Walt, Your idea about the book indexing seems plausible except for one thing: The BP may jump back by several sentences, but then when I stop continuous reading mode and then use the 3 key to go forward by a sentence (well, not always a sentence in a DAISY book, but the smallest movement possible), movement will be by smaller amounts than by the amount the BP jumped back. Thus, if we use the indexing model, it seems that the BP jumps back by several index marks during these events. To me, this sounds like some kind of buffering problem - i.e., how much data is sent to the speech chip at once and where it can start again. Don't know but it is a little strange. Is this clear? -- Pete From: "Walt Smith" <walt@xxxxxxxxxx> Subject: [bookport] Re: Latest Beta and File Position Date: Sat, 11 Feb 2006 14:28:56 -0500 Peter - This, in various forms, has been around as long as I've owned a BP and that's going on eighteen months now. I've determined from experimentation that it has something to do with the index markers in the book, itself, as I've had some files where this would only cause a backward skip of perhaps a sentence and others of the same format where the file would go back over a page. I haven't actually experimented much with different formats, but I know that I've seen it in .txt, .brf, and DAISY files. I've become convinced, though, that it's not so much a BP problem as a file formatting problem. ----- Original Message ----- From: "Peter Torpey" <ptorpey@xxxxxxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Friday, February 10, 2006 9:51 PM Subject: [bookport] Latest Beta and File Position Here is a behavior I am seeing in the latest beta which I have not observed before (or at least not as badly). 1. I am listening to a book ("Catch Me If You Can") which I downloaded from Bookshare in DAISY format onto my Bookport. Actually, I transferred it to the Bookport before updating to the BP Transfer beta which I installed today (Friday). 2. While in continuous reading mode, I will hit one of the keys to adjust speech rate or volume. 3. The BP suddenly will skip back several sentences and continue reading from a prior position in the book. Now I know that some stuff probably gets caught in the buffer, but I've been surprised at how far back the BP is jumping. I seem to feel that in the past, such a jump would only occur possibly to the previous sentence. Note, I don't think the jump is to a previous marking in the DAISY text since, if I stop the BP after the jump, I can hit the 3 key (while reading is stopped) to advance several sentences before I am at the position I was before hitting one of the speech rate or volume keys. 4. I am seeing a similar behavior if I stop reading - i.e., when I start again I can sometimes be several sentences back from where I had stopped (not just one sentence). Just curious if something changed or this is a particular attribute of how this book was originally marked. -- Pete
