Description

A BROADCAST RECEIVER DEVICE WITH ENHANCED SIGNAL RECEPTION EFFICIENCY

The present invention relates to a broadcast receiver device whose communication performance is enhanced by ranking data from a plurality of signal sources and selecting the most favorable source.

Digital and interactive television systems present a high number of television channels and programs, and as a result of this situation, traditional methods for making adjustments for the operation of the display device require working through many setting parameters, which consequently becomes an inefficient and time consuming effort.

Currently, due to the fact that users are presented with many television and multimedia services, it is needed to design methods for a main device, in other terms a display device such as a television set having a digital receiver-player to effectively process received services. A display device can receive programs in different membership formats by means of cable or satellite broadcasts.

Broadcast receiver devices require communication modules and in particular, antennas to connect to internet, to be adapted for remote access or to be able to receive a broadcast signal. Antennas collect the electromagnetic waves scattered in space and enable these waves to be transmitted through transmission lines (receiver antenna) or enable signals received from transmission lines to be dispersed as waves in space (transmitter antenna). Antennas are sized, shaped and are usually named according to wave lengths. When an electronic device needs to remotely connect another electronic device, it emits electromagnetic signals. The electronic device to be connected converts these waves into electrical signals by means of a receiver antenna adapted to collect electromagnetic waves in the frequency range of the wave sent, enabling connection. Receiver antennas are provided in broadcast receiver devices such as televisions, in order to remotely connect the devices and to enable broadcast data transmission.

In devices such as televisions and satellite receivers, multiple antennas are used to watch a plurality of broadcasts or to record a broadcast while watching another, and tuner circuits are used enabling inputting antenna signals to a satellite receiver or a television.

In current broadcast receiver devices, multiple antenna inputs are provided to present multiple channels and broadcast recording options to users. Such inputs are disposed on a device as MAIN and SUB antenna inputs, which are short for MAIN Antenna reflector and SUB antenna reflector. By connecting the broadcast cables to said inputs, broadcast is played through the selected connection regardless of channel signal measuring. Problems such as low signal quality or failure to display is experienced in cases when the channel to be watched by a selected connection input has a low broadcasting quality or incorrect connection of the broadcast cables to antenna inputs.

State of the art United States patent document no. US 6002672 A1 mentions a broadcast receiving system with two antennas which combines channel lists from both antennas and presents a single list to the users. A method is disclosed, in which the broadcast source of the list containing the channel selected by a user, is automatically selected for being displayed.

State of the art United States patent document no. US7421012 B1 discloses a selection method of opting for the best signal level between a plurality of Wi-Fi antennas.

The aim of the present invention is to realize a broadcast receiver device comprising a processor enabling performing between a plurality of antennas a selection with enhanced signal receiving efficiency.

The broadcast receiver device realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a body, a processor executing entered commands, a plurality of antennas enabling collecting signals from a transmitter, at least one antenna connection input enabling connecting an antenna on the body, at least one tuner enabling the signal received by means of an antenna to be processed and converted to a format suitable for displaying, a plurality of connection lines enabling data transmission between the tuner and an antenna, and a switch enabling switching between antennas on the connection lines. A user can control the broadcast receiver device by sending commands to the processor by means of a device menu. The device menu is displayable on a screen, controllable by a remote controller and enables making selections.

In the broadcast receiver device of the invention, the processor activates upon a user making a selection on the device menu, and executes the steps of sending the related selection parameters to the tuner, comparing the related broadcast signals by sequentially activating connection lines, and applying the user's selection by using the connection path determined to have the strongest signal strength between the compared signal parameters of the related selection. The broadcast signal source may be a satellite antenna, external satellite receiver or a connection via USB. The variety and high number of signal sources enables displaying a higher quality broadcast. Problems such as a decreased broadcast quality or failure to receive broadcast due to a user connecting antenna inputs incorrectly, are eliminated by dismissing the dependency of source selection from a physical antenna source connection.

In an embodiment of the invention, the broadcast receiver device comprises at least two tuners and at least two antennas. Separate connection lines are established between each tuner and each antenna. Each one of said connection lines independent of each other, convert data from a related antenna to a format suitable for displaying the broadcast, enabling options such as watching two separate broadcasts or recording a broadcast while watching another. The signal levels between antennas are compared upon a user sending the processor the information of the channel desired to be watched, and the connection line with the highest signal level is activated. When it is desired to record a channel other than the one being watched, a source can be selected according to signal level determination and ranking between the inputs other than the signal source of the channel being watched. The user is thus enabled to watch the desired broadcast with the highest quality.

In an embodiment of the invention, the broadcast receiver device comprises a processor triggered upon a user selecting a channel, and sending commands to the switch switching between connection lines. Upon a user selecting through the device menu a content desired to be watched, the processor ranks the antenna signals between the input channels of the present antenna connections providing the related content. Upon determination of the connection line with the highest signal strength, the processor commands the switch to form a new connection, making the transition from the last connection prior to the channel change to the preferred new connection. Ease of use is thus provided by making an automatic selection and executing the transition without requiring a user to control manually.

In another embodiment of the invention, the antenna enables receiving radio frequencies. The antenna may also be designed to receive Bluetooth or Wi-Fi signal frequencies. Bluetooth is the name of the short range radio frequency (RF) technology eliminating cable connection. Bluetooth enables computers, peripheral units and other devices to communicate without a cable connection even when they are out of visible reach. Bluetooth technology operates in 2.4 Ghz ISM frequency band, and is capable of sound or data transmission. The effective distance of Bluetooth enhanced devices capable of data transmission up to 24 Mbps is approximately in the range of 10 to 100 meters. This is included in the IEEE 802.15.1 Standard regulated by the IEEE (The Institute of Electrical and Electronics Engineers). Wi-Fi (Wireless Fidelity) is the technology enabling Internet connection of devices such as personal computers, Internet connected televisions, video game consoles, digital sound players and smart phones. Wi-Fi enables laptop computers, PDAs and other portable devices to connect to a nearby local area network by means of wireless access points. Such a connection is enabled in 2.4 GHz or 5 GHz radio frequency in accordance with IEEE 802.11 protocol used commonly by both the wireless access points and the devices. In cases when a media content can be displayed by means of a Bluetooth or Wi-Fi connection, the antenna provided in the device eliminates the necessity to establish a cable connection line. If a valid content source related to a viewing preference transmitted to the processor is provided, the processor performs the steps of selecting through ranking between the present sources with the highest signal strengths. The signal strengths of the sources are monitored and compared throughout the content watching period, switching the content source when a better signal level is determined, thereby providing the users with the best viewing quality throughout the watching period.

In an embodiment of the invention, a method enabling operating the broadcast receiver device is executed comprising the steps of receiving radio frequency signals by means of a plurality of antennas; transmitting these signals to the tuner via connection lines established separately between each antenna and the tuner; converting the signals to a signal frequency adapted for displaying; upon entering on the device menu of the processor an information for the channel desired to be watched, sending parameters of the related channel to the tuner; sequentially activating each connection line by commanding the switch; monitoring the signal levels on the tuner; and selecting for the determined channel the connection line with the highest signal level measured in the tuner. By this, content source is selected according to signal strength, enhancing watching quality of the user.

A broadcast receiver device is realized by means of the invention, comprising a plurality of antennas, whose watching efficiency is improved and signal level is enhanced by automatic broadcast source selection.
