The present invention relates to a television; more particularly, relates to transferring multimedia data through an indoor power line to a television to save indoor lines.
When watching programs on a wireless television or a cable television (CATV), a television 10 according to a prior art is connected with an antenna 101 or a CATV cable 102 for receiving signal data to be displayed on a screen of the television 10.
Although signal data is received by the antenna 101 or the CATV cable 102 to be displayed by the television 10, old buildings seldom leave room in advance for connecting the antenna 101 or the CATV cable 102. Therefore, general people locate their televisions at default positions while using longer signal lines extended to the outside to connect to the antenna 101 or the CATV cable 102. Not to mention if there are additional devices (such as DVD players PS2 players, MTV players, etc.), extra lines has to be used for transferring signal data in between. So, in addition to the power line, there are many complicated lines like a chaos at the back of the television.
If a building leaves room for connecting the antenna 101 or the CATV cable 102 in advance, the location for the room left is predestined. The user has to accommodate himself to its terminal for connecting to the antenna 101 or the CATV cable 102, which makes the problem happens as usual. So, the prior arts do not fulfill users' requests on actual use.
Therefore, the main purpose of the present invention is to transfer multimedia data to a television over a power frequency carrier, provided by an indoor power line, in an indoor power line; and, then, to be converted by a converter built in the television to be shown on an output display of the television, so that the multimedia data is transferred through the indoor power line to the television to be displayed and to save indoor lines.
To achieve the above purpose, the present invention is a television set having a power frequency carrier, comprising a television with an output display and an in put power source; a converter deposed in the television with a single-chip control module, a power carrier module, an output module connected to the output display, and an input module connected to the in put power source; an indoor power line connected to the input power source; and a multimedia transmittal part connected to the indoor power line.
The present invention will be better understood from the following detailed descriptions of the preferred embodiments according to the present invention, taken in conjunction with the accompanying drawings, in which
The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention.
Please refer to
The television 1 comprises electrical devices (not shown in the figures), an output display 11 and an input power source 12.
The converter is deposed in the television 1, comprising a single-chip control module 21, a power carrier module 22 with a transmission baud rate of 1200 BPS, an output module 23 connected to the output display 11, and an input module 24 connected with the input power source 12. Therein, the single-chip control module 21 comprises an input receiver 211, an output controller 212, a control module 213, a communication interface 214 and a relay 215; the control module 213 is a processor of a 8051 single-chip with a working frequency up to 16 MHz together with a 4 k size of electrically programmable and erasable ROM (Read Only Memory) together with eight input pins and eight output pins; and, the relay 215 is located at the output pins to quarantine the circuit for securing and ensuring the operation of the single-chip control module 21. The 8051 single-chip contains a full-duplex communication interface 214 inside; the communication interface 214 can be an RS232 interface to transfer and receive data simultaneously from outside. Because the operational signals are on a TTL (transistor-transistor-logic) level (0 voltage set as logic 0; +5 voltage set as logic 1) and the communication interface 214 is a serial communication interface to transfer or receive data in a form of series of bits, linkages can be easily established between two objects of controllers (such as absorbing carriers or automatic measuring devices), equipments, computers, or any combination.
The indoor power line 3 is a general indoor power source for the input power source 12 to plug in.
The multimedia transmittal part 4 is connected to the indoor power line 3, which can be a CATV cable or a cable for transmitting multimedia data from a satellite. The indoor power line 3 is connected to the input power source 12 to provide a power frequency carrier for transmitting the multimedia data to the converter 2 through the indoor power line 3. Hence, a novel television having a power frequency carrier is obtained with the above structure.

To sum up, the present invention is a television set having a power frequency carrier, where multimedia data over a power frequency carrier in an indoor power line is transferred to a converter built in a television to be converted for being displayed on an output display of the television so that multimedia data can be transferred by an indoor power line to be displayed by a television and indoor lines required can be lessened.
The preferred embodiments herein disclosed are not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
