It may be a [[pay TV]] service broadcast on [[mobile phone]] networks or received [[free-to-air]] via [[terrestrial television]] stations from either regular broadcast or a special mobile TV transmission format. Some mobile televisions can also [[download]] television shows from the internet, including recorded [[TV program]]s and [[podcast]]s which are downloaded and stored on the mobile device for later viewing. The first pocket sized mobile television was sold to the public by [[Clive Sinclair]] in January 1977. It was called the Microvision or the [[MTV-1]]. It had a 2in [[Cathode ray tube|CRT]] screen and was also the first television which could pick up signals in various countries.<ref name="Clive's achievements">[http://www.sinclair-research.co.uk/about-srl.php Clive's achievements] [[Sinclair Research]]</ref><ref name="Video and TV gear">[http://www.retrothing.com/video_tv/index.html Video and TV gear], [[Retrothing.com]]</ref> ==History== [[Image:MTV-1.jpg|thumb|300px|The [[MTV-1]] was the world's first pocket sized television.

It measured 102x159x41mm and was sold for less than [[Pounds sterling|£]]100 in the [[United Kingdom|UK]] and for around [[US Dollar|$]]400 in the [[United States|US]]. The project took over ten years to develop and was funded by around £1.6 million in British Government grants.<ref name="Clive's achievements"/><ref name="Video and TV gear"/> Mobile TV is one of the features provided by many [[3G]] phones. In 2005, [[South Korea]] became the first country in the world to have mobile TV when it started satellite DMB ([[S-DMB]]) and terrestrial DMB ([[T-DMB]]) services on May 1 and December 1, respectively. Today, South Korea and [[Japan]] are at the forefront of this developing sector.<ref>NYTimes.com via Yahoo!

The Panasonic measures approximately 6.25 x 3.90 x 1.85&nbsp;inches. I purchased the set new in 1970. The Sinclair MTV-1 was introduced in 1977 and measures 4 x 6 1/4 x 1 5/8&nbsp;inches or 102x159x41mm. The Sony FD-210 was the first flat CRT portable television in production. (see Vintage Micro Television http://www.visions4.net/journal/time-line/ ) == Overview == {{Expert-subject|Telecommunications|section|date=March 2009}} Mobile TV is a service which allows cell phone owners to watch television on their phones from a service provider. Television data can be obtained either through an existing cellular network or a [[wikt:proprietary|propriety]] network. In South Korea, mobile TV is largely divided into satellite DMB ([[S-DMB]]) and terrestrial DMB ([[T-DMB]]). Although S-DMB initially had more content, T-DMB has gained much wider popularity because it is free and included as a feature in most mobile handsets sold in the country today. Mobile TV is also available for [[consumer]]s in [[India]]. BSNL introduced this feature for its eastern and north-eastern regions of India. In 2007, it also launched a mobile TV application called "isee". Today, isee is available not only in the four BSNL zones but also to other networks across India (except Reliance and TATA Indicom CDMA services). An individual using a streaming-enabled handset can download or access the [[Wireless Application Protocol|WAP]] version of this application on his/her mobile by sending a simple sms "isee" to 57575 or log on to http://www.isee.co.in for further information. ==Challenges== * '''Device Manufacturer's challenges''' 1. Power consumption: Battery technology for mobile portable devices may be stuck in a race condition. Improved battery life can be used up by the upgraded mobile content and enhanced functions. However, [[dashtop mobile]] devices can also be powered by a 12-volt vehicle battery, however vehicle batteries are not a sustainable source of power for mobile devices. 