Embodiment
The present invention proposes a kind of terminal and method that can receive the mobile TV of two kinds of standards, be used for according to user's selective reception and handle CMMB (China Mobile Multimedia Broadcasting, China Mobile multimedia broadcasting) mobile TV signal or anolog TV signals.It is conceived substantially: the mobile TV chip of integrated two kinds of standards on a terminal, and two kinds of mobile TV chips are linked to each other with same mobile TV antenna by a radio-frequency (RF) switch; After selecting to activate wherein a kind of mobile TV chip according to the user, the signal exchange channels of this mobile TV chip that is activated of radio-frequency (RF) switch conducting and mobile TV antenna can be received corresponding mobile TV signal and handled like this by this mobile TV chip controls mobile TV antenna that is activated.The user can be switched between two kinds of mobile TV chips as required, thereby receives and handle the mobile TV signal of corresponding standard.
Describe the embodiment of the invention in detail below in conjunction with accompanying drawing.
With reference to figure 1, the figure shows the structure chart of the terminal of a kind of mobile TV that can receive two kinds of standards of the embodiment of the invention, comprise following assembly: electromechanics is looked antenna, a communication antenna, a radio-frequency (RF) switch, first mobile TV chip, the second mobile TV chip, the first communication process chip, second communication process chip, display module on the other hand, and control module.
Wherein the annexation of each assembly is: the mobile TV antenna links to each other with the second mobile TV chip with the first mobile TV chip respectively by the mobile TV control pin TVCC of radio-frequency (RF) switch; Communication antenna links to each other with the second communication process chip with the first communication process chip respectively by the Control on Communication pin VCC1 to VCC5 of this radio-frequency (RF) switch; Control module respectively with first mobile TV chip, the second mobile TV chip, the first communication process chip, and the second communication process chip links to each other; The first mobile TV chip and the second mobile TV chip link to each other with display module respectively.
To introduce the effect of above-mentioned each assembly in detail below:
Control module is used for receiving according to the user instruction activation first mobile TV chip or the second mobile TV chip of the mobile TV of a certain standard; And adopt the instruction of a certain communication pattern to activate the first communication process chip or second communication process chip according to the user;
The first mobile TV chip is the analogue mobile phone TV chip, is used for treatment of simulated mobile TV signal; The second mobile TV chip is a Mobile Multimedia Broadcasting mobile TV chip, is used to handle mobile multimedia broadcast television signal.Described first mobile TV chip or the described second mobile TV chip are after being activated, send the conducting control signal to described radio-frequency (RF) switch, control the signal exchange channels of this mobile TV chip that is activated of this radio-frequency (RF) switch conducting and mobile TV antenna, receive the mobile TV signal of corresponding standard by this signal exchange channels control mobile TV antenna then, and obtain the mobile TV signal that described mobile TV antenna receives and handle after send to display module.When described first mobile TV chip or the described second mobile TV chip send described conducting control signal, be that the mobile TV control pin TVCC with radio-frequency (RF) switch is changed to high level or low level.
The first communication process chip is the communication process chip of two different communication patterns with the second communication process chip, such as, can be respectively the gsm communication process chip, perhaps TD communication process chip.The first communication process chip or second communication process chip are after being activated, send the Control on Communication signal to described radio-frequency (RF) switch, control the signal exchange channels of this communication process chip that is activated of this radio-frequency (RF) switch conducting and communication antenna, receive the signal of communication of corresponding modes by this signal exchange channels control communication antenna then, and obtain the signal of communication that described communication antenna receives and handle after send to display module.When the first communication process chip or second communication process chip send described Control on Communication signal, be that the communication logic control pin VCC1 to VCC5 with radio-frequency (RF) switch is changed to high level or low level respectively.
Described radio-frequency (RF) switch is the radio-frequency (RF) switch that a hilted broadsword six is thrown, and this radio-frequency (RF) switch comprises 1 mobile TV logic control pin TVCC, and 5 communication logic control pin VCC1 to VCC5.Here it is pointed out that TVCC is the same with other VCC, represent the logic control pin, for the purpose of distinguishing, among the application TV and VCC have been defined in together, i.e. TVCC is referred to as mobile TV logic control pin on the radio-frequency (RF) switch with it.The level height of TVCC carries out set by the mobile TV chip that is activated, and the level height of VCC1 to VCC5 carries out set by the communication process chip that is activated.The mobile TV chip that this radio-frequency (RF) switch is activated by the level height conducting of judging TVCC and the signal exchange channels of mobile TV antenna, and by judging the level height of VCC1 to VCC5, the communication process chip that conducting is activated and the signal exchange channels of communication antenna.Wherein, the signal exchange channels of described communication process chip that is activated and described communication antenna also wraps and is divided into signal sendaisle and signal receive path.
This radio-frequency (RF) switch can be carried out according to table one according to the concrete operations of the judgement of each logic control pin level height being carried out the conducting of signal exchange channels, and wherein H represents high level, and L represents low level.RX represents receiving communication signal, and the TX representative sends signal of communication, and TD, GSM and DCS represent the pattern of signal of communication.For example, this radio-frequency (RF) switch judges that the level height situation of each logic control pin of TVCC, VCC1 to VCC5 is respectively: H, L, L, L, L, H, the then signal receive path of this radio-frequency (RF) switch conducting TD communication process chip and communication antenna, and the signal exchange channels of CMMB mobile TV chip and mobile TV antenna.
