Astro eyes one million users for HD service

KUALA LUMPUR: Pay-TV operator Astro All Asia Networks plc is targeting one million household subscribers for its newly-launched Astro B.yond, a multi-phased innovative service, starting with the country’s first high-definition (HD) broadcast.

“Our target is 30% of our customer base, which is expected to reach three million by year-end.

“We should be able to secure at least half of the one million in the next 12 to 18 months,” said Astro TV chief executive officer Datuk Rohana Rozhan after the launch of Astro B.yond yesterday.

At 48% penetration of Malaysian TV homes, Astro is currently streaming to 2.875 million homes.

Rohana said about 1.2 million of Astro’s customers were HD-ready, adding that according to an industry report, 59% of all televisions sold in the first half of this year were HD-ready and sales in this segment were growing.

“All data indicate that Astro’s introduction of HD service comes at an opportune time and the market is ready for HD content,” she said.

Rohana said the investment in HD broadcast technology and related services would fall under the company’s capital expenditure (capex) and operating expenditure (opex).

“Our capex and opex for the financial year ending Jan 31, 2010 (FY10) are RM100mil each while RM200mil and RM150mil have been allocated for capex and opex respectively in FY11,” she said.

She added that the capex and opex would come from the company’s internal fund.

On Astro B.yond, Rohana said it offered customers more innovative services which would be introduced in phases. Customers can sign up for Astro B.yond and access to HD services for an additional RM20 per month for a 12-month period. They will receive a new B.yond box, new smart card, new outdoor dish, HD multimedia interface cable and new remote control.

New set-up installation fee will be waived in exchange for the existing box.

HDTV offers viewers an enhanced entertainment experience with better quality images in true definition details, cinematic surround sound, vibrant colours, wider screen and about five times the detail of standard definition TV.

Rohana said Astro would kick off Astro B.yond with three key genres that were recognised as HD content drivers globally – sports, movies and documentaries.

Astro Supersport HD, HBO HD, National Geographic Channel HD and History HD will start screening on Dec 18, followed by ESPN HD next month.

It plans to launch another five HD channels next year.

Over the next 24 months, Astro B.yond will introduce an intuitive electronic programming guide, digital video recording, video on demand and Internet protocol TV connectivity.

Track anything

ATS Automobile has launched a GPS device for keeping track of your valuable ­possessions.
MyNav GPS Tracker is one of the smallest tracking devices, making it easy to attach to any surface or object, according to Kithsiri Kumar, the company’s director.

The device works by using a combination of three technologies — GSM, GPRS and GPS. It can send out an SMS alert with its current location and moving speed if it is in transit.

And when the tracker is not able to achieve a GPS lock, it would still be able to roughly triangulate its position using cell towers.

“Up take of the device has been good as people are considering personal tracking devices as an additional security measure for valuable assets such as cars,” he said.

To date the company has sold over 200 units of the device over the course of three months, said Kithsiri.

The tracker can also be used as a personal security device for children as it also comes with a panic button. Pressing this button will make the device send out an SMS every three seconds.

Other uses include voice surveillance as it allows users to call the device and listen in on what’s going on via the tracker’s built-in microphone.

ATS Automobile says the MyNav GPS Tracker is able to last up to one week or 50 hours of continuous usage on a single charge.

The tracker would also alert the user via SMS if it’s running out of power.
MyNav GPS Tracker retails for RM899. — CHONG JINN XIUNG

Sony Ericsson Droid Phone

Sony Ericsson today announced its Xperia X10 smartphone, based on Android, which features a customized software layer called UX built on top of the open-source operating system. It’s the first of a family of smartphones that the company plans to deliver in the first half of next year, and won’t be available until then. While it has some high-end features that could help it compete with the much-hyped Droid, unlike Motorola’s and Verizon’s handset, this phone has a surprising shortcoming.
The Xperia X10 — even though it won’t ship until next quarter — will run Android 1.6. The Droid runs Android 2.0, which has a slew of advanced features and is shipping this month. In fact, most of the Droid’s substantial marketing campaign is built around new features in Android 2.0.
The X10 also has a 1-GHz Qualcomm Snapdragon chip, which many of the newer Android-based smartphones are moving to, and the iPhone runs. While the Droid phone has a 5-megapixel camera, the Xperia X10’s is 8.1 megapixels with video recording and 16x digital zoom. jkOnTheRun points out some of the other notable features:
4-inch capacitive touchscreen at 854 x 480 resolution
Android 1.6
1GB of internal memory, 8GB of included microSD storage
GPS, Wi-Fi, stereo Bluetooth
Quad-band GSM and two flavors of HSPA support, depending on model (UMTS HSPA 900/1700/2100 or UMTS HSPA 800/1900/2100)
The Xperia X10 will run applications from both the Android Market and Sony Ericsson’s PlayNow Arena. There is no price available yet, but it already looks like this phone will have a tough time competing unless it sees an upgrade to Android 2.0 as it goes to market.

