Simultaneously, various aerial information screen prompt users, channel data grid 54 will be inserted the information about channel, and one of 64 every row, these information receive or receive that promptly, channel number is positioned at row 58 from all ground-plane antennas; Platform title (, being positioned at row 60) as NBC (if possible); This channel be the numeral or the simulation, be positioned at row 58; That day, line received this channel, was positioned at row 60; Only for digital channel, their current demand signal intensity is positioned at row 62.Information about the other types of various channels also may be shown.Channel data grid 54 comprises screen title 56 (aerial information) and has shown a plurality of row, once is five-element 64a-e at this. Arrow 67 and 68 expressions can be seen more channel by the scroll-up/down grid.
The aerial information screen was measured in the aerial information measuring process before will preserving but was not had enough intensity to come by " signal strength threshold standard/level " so that added to those channels the channel list from channel search.This is the result of expectation, because the user may not know to obtain the channel of what locality, in case but they know to obtain what channel, whether the user decides in its sole discretion and tries to regulate their antenna so that some channel has enough intensity to be added in the channel search table.
In case finished signal strength measurement, will on display 36, illustrate in the aerial information result screen shown in the program screen 44.The grid that the user can be circulated by scroll-up/down/make an inspection tour around tabulating by the various attributes of channel number and they or characteristics (row 64 and row 58,60,62) definition utilizes current aerial position can obtain what channel to check.Those digital channels that have for example one "-" rather than a number are represented signal strength signal intensity neither be large enough to watch this channel can not add this channel to channel list from channel search again, see 64d.All analog channels will show that " N/A (inapplicable) " can not picked up signal ionization meter (seeing 64c) to those channels with indication as their intensity.Those current channels that can not obtain by channel search can appear in the former signal strength measurement table or appear in the information table that obtains by guide or otherwise in this demonstration.
If the user selects " aerial information " function, the signal strength signal intensity of that channel is with measured and/or renewal so.Along with the user rolls by different channel, tuner is attempted and is connected by the channel of highlight.If this channel is detected, signal strength measurement is obtained and/or is upgraded.Whenever channel can not given up because signal strength signal intensity is not enough automatically, and this helps user to understand can to obtain what channel and tries to regulate antenna so that channel has enough signal strength signal intensities is added in the channel table.
This table can be numbered the highest channel number sorting of bottom from the lowest channel at top.Share the channel that same virtual channel is numbered for analog-and digital-channel, analog channel and digital channel are adjacent in table.
The user can be only upgrades information (seeing 64b) at each channel by move highlight to that channel in the aerial information screen.In addition, the video of back, aerial information viewing area will illustrate current channel, comprise audio frequency, carry out antenna adjustments to help the user.In order to change the input of antenna or antenna, the user can push ANTENNA (antenna) or select by menu on remote controller.When having carried out a complete aerial information search each time, the signal strength signal intensity of all digital channels is measured.The channel of each highlight is with its signal strength signal intensity real-time update in the grid, and the Voice ﹠ Video of this channel broadcasts in program screen 44 back on display 36 simultaneously.The signal strength signal intensity of each obtainable channel can not show automatically in an alternate embodiment.Signal strength signal intensity will show behind the selection channel.
When finishing the signal strength measurement process, a dialog box will be presented on the display 36, mainly be in the mode of stack or in current screen.When the user selects " Continue (continuation) ", the highlight of aerial information screen will be shifted to first channel rows (64a) in the channel data grid 54.If user's interrupt signal measuring process, a dialog box is shown notifies the user, and the intensity that shows in channel data grid 54 is determined any size before processing is interrupted.
Channel in tabulation is during by highlight (64b), continued to upgrade about the information of channel.This digital channel of router and system information protocol (PSIP) (ATSC file A/65) guide change channel arrange with one with situation that digital channel has the analog channel of identical main channel number (abbreviating main channel as) to include under be particularly useful.In this case, the aerial information tabulation will be expanded with the analog channel that this is new and include as the independent clauses and subclauses in channel data grid 54 (row 64).New analog channel will have identical channel number with digital channel, but will be labeled as analog channel in row 58, with to be labeled as digital channel relative.The renewal of this tabulation and expansion are fully automatic and real-time.
Obtain the best signal strength signal intensity of given set of number channel in order to aim at ground-plane antenna, be necessary probably the ground-plane antenna of each receiving digital television signal is carried out aerial information search several times.When antenna is positioned, the signal strength signal intensity of various digital TV channels will need with antenna direction monitored relatively.By repeatedly carrying out the aerial information search, can find the aerial position an of the best.When antenna is had good positioning, be necessary to carry out channel search so that channel is added in the channel list.
An example will be explained above-mentioned principle.Adopt the new ground-plane antenna (antenna 26 among Fig. 1) that receives aerial digital television signal to be connected to receiving system (TV12 among Fig. 1).Suppose that after power supply the initial condition of signal tabulation and aerial information tabulation all is empty.Channel search is moved by user's operation or because be added after the former channel search of several new channel during this device initial setting up the time.Initial channel search location has two channels of the signal of the given threshold level that is higher than minimum reception, i.e. channel " 10 " " 20 ".Herein, channel list comprises channel " 10 " and " 20 ", and the aerial information tabulation comprises channel " 10 " and " 20 ".So the user regulates antenna 26 and carries out another channel search.Two additional channel with signal of the given threshold level that is higher than minimum reception have been located in this search, and promptly channel " 30 " and " 40 " still do not detect former channel " 10 " and " 20 " owing to new antenna direction.Now, channel list comprises channel " 30 " and " 40 ", and the aerial information tabulation comprises channel " 10 ", " 20 ", " 30 " and " 40 ".Can obtain four channels now because the user knows, aerial information search operation is to attempt to determine the optimum position of antenna during each aerial position slight modification.To check channel " 10 " according to the program flow diagram of Fig. 5.Suppose that present channel " 10 " has a signal strength signal intensity greater than predetermined threshold.Therefore, channel " 10 " is added to channel list and makes that the content of channel list is channel " 10 ", " 30 " and " 40 ", and aerial information is itemized and do not changed.Execution is regulated and the search of another time aerial information another time of antenna.Suppose that present channel " 20 " has the signal strength signal intensity greater than predetermined threshold.Channel " 20 " is added in the channel list so that the content of channel list and aerial information tabulation all is channel " 10 ", " 20 ", " 30 " and " 40 ".
