The Greater China region, spanning mainland
China, Hong Kong and Taiwan, accounts for about 80 percent
of the world's remote control production. The total current
monthly production volume is estimated at 100 million units,
based on data from the companies in this report. The total
monthly capacity is 148 million remote controls.
Mainland China's supplier base comprises
some 100 makers, half of which are medium and large companies.
Twenty percent of the mainland's remote control makers are
covered in this report. Taiwan's industry, affected by competition
from the mainland, has been reduced to some 20 active makers.
This report covers 30 remote control manufacturers:
20 from mainland China, seven from Taiwan and three from
Hong Kong. The respondents represent a quarter of Greater
China's supply base. These companies provided manufacturing,
export, sales and product development information and forecasts,
from which Global Sources gleaned these findings:
The line is being strengthened by the
growth of the home entertainment and home automation sectors
since remote controls are usually bundled with TVs, DVD
players and home appliances.
Single and universal or multiple device
remote controls using IR and RF technologies are available
from makers, with IR remote controls being the mainstream.
The line-of-sight (LoS) limitation of IR technology, however,
has prompted the rise of RF-based remote controls.
Mainland China's output will continue
to largely consist of low-end to midrange IR-based models.
Most Taiwan makers focus on high-end IR
and RF units, with some companies investing in the development
of ZigBee and Bluetooth models. These models, however, are
not foreseen to dominate output in Greater China in the
near term, as the costs of Bluetooth and ZigBee chipsets
are still prohibitive for makers in the region.
Single-device remote controls have a solid
supply base, but universal remote controls are gaining ground.
Mainland China's export value is projected
to reach US$121 million i

transforming the user experience for a range of electronic
devices, from cell phones to gaming consoles to wireless
peripherals. With over 90 million set-top boxes sold worldwide
every year, the addition of Bluetooth functionality in these
devices will enable STB makers to offer unique and differentiated
features in their products. Given Broadcom's strong leading
position in the STB market, the company is poised to become
the vendor of choice for Bluetooth-enabled set-top box technology.
"Bluetooth makes sense as it solves
the immediate need of providing home phone line connectivity,
and allows audio and remote control use without the need
for line-of-sight infrared (IR) technology," said Jim
Muth, Senior Product Line Manager of Broadcom's Wireless
Personal Area Networking line of business. "In addition,
Bluetooth opens up a whole new world of innovative and exciting
applications by enabling set-top boxes to have connectivity
to the hundreds of millions of Bluetooth devices that are
sold each year."
There are some immediate benefits recognized
by enabling Bluetooth technology into set-top boxes. The
following includes a short list of benefits:
Enables a cellular network to be used for ordering or recovering
orders for pay per view or other services when a land line
is not present or not conveniently located near a STB. This
capability will be demonstrated at IBC2007.
Allows channel changes with the entertainment cabinet door
closed, eliminating the need for line-of-sight IR technology.
This capability will also be demonstrated at IBC2007.
Enables wireless headsets and wireless speakers.
Enables more powerful remote controls such as:
Whole house remotes with two-way services
Sound, vibration and motion sensing controllers
User-friendly remotes with displays
Enables cell phone downloads of pictures for storage or
display.
Enables Bluetooth connections from STBs to landline phone
jacks.
Enables Bluetooth mouse and keyboard connections.
Enables Bluetooth connections of cell phones, laptops and
PDAs to STBs and provides synchronization of calendars,
meetings, etc.
"Bluetooth has been very successful
in mobile phones, PCs, and video game consoles, and it has
solid potential in other consumer devices as well,"
said Brian O'Rourke, Principal Analyst for In-Stat's Enabling
Technologies Group. "Broadcom's strong position in
both Bluetooth and set top box solutions make this market
a potentially strong one for Bluetooth."
Technical Information
Broadcom's new Bluetooth and set-top box
reference design, to be demonstrated at IBC2007, is based
on the company's high definition (HD) MPEG-4 reference platforms.
It utilizes the very successful BCM740x series of HD MPEG-4
devices in conjunction with Broadcom's BCM2046 Bluetooth
solution. The BCM2046 is the industry's first solution to
combine Bluetooth 2.1 features, enhanced data rate (EDR)
technology and a Class 1 radio frequency transceiver in
a single, monolithic chip, featuring the most advanced Bluetooth
features to provide superior short range wireless connectivity
for a variety of applications. It is also the industry's
most highly integrated Bluetooth solution that can reduce
external bill of materials cost by more than 80 percent.
The wide array of Bluetooth functionality
and applications is enabled by Broadcom's market leading
Bluetooth software offering. Featuring the most complete
set of profiles in the industry, Broadcom BTE software allows
STB developers to offer a broader range of Bluetooth applications
and more complete access to the substantial ecosystem of
Bluetooth peripherals and devices available. Competing software
solutions offer limited application support, making Broadcom's

