Multimedia Broadcast Multicast Service (MBMS) is a broadcasting service that can be offered via existing GSM and UMTS cellular networks. The infrastructure offers an option to use an uplink channel for interaction between the service and the user, which is not a straightforward issue in usual broadcast networks, as for example conventional digital television is only a one-way (unidirectional) system. MBMS uses multicast distribution in the core network instead of point-to-point links for each end device .
MBMS will start to be rolled out in cellular networks during 2008 and gives the opportunity to broadcast TV, film, information such as free overnight transmissions of Newspapers in a digital form and other media in these networks. MBMS has the major benefits that the network infrastructure is already there for mobile network operators and the deployment can be cost effective compared with building a new network for the services. The broadcast capability enables to reach unlimited number of users with constant network load. Further it also enables the possibility to broadcast information simultaneously to many cellular subscribers for example emergency alerts.
MBMS is two services. MB stands for the relatively simple to achieve Multimedia Broadcasting. MS stands for the more challenging, two way Multicast Services.
MB s ( Multimedia Broadcasting s ) main use will broadcasting Television Channels in much the same way as traditional Terrestrial and Satellite TV companies offer TV today.
MB TV will broadcast many channels of TV, some Free to Air paid for by advertising content and others restricted to the Cellular networks call subscribers, as an added value service. Whilst some TV channels will be paid for by subscription.
Free to air, or Free to Subscriber, MB TV will probably be the most exciting. Cellular service providers, will compete to win audience share by commissioning the very best in entertainment. Free to air TV will generate up to $5 a day advertising revenue per subscriber.
Revenue from adverising content within TV and Newspaper MBMS services is forcast to be be greater than call revenues in years to come.
Cellular service providers, are each expected to broadcast, one or two high resolution TV channels designed for viewing on lap tops, desk top PC s and on domestic TV screens, as well as Cellular Phones. And a further 5 or 6 channels designed for viewing on a Cell Phone screen format. The channels designed for Cell phone screen viewing will be viewable on Domestic TV s and Laptops but with a boarder around the picture, optionally containing advertising. The number and the resolution of TV Channels broadcast, will increase at night when Cell Phone transmitters are at present under utilised.
Using the Cell Phone transmitters to Broadcast TV has considerable advantages over traditional terrestrial and satellite TV being truly portable. Reception is not reliant on roof top or external aerials. Cellular Telephone broadcasts use micro wavebands that penetrates buildings more effectively than tradition terrestrial TV broadcasts. Cellular TV broadcasts will be received using an aerial smaller than a sugar cube. And, because the signal is delivered to a PC or Smart phone the programs can be stored on the Computers. Smart phones memory for use at the Users convenience.
Cellular Multimedia Broadcast, TV receivers, as with, WiFi and Digital terrestrial TV receivers, be built into future generation of TV s and PC s.
Television viewers will go over to watching the, more convenient, Cellular Television Broadcasting Channels, in their homes, in the same way that over the past 20 years people have gone over to using cellular phones when they used to use land lines.
Broadcasting TV channels from cell phone transmitters, is the first practical solution to watching live Television in a moving automobile or Bus. Tests have shown that reception is not adversely affected at speeds in excess of one hundred miles an hour. It is believed that within a few years of the Cellular MB / MBMS launch automobiles, busses and Coaches will have MB television screens built in.
MBMS and 4G . Cellular TV Broadcasting and MS will give the cellular service providers a very considerable return on their investment in 3G licences and will bring forward the launch of 4G.
MBMS will for the first time enable cellular networks to distribute, by shared broadcasts a new generation of vibrant, entertaining, multimedia rich newspapers in a digital form, sent out simultaneously to all cell phone users within each transmitter footprint by a single shared transmission.
Received and stored onto the memory of, a new generation of Newspaper Phones, Reading and viewing made easier by, folding low energy screens. 10 + GB of memories, to store the Multimedia Broadcast Newspapers, that will contain Video, Audio, Music, and Computer Games as well as written text and photos. Utilising the presently-unused transmitter resource in the night-time hours with smaller updates broadcast as fresh news breaks.
Popular Newspapers, will probably be free. Advertising within the content, will provide an important new revenue stream for the Cellular service providers, estimated at between $1-$5 per reader per day. URLs and telephone numbers, within the content will when clicked, activate the users cellular telephone, seamlessly connecting the user to the advertiser, giving the service providers further revenue from calls and Internet connections.
MBMS newspapers will be more user friendly than reading newspapers on the Internet, navigating from story to story will be instant, as the content is accessed from the memory of the cell phone, Videos and Photos open instantly without buffering. Once the Newspaper is received in the middle of the night, the user does not need to have a phone line or wireless connection to read their Multimedia Newspaper.
MBMS receivers will be built into lap top and desk top computers in a similar way that WiFi are today. Enabling personal computer users to receive MBMS TV and Newspaper services.
MBMS will help to reduce global warming. As traditional paper-newspapers become a thing of the past. The delivery of Newspaper data by MBMS will help to reduce the Newspaper Industries carbon foot print from the present more than 100,000 tons a year, close to 1% of the worlds Co2 pollution, to a relatively green carbon footprint.
The reading of Newspapers, on Cell Phones and PC s, delivered by MB will over the next twenty years, save millions of acres of trees from being cut down for pulping into paper for traditional newspapers. This will further help the Planet by absorbing and locking away hundreds of thousands of tons of Co2 emissions in the extra wood grown by the 100s of Millions of trees saved.
