Bell TV by hi joiney
(4640, ‘History br ExpressVu was conceived in 1994 at the time of American DSS systems launch as a consortium of Ontario based Tee Comm Electronics Canadian Satellite Communications Cancom Vancouver based Western International Communications WIC and Bell Canada BCE with a projected startup date of late 1995 High technology development costs and delays placed Tee Comm in a severe financial position prompting the remaining partners to pull out in 1996 Instead U S satellite TV provider Echostar Dish Network was chosen to provide the receivers and uplink equipment The Hughes DirecTV system had already been optioned to Power Broadcasting in Canada it has since been withdrawn Tee Comm on its own managed to launch the first DBS service in Canada AlphaStar in early 1997 however in a matter of months the company went bankrupt and the service was discontinued leaving thousands of consumers with useless receivers ExpressVu launched service in September 1997 initially as Dish Network Canada followed by ExpressVu Dish Network in both cases using the Echostar logo However by 2000 Bell took over full ownership of ExpressVu br Bell rebranded the names of its services as of August 2008 The ExpressVu name and the beavers used in the advertising campaign were retired along with the Sympatico internet name ExpressVu became Bell TV Plans have been shelved for any additional ExpressVu satellite expenditures assuming pending FCC and Industry Canada approval for Dish Network to use all 32 transponders on Nimiq 5 As a result of this SES has announced that they will not be replacing the ill fated AMC 14 now that Dish Network has cut this deal with Telesat amp BCE for Nimiq 5 usage br Satellites br Bell TV broadcasts from four geostationary satellites Nimiq 1 2 3 and 4iR Nimiq 4iR is temporary and is being replaced by Nimiq 4 nimiq 4 has replaced nimiq 2 site is 82 05w All follow an equatorial path giving coverage to most of Canada Nimiq is an Inuktitut word for that which unifies and was chosen from a nationwide naming contest in 1998 The four satellites are owned and operated by Telesat Canada ExpressVu s uplink site is located in North York which is in the Toronto area br Nimiq 1 was launched on May 20 1999 and contains 32 Ku band transponders at 91 W From the time of service launch in 1997 to the switch to Nimiq in 1999 ExpressVu used the already crowded Anik E2 Nimiq 2 launched on December 29 2002 also includes 32 K band transponders Nimiq 2 provides HDTV international programming and all newly released channels It occupies the 82 W slot Nimiq 3 went online on August 23 2004 Originally called DirecTV3 it is an old DirecTV satellite moved to a new orbital slot near Nimiq 1 to offload some of the transmitting work from the original satellite In February 2006 Nimiq 3 was moved behind Nimiq 2 to support it while another satellite Nimiq 4i formerly DirecTV2 took Nimiq 3 s spot behind Nimiq 1 Nimiq 4i was replaced with Nimiq 4iR as it ran out of fuel on April 28 2007 and was de orbited Both Nimiq 3 and Nimiq 4iR feature 16 Ku band transponders Nimiq 4 was launched by a Proton rocket which lifted off on September 19 2008 at 21 48 UTC br Each satellite typically has 32 divisions of signal ie transponders A transponder usually has enough bandwidth to broadcast approximately 10 channels Because HDTV requires more bandwidth some transponders on Nimiq 2 will typically broadcast only 4 5 channels LyngSat provides a listing of channels on Nimiq 1 and Nimiq 2 broken down by transponder br Satellite TV equipment br Bell TV currently provides 20 inch 50 160 cm dishes to its customers Canadians living in the territories and certain parts of British Columbia amp Newfoundland require larger dishes between 60 and 120 160 cm these are used to compensate for the weaker satellite signal available to these regions The 20 dish supports two LNBs The size of the dish was increased from 18 to 20 inches in late 2001 to accommodate a second LNB to acquire signal from Nimiq 2 BEV 82 satellite At the end of the dish s arm a Y adapter is found which holds both LNBs The BEV 91 LNB is in the center of the dish while the BEV 82 LNB is offset to the left Rotating the dish i e modifying the skew angle changes the position of the 82 LNB while maintaining position for BEV 91 A switchbox typically an SW21 or SW44 is used to merge both satellite signals into receivers br Bell TV Satellite Receivers are manufactured for Echostar by Sanmina SCI in Guadalajara Mexico A multitude of receivers are currently provided all with internal smartcards br The 4100 is Bell TV s current basic receiver It is half the size of all previous basic receivers and provides a coaxial and RCA output New to the basic model is an optical output for 5 1 surround sound purposes br The 5900 is a single tuner PVR with the capacity to record up to 80 hours of programming It offers a coaxial output two sets of RCAs S Video and an optical output It can respond to both IR and UHF signals The Hard Drive has a one hour buffer intended for rewinding and pausing purposes meaning that you can rewind a channel back up to an hour or keep an event paused for that same duration before it goes back to PLAY mode Pressing VIEW on the remote will always bring the receiver back into LIVE mode i e the user will see what is currently being broadcast br The 6131 is a single tuner HDTV receiver will allows decoding of MPEG 2 and MPEG 4 signals Bell TV is planning on using MPEG 4 starting 2010 for HD channel transmission in order to save bandwidth It offers both a HDMI and component connectors for HDTV purposes The 6131 also has a USB 2 0 port which allows an external hard drive to be attached to the unit giving the 6131 PVR functionality A previous version of the 6131 the 6141 sold for a period in 2007 2008 it s main difference is the inclusion of a OTA tuner br The 9241 is Bell TV s latest receiver It is a Dual Tuner Pvr Receiver with HDTV capabilities and can record either 200 hours of standard definition or 30 hours of HDTV It is similar to the 9200 9242 but is only able to output to play content to one TV and has no OTA tuner The 9241 is able to receive MPEG 4 in addition to MPEG 2 signals which Bell TV is rumoured to start using starting 2011 for HD channel transmission in order to save bandwidth br The 9242 is Bell TV s most powerful receiver although it have stopped being produced since the release of the 9241 in 2008 It is a dual tuner PVR receiver with HDTV capabilities on output 1 and SD content on output 2 and can record either 200 hours of standard definition or 30 hours of HDTV It is similar to the 9200 but is able to receive MPEG 4 in addition to MPEG 2 signals which Bell TV is rumoured to start using starting 2011 for HD channel transmission in