Remote control: Easy RF design delivers more features than
IR at low cost
IR's simplicity, low-cost and low-power
consumption has ensured its widespread adoption but the
technology is not without its weaknesses. Here's an overview
of an RF technology that has all of IR's advantages and
none of its deficits.
By Kjartan Furset, Senior Application
Engineer, Nordic Semiconductor

Wireless Net DesignLine
(10/02/2007 5:41 H EDT)
For the most part, remote-control consumer electronic equipment
still uses IR wireless communication. It's simple to design
in, robust, cheap to manufacture and yields a controller
that can run for months on two to four AAA 1.5 V cells.
But IR is showing its age. Originally designed in the late
seventies to replace ultrasonic devices when a greater range
of functionality was required, IR remotes are inconvenient
to use when navigating the complex multi-layered menus typical
of today's digital electronics. (See sidebar "A short
history of the remote control.").
Users must point the remote directly at
the IR receiver unobstructed by furniture, pets and people.
The technology is almost always a uni-directional (bi-directional
communication is possible, but it's expensive and prone
to interference from other light sources).
Today's consumers also prefer to have
a user interface on their remote offering intuitive instructions
and information about the media they're listening to or
watching.
Fortunately, a new generation of RF remotes
promises to finally match the convenience of IRanamely design
simplicity, low cost and long battery lifeawhile providing
consumers with wireless connectivity that can support the
more advanced menu-based browse facilities now common to
home entertainment devices.
Better yet, the silicon vendors are making
great strides to simplify the traditionally tricky RF design
process by offering industry-proven transceivers plus reference
designs, customised protocols and RF expertise to assist
inexperienced designers.
IR basics
IR is electromagnetic (EM) radiation of wavelengths longer
than visible light, but shorter than RF spanning three orders
of magnitude between 750 nm and 1 mm. IrDA, the Infrared
Data Association, champions IR in the electronics sector
and most offerings adhere to the organization's standards,
aiding interoperability.
IR remote controls use IR LEDs to emit
radiation that's focused by a plastic lens into a narrow
beam. Data is encoded by modulating the beam to provide
immunity from other IR sources such as fluorescent lights.
The receiver uses a silicon photodiode to convert the IR
radiation to a current for decoding by the receiver's MCU
as shown in Figure 1.

IR doesn't penetrate wallsaalthough it can be reflected
by walls and ceilingsaand so generally does not interfere
with other devices in adjoining rooms. A simple IR remote
comprises a keypad to input instructions, a resonator to
provide a reliable clock base, an 8-bit MCU to detect key
presses and modulate the IR signal and an LED to generate
the IR.
There are many modulation protocols but
most are frequency or format variations of a few base protocols.
Examples include amplitude modulation, frequency modulation
or pulse modulation.
For example, with pulse distance encoding,
pulses remain the same length, while intervals between are
either long or short (representing "0" and "1"
respectively) as shown in Figure 2.

Figure 2: IR remote pulse distance encoding protocol .
This protocol is favored by Japanese consumer electronics
companies and features a data payload of 8 bits address
and 8 bits command, sent twice for reliability.
In this example, a 9 ms train pulse precedes
the data, followed by a 4.5 ms mark, then around 54 ms for
the address and command information. IR communication is
typically one way.
That means the remote has now way of knowing
if the signal has been received. The remote will dumbly
repeat the command as long as a button is pressed. This
example protocol provides repeat frames every 110 ms, meaning
the IR remote control is transmitting for perhaps 90 ms
during a half-second key press key press (See Figure 3.).

