## Background
BACKGROUND
Exemplary embodiments relate generally to digital television, and more particularly to providing broadband television services (BTS).
Internet protocol television (IPTV) service is a digital television delivery service, where the digital television signal is delivered to users via a computer network infrastructure using the Internet Protocol. Typically, IPTV services are bundled with additional Internet services, such as Internet web access and voice over Internet protocol (VoIP). Subscribers and users of subscriber devices receive IPTV services via a set top box, or IPTV receiver that is connected to or incorporated in the same device as a television or display device for the reception of a digital signal. Used in conjunction with an IP-based platform, the set top box allows for a subscriber or other user to access IPTV services and any additional services that are integrated within the IPTV service.
Typically, additional network hardware (e.g., video ready access devices or “VRADS”) must be installed to support IPTV. This additional hardware is often costly and manpower is required to perform the installations. Further, having to install additional hardware may impact the ability of an IPTV service provider to quickly gain entry into the IPTV marketplace and to keep up with the demand for IPTV services. In order to alleviate these cost and timing issues, it would be advantageous to be able to provide IPTV services by utilizing existing network infrastructures.

The scenario depicted in FIG. 4 requires the service location 408 to interface with two service providers.
FIG. 5 illustrates a block diagram of a system that provides broadband Internet service, IPTV service and telephone service to a service location 506 from a single telephone service provider 514. The telephone 116, a modem 502 (connected to the computer 112) and an IPTV receiver 509 (connected to the television 110) are in communication with a signal splitter 508. In an exemplary embodiment, the modem 502 is an ADSL modem. The IPTV receiver 509 receives IP video packets and assembles them into video signals that can be displayed on the television 110. The signal splitter 508 depicted in FIG. 5 is in communication with a DSLAM 510 (e.g., via a copper twisted pair) for providing access to a telephone network 516 via the telephone service provider 514. The telephone signals are typically passed through the DSLAM 510 to the telephone service provider 514.
The DSLAM 510 in FIG. 5 is also in communication with the Internet 204 (e.g., via an internet service provider or “ISP”) and a video ready access device (VRAD) 512. The VRAD 512 is utilized to provide IPTV services to the service location 506. A drawback to the scenario depicted in FIG. 5 is that it requires a relatively costly VRAD device to be installed within a specified distance of the service location 506. Another drawback is that it requires the use of the signal splitter 508 at the service location 506 to direct the signals to the correct device (telephone 116, computer 112 or IPTV receiver 509).
FIG. 6 illustrates a system for providing BTS using a DSL network, this system may be implemented by exemplary embodiments. As used herein, the term “DSL network” refers to a network that does not include a VRAD. The system depicted in FIG. 6 provides BTS by utilizing an existing broadband service, thus eliminating the need for a VRAD. The system depicted in FIG. 6 provides broadband Internet service, BTS service and telephone service to a service location 602 from a single telephone service provider 606 via a DSLAM 604. The components located at the service location 602 include the telephone 116, modem 618 (connected to the computer 112) and a BTS receiver 616 (connected to the television 110). The connection between the modem 618 and the DSLAM 604 may be via a copper twisted pair, via fiber where available, or via any other type of physical connection. The system depicted in FIG. 6 allows for a single service provider, the telephone service provider 606, to provide all telephone, television and Internet services via a single connection to a DSLAM 604.
In the embodiment depicted in FIG. 6, the modem 618 is the same DSL modem 210 described previously with respect to FIG. 2. The BTS receiver 616 is modified to accept streaming video for conversion into a format utilized by the television 110. In addition, the BTS receiver 616 communicates to the existing DSL modem 618 and it may also provide other functionality as described herein.
The DSLAM 604 depicted in FIG. 6 allows the telephone 116 to communicate with the telephone service provider 606 and with a telephone network 608. In addition, the DSLAM 604 provides a connection from the computer 112 to the Internet 204 via an ISP network 610. Thus, the configuration of the hardware related to the telephone and Internet services at the service location 602 depicted in FIG. 6 is similar to the configuration depicted in FIG. 2.
The links depicted in FIG. 6 to provide BTS services include: the television 110, the BTS receiver 616, the modem 618, and the DSLAM 604 which communicates with the internet service provider (ISP) network 610 to provide secure access to the Internet addresses (for both local television networks 612 and other television networks). In this manner both national and local television networks may be provided to the service location 602 via exemplary embodiments. The ISP network 610 is in communication with one or more Internet addresses 614 that provide live streaming video. One Internet address may contain a national sports network broadcast, another a movie network broadcast, and another local a news network broadcast.
The BTS receiver 616 is initialized (e.g., at a factory or at a customer site) to correlate particular Internet addresses 614 with particular channel selections on the television 110. For example, channel 5 on the television may correspond to the Internet address for a national news network and channel 6 may correspond to the Internet address for a local sports channel. When the television viewer selects channel 5, IP video packets containing streaming video of the current broadcast from the corresponding Internet address will be sent to the BTS receiver 616 for assembly into video signals that can be displayed on the television 110. Thus, whatever is currently playing on the channel will be sent to the BTS receiver 616. Exemplary embodiments allow BTS to simulate the current method of television broadcast, where signals for a channel are being sent continuously over the airwaves and when the television is tuned into the channel the television plays whatever is currently being broadcasted over the airwaves for that channel.
The BTS receiver 616 may be initialized at the factory to correlate particular Internet addresses to particular television channels. In exemplary embodiments, portions or all of the initialization may be changed at the service location by a service technician or remotely via the Internet. Any number of Internet addresses may contain streaming video and be correlated to particular television channels. In alternate exemplary embodiments, the Internet address contains streaming video from a closed circuit television to provide, for example, security monitoring. In other alternate embodiments, the television 110 may be utilized as a computer to access the Internet 204.
In exemplary embodiments video compression techniques and compression/decompression (CODEC) algorithms for reducing and/or eliminating lag and re-buffering on slower speed broadband services are utilized. In exemplary embodiments security is provided to prevent unauthorized users from accessing the streaming video at the Internet addresses.
The BTS receiver 616 in FIG. 6 may be utilized for service locations that already have a connection to a DSLAM, such as the DSLAM 604, and a modem, such as the modem 618, for communicating with the Internet 204. This allows ease of upgrade to existing customers because the new functionality is located in the BTS receiver 616 which is connected to the existing modem 618.
FIG. 7 depicts a configuration of local networks 612 that may be implemented by exemplary embodiments. In general, a different list of local networks is provided depending on the geographic location of the service location. As depicted in FIG. 7, the list of local television networks for Birmingham, Ala. 702 include channels 33/40, 6, 42, etc., while the list of local networks for Huntsville, Ala. 704 include channels 31, 19, 48, 54, etc. Thus, in this example, a service location in Birmingham, Ala. will receive a different set of local network stations than a service location in Huntsville, Ala. In exemplary embodiments, the set of local networks is fixed based on the geographic location of the service location. In alternate exemplary embodiments, a customer at a service location may select one or more groupings of local networks and be provided local news from a geographic location that is different than the service location.
