       FIELD OF THE INVENTION 
       [0003]    Certain embodiments of the invention relate to communication of information via a plurality of different networks. More specifically, certain embodiments of the invention relate to a method and system for providing broadcast services through a cellular and/or Wireless Network to a plurality of mobile devices via service provider integration. 
       BACKGROUND OF THE INVENTION 
       [0004]    Broadcasting and telecommunications have historically occupied separate fields. In the past, broadcasting was largely an “over-the-air” medium while wired media carried telecommunications. That distinction may no longer apply as both broadcasting and telecommunications may be delivered over either wired or wireless media. Present development may adapt broadcasting to mobility services. One limitation has been that broadcasting may often require high bit rate data transmission at rates higher than could be supported by existing mobile communications networks. However, with emerging developments in wireless communications technology, even this obstacle may be overcome. 
         [0005]    Terrestrial television and radio broadcast networks have made use of high power transmitters covering broad service areas, which enable one-way distribution of content to user equipment such as televisions and radios. By contrast, wireless telecommunications networks have made use of low power transmitters, which have covered relatively small areas known as “cells”. Unlike broadcast networks, wireless networks may be adapted to provide two-way interactive services between users of user equipment such as telephones and computer equipment. 
         [0006]    The introduction of cellular communications systems in the late 1970&#39;s and early 1980&#39;s represented a significant advance in mobile communications. The networks of this period may be commonly known as first generation, or “1G” systems. These systems were based upon analog, circuit-switching technology, the most prominent of these systems may have been the advanced mobile phone system (AMPS). Second generation, or “2G” systems ushered improvements in performance over 1G systems and introduced digital technology to mobile communications. Exemplary 2G systems include the global system for mobile communications (GSM), digital AMPS (D-AMPS), and code division multiple access (CDMA). Many of these systems have been designed according to the paradigm of the traditional telephony architecture, often focused on circuit-switched services, voice traffic, and supported data transfer rates up to 14.4 kbits/s. Higher data rates were achieved through the deployment of “2.5G” networks, many of which were adapted to existing 2G network infrastructures. The 2.5G networks began the introduction of packet-switching technology in wireless networks. However, it is the evolution of third generation, or “3G” technology that may introduce fully packet-switched networks, which support high-speed data communications. 
         [0007]    The general packet radio service (GPRS), which is an example of a 2.5G network service oriented for data communications, comprises enhancements to GSM that required additional hardware and software elements in existing GSM network infrastructures. Where GSM may allot a single time slot in a time division multiple access (TDMA) frame, GPRS may allot up to 8 such time slots providing a data transfer rate of up to 115.2 kbits/s. Another 2.5G network, enhanced data rates for GSM evolution (EDGE), also comprises enhancements to GSM, and like GPRS, EDGE may allocate up to 8 time slots in a TDMA frame for packet-switched, or packet mode, transfers. However, unlike GPRS, EDGE adapts  8  phase shift keying (8-PSK) modulation to achieve data transfer rates that may be as high as 384 kbits/s. 
         [0008]    The universal mobile telecommunications system (UMTS) is an adaptation of a 3G system, which is designed to offer integrated voice, multimedia, and Internet access services to portable user equipment. The UMTS adapts wideband CDMA (W-CDMA) to support data transfer rates, which may be as high as 2 Mbits/s. One reason why W-CDMA may support higher data rates is that W-CDMA channels may have a bandwidth of 5 MHz versus the 200 kHz channel bandwidth in GSM. A related 3G technology, high speed downlink packet access (HSDPA), is an Internet protocol (IP) based service oriented for data communications, which adapts W-CDMA to support data transfer rates of the order of 10 Mbits/s. HSDPA achieves higher data rates through a plurality of methods. For example, many transmission decisions may be made at the base station level, which is much closer to the user equipment as opposed to being made at a mobile switching center or office. These may include decisions about the scheduling of data to be transmitted, when data are to be retransmitted, and assessments about the quality of the transmission channel. HSDPA may also utilize variable coding rates in transmitted data. HSDPA also supports 16-level quadrature amplitude modulation (16-QAM) over a high-speed downlink shared channel (HS-DSCH), which permits a plurality of users to share an air interface channel. 