2. Memory: To support the high buffer requirements of mobile TV. Current memory capabilities available will not be suited for long hours of mobile TV viewing. Furthermore, potential future applications like [[peer-to-peer video sharing]] in mobile phones and consumer broadcasting would definitely add to the increasing memory requirements. The existing P2P algorithms won't be enough for mobile devices, necessitating the advent of [[mobile P2P]] algorithms. There is one start-up technology that claims [[patent]]ability on its mobile P2P, but has not drawn attention from device manufacturers yet. 3. [[User interface]] design: A large number of mobile phones do not support mobile TV; users have to purchase new handsets with improved LCD display and user interface that support mobile TV. This new design has to appeal to the end-users and increase the clarity of images without making the handset very bulky. The wider LCD touchscreens will be preferred by end-users and iPhone's popularity in the United States is part of the compelling evidence. 4. Processing power: Device manufacturers should improve the processing power significantly to support a MIPS intensive application like mobile TV. * '''Content Provider's challenges''' The mobile TV industry opens up a new market for the content specifically tailored for mobile TVs. These could include making new [[mobisodes]] –mobile episodes of popular shows which are relatively shorter in length (3 to 5 minutes), modifying the content to suit mobile TV. ==Digital TV== ===North America=== {{Unbalanced|section|date=October 2009}} {{Coat rack|[[Network Neutrality]]|date=October 2009}} Mobile TV and mobile digital radio has been a challenge in [[North America]], in part, because of the decision of the [[U.S.]] [[Federal Communications Commission]] (FCC) to use [[Property|proprietary]] systems instead of the principles of [[network neutrality]]. This sometimes leads to [[vendor lock-in]] by [[mobile phone companies]] and [[manufacturer]]s. {{Citation needed|date=January 2010}} {{Weasel-inline|date=January 2010}} The FCC chose the [[ATSC]] system for [[digital TV]] which, with the choice of [[8VSB]] [[modulation]], makes mobile reception difficult, because it is heavily prone to [[multipath interference]] (which changes rapidly in a mobile reception environment). [[ATSC-M/H]] was developed to allow for mobile reception, riding within each [[TV station]]'s regular [[MPEG transport stream]], and using heavy [[error correction]] to compensate for poor signals, while taking space out of the "bit budget" for each station's other [[digital subchannel]]s and/or [[HDTV]]. In comparison with [[DVB-T]], there is no [[hierarchical modulation]] to allow for [[LDTV]] reception, however, the use of [[MPEG-4]] [[Scalable Video Coding]] coding in ATSC-M/H allows for scalable resolutions and frame rates. {{As of|2009}}, [[chipset]]s for ATSC-M/H were not yet in any [[consumer electronics]] devices, but early products using chipsets by [[LG]] and [[Samsung]] were shown at the 2010 [[CES]] and [[NAB]] Conferences. The FCC also chose [[HD Radio]] which, although it uses COFDM and has reasonable mobile reception, does not have provisions for mobile TV as [[Digital Audio Broadcasting|DAB]]-T has with [[DMB-T]] and is incompatible even with neighboring [[Canada]], where the [[Canadian Radio-television and Telecommunications Commission]] (CRTC) already chose DAB in the [[L band]]. [[Satellite radio]] is also proprietary with no choice made by the FCC regarding the system. [[MediaFLO]], which also uses COFDM, is broadcast on [[UHF]] [[TV channel]] 55, but like satellite TV is [[encrypt]]ed and controlled by [[conditional access]] (provided via the [[cellular network]]). Also, it must be purchased as [[pay TV]] for a limited number of cellphones which must have [[AT&T Mobility]] or [[Verizon Wireless]] phone service. ===Broadcast mobile DTV development=== While MediaFLO uses the TV spectrum and [[MobiTV]] used [[Mobile phone|cell phone]] networks,<ref>{{cite news|url=http://mobitv.com/technology/managed-service-platform|title=mobile tv cell phone networks: |last=Thompson |first=Mark |date=2010-06-03 |work=[[Broadcasting & Cable]] |accessdate=2010-06-03}} {{Dead link|date=October 2010|bot=H3llBot}}</ref> "mobile DTV" (ATSC-M/H) uses the [[digital TV]] spectrum. At the [[National Association of Broadcasters]] (NAB) show in April 2007 in [[Las Vegas metropolitan