Description
The application is that application number is 98124647.8, the applying date is on September 29th, 1998, denomination of invention is divided an application for the application of " data consistency checkout gear, data match judging apparatus and data device for sorting ".
Technical field
The present invention relates to a kind of data consistency checkout gear, data match judging apparatus and data device for sorting, particularly relate to check by the received data of broadcasting or from the numerical data of recording equipment output receivable to the whether consistent device of data with alternate data, and the device of only picking out consistent data.
Background technology
In recent years, more and more with numerical data to the occasion that image, sound or other data transmit, store.In this case, generally all be earlier data to be cut apart, formation has the data of packets of information of the data structure that is made of several fields and so on, transmits storage again; Further, on a transmission medium, carry out demultiplexing, and transmit storage after a plurality of data configuration information bags.As data structure in this case, the standard specification of demultiplexing, existing is the mpeg system standard.In most cases, all be the transmission storage of carrying out data with the method for the packet data structure of abideing by this standard.
Be carried out in the system of demultiplexing at this packet data, must in the machine that receives data, from the packet data of demultiplexing, pick out the data that should receive.Particularly to repeat according to the data mode of so-called " section " to transmit attached to the various information on the program of PSI (Program Specific Information) or SI (information on services) and so on.But, can promptly select the situation of which program etc. different because of the state of receiver as the information of necessity, therefore, must from a plurality of information, select necessary information exactly.
Below, as the example of prior art, the demultiplexer of selecting that carries out data in the receiver that uses digital broadcasting according to the data multiplex mode of mpeg system standard and so on is described.
Section is made of the zone header and the sector data of 8 bytes of the kind of the expression data of being stored etc., judges the section of whether storing necessary data by the information in the section header of test zone.
In existing demultiplexer, with processor selecting of section carried out routine processes, the storage of sectors of selecting object in memory.Processor is read the zone header part in order in memory, and it and the parameter of each byte that expression is set in the zone header that should select in the memory are compared, and judges whether unanimity.Simultaneously, the kind of the section that should select may be more than 32 kinds, and processor compares with the zone header of being imported the parameter of the candidate of representing them in order, if the parameter unanimity just is considered as necessary section to this section.
But, the problem below in the section that carries out with existing processor is selected, existing.
Carry out when section selects at processor, roughly require to possess following performance: processor is wanted to carry out 32 bit arithmetics, once can carry out the comparison of the data and the parameter of 4 bytes.When the comparison of the data of 4 bytes and parameter, indicate not carry out the comparison that every field reads parameter parameter mask information read with comparison operation result's preservation must 4 clock pulse.Comparing with 32 kinds of populations of parameters, and existing under the situation of consistent parameter, just selecting this section.If consider to have the processor of the clock of 40M VAX Instructions Per Second VAX processing speed, consider from the data transfer rate of digital broadcasting etc., storing each packets of information of several segments and just must handle with about 1000 clock pulse.
When relatively a byte number is taken as 8 bytes, selects a necessary maximum clock umber of pulse of section and be:
4 clock pulse * (8 bytes/4 bytes) * 32 kinds=256 clock pulse
That is to say, can not carry out selecting of 4 sections per 1 packets of information.In addition, the data processing of packets of information is not only selecting of section, so can not use 1000 clock pulse.
For example, in the digital broadcasting of Japan, because a packets of information maximum can transmit 10 sections, so when carrying out the selection of section with original processor, disposal ability is just not enough.
Therefore, consider the candidate of selecting is limited to below 32 kinds, to remedy the deficiency of disposal ability.
But, limit the candidate select and just mean the situation that necessary section might take place once can not pick out, in this case, select certain section after, also to select other section.In this way, till the information of selecting and obtain whole necessity, just must spend, use the answer speed of operation of machine of receiver etc. of digital broadcasting of this information just slow than the time of growing.