Remote control: Easy RF design delivers more features than
IR at low cost

At, for example, 50 key presses per day, that's a duty cycle
of around 0.005 percent. While operating at, for instance,
2V, the remote draws around 100 mW. Negligible power is
drawn while the remote is in "standby" mode.
Two AAA cells connected in series, with a capacity of 900
mAh, provide 2 x 1.5 V x 900 mAh = 2700 mWh. Assuming no
DC-to-DC conversion (to keep costs down), and discarding
voltage reduction as the battery ages, battery life is 2700
mWh/100 mW = 27 hrs. However, with a duty cycle of 0.005
percent, users would not expect to change batteries for
many months or even years.
However, while IR's simplicity, low-cost
and low-power consumption has ensured its widespread adoption,
the technology is not without its weaknesses.
Imagine the consumer of a wall-mounted
air conditioner for example; to change the temperature,
the seated user either takes a chance that the IR will reflect
from surfaces such as walls and ceilings or twist and turns
to ensure his remote aims directly at the air conditioner
to ensure alignment of IR emitter and receiver.
How much easier would it be to just press
a button, no matter what the positioning of the remote,
for guaranteed communication This characteristic also enables
wireless implementation of wall mounted control units.
In a second example, the proliferation
of media centersacentral PC-based entertainment devices
serving as sources of music, video, and other digital filesafinds
consumers wanting to change volume, channel or website from
another room where satellite TV, speakers or monitor are
situated.
Traditional IR remote controls rely on
line-of-sight (or at least direct reflection) and have a
range restricted to a few meters.
Third, consumers are increasingly demanding
two-way communications. While it is theoretically possible
to create two-way communication with IR, real life problems
such as (light) interference and low data rate make this
a poorly performing system.
Moreover, attempting to incorporate two-way
communications complicates the remote control's design,
adds cost and drains battery power, canceling out the inherent
advantage of the IR remote design.
An RF link solves the problem. Taking
the media center example again, consider a user in her study
listening to music; the media center is set to shuffle the
digital music selection and an unfamiliar but pleasing track
is played; with an RF link the user is able to casually
glance at the remote's LCD to identify the track.
She's also offered choices of "next
track" (named), or "similar tracks of this genre"
(again identified) or simply a "repeat" function.
All this is enabled from the remote without even being in
the same room as the source.
The RF alternative
RF has been an option for remote control for some time (it
was first used over a century ago (See sidebar "A short
history of the remote control."). but until now the
technology's relative expense, design complexity and power
consumption have made it uncompetitive with IR for the vast
majority of applications.
To enable this, the nRD24H1 also includes
all firmware needed to make a remote control. The key part
of this firmware is a complete two-way RF protocol stack
for remote control applications.
The protocol stack is implemented as a
standalone software module providing an API (application
programming interface) to the application layer. On top
of this protocol stack, a simple application layer example,
specific to the six button application board, is also included.
Consequently, there is no need to come
to grips with all the details of the RF protocol stack;
programmers can instead focus on modifying and enhancing
the application layer code. All the firmware for the reference
design is provided as open source ANSI-C code enabling anyone
to use it directly or port it to their own microcontroller
platform.
The protocol stack provides an ultra-low
power two-way communication link with frequency hopping
capabilities, dubbed a frequency agility protocol (FAP).
This means that one- or two-way remote
controls can be implemented without having to worry about
RF link up, synchronization, co-existence with other RF
systems or protocol power management. It requires just 3.5
kByte code space in the microcontroller and is hence highly
efficient compared with Bluetooth's heavyweight (250 kByte)
protocol stack.
The protocol offers two modes: Low latency
mode and low power mode.
In low latency mode, when a button is
pressed the device (the remote control) powers up, transfers
the command input to the host (USB dongle) and receives
data back if requested.
This cycle takes around 500
