Abstract
The invention provides a method for searching channel of digital televisions, which is suitable for the technical field of digital televisions. The method comprises the following steps of: S100. searching the information of a main frequency point; and S200. searching program information according to the information of the main frequency point. In the method, the information of the main frequency point is searched, and then the program information is searched according to the information of the main frequency point, thus, under the condition that each cable TV network operator adopts different program listing sequences and hide methods, the method also can search programs according to the information of the main frequency point so as to effectively search channels.
Description
Technical field
The invention belongs to the digital television techniques field, relate in particular to a kind of channel search method of Digital Television.
Background technology
At present, Digital Television is promoted just throughout the country, finally can substitute simulated television gradually.But, reason owing to historical and national conditions, the digital-TV operator in each city and area does not enter this field under monolithic standard, the mode of each operator's transmission digital television signal is also incomplete same, the PSI of Digital Television (Program service information, program service information) and the placement frequency of SI (Serviceinformation, information on services) and organizational form also may be different.
With regard to the ordering of the rendition list, can only put a programs in the bandwidth of a channel of simulated television, its possible sortord is to arrange from small to large according to physical channel, analog television program is just arranged in proper order according to this; And frequency of Digital Television can be placed multiple programs, and the sortord of the corresponding the rendition list of these programs is all defined voluntarily by each operator, and the rendition list sortord of receiving terminal only is fit to some operators.
With regard to program is hidden, operator tends to some programs that is about to play are piloted, and also locate the program in the stage of piloting for these, operator has done the processing that is different from general program technically, the shielding condition of these programs is all defined voluntarily by each operator, corresponding set-top box manufacturer and digital TV integrated machine manufacturer are at the technical specification of this operator these programs that deshield, and the final product of making equally only is fit to some operators.
Digital TV integrated machine is the market that orients towards the whole country, and sell by the retail market, therefore, when product is sold to different cities, different regions, in the face of domestic last hundred tame cable TV network operators, different the rendition list orderings of each cable TV network and the method for hiding can't be adapted to, also just platform can't be effectively searched.
Therefore, be necessary to provide a kind of channel search method of Digital Television.
Summary of the invention
The object of the present invention is to provide a kind of Digital Television channel search method, be intended to solve in the prior art, the method that Virtual network operator adopts different the rendition list orderings and hides can't effectively be searched the platform problem.
The present invention is achieved in that a kind of channel search method of Digital Television, and this method comprises: step S100, search main frequency point information; Step S200 is according to main frequency point information search programme information.
In the channel search method of this Digital Television, the main frequency point information among the step S100 comprises NIT and BAT information; Among the step S200, programme information is the information of SDT/PAT/PMT/EIT table.
In this method, step S100 comprises the steps: that specifically 105. filter the NIT table; 106. judge the NIT table whether data are arranged; If have, change step 108, otherwise change step 107; 107. judge whether filtration NIT data are overtime; If change step 113, otherwise change step 106; 108. resolve and storage NIT table; 109. filter the BAT table; 110. judge the BAT table whether data are arranged; If have, change step 112, otherwise change step 111; 111. judge whether filtration BAT data are overtime; If change step 113, otherwise change step 110; 112. resolve and storage BAT; 113. switch to next frequency.
In addition, comprise the steps: also before the step 105 that 101. start the Digital Television program search; Search the platform relevant parameter 102. be provided with; 103. judge whether frequency locking; If change step 105, otherwise change step 104;
104. judge whether frequency locking is overtime; If change step 113, otherwise change step 103.
In the step 102, relevant parameter comprises initial frequency; Digital Television is decided to be initial frequency to 99000KHz, sets parameter at Turner and demodulator.
Step S100 comprises the steps: that specifically 202. judge whether frequency locking; If step 204 is changeed in the frequency locking success, otherwise change step 203; 203. judge whether frequency locking is overtime; If overtime, change step 206, otherwise change step 204; 204. filter the SDT/PAT/PMT/EIT table; 205. programs stored information; 206. switch to next frequency; 207. judge whether next frequency is effective; If effectively, change step 202, otherwise change step 208; 208. finish to search platform.Programme information in the step 205 is the information in the SDT/PAT/PMT/EIT table in the step 204.
In addition, also comprise that step 201. setting searches the platform relevant parameter before the step 202; This parameter comprises initial frequency.
This method is by at first searching for the dominant frequency point, according to dominant frequency point search programme information, like this, adopt in each cable TV network operator under the situation of different the rendition list orderings and hidden method then, also can search program, thereby effectively search platform according to main frequency point information.