         [0009]    The multiple broadcast/multicast service (MBMS) is an IP datacast service, which may be deployed in EDGE and UMTS networks. The impact of MBMS is largely within the network in which a network element adapted to MBMS, the broadcast multicast service center (BM-SC), interacts with other network elements within a GSM or UMTS system to manage the distribution of content among cells within a network. User equipment may be required to support functions for the activation and deactivation of MBMS bearer service. MBMS may be adapted for delivery of video and audio information over wireless networks to user equipment. MBMS may be integrated with other services offered over the wireless network to realize multimedia services, such as multicasting, which may require two-way interaction with user equipment. 
         [0010]    Standards for digital television terrestrial broadcasting (DTTB) have evolved around the world with different systems being adopted in different regions. The three leading DTTB systems are, the advanced standards technical committee (ATSC) system, the digital video broadcast terrestrial (DVB-T) system, and the integrated service digital broadcasting terrestrial (ISDB-T) system. The ATSC system has largely been adopted in North America, South America, Taiwan, and South Korea. This system adapts trellis coding and 8-level vestigial sideband (8-VSB) modulation. The DVB-T system has largely been adopted in Europe, the Middle East, Australia, as well as parts of Africa and parts of Asia. The DVB-T system adapts coded orthogonal frequency division multiplexing (COFDM). The ISDB-T system has been adopted in Japan and adapts bandwidth segmented transmission orthogonal frequency division multiplexing (BST-OFDM). The various DTTB systems may differ in important aspects; some systems employ a 6 MHz channel separation, while others may employ 7 MHz or 8 MHz channel separations. Planning for the allocation of frequency spectrum may also vary among countries with some countries integrating frequency allocation for DTTB services into the existing allocation plan for legacy analog broadcasting systems. In such instances, broadcast towers for DTTB may be co-located with broadcast towers for analog broadcasting services with both services being allocated similar geographic broadcast coverage areas. In other countries, frequency allocation planning may involve the deployment of single frequency networks (SFNs), in which a plurality of towers, possibly with overlapping geographic broadcast coverage areas (also known as “gap fillers”), may simultaneously broadcast identical digital signals. SFNs may provide very efficient use of broadcast spectrum as a single frequency may be used to broadcast over a large coverage area in contrast to some of the conventional systems, which may be used for analog broadcasting, in which gap fillers transmit at different frequencies to avoid interference. 
         [0011]    Even among countries adopting a common DTTB system, variations may exist in parameters adapted in a specific national implementation. For example, DVB-T not only supports a plurality of modulation schemes, comprising quadrature phase shift keying (QPSK), 16-QAM, and 64 level QAM (64-QAM), but DVB-T offers a plurality of choices for the number of modulation carriers to be used in the COFDM scheme. The “2K” mode permits 1,705 carrier frequencies that may carry symbols, each with a useful duration of 224 μs is for an 8 MHz channel. In the “8K” mode there are 6,817 carrier frequencies, each with a useful symbol duration of 896 μs for an 8 MHz channel. In SFN implementations, the 2K mode may provide comparatively higher data rates but smaller geographical coverage areas than may be the case with the 8K mode. Different countries adopting the same system may also employ different channel separation schemes. 
         [0012]    While 3G systems are evolving to provide integrated voice, multimedia, and data services to mobile user equipment, there may be compelling reasons for adapting DTTB systems for this purpose. One of the more notable reasons may be the high data rates that may be supported in DTTB systems. For example, DVB-T may support data rates of 15 Mbits/s in an 8 MHz channel in a wide area SFN. There are also significant challenges in deploying broadcast services to mobile user equipment. Many handheld portable devices, for example, may require that services consume minimum power to extend battery life to a level which may be acceptable to users. Another consideration is the Doppler effect in moving user equipment, which may cause inter-symbol interference in received signals. Among the three major DTTB systems, ISDB-T was originally designed to support broadcast services to mobile user equipment. While DVB-T may not have been originally designed to support mobility broadcast services, a number of adaptations have been made to provide support for mobile broadcast capability. The adaptation of DVB-T to mobile broadcasting is commonly known as DVB handheld (DVB-H). 