order to save bandwidth A firmware upgrade in August 2008 allowed owners to attach an external hard drive for archiving of recorded content br Current HDTV receivers support resolutions of 480i 480p 1080i and 720p Although not supported by Bell TV a component or S Video connection to a non HD television set at 480i will actually give picture but only 1080i and 720p will actually yield HD quality The star and PAGE UP buttons of the remote allow the client to change the aspect ratio of their screen enabling them to manipulate the image with a zoom partial zoom stretch and with the use of gray bars Grey bars seem to be used on 4 3 images to prevent burn in br To authorize programming a portable smartcard is used for older receivers like the 1000 2700 2800 3700 3000 3500 4000 4500 4700 3100 5100 5800 5900 and the 6000 Newer receivers incorporate smartchips which are permanently installed inside the receiver In some cases Bell TV has switched back to using standard smartcards for the 6100 and 9200 receivers In February 2008 Bell TV announced that it will start a smartcard swap the second in three years involving all its receivers with the exception of the 6141 9241 models This is required due to the massive pirating of ExpressVu signals due the hacked Nagra 2 encryption with was previously implemented with a previous smartcard swap in 2005 to end piracy Although previous hacked in earlier versions Bell TV has upgraded to Nagravision 3 as the new encryption standard to prevent un authorized access to pay TV channels Currently the Nagravision 3 protocol has been holding up The only means to view Bell TV illegally is through IKS Internet Key Sharing devices which include NFusion FTA and the Slinger Both devices are not hacks but only means of a workaround Bell TV is currently working towards shutting down these types of devices The Nagravision 3 protocol is currently holding up as no known hacks exist br In 2009 Bell 6000 receivers owners received letters in the mail that state they must swap to a 6141 or face losing programming as Bell TV is currently going to be using MPEG 2 with 8PSK the 6000 does support the use of 8PSK with an add in module But Bell TV decided not send out these as the 6000 is old and most customers will be wanting to upgrade to a 6141 which can have a hard disk drive added to it to be used as a PVR and the guide for programming information is also updated and stores more info in its database then the 6000 br Many types of remotes have been released over the years Models 1000 and 2700 came out with very basic infrared IR remotes that could be used only to control the receivers themselves and would operate on all 16 remote addresses Replacement remotes then came with universal functions allowing users to control the power and volume of their televisions along with VCRs and sound system receivers these remotes can only operate on a single address at a time Models equipped with a UHF antenna can respond to UHF remotes these remotes use radio frequencies rather than IR signals to control the receivers UHF signals can reach up to 30 meters depending on the restrictions of building materials All UHF compatible receivers can simultaneously respond to IR signals except for model 4500 For this model modification directions exist on the internet to add IR receiving capability in order for the receiver to respond to programmable universal remotes Remote 2 of the 3200 5200 9200 and the remote for model 6100 are based on Uhf Pro UHF Pro remotes are strictly compatible with the receivers they are provided with and do not function on regular UHF compatible receivers Additionally UHF Pro remotes can only communicate with UHF frequencies and cannot control receivers via IR To prevent interference with other UHF remotes in proximity clients should change their remote addresses All secondary remotes for dual tuners may also be converted to remote 1 by flipping the plastic bottom of the remote This also switches its transmission mode from UHF Pro to regular UHF and IR similar to how a 5900 remote operates br Service policies br Residential accounts are limited to a maximum of six 6 receivers per account but each of them can be a dual Tuner Receiver and can serve 12 TVs Having receivers on one account located in different locations is contrary to the Bell TV Residential and Commercial Agreements but it is certainly not illegal the worst that can happen is cancellation of service This is referred to as Account Stacking br Account Stacking is discussed in detail in CRTC Public Notice 2006 133 and 2006 134 where ExpressVu notes that there is no requirement whatsoever in the Regulations that prohibits a BDU broadcast distribution undertaking from providing service at more than one location via a single account br Most customers have the misconception that the phone line is used for software downloads and programming changes The phone line connection is used strictly for sending information and is solely used for ordering Pay per view and to verify the client s location Clients who do have multiple receivers and who do not connect them to phone lines can expect the shutdown of all their receivers except for one by the Multiple Receiver Verification Process department MRVP The MRVP department will call clients with multiple receivers and ask for the location ID number contained within the receiver s system information the location ID number changes on a regular basis If the client is unable to confirm the location ID of any receiver the MRVP department may at its discretion disable the unverified equipment br Previously the Nimiq 1 signal was available to most of North America However the launch of Nimiq 3 cut off access to most transponders in southern United states citation needed Bell TV made this modification to 1 boost signal on most transponders of Nimiq 1 to combat rain fade and 2 prevent American residents and mostly snowbirds in Florida from using its service citation needed The use of Bell TV s service in the United States is not illegal however it remains a contentious issue br Bell TV due to increased competition now provides technical support 24 7 however it will only support its products Customer service and technical support staff work within the same department and are trained on a tier system regarding their technical support authority Every representative spoken with will have at least the basic knowledge of how to troubleshoot connections between the Satellite Receiver and the television including multiple electronic piggyback 160 when the receiver is connected through a VCR DVD player stereo system or other device However if a loss of connection or other technical issue stems to a device other than the receiver itself under no circumstances will they support TV’)
