What mobile DTV (MDTV) is?
Which networks can deliver true DTV experience to mobile devices?
True Mobile Digital TV (MDTV) means watching live Digital TV (DTV) on mobile devices,
with a user experience similar to the one the consumers are used to on their home TV. This
means having a big variety of shows to watch, with high quality high frame rate video and
quick response time for channel switching. While there are elements in the market that try to
confuse true MDTV with other forms of TV/media distribution that offer poor quality video
and a poor offering of channels, true MDTV is distributed through a dedicated broadcast
Soon real estate professionals will be able to stream their live events and seminars through MDTV channel outlets, keeping consumers up to date on current events within their general areas. Imagine getting updates from destination places around the world, Vacation rentals for lease and a tour performed by the actual owner or representative. Choosing you vacation destination in the near future may become more real than ever before. Rest assure, RealtyGo will be looking into this futuristic type channeling to deliver real estate listings and information as efficiently as possible for everyone using Mobile devices. Keep a look out for MDTV and a new technology boom; does Youtube ring a bell… .
The most common alternatives of DTV distribution to mobile devices are to get the DTV
content through the WiFi network or through the cellular network.
This article explains the different available methods, why the true MDTV experience can be
achieved only by a dedicated broadcast MDTV network and how the MDTV offering can be
broadened by wise usage of all the methods for distribution of DTV, which can provide the
best value and best user experience to the consumer.
1 Methods for Mobile DTV distribution
1.1 Distribution of Mobile DTV through the cellular network
The cellular network is conceptually a unicast network, meaning that the content is
transmitted to each receiver individually, even if several receivers are consuming the same
content simultaneously. Thus with the current deployed and used technologies, distribution
of mobile DTV content through the cellular network is no different than the distribution of any
other data through the cellular network.
There are some technologies for broadcasting content over cellular networks, including
Multimedia Broadcast Multicast Service (MBMS), Integrated Mobile Broadcast (IMB), and
Evolved MBMS (e-MBMS) for LTE networks. These technologies are currently either not
mature yet or not widely used (i.e. deployed). Nevertheless, though currently cellular
networks use unicast transmission for distributing DTV content, this article refers also to
optional future usage of these broadcast technologies.
The main concern that is related to mobile DTV distribution is its relatively high bandwidth
requirement. Watching live DTV content at good quality on mobile devices requires
continuous reception of streaming audio/video (A/V) content at a rate of about 500Kbps.
This reception rate enables the display of good quality video at QVGA resolution and at a
frame rate of 30 frames-per-second (FPS).
In developed countries, current cellular networks are already congested with the increase of
video consumption (YouTube, etc.), live gaming, web surfing and other data-consuming
applications over mobile devices. These networks do not have the bandwidth to provide live
DTV services with a similar user experience to stationary DTV in terms of video quality and
content variety. Recent testimonials to this problem were made public by AT&T, which is
now setting a cap for its subscribers’ data usage, since they need to “ease the congestion”

BARCELONA, Spain–Motorola Mobility (NYSE:MMI) CEO Sanjay Jha confirmed that its first tablet, the Android-powered Xoom, will retail for $800 when it goes on sale unsubsidized from Verizon Wireless (NYSE:VZ). Speaking to reporters here on the sidelines of the Mobile World Congress trade show, Jha justified the price of the tablet, which is higher than a similar version of Apple’s (NASDAQ:AAPL) iPad, by saying that the Xoom’s eventual upgrade to LTE gives it a leg up on the competition.
A 32 GB version of the Xoom with Verizon’s EVDO data service will retail for $800. The 32 GB version of the iPad with AT&T Mobility’s no-contract (NYSE:T) HSPA+ service retails for $729. “We felt that our ability to deliver 50Mb/s would justify the $799 price point,” Jha said. “It is 32 GB with 3G and a free upgrade to 4G. Being competitive with iPad is important. We feel that from the hardware and capabilities we deliver we are at least competitive and in a number of ways better [than the iPad].” Verizon has said its LTE network delivers average real-world downlink performance of 5-12 Mbps.
The Xoom runs on Android 3.0, or “Honeycomb,” and boasts a dual-core Nvidia Tegra 2 processor. It also features a 10.1-inch widescreen HD display. The device supports 1080p HD video and HDMI output to display content on larger HD screens. Additionally, the Xoom has a front-facing, 2-megapixel camera for video chats over Wi-Fi, EVDO or or LTE, as well as a rear-facing 5-megapixel camera that captures video in 720p HD. The Xoom will be upgraded to LTE sometime in the second quarter.
Jha said that Samsung’s return rate and sell-through rate with the Android-powered GalaxyTab have been “concerning,” but said he was confident enough to launch the Xoom at the $800 price point. Importantly, Verizon has not yet revealed its LTE data plans for tablets or smartphones.
Jha also said that Motorola will release a Wi-Fi-only version of the Xoom. He would not be drawn on the exact price, but said it would be “meaningfully cheaper. The price is set by iPad at $599, and we will be right around there.” The 32GB Wi-Fi-only version of the iPad sells for $599.
In an apparent slip, Jha also seemed to divulge the existence of Google’s music service, which Google has never publicly acknowledged. Jha said that an ecosystem is composed of applications, developers and services. “Google’s mobile services–and that includes music services, video services…” Then, according to the Wall Street Journal, correcting himself, he said, “There will be music service, there will be video service.”
T-Mobile USA announced it will sell the Android-powered G-Slate tablet, built by LG, “in coming months.”
The companies provided little in the way of details. The G-Slate will run the “Honeycomb” version of Android 3.0, which is designed for tablet-style gadgets, and will support T-Mobile’s HSPA+ network, which the carrier has branded as 4G. The companies did not release specifications, pricing or a launch date.
The announcement of the G-Slate came mere minutes after Motorola Mobility (NYSE:MMI) unveiled its own Honeycomb-powered tablet, the Xoom for Verizon Wireless (NYSE:VZ)–a possible move by T-Mobile and LG to lessen the splash of Motorola’s announcement here at the Consumer Electronics Show.
The G-Slate represents a further evolution of both T-Mobile USA and LG’s respective strategies. T-Mobile has been working to broaden and deepen its lineup of high-end devices, and currently sells the Samsung GalaxyTab tablet and the HSPA+-powered G2 and myTouch 4G smartphones. All of the gadgets run Google’s (NASDAQ:GOOG) Android platform.
For LG, the G-Slate brings to a close the company’s troubled tablet journey. LG announced in July its intention to offer an Android tablet in the fourth quarter of 2010. However, in October the company said it scrapped plans to offer an Android 2.2 tablet, arguing Android 2.2, dubbed Froyo, isn’t suitable for tablet-sized devices.

