The TSPlayer is able to display teletext and subtitles „on screen“ in the Video Window, if according data is included in a transport stream (TS) file. It supports the following kinds of subtitles: Teletext, DVB, ISDB, ATSC CEA 608 closed captions and BluRay (BD presentation graphics in TS and M2TS files). This chapter describes how to adjust the teletext and subtitle display to your needs.
Teletext is switched on/off by clicking the button on the Player Tab. The button opens a pop-up menu allowing to select subtitles, if available, or switch them off. Since the buttons are intended for playback and conversion control, they partly work a bit different compared to other players.
Please note: The following
settings do not apply to the “graphical” DVB and BluRay
subtitles.
Font: Selects the font for teletext as a whole and for text based subtitles (teletext, ISDB, ATSC captions).
Use Bold Font: Tick this checkbox, if you want the teletext and text based subtitles to be displayed with bold letters. If it is unticked, the broadcaster's presetting will be used, if there is any.
Automatic character set selection if possible: If this checkbox is ticked the TSPlayer tries to resolve the ambiguity of the teletext character set information by reading the language from the PMT. If available it overrides user defined preferences (see below).
Always search for ATSC captions in MPEG2: ATSC CEA 608 closed captions are embedded in the MPEG2 video stream. If this checkbox is unticked the TSPlayer will only search for the caption data if there is evidence that a TS file originates from an ATSC source. If the checkbox is ticked it will search in every MPEG2 video stream regardless of the source and file format. This is mandatory for displaying ATSC captions in MPG (program stream) files.
Subtitle Transparency: This slider adjusts the background transparency of text based subtitles (teletext, ISDB, ATSC). The leftmost position (0%) puts the broadcaster's transparency presetting in effect, if there is any. The rightmost position equals a transparency of 75%. Please note: This setting does not apply to teletext pages as a whole. They are always displayed with opaque background.
Character Set Preferences: This check-listbox lets you decide which country specific character set shall be used for teletext and teletext subtitles. Each of the sections divided by blue lines contains a group of languages specified by the national option bits that are embedded in the teletext stream. E.g. a certain bit pattern may ambiguously specify English, Polish or Serbian as language. Select the one that you want to be applied in case of doubt. Please note that one and only one item can be checked per section.
The lower part of the Teletext Tab enumerates the keys that can be used to select a teletext (sub-)page:
Ctrl [0] switches teletext display on/off.
Ctrl [0]...[8] select page 100...800.
The numeric keys [0]...[9] are used to input a page number
[←-] deletes page numbers in backward direction (backspace).
[+] and [-] switch over to the next resp. preceding page or sub-page.
Ctrl [+] and Ctrl [-] search the next / preceding page containing subtitles.
