Abstract
The mode for displaying a received electronic programme guide (EPG) is automatically set by parsing or analysing a datastream (Step 20) containing programme guide information. The type of programme guide present is then determined (Step 22) and the display mode is set accordingly (Steps 24a or 24b). As shown, a schedule parser determines the whether the EPG is a 'schedule' EPG (Figure 1A) or a 'present/following' type EPG (Figure 1B), depending on the value (1 or 0) of a schedule flag contained in the bitstream. The method removes the need for the user to manually set the EPG mode, and automatically adjusts the display mode should the television service provider change EPG broadcast mode.
Description
2344953 METHOD FOR AUTOMATICALLY SETTING A DISPLAY MODE CORRESPONDING TO A
PROGRAMME GUIDE TYPE The present invention relates to a method for automatically setting a display mode in correspondence to a currently provided programme guide type in a digital TV receiver, and more particularly, to a method for automatically setting a display mode in correspondence to 11" whether a provided electronic programme guide (EPIG) type is a schedule EPG type or a present/following EPG type.
A digital broadcasting system which is being currently standardized multiplexes at least one broadcast programme into a bitstream, based on the MPEG-2 standard transport stream (TS). Also, the digital broadcasting system transmits the multiplexed bitstream to a receiver using a ground wave broadcasting medium, a satellite broadcasting medium, a cable broadcasting medium or a medium incorporating the preceding media. A digital broadcasting receiver demultiplexes the bitstream received from a transmitter and separates and reproduces a particular programme to be viewed. The digital broadcasting system transmits a bitstream to which programme guide information about channels and times of programmes to be broadcast is added, to thereby enable users to easily select a programme to be broadcast via a particular channel among a plurality of channels.
In general programme guide information provided ir. a digital broadcasting system is called an EPG. EPGs are largely divided into a schedule type EPG (or a full EPG) and a present /following type EPG (or a now/next EPG). The 2 schedule zype EPG provides programme gu'de 'Lnfor-na.iion by channels and times for a certain period of time, e. a., seven or fourteen days, which is chiefly adopted in a DTV s-,;stem in the U. S. A., the Republic of Korea, etc,. T h e present/f --!-'owing:ype EPG provides cnly presen. and next programme guide -nforma-,--Jlon by each channe., chief'1y adopted _n a DT-TV system in Europe, etc. Display to ll.e schedule EPG and r,cdes respectively corresponding _ the ore sent/ ff c Llowing EPO will be described wth. reference rring to Eigure 1A. in the case to -igures IA and 1B. Refeof a display mode corresponding to the schedule type E-PG, the transmitted schedule E7PG -'nformation is displayed --n a screen in which the schedule EPG information is contained in a graphic chart, whose vertical axis is sectioned by channels and whose horizontal axis is sectioned by times each n proportion to the length of a broadcasting time cl programme. Referring to Eigure 1B, in the case c' a display mode corresponding to the present/ following EPG, the transmitted present/following EPO information is displayed on a screen in which the present/following EPG information is contained in a graphic chart whose vertical axis is sectioned by channels and whose horizontal axis is sectioned into present programme title areas and following programme title areas.
Conventional type digital broadcasting receivers set the EPG display mode of a corresponding system into one of the above-descr-ibed EPG display modes, in advance. A-Iso, the d-a-i--a-' broadcasting receiver displays the programme guide information extracted from the received bitstream on the screen as a predezermined EPG display mode. TInu s, when an EPG type provided from a transmitter and a predetermined EPG display mode in the broadcastina 3 receiver are different from each other, the programme guide information cannot be displayed on the screen or configuration of the picture is transformed. In more detail, if a digital broadcasting receiver which has been set as the present /following EPG display mode in advance receives programme guide information of the schedule EPO type, the received information cannot be displayed on the screen. Conversely, if a digital broadcasting receiver which has been set as the schedule EPG display mode in advance receives programme guide information of the present/following EPG type, the configuration of the graphic chart to be displayed on the screen goes wrong.