         [0013]    To meet requirements for mobile broadcasting the DVB-H specification may support time slicing to reduce power consumption at the user equipment, addition of a 4K mode to enable network operators to make tradeoffs between the advantages of the 2K mode and those of the 8K mode, and an additional level of forward error correction on multiprotocol encapsulated data—forward error correction (MPE-FEC) to make DVB-H transmissions more robust to the challenges presented by mobile reception of signals and to potential limitations in antenna designs for handheld user equipment. DVB-H may also use the DVB-T modulation schemes, like QPSK and 16-quadrature amplitude modulation (16-QAM), which may be most resilient to transmission errors. MPEG audio and video services may be more resilient to error than data, thus additional forward error correction may not be required to meet DTTB service objectives. 
         [0014]    Time slicing may reduce power consumption in user equipment by increasing the burstiness of data transmission. Instead of transmitting data at the received rate, under time slicing techniques, the transmitter may delay the sending of data to user equipment and send data later but at a higher bit rate. This may reduce total data transmission time over the air, time, which may be used to temporarily power down the receiver at the user equipment. Time slicing may also facilitate service handovers as user equipment moves from one cell to another because the delay time imposed by time slicing may be used to monitor transmitters in neighboring cells. The MPE-FEC may comprise Reed-Solomon coding of IP data packets, or packets using other data protocols. The 4K mode in DVB-H may utilize 3,409 carriers, each with a useful duration of 448 μs for an 8 MHz channel. The 4K mode may enable network operators to realize greater flexibility in network design at minimum additional cost. Importantly, DVB-T and DVB-H may coexist in the same geographical area. Transmission parameter signaling (TPS) bits that are carried in the header of transmitted messages may indicate whether a given DVB transmission is DVB-T or DVB-H, in addition to indicating whether DVB-H specific features, such as time slicing, or MPE-FEC are to be performed at the receiver. As time slicing may be a mandatory feature of DVB-H, an indication of time slicing in the TPS may indicate that the received information is from a DVB-H service. 
         [0015]    Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

In this regard, the terrestrial broadcaster network  102  may comprise suitable high-speed or broadband interfaces that may be utilized to facilitate transfer of the DTV channels from the terrestrial broadcast network  102  to the service provider.

The cellular network may be utilized to offer bidirectional services via uplink and downlink communication channels, while the B-UMTS or MBMS network may be utilized to provide a unidirectional broadband services via a downlink channel. The B-UMTS or MBMS unidirectional downlink channel may be utilized to broadcast content media and/or multimedia type information to the mobile terminals  116   a  and  116   b . Although MBMS provides only unidirectional downlink communication, the invention may be not so limited. In this regard, other bidirectional communication methodologies comprising uplink and downlink capabilities, whether symmetric or asymmetric, may be utilized. 
         [0045]    Although the wireless service provider network  104  is illustrated as a GSM, CDMA, WCDMA based network and/or variants thereof, the invention is not limited in this regard. Accordingly, the wireless service provider network  104  may be an 802.11 based wireless network or wireless local area network (WLAN). The wireless service provider network  104  may also be adapted to provide 802.11 based wireless communication in addition to GSM, CDMA, WCDMA, CDMA2000 based network and/or variants thereof. In this case, the mobile terminals  116   a ,  116   b  may also be compliant with the 802.11 based wireless network. 
         [0046]    In accordance with an exemplary embodiment of the invention, if the mobile terminal (MT)  116   a  is within an operating range of the VHF/UHF broadcasting antenna  112   a  and moves out of the latter&#39;s operating range and into an operating range of the VHF/UHF broadcasting antenna  112   b , then VHF/UHF broadcasting antenna  112   b  may be adapted to provide VHF/UHF broadcast services to the mobile terminal  116   a . If the mobile terminal  116   a  subsequently moves back into the operating range of the VHF/UHF broadcasting antenna  112   a , then the broadcasting antenna  112   a  may be adapted to provide VHF/UHF broadcasting service to the mobile terminal  116   a . In a somewhat similar manner, if the mobile terminal (MT)  116   b  is within an operating range of the VHF/UHF broadcasting antenna  112   b  and moves out of the latter&#39;s operating range and into an operating range of the broadcasting antenna  112   a , then the VHF/UHF broadcasting antenna  112   a  may be adapted to provide VHF/UHF broadcasting service to the mobile terminal  116   b . If the mobile terminal  116   b  subsequently moves back into the operating range of broadcasting antenna  112   b , then the VHF/UHF broadcasting antenna  112   b  may be adapted to provide VHF/UHF broadcast services to the mobile terminal  116   b.    
