Embodiment 1

[0029] figure 1 It is a flow chart of a main frequency point update method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of main frequency point update. The method can be implemented by a terminal, for example, it can be a digital TV set-top box, or it can be a built-in digital The TV set of the TV set-top box may specifically be implemented by software and / or hardware in the terminal. see figure 1 , the main frequency point update method includes the following steps:

[0030] S110. When the modulation parameter of the main frequency point is updated, determine a first frequency point that can be frequency-locked, where the first frequency point and the main frequency point belong to the same satellite.

[0031] Among them, if the terminal fails to demodulate the main frequency bit stream data according to the pre-stored main frequency point modulation parameters, it can be considered that the main frequency point modulation par...

Embodiment 2

[0046] figure 2 It is a flow chart of a main frequency update method provided by Embodiment 2 of the present invention. On the basis of the above embodiments, this embodiment specifically explains step S120, that is, how to The rule determines the frequency point information of the reference frequency point. Explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment.

[0047] see figure 2 , the main frequency point update method in this embodiment includes:

[0048] S210. When the modulation parameter of the main frequency point is updated, determine a first frequency point that can be frequency-locked, wherein the first frequency point and the main frequency point belong to the same satellite.

[0049] S220. Determine whether there is a connection descriptor whose connection type is 0x04 in the NIT of the first frequency point.

[0050] Wherein, after the first frequency point is successfully...

Embodiment 3

[0060] image 3 It is a structural schematic diagram of an apparatus for updating a main frequency point provided by Embodiment 3 of the present invention, and this embodiment is applicable to updating a main frequency point.

Abstract

The embodiment of the invention discloses a master frequency point updating method and device, a terminal and a computer readable medium. The method comprises the steps of determining a frequency lockable first frequency point when a master frequency point modulation parameter is updated, wherein the first frequency point and a master frequency point belong to the same satellite; determining frequency point information of a reference frequency point according to a network information table (NIT) of the first frequency point and a preset rule; and carrying out frequency locking on the referencefrequency point according to the frequency point information of the reference frequency point, determining the modulation parameter corresponding to a preset ONID (Original Network ID) and a TSID (Transport Stream ID) of the master frequency point according to the NIT of the first frequency point, and updating the master frequency point according to the modulation parameter. According to the master frequency point updating method and device, the terminal and the computer readable medium provided by the embodiment of the invention, the problem that a user cannot watch a program normally when the master frequency point modulation parameter is updated is solved, the user experience is improved, and the market popularization and maintenance of an operator brand are facilitated.

Description

technical field [0001] Embodiments of the present invention relate to digital television technology, and in particular to a main frequency update method, device, terminal and computer readable medium. Background technique [0002] The main frequency point in the present invention refers to the frequency point used to carry program management information in a multi-program stream (Transport Stream, TS) for digital television transmission. The modulation parameters of the main frequency point include modulation mode, modulation system, frequency, modulation rate (symbol rate), polarization mode, forward error correction (Forward Error Correction, FEC) and so on. The terminal obtains the program management information from the main frequency point, and according to the program management information and the existing main frequency point modulation parameters, it can demultiplex and recombine the multiplexed TS data packets for demodulation and sorting out each set program stre...