th view to solve t a or reduce the above problems, the Wit digital broadcasting receiver supports the above two EPG display modes and at the same time adopts a menu setting method via a user interface. In this case, the user should manipulate a menu and check which type (s) of EPG are provided as needed, which causes a considerable 20 inconvenience in use. Also, if a respectively different EPG type is provided by channels or times in the same region, a user cannot see easily which type of the EPG is currently provided, which causes a confusion in use. As an example, since the BBC have decided to adopt a seven25 day schedule EPG recently, there may co-exist a schedule EPG type and a present/ following EPG type. As such, in the case that a broadcasting service provider changes the EPG type, the digital broadcasting receiver adopting the above-described types cannot set a display mode 30 automatically for adaption to the changed EPG type.
With a view to solve or reduce the problems above, t is an aim of ernbodiments of the present invention to 4 a method 'or automatJcally setting a -JJsplay mode prov- -L - -- -L corresponding to a programme guide type provided from a broadcasting channel which is being currently received in a d-,cit-al broadcast-Lng receiver.
According = a first aspect of the invention, there is orovided a method for automat -Lcally setting a d-'splay mode -'ded programme guide corresponding to a prov. -ype in a digital broadcasting receiver, the automatic d.,'-splay mode set ting method comprising: a) parsing a bitstream least one programme and discriminating a containl-ng at programme guide type of the programme guide contained in the bitstream; and (b) setting a display mode corresponding to the discriminated programme guide type as a display mode of the received programme guide information.
Preferably, said step (a) parses a table included in the bitstream and containing service information provided from a transmitter, and discriminates a providing type of the programme guide information.
said table containing the service information i S preferably a service description table.
Said programme guide type may be divided into a first type for providing programme guide information by channels and times for a certain period of time with respect to programmes and contained in said bitstream, and a second type for providing present programme guide information and -h -ion by each channel wit. next programme guide -n-format. respect to the programmes.
Preferably, said display mode corresponding t o tn e first type is a type for displaying a graphic chart wh--se vertical axis is sectioned by channels and whose horizontal axis is sectioned by times in proportion to a broadcasting time length of each programme on the screen, and wherein said display mode corresponding to the second.ype is a mode for displaying a graphic chart whose vertical axis is sectioned by channels and whcse horizontal axis is sectioned into two areas on the screen.
Said first type may be a schedule EPG type and said second type a present/following EPG type.
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which:
Figure 1A shows a graphic chart configured in correspondence to a screen appearance of a schedule type EPG on a screen; Figure 1B shows a graphic chart configured in correspondence to a screen appearance of a present/following type EPG; and Figure 2 is a flowchart view for explaining an automatic display mode setting method in correspondence to a provided programme guide type according to a pref-er-red embodiment of the present invention.
A variety of digital standards are being currently standardized according to countries and transmission 6 media. Most dig-,al broadeasi ng standards relate to -ransmission standards for di--ital br--adeas,:-ng Which adopt an MPEG-2 transport stream (TS) standard. Since the detailed descript-on of the MPIEG-2 TS standard is known to one skilled in the art, Oniv the portions d-Jrect'y relating to aspects of the present -nven.t--on will be ibed briefl,,; helow. The MIPEG-2 TS standard prov- desc--.
programme spe..ficatior. information;PS--) for demultiplexing a plurality of programmes mu-tiplexed into 0 one bitstream. The PSI includes at least two tables, that is, a programnie association table,PAT) and a programme map table (PM--,'. The PAT enables an identification of a PMT corresponding tO each p r c g r amme contained in a multiDlexed bitstream. The PMT enables an identification of a TS packet corresponding to each basic stream, e. q. a video stream, an audio stream or a data stream, for each programme. The PAT and PMT contain programme specification information which is necessarily required
J'or selecting a part-cular programme among a plurality of programmes contained in a received bitstream, respectively.