         [0047]    The service provider  106  may comprise suitable interfaces, circuitry, logic and/or code that may be adapted to facilitate communication between the terrestrial broadcasting network  102  and the wireless communication network  104 . In an illustrative embodiment of the invention the service provider  106  may be adapted to utilize its interfaces to facilitate exchange control information with the terrestrial broadcast network  102  and to exchange control information with the wireless service provider  104 . The control information exchanged by the service provider  106  with the terrestrial broadcasting network  102  and the wireless communication network  104  may be utilized to control certain operations of the mobile terminals, the terrestrial broadcast network  102  and the wireless communication network  104 . 
         [0048]    In accordance with an embodiment of the invention, the service provider  106  may also comprise suitable interfaces, circuitry, logic and/or code that may be adapted to handle network policy decisions. For example, the service provider  106  may be adapted to manage a load on the terrestrial broadcast network  104  and/or a load on the wireless service provider network  104 . Load management may be utilized to distribute the flow of information throughout the terrestrial broadcast network  104  and/or a load on the wireless service provider network  104 . For example, if information is to be broadcasted via the wireless service provider network  104  to a plurality of mobile terminals within a particular cell handled by the base station  104   a  and it is determined that this may overload the wireless service provider network  104 , then the terrestrial broadcast network  102  may be configured to broadcast the information to the mobile terminals. 
         [0049]    The service provider  106  may also be adapted to handle certain types of service requests, which may have originated from a mobile terminal. For example, the mobile terminal  116   a  may request that information be delivered to it via a downlink VHF/UHF broadcast channel. However, a downlink VHF/UHF broadcast channel may be unavailable for the delivery of the requested information. As a result, the service provider  106  may route the requested information through an MBMS channel via the base station  104   c  to the mobile terminal  116   a . The requested information may be acquired from the content source  114  and/or the portal  108 . In another example, the mobile terminal  116   b  may request that information be delivered to it via a downlink cellular channel. However, the service provider  106  may determine that delivery of the information is not critical and/or the cheapest way to deliver to the mobile terminal  116   b  is via a downlink VHF/UHF broadcast channel. As a result, the service provider  106  may route the requested information from the portal  108  or content service  114  to the mobile terminal  116   b . The service provider  106  may also have the capability to send at least a portion of information to be delivered to, for example, mobile terminal  116   a  via the VHF/UHF broadcast channel and a remaining portion of the information to be delivered via the cellular broadcast channel. 
         [0050]    The portal  108  may comprise suitable logic, circuitry and/or code that may be adapted to provide content media to the service provider  106  via one or more communication links. These communication links, although not shown, may comprise wired and/or wireless communication links. The content media that may be provided by the portal  108  may comprise audio, data, video or any combination thereof. In this regard, the portal  108  may be adapted to provide one or more specialized information services to the service provider  106 . 
         [0051]    The public switched telephone network (PSTN)  110  may be coupled to the MSC  118   a . Accordingly, the MSC  118   a  may be adapted to switch calls originating from within the PSTN  110  to one or more mobile terminals serviced by the wireless service provider  104 . Similarly, the MSC  118   a  may be adapted to switch calls originating from mobile terminals serviced by the wireless service provider  104  to one or more telephones serviced by the PSTN  110 . 
         [0052]    The information content source  114  may comprise a data carousel. In this regard, the information content source  114  may be adapted to provide various information services, which may comprise online data including audio, video and data content. The information content source  114  may also comprise file download, and software download capabilities. In instances where a mobile terminal fails to acquire requested information from the information content source  114  or the requested information is unavailable, then the mobile terminal may acquire the requested information via, for example, a B-UMTS from the portal  108 . The request may be initiated through an uplink cellular communication path. 