New GPS Service Free, More Accurate in Europe

New GPS Service Free, More Accurate in Europe
Daniel Ionescu

Oct 2, 2009 10:28 pm

The European Union introduced on Thursday a free global positioning system that it claims is almost five times more accurate than the U.S. system currently in use.
Called the European Geostationary Navigation Overlay Service (EGNOS), the system uses three satellites and a ground network of about 40 ground positioning stations and four control centers.

The U.S. military-run GPS system, in widespread use across the globe, offers a 10-meter (32 feet) accuracy level, but EGNOS promises to fine-tune this experience and deliver accuracy levels to around 2 meters (6 feet).

EGNOS only covers the 27 member-states of the EU at the moment, but it is expected to expand to neighbouring nations and Northern Africa in the near future. The service is free for use by anyone within the coverage area with a GPS/SBAS compatible receiver.

The EU sees various uses for its more-accurate GPS system, which was in testing mode since 2006. Farmers would benefit from precision spraying fertilizers, and blind people could have personal guides. It could automatically charge road tolls or pay-per-use car insurance.

It is also expected that the next generation of GPS-enabled smarptohones such as the Apple iPhone, Palm Pre or Google Android devices, will benefit from the improved accuracy of EGNOS. Some standalone GPS devices might soon use EGNOS as well, given that the manufacturers release firmware updates to support the system.

EGNOS is mainly the precursor of EU's Galileo project, Europe's own GPS system, which has been plagued with delays in the last years and is expected to begin operating in 2014.

Meanwhile, American users have had their EGNOS equivalent for some tine now, called Wide Area Augmentation Service (WAAS) and the Japanese are working on a similar system called Multi-Functional Satellite Augmentation System (MFAS).

Assisted GPS

From Wikipedia, the free encyclopedia

Assisted GPS, generally abbreviated as A-GPS, is a carrier network dependent system which can, under certain conditions, improve the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.[1]

Conventional or "Standalone GPS" operation uses radio signals from satellites. In very poor signal conditions, for example in a city these signals may suffer multipath where signals bounce confusingly off buildings, or be weakened by passing through walls or tree cover. When first turned on in these conditions, some non-assisted GPS navigation device may not be able to work out a position due to the fragmentary signal, rendering them unable to function until a clear signal can be received continuously for up to 40 seconds. (the time needed to download the GPS ephemeris.) Some newer receivers are better at handling these situations.
An A-GPS system can address these problems in several ways, using an assistance server or other data from a network.

Assistance falls into two categories:

Using information known to the assistance server but not the phone.
It can supply orbital data and/or almanac for the GPS satellites to the cell phone, enabling the cell phone to lock to the satellites faster in some cases.
The network can provide atomic time (Accurate Time Assistance)
The device capturing a snapshot of the GPS signal, with approximate time, for the server to later process into a position.[2]

Accurate, surveyed coordinates for the cell site towers allow better knowledge of local ionospheric conditions and other errors affecting the GPS signal than the cell phone alone, enabling more precise calculation of position. (See also Wide Area Augmentation System)
Calculation of position by the server using information from the phone.

The assistance server has a good satellite signal, and plentiful computation power, so it can compare fragmentary signals relayed to it by cell phones, with the satellite signal it receives directly, and then inform the cell phone or emergency services of the cell phone's position.

As an additional benefit, in certain types of A-GPS, both the amount of CPU and programming required for a GPS phone is reduced by offloading most of the work onto the assistance server. (This is not a large amount for a basic GPS – many early GPSs utilized Intel 80386-class 16 MHz CPUs or similar hardware.)

A typical A-GPS-enabled cell phone will use a data connection (internet, or other) to contact the assistance server for A-GPS information. If it also has functioning autonomous or standalone GPS, it may use standard GPS, which is sometimes slower on Time To First Fix, but does not lead to network dependent downsides, such as failure to work outside of network range, or charges for data traffic.[3] Some A-GPS solutions do not have the option of falling back to standalone or autonomous GPS.

High Sensitivity GPS is an allied technology that addresses some of the same issues in a way that does not require additional infrastructure. However, unlike some forms of A-GPS, high sensitivity GPS cannot provide instant fixes when the phone has been off for some time.


Some A-GPS devices lack standalone GPS capability. They may not function at all unless the device has an active subscription to a network, and is in range of that network. Others offer additional Local Positioning Systems and use whatever ones are available at the moment. Conventional GPS receivers are only limited in the opposite sense, offering service whenever good GPS signals are available.

Some A-GPS solutions inherently give the users position very accurately to the assistance server. However, for mobile phones, the privacy concern this represents is somewhat diluted by the fact that the network already knows the position of the phone to within several hundred meters or better.
