TV PCI & USB cards ... Teletext question?
Hi,
A friend is thinking about getting a TV PCI card or preferably an external receiver, which interfaces via the USB port. He is particularly interested in viewing share prices, and needs a system which would store the sub-pages for rapid recall. I've seen a report on TV cards in August's 2007 PCW magazine, but IIRC there was little mention of teletext, let alone storing sub-pages. I get the impression that teletext is now being side-lined by the internet. Unfortunately, my friend doesn't want to put his computer on line :-( I would be very interested to hear if any one has any experience of using these devices and could recommend hardware/software combinations. TIA Clive G3CWV Hitchin, North Herts. |

I bought it secondhand from Ebay, it also has DVI output which matches my monitor. Fred. ex G6ZRU |

This could perform constant updating and full page and sub-page caching, etc. - even to the extent of permitting direct linking and embedding (DLE / OLE) - e.g. into an Excel spreadsheet, etc. As I say, this is in respect of their product line of old - confirm specifications for current generation - and I have always been markedly aware of typical or historical inferiority of USB devices vs. PCI and understand or may have some reason to believe this can, tends or is likely to relate equally to teletext aspects. However, this is may not be the case with newer generation equipment. In any event, what you suggest should, at least in theory, be quite or perfectly possible - subject to selecting the right hardware (again - ebay may not be such a bad idea - old style Hauppauge WinTV PCI cards can be had for £5 / £10 that are known to be able to do essentially what you want). Further important note: this is talking about genuine "Teletext" analogue service. If you are talking about digital text services - I cannot comment. Hence, one also needs to be aware of this being a completely different matter and the fact that the analogue service in its entirety is being switched off completely in a matter of a year or two. Best wishes, News Reader P.s. The financial service coverage on teletext really is pretty good for what it is - but at the same time - is, in reality, (a little) "pants". E.g. when delayed 15 minutes (as it is).. is "instant" sub-page recall really so useful or important? Anyhoo... your friend could always have a completely separate machine for on-line share price data, and then connect that by a totally safe method - e.g. serial cable, to his work machine - if he is concerned with or by online security or issues. That way the whole online system is completely isolated from everything else he does and his other computers, etc. - i.e. the only connection is a serial data line cable - transferring only share price data (numbers and letters) and with no capacity to do anything else or cause or be any other risk. Again, just one example. |

(pedants should stick there heads where the sun never shines. I know all text is digital). In fact on the BBC the share price pages doen't even appear to have page numbers.

The message
from g6zru contains these words: I have a ATI All In Wonder Card. It replaces the video card and the later one have full teletext support.

Regarding the ATI card, is there any software to enhance the performance of the teletext system, such as storing pages and/or sub pages. Can the text be transferred to other programs, ie. editors & spreadsheets? Is it compatible with the new digital TV? Cheers Clive |

As I say, this is in respect of their product line of old - confirm specifications for current generation I'll have a look at the specifications. However, I find that it's often difficult to get detailed information about these high-tek products, without buying them first :-( In any event, what you suggest should, at least in theory, be quite or perfectly possible - subject to selecting the right hardware Some years ago, I did write some software for capturing pages data from a BBC teletext adapter. I had some success, but found the transmission system very very complicated. IIRC the data was transmitted in small packets, all interleaved, instead of being sent as a continuous string of text. Further important note: this is talking about genuine "Teletext" analogue service. If you are talking about digital text services - I cannot comment. He currently looks at the analogue teletext, as this displays more share prices than the digital equivalent. There are about 200 - 300 shares on analogue, but only about 400 on digital. Hence, one also needs to be aware of this being a completely different matter and the fact that the analogue service in its entirety is being switched off completely in a matter of a year or two. Ideally, any adapter bought now should cover both services. P.s. The financial service coverage on teletext really is pretty good for what it is - but at the same time - is, in reality, (a little) "pants". E.g. when delayed 15 minutes (as it is).. is "instant" sub-page recall really so useful or important? Yes, that's what he wants. The problem with the existing analogue system is that you often have to wait for a long time to get the wanted sub page, and then it is only displayed for a short time. Very frustrating! The teletext on digital TV seems much better for getting share price information, but I can't be sure whether this is a function of the overall system, the STB, or the broadcaster. Anyhoo... your friend could always have a completely separate machine for on-line share price data, and then connect that by a totally safe method Unfortunately, I can't persuade him to go on-line, inspite of all the advantages :-( Rather oddly I haven't been able to find an on-line service similar to the teletext. There is a complete list of 'end of day prices' available from two sources. Many sources offer single share prices or a preset portfolio delayed 15 minutes, but not a complete list. He really needs something like a trading platform, which could be quite expensive. Regards Clive |

The message
from Mark Carver contains these words: There is however an on-line (not official) portal for Ceefax: http://www.ceefax.tv/ Thanks for that. It looked good at first, but the sequence of prices on BBC1 appeared to have been overwritten by some of the pages from BBC2. Perhaps it's a neglected service, and therefore unofficial. pity it would have suited my friend, if I could persuade him to go on-line :-( Regards Clive |