         [0053]    The mobile terminals (MTs)  116   a  and  116   b  may comprise suitable logic, circuitry and/or code that may be adapted to handle the processing of uplink and downlink cellular channels for various access technologies and broadcast VHF/UHF technologies. In an exemplary embodiment of the invention, the mobile terminals  116   a ,  116   b  may be adapted to utilize one or more cellular access technologies such as GSM, GPRS, EDGE, CDMA, WCDMA, CDMA2000, HSDPA and MBMS (B-UMTS). The mobile terminal may also be adapted to receive and process VHF/UHF broadcast signals in the VHF/UHF bands. For example, a mobile terminal may be adapted to receive and process DVB-H signals. A mobile terminal may be adapted to request information via a first cellular service and in response, receive corresponding information via a VHF/UHF broadcast service. A mobile terminal may also be adapted to request information from a service provider via a cellular service and in response, receive corresponding information via a data service, which is provided via the cellular service. The mobile terminals may also be adapted to receive VHF/UHF broadcast information from either the base stations  104   a ,  104   b ,  104   c ,  104   d  or the VHF/UHF broadcast antennas  112   a  and  112   b . In instances where a mobile terminal receives broadcast information from any of the base stations  104   a ,  104   b ,  104   c , or  104   d  via a downlink MBMS communication channel, then the mobile terminal may communicate corresponding uplink information via an uplink cellular communication channel. 
         [0054]    In one embodiment of the invention, a mobile terminal may be adapted to utilize a plurality of broadcast integrated circuits for receiving and processing VHF/UHF channels, and a plurality of cellular integrated circuits for receiving and processing cellular or PCS channels. In this regard, the plurality of cellular integrated circuits may be adapted to handle different cellular access technologies. For example, at least one of the cellular integrated circuits may be adapted to handle GSM, and at least one of the cellular integrated circuits may be adapted to handle WCDMA. For broadcast channels, each of the plurality of broadcast integrated circuits may be adapted to handle at least one VHF/UHF channel. 
         [0055]    In another embodiment of the invention, a mobile terminal may be adapted to utilize a single broadcast integrated circuit for receiving and processing VHF/UHF channels, and a single cellular integrated circuit for receiving and processing cellular or PCS channels. In this regard, the single cellular integrated circuit may be adapted to handle different cellular access technologies. For example, at least one of the cellular integrated circuit may be adapted to handle GSM, and at least one of the cellular integrated circuits may be adapted to handle WCDMA. For broadcast channels, the single broadcast integrated circuit may be adapted to handle at least one VHF/UHF channel. Each of the mobile terminals may comprise a single memory interface that may be adapted to handle processing of the broadcast communication information and processing of cellular communication information. In this regard, an uplink cellular communication path may be utilized to facilitate receiving of broadcast information via a broadcast communication path. 
         [0056]    In another embodiment of the invention, a mobile terminal may be adapted to utilize a single integrated circuit for receiving and processing broadcast VHF/UHF channels, and for receiving and processing cellular or PCS channels. In this regard, the single broadcast and cellular integrated circuit may be adapted to handle different cellular access technologies. For example, the single integrated circuit may comprise a plurality of modules each of which may be adapted to receive and process a particular cellular access technology or a VHF/UHF broadcast channel. Accordingly, a first module may be adapted to handle GSM, a second module may be adapted to handle WCDMA, and a third module may be adapted to handle at least one VHF/UHF channel. 
         [0057]      FIG. 1   b  is a block diagram of an alternative embodiment of the exemplary system of  FIG. 1   a  for providing integrated services between a cellular network and a digital video broadcast network, in accordance with an embodiment of the invention. Referring to  FIG. 1   b , there is shown terrestrial broadcaster network  102 , wireless service provider network  104 , service provider  106 , portal  108 , public switched telephone network  110 , and mobile terminals (MTs)  116   a  and  116   b . The terrestrial broadcaster network  102  may comprise transmitter (Tx)  102   a , multiplexer (Mux)  102   b , and VHF/UHF broadcast antennas  112   a  and  112   b . Although VHF/UHF broadcast antenna  112   b  is illustrated separately from the terrestrial broadcast network  102 , it may still be part of the terrestrial broadcast network  102 . The wireless service provider network  104  may comprise mobile switching center (MSC)  118   a , and a plurality of cellular base stations  104   a ,  104   b ,  104   c , and  104   d.    
