But be only suitable for and be configured for the switching of carrying out from a program to other programs in identical standard at this this known method and receiving system thereof.In other words, described receiving system be only configured to receive by the first reflector analog/digital the program, for example ZDF that send.If vehicle changes in a region, in this region, this program is no longer sent by reflector with identical standard, can be in identical standard, but can not in another standard, receive this program ZDF.
Standard be characterised in that it there is different reception parameters, as modulation, codec that coding, Voice & Video were used.For every kind of standard, conventionally need to independently receive hardware, described reception hardware forms a reception approach together.This means, each reception approach (prospect, background) has independently hardware for every kind of standard.Now different reception hardware group is synthesized a reception approach.
Term " service is followed " refers to such method, the method make user can be even across place follow selected service." service " refers to program (for example, at German ARD, ZDF etc., at China, Japanese CCTV1, NHK etc. and similar program).To this, television receiver automatically changes receive frequency and attempts, and the program of setting is provided to user with best quality all the time.The method is known and be applicable to mobile receiver and realize with multiple by DE10 2,005 039 507A1.The method adversely only limits to single standard.
Summary of the invention
The object of the invention is to, provide a kind of for receiving the method for the high-frequency signal of mobile television reception, described method is improved with respect to prior art.
This object realizes by feature claimed in claim 1.
According to the present invention, set, by the receivable program of described at least one other RX path, as the alternative of the program for broadcasting, in alternative list, show, wherein, if select the alternative of the program that can receive with described at least one other standard, by the first RX path be tuned to described other standard.By the method according to this invention and the receiving system of structure correspondingly, can on the place of corresponding vehicle, in programme, first show the program of being selected by operator, its hope is watched.Simultaneously by the first RX path, it is for receiving, process and the device of display, be tuned on this program, to can show described program.Simultaneously also that by reflector, sent, identical but there is the program of other standards by means of the second RX path search of same relative configurations in background.If alternative being identified in this program that should the broadcast standard different from the program just in time using shows described program in alternative list.Thus can be for example when the sound quality of television image and/or receiver declines, select best alternative and automatically prospect reception approach is adjusted and be tuned in new standard.
In other words novel part is, across study plot, uses reflector to follow the tracks of.To this television receiver (being all hardware of each RX path), must can receive, assess and play used receivable standard in other words.
Only have when television receiver has at least two to receive approach, just can carry out following the tracks of across the reflector of a plurality of standards.Two described approach are commonly referred to prospect approach and background approach.By prospect approach, broadcast the program (service) of current setting.By background approach, always programme is remained in up-to-date standard.The method is designed to mobile use occasion, because the reception condition of program changes constantly.
Abbreviation and definition:
In improvement project of the present invention, set, for each can have an alternative list by program receiving deposit, wherein, this alternative information singly comprising about the parallel program providing of all energy, described program can receive by identical or different standard, and described identical or different standard sends identical content.To the operator of vehicle, provide operator's programme that can therefrom select, that there is receivable program and the alternative list that can use for described receivable program at any time thus.
When receiving area is overlapping, often occur, identical program is repeatedly received.Described program is conventionally on other channels (frequency).But in the visible programme of client, described program is but only registered once.Due to this reason, each program has an alternative list.All identical programs in this alternative list, have been gathered.
Which by means of described alternative list, can know all the time, at the upper meaningful identical program of other channels (frequency).At this, it is unimportant which kind of standard these programs belong to.Important only, these programs have identical content.
In improvement project of the present invention, by the second RX path, upgrade constantly the alternative list of each program.Such advantage is, for you to choose alternative of the program that broadcasting is provided at any time.
In order to carry out having rational reflector to follow the tracks of between various criterion, to an alternative list of each program (service) storage.This alternative information that walks abreast and provide, send the program of identical content about all that singly comprises.
Described alternative list upgrades by background approach equally constantly.
In improvement project of the present invention, set, if find new program by the background search of carrying out by means of the second RX path, in the programme of current existence, check, whether there is the program that content is identical, if there is the program that content is identical in programme, newfound program is registered in the alternative list of the programme under the program that just will broadcast.Such advantage is, can broadcast constantly the program that will broadcast and therewith concurrently by identical emerging but can add to the program of other standards sending and receiving in alternative list.
If search for (background approach) by background, find in the programme of current existence, to check new service whether had the program that content is identical.If meaningful identical program in programme, by newfound service registration in the alternative list of this program.
In improvement project of the present invention, monitor constantly the program of current reception, and, by means of the program that will broadcast can be predetermined criterion, and when the parameter that can predetermine surpasses the threshold value that cocoa predetermines, the program that will play receiving with a described standard is switched to the identical program receiving with another standard.
There is the multiple possibility that gathers the service with identical content.By gathering the service of various criterion, saved the comparison to the different table of standard.Described comparison can only be used within identical standard in reflector is followed the tracks of.
In improvement project of the present invention, set, if the parameter that can predetermine surpasses the threshold value setting that can predetermine, content program identical, that receive with a described standard is switched to content program identical, that receive with another standard.
In the reflector of various criterion is followed the tracks of, use relatively following:
-comparison service name
-comparison EPG information
-television text the information that relatively exists
For coherent as far as possible error-free image is provided to user, must monitor constantly the service of current setting.According to used standard, provide specific parameter:
-level
-the error rate
-packet loss
These parameters are recycled and assess.They indicate, and whether the program of current setting is also worth receives.By the distinctive calculating of parameter, also can assess the process of reception.Now according to the correct threshold value force handoff of setting, arrive on the program (alternative service) that content is identical.
To the monitoring of alternative service, must equally cyclically in background, carry out.This same use and parameter identical when monitoring current service.At this, be also defined as the threshold value that service must be surmounted as real alternative use.
Alternative in order to be switched to, must meet the following conditions:
1. the service of current setting is no longer worth receiving.
2. must there is alternative service, by means of background monitoring, select described service alternative as what will use.
If two conditions all meet, cause inner modulation process.At this, which kind of standard new service belongs to is unessential.