Qualcomm (NASDAQ:QCOM) agreed to purchase WiFi chipmaker Atheros for $3.1 billion, or $45 per share.
San Jose-based Atheros is known for its innovations with WiFi chipsets. Earlier this year the company teamed with Wilocity to make WiGig-WiFi chips, and it also has been exploring ways to combine WiFi with powerline systems.
The deal is the largest ever for Qualcomm, and is expected to close sometime in the first half of the year. The New York Times first reported on the tie-up late Tuesday.
The acquisition would provide Qualcomm, the world’s largest maker of cell phone chipsets, with a way to diversify beyond its core market into new growth areas such as tablets and smartphones, which require more processing power and must be able to connect via many different technologies besides cellular, such as WiFi, Bluetooth and GPS. The deal could also allow Qualcomm to compete more heavily with longtime rival Broadcom.
This isn’t the first time Qualcomm has tried to get into the WiFi game. In 2006, the company purchased a WiFi chipmaker Airgo Networks.
Qualcomm is fresh off another big deal. In late December, the firm sold its 700 MHz spectrum that is uses for its soon-to-be-decommissioned FLO TV service to AT&T Mobility (NYSE:T) for $1.925 billion.

This is by far some of the most exciting news we have read lately. Combing WiFi with local powerlines all over the U.S. – What will they think of next?
WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications protocol that provides fixed and fully mobile Internet access. The current WiMAX revision provides up to 40 Mbit/s with the IEEE 802.16m update expected to offer up to 1 Gbit/s fixed speeds. The name “WiMAX” was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL”. http://en.wikipedia.org/wiki/WiMAX
Clearwire (NASDAQ:CLWR) said it expects to raise over $1.1 billion through new debt offerings, a move that offsets its urgent need for new funding as it continues to build its mobile WiMAX network.
Clearwire said the new debt will come in three separate offerings: one offer of $175 million in first-priority senior secured notes due in 2015, $500 million of second-priority secured notes due in 2017, and $500 million of exchangeable notes due in 2040. Analysts have said that the company likely will need billions more to continue building its network over the next few years.
“This solution appears to be the least attractive of the many that we have considered,” wrote TownHall Investment Research in a note explaining its decision to lower its rating on Clearwire from Buy to Avoid. “With a maximum of less than $2 billion anticipated in this raise, the company remains well short of its longer term funding needs and will likely have to further curtail some of its 2011 build-out plans. Additionally, we believe this approach represents a funding of last resort after the company has been unable to piece together a non-public financing that might have included T-Mobile as a new partner and distributor. With this funding, the company may have done little about investor long-term funding concerns, other than to kick the can down the road.”
The company announced a series of measures last month to conserve cash as it searched for new funding options. Clearwire CEO Bill Morrow said at the time that the company was considering a range of funding options, including new equity funding from existing shareholders as well as non-strategic investors; debt-based financing; or selling spectrum that the company does not need.
Sprint Nextel (NYSE:S), which holds a 54 percent stake in Clearwire, has said it is in negotiations with Clearwire over funding, but has given no indication that more equity financing will be forthcoming. Sprint CEO Dan Hesse stopped short in November of promising more funding, though he did say that Sprint has “historically injected more cash into the company.”
In other Clearwire news, the company said Sprint nominated William Blessing, Mufit Cinali and Hossein Eslambolchi for the three open seats on Clearwire’s board. Blessing is a consultant to Burns & McDonnell where he advises clients on smart grid and telecommunications strategy; Cinali is a managing director with Springwell Capital Partners; and Eslambolchi is a technical advisor to Ericsson (NASDAQ:ERIC) and the University of California School of Engineering.
In late September, Hesse, Steve Elfman, Sprint’s president of network operations and wholesale, and Keith Cowan, Sprints president of strategy and corporate initiatives, resigned from the board. Clearwire said the changes were made out of an “abundance of caution to address questions raised by Clearwire regarding new developments in antitrust law.”
Clearwire also launched a new modem, the “Clear Modem with WiFi,” that supports both WiFi and the company’s WiMAX service. The modem will retail for $120.