         [0058]    The system of  FIG. 1   b  is somewhat similar to the  FIG. 1   a  with the exception that  FIG. 1   b  has the content source  114  located external to the terrestrial broadcast network  102 . The content source  114 , which may also be referred to as a data carousel, may comprise audio, data and video content. At least a portion of the audio, data and/or video content stored in the content source  114  may be linked so that if information cannot be retrieved from the content source  114 , then it may be received from the portal  108 . In the system of  FIG. 1   b , a provider other than the terrestrial broadcaster  102  may manage the content source  114 . Notwithstanding, the audio, video and/or data from the content source  114  may still be multiplexed by the multiplexer  102   b  in the terrestrial broadcast network  114 . 
         [0059]      FIG. 1   c  is a block diagram of an alternative embodiment of the exemplary system of  FIG. 1   a  for providing integrated services between a cellular network and a digital video broadcast network, in accordance with an embodiment of the invention. Referring to  FIG. 1   c , there is shown terrestrial broadcaster network  102 , wireless service provider network  104 , portal  108 , public switched telephone network  110 , and mobile terminals (MTs)  116   a  and  116   b . The terrestrial broadcaster network  102  may comprise transmitter (Tx)  102   a , multiplexer (Mux)  102   b , service provider  106 , and VHF/UHF broadcast antennas  112   a  and  112   b . The wireless service provider network  104  may comprise mobile switching center (MSC)  118   a , and a plurality of cellular base stations  104   a ,  104   b ,  104   c , and  104   d.    
         [0060]    The system of  FIG. 1   c  is somewhat similar to the  FIG. 1   a  with the exception that  FIG. 1   b  has the service provider  106  co-located with the terrestrial broadcast network  102 . In this regard, the terrestrial broadcast network  102  may control the functions of the service provider  106 . Since the terrestrial broadcast network  102  controls the functions of the service provider, the broadcast services may be more efficiently provided to the mobile terminals via the MBMS path provided by the wireless service provider  104  and/or the VHF/UHF broadcast downlink path provided by the terrestrial broadcaster network  102 . Hence, instead of having to send information to an externally located service provider, the integrated control and logic services provided the terrestrial broadcaster network  102  and service provider  106  may instantly make decisions of how best to handle information for a mobile terminal. 
         [0061]      FIG. 1   d  is a block diagram of an alternative embodiment of the exemplary system of  FIG. 1   a  for providing integrated services between a cellular network and a digital video broadcast network, in accordance with an embodiment of the invention. Referring to  FIG. 1   d , there is shown terrestrial broadcaster network  102 , wireless service provider network  104 , portal  108 , public switched telephone network  110 , and mobile terminals (MTs)  116   a  and  116   b . The terrestrial broadcaster network  102  may comprise transmitter (Tx)  102   a , multiplexer (Mux)  102   b , and VHF/UHF broadcast antennas  112   a  and  112   b .

         [0062]    The system of  FIG. 1   d  is somewhat similar to the  FIG. 1   a  with the exception that  FIG. 1   b  has the service provider  106  co-located with the wireless service provider network  104 . In this regard, the wireless service provider network  104  may control the functions of the service provider  106 . Since the wireless service provider network  104  controls the functions of the service provider  106 , the broadcast services may be more efficiently provided to the mobile terminals via the MBMS path provided by the wireless service provider  104  and/or the VHF/UHF broadcast downlink path provided by the terrestrial broadcaster network  102 . Hence, instead of having to send information to an externally located service provider  106  as illustrated in  FIG. 1   a , the integrated control and logic services provided the service provider  106  may instantly make decisions of how best to handle communication of information for a mobile terminal. 
         [0063]    In another embodiment of the invention, since many of the services provided by the service provider  106  may already be integrated into the wireless service provider&#39;s  104  infrastructure, then the complexity of the service provider functions may be significantly reduced. For example, the wireless service provider  104 , the latter of which already has the pertinent infrastructure in place, may now handle operation administration maintenance and provisioning (OAM&amp;P) functions, which may be required by the service provider  106 . Since the uplink capabilities are inherent in only the wireless service provider network  104 , and the service provider function are also located within the service provider network  106 , the uplink capabilities for the mobile stations  116   a ,  116   b  may be more efficiently managed from within the wireless service provider network  104 . 