T n addition to the tables for the above-described programme specifcation information, the bitstream of the digital brcadcasting system can -further include tables containing various service information (S!) provided by a broadcasting service provider. If the above-described PAT ID) of nackets and PMT are c'hecked, packet identifiers (P1 containing the service information tables are checked. As 3 00 an example, the service information tables are a service description table (SDT), and an event information table (EIT) containing programme guide information designated by the service description table and according to channe's and t ime s 01the programmes. Thus, the dig-'L-al broadcasting receiver parses the PAT, PMT, SDT, and E1171 among the received bitstream and extracts the programme gu-'de information transmitted from the transmitter.
Re-ferring to Figure 2 which shows a preferred C embodiment of the present invention, a method for discriminating a programme guide type provided by a broadcasting service provider and automatically setting a mode in correspondence to the dil-scrimina--ed programme guide type in a digital broadcasting receiver, will be described. The flow-chart of Figure 2 explains 'that for the case of the programme guide information being transmitted as an EPG, data enabling an identification of a programme guide type is contained in a SDT, and the programme guide information is contained in an EIT.
Referring to Figure 2, a stream parser (not shown) in a digital broadcasting receiver parses a PAT and a PMT contained in a received bitstream to find a SDT, and parses the found SDT (step 20). The SDT contains identification data which enables an identification of a currently provided EPG type. For example, in the case that L_ identification data is comprised of a flag bit identifying a schedule EPG and a present /f ollowina EPC-1 provided by a broadcasting service provider, the identification data enables an identification of which one is the currently provided EPG type among the two EPO types. The stream parser first checks whether a schedule- flag bit configuring identification data is "1" (sten 22). If the schedule-flag bit is "1" in step 22, the currently provided EPG type is a schedule EPG. Accordingly, a controller (not shown) sets a display mode of the 8 p r -, g r amme q u i d e - n f c r ma: -i o=. a s a s c n e,-t.- -L e EEP G d i sp.1 a y mo d e;st-ec) '4a Mear.wh e, i f t h e s--'.,eciule-flag bit is " 0 i n th e :,,ec!<e- -es,,i lt o L' tlte step 2.2, t- -- ------ntly prc,,,ided E.E PC- schedule tvpe 7i vp e not- a -1.cc)rdinQly, i i S c,r-,ec.<ed w.-iet'.,ier a:)resent bitconf If - t.n e:) r e s e n t --J-ntif--ja 'or-. data is -G ow i l a g bi t is " 1 7, th e re s.J lt c f -he che c k inc 13 7 s - ep th e cu r r e n. t 1 v Q v i J e d 'i type -5 a TDresent-fcIlowing type EPIG. Accordi,-.jly, the controller (not shown) sets a displa-v, mode in --he programme guide inormation as a present-following E-PG display mode 'step 24b). Therefore, a display mode corresponding to a currently served EPG type is automatically set in a digital broadcasting receiver.
The stream parser (not shown) extracts programme guide information such as a schedule EPG or present-fol" owing EPG contained in the EIT, and supplies the extracted result to the controller. in the case that a display mode is set as a schedule EPG disQ- ', ay mode in step 24a, the ccntrcl-ler restores the schedule EPG data supplied from the stream parser into the state kept before being compressed, and contains the restored data in the eTraphic chart shown in Figure!A, so as to control the graphic chart to be displayed on the screen. in the case that a display mode is set as a present /f ollowi ng EPG display mode in s±er) 24b, the control-'---- restores t-e present/following EPG data supplied from the stream parser into the state kept before being compressed, and contains -he restored data in the graphic chart shown in Fig 1B, so as to control the graphic chart to be displayed on the 9 screen.
Thus, broadcasting receivers according to embodiments of the Dresent invention can display the received 5 programme guide information in a corresponding display mode or. the screen automatically. Accordingly, the user need not check which type of programme guide information s currently provided, thereby remarkably increasing E a broadcasting service convenLence in use. Also, even i.1L --,0 provider changes a programme guide information providing:ype, the present invention enables a digital broadcasting receiver to adaptively countermeasure thereto.