area|Las Vegas]], the [[ATSC]] and [[8VSB]] methods for delivering mobile DTV were shown. [[A-VSB]] (Advanced VSB), from [[Samsung Group|Samsung]] and [[Rohde & Schwarz]], was shown at the previous year's show. In 2007, [[LG Group|LG]], whose [[Zenith Electronics]] came up with 8VSB, introduced (with [[Harris Corporation|Harris Group]]) its [[MPH (ATSC)|Mobile-Pedestrian-Handheld]] (MPH) system. As the broadcast networks began making their content available online, mobile DTV meant stations would have another way to compete. [[Sinclair Broadcast Group]] tested A-VSB in fall 2006, and its [[KVCW]] and [[KVMY]] were participating in the mobile DTV [[product demonstration]]s at the NAB show. A-VSB had worked in [[bus]]es at the 2007 [[Consumer Electronics Show]]. [[ION Media Networks]] started a test station on channel 38, which was to be used for digital [[LPTV]], to use for a [[single-frequency network]] (SFN). In some areas, more than one [[TV transmitter]] would be needed to cover all areas. Mobile DTV could have been used at that time because it would not affect [[HDTV]] reception. A single standard, however, had to be developed.<ref>{{cite news|url=http://www.broadcastingcable.com/article/108538-NAB_Mobile_DTV_Hits_the_Strip.php|title=NAB: Mobile DTV Hits the Strip|last=Dickson |first=Glen |date=2007-04-14 |work=[[Broadcasting & Cable]] |accessdate=2009-07-21}}</ref> At the Consumer Electronics Show in January 2009, the first [[prototype]] devices from LG and other manufacturers were demonstrated, including receivers for cars from [[Kenwood Corporation|Kenwood]], [[Visteon]] and [[Delphi (auto parts)|Delphi]]. It was announced that 63 stations in 22 markets would debut the service in 2009. [[Gannett Broadcasting]] president David Lougee pointed out that many of those attending the [[inauguration of Barack Obama]] would likely hear him but not see him; had the new technology been in place, this would not have been a problem.<ref>{{cite news|url=http://www.broadcastingcable.com/article/161893-CES_Broadcasters_Mobile_DTV_Moment.php?rssid=20102&q=broadcasters+mobile+dtv+moment|title=CES: Broadcasters' Mobile DTV Moment|last=Dickson |first=Glen |date=2009-01-11 |work=[[Broadcasting & Cable]] |accessdate=2009-12-03}}</ref> In April 2009, the [[Open Mobile Video Coalition]], made up of over 800 broadcast stations, selected four test stations: Gannett's [[WATL (TV)|WATL]] and ION's [[WPXA-TV]] in [[Atlanta, Georgia|Atlanta]], and [[Fisher Communications]]' [[KOMO-TV]] and [[Belo]]'s [[KONG-TV]] in [[Seattle, Washington|Seattle]].

At the time, only those with prototype receivers could pick up the streams. ION Chairman and CEO Brandon Burgess said mobile DTV lets stations "think beyond the [[living room]] and bring live television and real time information to consumers wherever they may be."<ref>{{cite news|url=http://www.broadcastingcable.com/article/307120-ION_Broadcasts_Mobile_DTV_in_N_Y_D_C_.php?rssid=20068&q=digital+tv|title=ION Broadcasts Mobile DTV in N.Y., D.C.: Hails Its Digital TV "Triple Play"|last=Dickson |first=Glen |date=2009-06-29 |work=[[Broadcasting & Cable]] |accessdate=2009-07-02}}</ref> The Advanced Television Systems Committee started work on mobile DTV standards in May 2007, and manufacturers and sellers worked quickly to make the new technology a reality. The OMVC persuaded LG and Samsung to work together starting in May 2008 so that differing systems (possibly a [[self-destruct]]ing [[format war]]) would not delay or kill the technology. Early in July 2009, the ATSC Technology and Standards Group approved the [[ATSC-M/H]] standard for mobile DTV which all members green-lighted October 15. The public could be using the new devices by 2010, though watching TV on [[cell phone]]s seemed unlikely in the near future since telephone manufacturers did not yet include that capability. The technology was expected to be used for [[poll]]s and even [[voting]].