         [0064]      FIG. 1   e  is a high-level block diagram of exemplary DVB-H receiver circuitry in a mobile terminal, which may be utilized in connection with an embodiment of the invention. Referring to  FIG. 1   e , there is shown a mobile terminal  130 . The mobile terminal  130  may comprise a DVB-H demodulator  132  and processing circuitry block  142 . The DVB-H demodulator block  132  may comprise a DVB-T demodulator  134 , time slicing block  138 , and MPE-FEC block  140 . 
         [0065]    The DVB-T demodulator  134  may comprise suitable circuitry, logic and/or code that may be adapted to demodulate a terrestrial DVB signal. In this regard, the DVB-T demodulator  134  may be adapted to downconvert a received DVB-T signal to a suitable bit rate that may be handled by the mobile terminal  130 . The DVB-T demodulator may be adapted to handle 2k, 4k and/or 8k modes. 
         [0066]    The time slicing block  138  may comprise suitable circuitry, logic and/or code that may be adapted to minimize power consumption in the mobile terminal  130 , particularly in the DVB-T demodulator  134 . In general, time slicing reduces average power consumption in the mobile terminal by sending data in bursts via much higher instantaneous bit rates. In order to inform the DVB-T demodulator  134  when a next burst is going to be sent, a delta indicating the start of the next burst is transmitted within a current burst. During transmission, no data for an elementary stream (ES) is transmitted so as to allow other elementary streams to optimally share the bandwidth. Since the DVB-T demodulator  134  knows when the next burst will be received, the DVB-T demodulator  134  may enter a power saving mode between bursts in order to consume less power. Reference  144  indicates a control mechanism that handles the DVB-T demodulator  134  power via the time slicing block  138 . The DVB-T demodulator  134  may also be adapted to utilize time slicing to monitor different transport streams from different channels. For example, the DVB-T demodulator  134  may utilize time slicing to monitor neighboring channels between bursts to optimize handover. 
         [0067]    The MPE-FEC block  140  may comprise suitable circuitry, logic and/or code that may be adapted to provide error correction during decoding. On the encoding side, MPE-FEC encoding provides improved carrier to noise ratio (C/N), improved Doppler performance, and improved tolerance to interference resulting from impulse noise. During decoding, the MPE-FEC block  140  may be adapted to determine parity information from previously MPE-FEC encoded datagrams. As a result, during decoding, the MPE-FEC block  140  may generate datagrams that are error-free even in instances when received channel conditions are poor. The processing circuitry block  142  may comprise suitable processor, circuitry, logic and/or code that may be adapted to process IP datagrams generated from an output of the MPE-FEC block  140 . The processing circuitry block  142  may also be adapted to process transport stream packets from the DVB-T demodulator  134 . 
         [0068]    In operation, the DVB-T demodulator  134  may be adapted to receive an input DVB-T RF signal, demodulate the received input DVB-T RF signal so as to generate data at a much lower bit rate. In this regard, the DVB-T demodulator  134  recovers MPEG-2 transport stream (TS) packets from the input DVB-T RF signal. The MPE-FEC block  140  may then correct any error that may be located in the data and the resulting IP datagrams may be sent to the processing circuitry block  142  for processing. Transport stream packets from the DVB-T demodulator  134  may also be communicated to the processing circuitry block  142  for processing.

         [0071]    The multiplexer  156  may comprise suitable logic circuitry and/or code that may be adapted to handle multiplexing of IP encapsulated DVB-H data and service data. The plurality of service data collectively referenced as  160  may comprise MPEG-2 formatted data, which may comprise for example, audio, video and/or data. 
         [0072]    The DVB-T modulator  162  may comprise suitable logic circuitry and/or code that may be adapted to generate an output RF signal from the transmitter block  150 . 
         [0073]    The DVB-H demodulator block  166  associated with the receiver block  151  is similar to the DVB-H demodulator block  132  of  FIG. 1   e . The DVB-H decapsulation block  168  may comprise MPE block  168   a , MPE-FEC block  168   b  and time slicing block  168   c .

An output of the low pass filter  220  may be communicated to the analog-digital-converter for processing. 
