Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
The invention discloses a kind of method of digital TV set-top box fast channel switching, it specifically comprises the following steps: described Set Top Box comprises at least one tuner, the transport stream that described tuner is corresponding all outputs to Set Top Box demultiplexing module, remote control signal receiving module receives current frequency, one of them tuner carries out frequency locking to current frequency, this tuner is set to current tuner, Master control chip controller top box demultiplexing module is exported the program decoding of current program, and other tuners carry out frequency locking near the frequency current program respectively.Tuner is that current tuner is when carrying out demodulation to current program frequency point therein, other tuner also carries out demodulation near the frequency current program frequency point simultaneously, parameters and frequency locking, in the time of user's zapping, the TS stream of next frequency has had output, directly carry out just can watching after program decoding, has saved the time of parameters, frequency locking, changing to another one platform from a platform so only needs the buffer time of 0.5 second, has strengthened user's experience.
The method flow diagram of digital TV set-top box fast channel switching of the present invention as shown in Figure 1.Be described as an example of the Set Top Box of integrated three tuners example, first via tuner is a road, and the second road tuner is b road, and Third Road tuner is c road.
Active user selects n programs to watch, the TS stream (transport stream) that demultiplexing uses is a road, the parameter that b road, c road tuner arrange respectively n+1, n-1 programs is carried out frequency locking, be no matter now user select program+, or program-, its parameter arranges already, and TS stream has had output, only need directly to select b road or c road to carry out program decoding, so just saved the time of parameters, frequency locking.When after the selected program viewing of user, two-way tuner can pass through again the program parameter up and down of the current program of programming in addition, and plays preparation.
Preferably, the quantity of described tuner is 3, and a tuner is separated timing to current frequency therein, and two other tuner respectively program of former and later two frequencies to current frequency carries out demodulation.3 tuners just can be realized goal of the invention of the present invention, can also save production cost.
Preferably, receive after zapping information at remote control signal receiving module, the frequency signal controlling Set Top Box demultiplexing module that Master control chip receives according to remote control signal receiving module is exported corresponding program decoding, corresponding tuner is set to the tuner of current output, and other tuner carries out frequency locking near the frequency current program respectively.As selected n programs to be converted to n+1 programs and to watch as user time, the TS stream that demultiplexing uses is b road, and the parameter that a road, c road tuner arrange respectively n, n+2 programs is carried out frequency locking.
Preferably, the zapping information receiving at remote control signal receiving module is for adding one or subtract in one, corresponding tuner is set to the tuner of current output, again near the frequency that there is no frequency locking current program is carried out to frequency locking from current tuner tuner farthest, the frequency locking Information invariability of other frequencies.Like this, in changing a platform, only have the frequency locking informational needs of a tuner to change at every turn, increased the speed of system operation.As selected n programs to be converted to n+1 programs and to watch as user time, the TS stream that demultiplexing uses is b road, the parameter frequency locking of the corresponding n programs of original a road tuner is constant, the parameter that is n+2 programs by the parameter modification of the corresponding n-1 programs of original c road tuner is carried out frequency locking, by that analogy, platform of every replacing only needs a tuner replacing parameter to carry out frequency locking, has increased the speed of system operation.
Preferably, when the zapping information receiving at remote control signal receiving module is the digital input table of directly selecting, the frequency signal controlling Set Top Box demultiplexing module that Master control chip receives according to remote control signal receiving module is exported corresponding program decoding, corresponding tuner is set to the tuner of current output, and other tuner carries out frequency locking to the frequency when other respectively.As user inputs x,, when user inputs x, the parameter of x-5, x+5 channel has just been arranged to idle two-way tuner on backstage, the so at utmost input of match user, and now tuner way is more, and the success rate of coupling is just larger.
The structure drawing of device of digital TV set-top box fast channel switching of the present invention as shown in Figure 2.The invention also discloses a kind of device of digital TV set-top box fast channel switching, comprise at least one tuner, Set Top Box demultiplexing module, remote control signal receiving module, Master control chip, described tuner is for carrying out frequency locking and demodulation to frequency signal, described Set Top Box demultiplexing module is for receiving the transport stream of tuner output, described remote control signal receiving module is for receiving the signal of remote controller and being transferred to Master control chip, Master control chip is for the output of controller top box demultiplexing module, the transport stream that described tuner is corresponding all outputs to Set Top Box demultiplexing module, remote control signal receiving module receives current frequency, one of them tuner carries out frequency locking to current frequency, this tuner is set to current tuner, Master control chip controller top box demultiplexing module is exported the program decoding of current program, other tuners carry out frequency locking near the frequency current program respectively.Tuner is that current tuner is when carrying out demodulation to current program frequency point therein, other tuner also carries out demodulation near the frequency current program frequency point simultaneously, parameters and frequency locking, in the time of user's zapping, the TS stream of next frequency has had output, directly carry out just can watching after program decoding, save time of parameters, frequency locking, the device of above-mentioned digital TV set-top box fast channel switching is changed to another one platform from a platform only needs the buffer time of 0.5 second, has strengthened user's experience.