<ref>{{cite news|url=http://www.broadcastingcable.com/article/307463-Mobile_DTV_is_Almost_Official.php?rssid=20065&q=digital+tv |title=ATSC-M/H voted to proposed standard status |last=Dickson |first=Glen |date=2009-07-06 |work=[[Broadcasting & Cable]] |accessdate=2009-07-08}}</ref><ref name=october>{{cite news|url=http://www.broadcastingcable.com/article/358341-Mobile_DTV_Standard_Approved.php?rssid=20292&q=digital+tv|title=Mobile DTV Standard Approved|last=Dickson |first=Glen |date=2009-10-16 |work=[[Broadcasting & Cable]] |accessdate=2009-10-16}}</ref> By the end of the year, the ATSC and the [[Consumer Electronics Association]] began identifying products meeting the standard with "MDTV".<ref name=mdtv>{{cite news|url=http://www.broadcastingcable.com/article/440764-ATSC_Launches_Certification_Program_For_Mobile_DTV.php?rssid=20102&q=digital+tv |title=ATSC Launches Certification Program For Mobile DTV|last=Dickson|first=Glen|date=2009-12-16|work=[[Broadcasting & Cable]]|accessdate=2009-12-17}}</ref> Paul Karpowicz, NAB Television Board chairman and president of Meredith Broadcast Group, said <blockquote>This milestone ushers in the new era of digital television broadcasting, giving local TV stations and networks new opportunities to reach viewers on the go. This will introduce the power of local broadcasting to a new generation of viewers and provide all-important emergency alert, local news and other programming to consumers across the nation.<ref name=october/></blockquote> Later in July, the first multi-station tests began in [[Washington, D.C.]], while single stations in [[New York (city)|New York]] City and [[Raleigh, North Carolina]] already offered mobile DTV. The OMVC chose Atlanta's WATL and Seattle's KONG as "model stations" where product testing could take place. 70 stations in 28 [[media market]]s planned streams by the end of 2009. The Washington test would involve [[WPXW-TV]], [[WUSA (TV)|WUSA]], [[WDCA]], [[WRC-TV]], [[WHUT-TV]], [[WNUV]] in [[Baltimore]], and WNVT, a part of [[MHz Networks]], a multicasting service. All of the stations would have two of more channels each, with "[[electronic program guide|electronic service guide]] and alert data" among the services. 20 sellers of equipment would use these stations to test using the existing standard, but testing the final standard would come later, and tests by the public would happen in 2010, when many more devices would be ready. Obviously, manufacturing large numbers of the devices could not take place without the final standard. LG, however, began mass-producing chips in June. ION technology vice president Brett Jenkins said, "We're really at a stage like the initial launch of DTV back in 1998. There are almost going to be more transmitters transmitting mobile than receive devices on the market, and that's probably what you'll see for the next six to nine months." Devices would eventually include [[USB]] [[dongle]]s, [[netbook]]s, [[Portable DVD Player|portable DVD players]] and in-car displays.<ref>{{cite news|url=http://www.broadcastingcable.com/article/314792-Special_Report_Mobile_DTV_Heats_Up.php |title=Special Report: Mobile DTV Heats Up |last=Dickson |first=Glen |date=2009-07-13 |work=[[Broadcasting & Cable]] |accessdate=2009-07-15}}</ref> [[Executive Office of the President of the United States|White House]] officials and members of [[United States Congress|Congress]] saw the triple-play concept in an ION demonstration on July 28, 2009 in conjunction with the OMVC.<ref>{{cite news|url=http://www.broadcastingcable.com/article/316065-ION_OMVC_Organize_DTV_Showcase_in_D_C_.php?rssid=20068&q=digital+tv|title=ION, OMVC Organize DTV Showcase in D.C.|last=Dickson |first=Glen |date=2009-07-22 |work=[[Broadcasting & Cable]] |accessdate=2009-07-22}}</ref><ref name=LIN>{{cite news|url=http://www.broadcastingcable.com/article/326796-LIN_TV_Develops_Blackberry_App_For_Mobile_TV_Service.php?q=digital+tv |title=LIN TV Develops Blackberry App For Mobile TV Service|last=Eggerton |first=John |date=2009-08-07 |work=[[Broadcasting & Cable]] |accessdate=2009-08-11}}</ref> Another demonstration took place October 16, 2009 with journalists, industry executives and broadcasters riding around Washington, D.C. in a bus with prototype devices.