         [0081]    The analog-to-digital converter (A/D)  222  may comprise suitable logic, circuitry and/or code that may be adapted to convert the analog signal generated from the output of the low pass filter  220  to a digital signal. The analog-to-digital converter  222  may generate a sampled digital representation of the low pass filtered signal that may be communicated to the baseband-processing block  224  for processing. The baseband processing block  224  may comprise suitable logic, circuitry and/or code that may be adapted to process digital baseband signals received form an output of the A/D  222 . Although the A/D  222  is illustrated as part of the RFE circuit  210 , the invention may not be so limited. Accordingly, the A/D  222  may be integrated as part of the baseband processing block  224 . In operation, the RFE circuit  210  is adapted to receive RF signals via antenna  211  and convert the received RF signals to a sampled digital representation, which may be communicated to the baseband processing block  224  for processing. 
         [0082]      FIG. 2   c  is a high-level block diagram illustrating an exemplary configuration for a RFIC and a base band processing circuit, in accordance with an embodiment of the invention. Referring to  FIG. 2   c , there is shown RFIC  230  and baseband circuitry  232 . The RFIC  230  comprises a plurality of RF processing circuits  230   a ,  230   b ,  230   c  and  230   n . The RF processing circuits  230   a ,  230   b ,  230   c  and  230   n  may be integrated in a single integrated circuit (IC) or chip. The baseband processing circuitry  232  comprises a plurality of baseband processing circuits  232   a ,  232   b ,  232   c  and  232   n . The baseband processing circuits  232   a ,  232   b ,  232   c  and  232   n  may be integrated into a single integrated circuit (IC) or chip. 
         [0083]    In operation, each of the RF processing circuits in the RFIC  230  may be adapted to process a single channel. For example, each of the RF processing circuits  230   a ,  230   b  and  230   c  may be adapted to process separate cellular channel, namely, channel  1 , channel  2  and channel (n−1), respectively. The RF processing circuit  230   n  many be adapted to process a VHF/UHF broadcast channel n. 
         [0084]    Each of the baseband processing circuits in the baseband processing circuitry  230  may be adapted to process a single channel. For example, each of the baseband processing circuits  232   a ,  232   b  and  232   c  may be adapted to process separate cellular channels, namely, channel  1 , channel  2  and channel (n−1), respectively. The RF processing circuit  232   n  may be adapted to process a VHF/UHF broadcast channel n. Use of a single RFIC and a single baseband processing integrated circuit saves on the size of the processing circuitry, which may significantly reduce cost. 
         [0085]      FIG. 2   d  is a flowchart illustrating exemplary steps that may be utilized in connection with an embodiment of the invention. Referring to  FIG. 2   d , in step  262 , the a mobile terminal may request cellular information via a cellular communication path. In step  264 , the request for information may be processed. In step  266 , in response to the request, it may be determined whether to deliver information via a cellular broadcast path or a VHF/UHF broadcast path. In step  268 , based on the determination in step  266 , the requested information may be delivered to the mobile terminal via the cellular broadcast path. In step  270 , based on the determination in step  266 , the requested information may be delivered to the mobile terminal via the VHF/UHF broadcast path. 
         [0086]      FIG. 2   e  is a diagram of an exemplary mobile terminal that may be utilized for communicating information via a plurality of different networks, accordance with an embodiment of the invention. Referring to  FIG. 2   e , there is shown a mobile terminal  270  comprising processing circuitry  272 . The processing circuitry  272  may comprise statistic measurement circuitry  274 . 
         [0087]    In operation, the mobile terminal  270  may be adapted to receive cellular information via a cellular information path and VHF/UHF broadcast information via a VHF/UHF broadcast information path. The mobile terminal  270  may switch between processing the broadcast information received information received via the VHF/UHF broadcast communication path and the cellular information received via the cellular communication path. The switching may be based on a measured broadcast signal statistic associated with a signal bearing the broadcast information and a measured cellular signal statistic associated with a signal bearing the cellular information. The measured broadcast signal statistic and/or the measured cellular signal statistic may comprise exemplary information such as received signal strength indication (RSSI), SNR, signal quality or other channel related information. The quality of service will be enhanced by measuring SNR and RSSI to determine if the MBMS channel or the DVB channel are the best to broadcast data over. Also, another measure that may be used is determining the system capacity of the cellular network and the DVB network to determine the best broadcasting network.
