging Service (JMS), Remote Method Invocation (RMI), Multimedia Broadcast and Multicast Service (MBMS), Digital Video Broadcast (DVB) (e.g., terrestrial digital video broadcast (DVB-T), Digital Video Broadcasting: Handhelds (DVB-H), Satellite Digital Video Broadcast (DVB-S), and/or the like), Digital Audio Broadcast (DAB), Digital Radio Mondial (DRM), Internet Protocol (IP), Amplitude Modulation (AM) radio, Frequency Modulation (FM) radio (e.g., via FM subcarrier), Radio Data System (RDS), satellite radio, television, digital television, satellite television, National Television System Committee (NTSC) television, Phase Alternating Line (PAL) television, and/or the like (e.g., via blanking interval and/or the like), and/or the like. In various embodiments, one or more service parameters may be received via receipt of one or more NITs and/or the like. In various embodiments, in receipt of service parameters, a device tuner might be set to a particular frequency, and/or the device might associate itself with a multicast address (e.g., an IP multicast address), the device might access data from a particular network address (e.g., an IP address), and/or the like. It is noted that, in various embodiments, one or more received service parameters may be stored. It is further noted that, in various embodiments, one or more received NITs may be stored. In acting to detect one or more datacast signals and/or receive one or more service parameters, the device might, for example, act to scan signals in one or more frequency ranges, perhaps taking into account one or more bandwidths. Such frequency ranges and/or bandwidths might, for instance, be set by a user, a system administrator, a manufacturer, a service provider, and/or the like. For example, in various embodiments scanning might be with respect to a frequency range of 474-858 MHz and a bandwidth of 8 MHz. It is noted that, in various embodiments, scanning may involve the interpretation of one or more NITs. In various embodiments, in scanning for datacast signals the device may act to tune to one or more of the frequencies relating to a particular frequency range and corresponding bandwidth. For instance, where the frequency range was x-y MHz and the corresponding bandwidth was z MHz, the node might act to tune to one or more of the frequencies x + a - z,

with the value of a ranging, by increments of one, from 0 to — . In various embodiments, in z acting to tune to a particular frequency, in the case where the device is unable to achieve tuning lock the device may act to skip to the next frequency in the sequence. Tuning to a particular frequency in the sequence, the device might, for example, act to create a NIT program identifier (PID) filter and/or the like, and/or to check NIT network identifier and/or the like In various embodiments, in the case where the device determines that that the NIT network identifier check has already been performed, the device may act to skip to the next frequency in the sequence. As a next step, perhaps after determining that the NIT network identifier check has not already been performed, the device may act to check for NIT linkage descriptor (e.g., OxOB) presence and/or the like. In various embodiments, in the case where the linkage descriptor and/or the like is not found, the device may act to skip to the next frequency in the sequence. In the case where the linkage descriptor and/or the like is found, the device might, in various embodiments, act to, perhaps via NIT parsing and/or the like, store one or more service parameters (e.g., for each NIT-listed signal and/or the like) (step 103). In various embodiments only service parameters associated with one or more specified platform identifiers (e.g., linkage descriptor-listed platform identifiers) might be stored. Such platform identifiers might, for instance, be specified by a user, a system administrator, a manufacturer, a service provider, and/or the like. In various embodiments, among stored service parameters may, for example, be one or more cell identifiers, network identifiers (e.g., original network identifiers, time-slice network identifiers, and/or the like), transport stream identifiers, tuning parameters, network names, widgets or icons describing networks or service providers, NIT versions, signal lists, platform lists, platform identifiers, platform names, routing table lists, signal lists, signal parameters, IP/Media Access Control (MAC) notification table program map table service identifiers, hierarchy information, hierarchy priorities, center frequencies, bandwidths, constellations, code rates, guard intervals, transmission modes, use information, frame size information, max burst duration information, and/or the like.

Offering of Service Listings, Channel Listings, and/or the Like With further respect to Fig. 1 it is noted that, according to various embodiments of the present invention, the device may, perhaps via a GUI, other interface, and/or the like act to inform its user of one or more available service listings, channel listings, service providers and/or the like, to allow its user to select one or more available service listings, channel listings, service provider listings and/or the like, and/or the like (step 105). Such functionality may be implemented in a number of ways. With respect to the exemplary interface of Fig. 2 it is noted that, in various embodiments a GUI, other interface, and/or the like (201) may be employed to present one or more, perhaps selectable, elements, widgets, icons, and/or the like (203-209) to the user. Each element, widget, icon, and/or the like might, for example, covey (e.g., via text, graphics, icons, and/or the like) an available service listing, channel listing, and/or the like. In various embodiments, text, graphics, icons, and/or the like might, alternately or additionally, be employed to convey one or more service providers, service provider names, and/or the like. In various embodiments, via, for instance, the user interacting with the GUI, other interface, and/or the like, the device could come to know service listings, channel listings, and/or the like desired by the user. Accordingly, for instance, a number of GUI checkboxes with associated appropriate text, graphics, icons, and/or the like, corresponding to available service listings, channel listings, service providers, and/or the like might be presented to the user, and the user could employ the checkboxes to indicate her selections. It is noted that, in various embodiments, one or more received service parameters may be employed. For instance, in various embodiments, one or more platforms names, platform identifiers, and/or the like may be employed in implementing one or more of the elements, widgets, icons, and/or the like (e.g., appropriate corresponding platform names, platform identifiers, and/or the like might be linked).

