Mobile Phone Patent Abstract
The invention relates to a method for transmitting image and sound
from a mobile phone to an ordinary analog television receiver using
a mobile phone accessory. The invention relates to third generation
UMTS-/IMT 2000 data terminal equipments, all kinds of GSM-applications,
such as: WAP, HSCSD, GPRS, EDGE and CDMA-phones. The invention is
based on that the accessory module (2) is attached to an ordinary
analog television receiver (3). Bluetooth technology is exploited
in data transmission from the mobile phone to the accessory attachable
to the television. Because of its function, smallness and essence
the accessory module is suitable as mobile phone accessory. The
accessory module uses supply current. The module operating as an
accessory comprises in addition to the actual modification part,
also a Bluetooth accessory, which receives image and sound transmitted
by the modile phone, e.g. UMTS data terminal equipment. The modification
part converts signals conformable to each equipment type to RGB-controlling
signals and sound. The Bluetooth receiver in the module is attached
to the converter by using an interface conformable to USB-standard.
The Bluetooth accessory is attached to the mobile phone, this accessory
can forward image and sound received by the mobile phone to the
television receiver module nearby in the air interface in the free
24 Ghz frequency band.

Mobile Phone Patent Description
An object to this invention is a method according to the preamble
in claim 1, for transmitting image and sound from a mobile phone
to an ordinary analog television receiver using mobile phone accessory.
The invention relates to third generation UMTS (Universal Mobile
Telecommunications System) data terminal equipments, all kinds of
GSM-applications, such as: WAP (Wireless Access Protocol), HSCSD
(High Speed Circuit Switch Data), GPRS (General Packet Radio Service),
EDGE (Enhanced Data Rates for GSM Evolution) and CDMA (Code Division
Multiple Access) phones and IMT (International Mobile Telecommunication)
2000 data terminal equipments.
Previously known in the art is that mobile phones have their own
displays where all information is viewed. So far the display has
mainly been integrated to the phone device.
A problem with the technology mentioned above is that there are
lot of applications where it does not do justice, such as viewing
internet-pages or for a video phone function. In the near future
these will become very utilized. On the other hand, because of the
small display also watching video images will be problematic, despite
that mobile phone displays are being developed and also slightly
enlarged. Monitors which are developed for e.g. UMTS-mobile phones,
will be very expensive and therefore are not suitable for most households,
but only for working environment. In addition, many of the users
suffer from poor eyesight, causing the smallness of the mobile phone
display to be even more a bigger problem, for example, already when
reading SMS messages.
The object to this invention is to eliminate inadequacies in the
prior art and accomplish an altogether new method which can be used
for transmitting information from a mobile phone display to an ordinary
analog television screen and at the same time transmitting sound
to the television receiver, using a mobile phone accessory.
The invention is based on that an accessory module is attached
to an ordinary analog home television receiver (3). Bluetooth technology
is exploited in transmitting data from the mobile phone (1) to the
accessory (2) attached to television. Because of its function, smallness
and essence the accessory module is suitable as mobile phone accessory.
The accessory module uses supply current.
The module (2) is coupled to the SCART-connector in the TV (3),
the module having SCART-compatible connector parts. The module comprises
a Bluetooth receiver (4) and a converter (5). Electricity supply
comes from a separate transformer, which is connected to the 220V
supply current.
The module (2) receives signals transmitted from the mobile phone,
e.g. UMTS data terminal equipment, using the Bluetooth accessory
and converts signals according to all types of different devices
from each manufacturer, image signals into RGB-signals and sound
signal parts into sound signals required by the TV.
More precisely the method according to the invention is characterized
in that, the mobile phone (1) receives sound and image information
from the mobile phone network and by pressing a certain soft key
button the phone copies image information and control information
from the display to the Bluetooth transmitter and unites sound information
to those. Former takes place according to different types of phones
from each manufacturer. After that the phone transmits it by Bluetooth
transceiver equipment to an analog TV-receiver nearby (3), in which
a module (2) is mounted. In addition to the actual converter part,
the module comprises a receiving Bluetooth accessory, which receives
image and sound transmitted by the mobile phone, e.g. UMTS data
terminal equipment, and converts these to RGB-control signals and
sound. This takes place according to different types of phones from
each manufacturer. The Bluetooth receiver in the module is connected
to a converter by using connection consistent with USB-standard.
Substantial advantages are achieved through this invention.
The invention enables that mobile phone, e.g. UMTS, CDMA, etc.,
will be used because of the new services much more than today, also
in home usage. Viewing internet-pages, if there is no PC for home
usage, can be done more consumer friendly through the already existing
analog TV.
Furthermore, home usage of video phone is enabled through television
screen and sound, for example when using UMTS at home, one can watch
his/her dialog partner more clearly through a bigger TV-screen.
Also a video received with the mobile phone can be watched through
TV, when e.g. watching a movie turns out better and a satisfactory
volume can be achieved.
Playing games received from a mobile phone network gets easier
by using a TV-screen. Altogether watching bigger images from TV
in spare time compared to a mobile phone display creates ease in
use.
Signaling Explanation:
The patent does not respond to the mobile phone function regarding
to the radio network and thus does not intervene to the part of
signaling where the radio network base station and mobile phone
transmit and receive internationally agreed radio network signals.
The patent does neither respond to Bluetooth signaling, which adhere
to internationally agreed signals.
The patent does neither respond to USB-signaling, which is based
on international specifications.
Connection Explanation:
The mobile phone, e.g. UMTS data terminal equipment, connection
is based on manufacturers methods and the patent does not respond
to that.
The Bluetooth receiver connection to the converter is based on
USB 1.1 specification or to a newer version.
The converter, which is based on signal processing, can process
with USB-signaling and controlling with the Bluetooth part and converts
image and sound information transmitted from the mobile phone to
signals (RGB+sound) required by TV.
The module connection to TV
The module is connected physically and mechanically to the SCART-connector
in the television.