Service Listings Data, Channel Listings Data, and/or the Like Operations According to various embodiments, the device may act to employ appropriate received service parameters in receiving, storing, presenting and/or the like service listings data, channel listings data, and/or the like corresponding to service listings, channel listings, and/or the like selected by the user. Such functionality may be implemented in a number of ways. With respect to Fig. 3 it is noted that, for instance, the device might, in various embodiments, act to select from accessible service parameters (e.g., service parameters held in an accessible store) appropriate service parameters corresponding to the service listings, channel listings, service provider listings and/or the like selected by the user (step 301). The accessible service parameters might, in various embodiments, be associated (e.g., via lookup tables, stores, and/or the like) with available service listings, channel listings, and/or the like, and the device might employ such associations in selection. Having performed service parameter selection the device could, in various embodiments, retrieve, access, and/or the like the selected service parameters (step 303). Service parameters employable in the receipt service listings data, channel listings data, and/or the like could include, for instance, frequencies, network addresses, and/or the like, information regarding one or more subscriptions, packages, and/or the like (e.g., of the device's user), and/or the like. Receipt, using appropriate service parameters, of the service listings data, channel listings data, and/or the like corresponding to service listings, channel listings, and/or the like selected by the user (step 305) could, in various embodiments, involve IPDC, UMTS, GPRS, SMS, MMS, email, SOAP, JMS, RMI, MBMS, DVB (e.g., DVB-T, DVB-H, DVB-S, and/or the like), DAB, DRM, IP , AM radio, FM radio (e.g., via FM subcarrier), RDS, satellite radio, television, satellite television, NTSC television, PAL television, and/or the like (e.g., via blanking interval and/or the like), and/or the like. For instance, an IPDC data stream might be received, a device tuner might be set to a particular frequency, the device might access data from a particular network address (e.g., an IP address), the device might associate itself with a multicast address (e.g., an IP multicast address), and/or the like. Some or all of the received service listings data, channel listings data, and/or he like may, in various embodiments, be stored by the device (step 307). It is noted that, in various embodiments, at least some of employed service parameters, and/or received service listings data, channel listings data, and/or the like may be related to one or more-platform identifiers. It is further noted that, in various embodiments, there may be one or more service providers using multiple frequencies to make available service listings data, channel listings data, and/or the like corresponding to one or more service listings, channel listings, and/or the like.

Provision of Service Listings, Channel Listings, and/or the Like According to various embodiments of the present invention, some or all of the received service listings data, channel listings data, and/or the like may be employed in presenting to the user one or more of the selected service listings, channel listings, and/or the like. Such functionality may be implemented in a number of ways. With respect to Fig. 4 it is noted that, for example, the user may be presented with one or more of the selected service listings, channel listings, service providers listings and/or the like in the form of one or more GUIs, grids, and/or other interfaces displaying information about one or more available programs and/or the like (e.g., video, audio, and/or interactive programs), perhaps with respect to one or more particular time periods (step 401). Such a time period might, for example, be specified by the user, correlate to a current time, and/or the like. In various embodiments, indication of one or more available services, channels, and/or the like might be provided via the GUIs, grids, and/or other interfaces, with indication of one or more available programs and/or the like being presented for each service, channel, and/or the like. It is noted that, in various embodiments, the GUIs, grids, and/or other interfaces might act to display only channels, services, programs, and/or the like available in accordance with one or more subscriptions, packages, and/or the like of the user. It is further noted that the user may, in various embodiments, be able to search among available channels, services, programs, and/or the like, be able to select one or more channels, services, programs, and/or the like for receipt, recording, use, and/or the like, and/or the like (step 403). Accordingly, for instance, selection (e.g., via a provided GUI, grid, and/or other interface) of a particular program and/or the like indicated as available by a service listing, channel listing, and/or the like may result in the activation of software, circuitry, and/or the like (step 405) whereby, for example, video, audio, data, interaction, and/or the like may be presented (step 407).
