**** BEGIN LOGGING AT Fri Mar 14 02:59:57 2008 Mar 14 11:22:49 * Yuv422 wonders how long a channel name can be? Mar 14 11:30:10 ETSI defines most textual descriptors to have an 8bit stringlength value, however the descriptor length is often also an 8bit field. So, that means the max length will be somewhere under 255 characters. Mar 14 11:30:36 Hey Peter Mar 14 11:30:40 righto Mar 14 11:31:01 could you get a duplicate lcn in the service list? Mar 14 11:31:26 I'm writing an app to modify the channel names in the svc.dat file Mar 14 11:31:28 How much under will depend on a number of encapsulation factors, but a static buffer of char[255] should be sufficient. Mar 14 11:31:54 I might just match on onid,tsid and svcid Mar 14 11:31:57 yes, duplicate LCNs are not only possible, but likely. Mar 14 11:32:05 ok Mar 14 11:32:41 I've still got a bit of the svc.dat file to decipher. Mar 14 11:33:12 the full address of a service is a concatenation of the onid, tsid, svcid (for a 48bit value) Mar 14 11:33:49 once you deal with EPG, the full address of an event becomes a 64-bit value, consisting of onid, tsid, svcid and eventid Mar 14 11:34:21 are eventid's cyclic? Mar 14 11:35:40 do you think the wiz would be more stable if they moved the wizfx functionality into wizdvp? Mar 14 11:36:45 There is no requirement for any particular allocation policy on eventids. Each service has 16 bits worth of eventids to use as required. Reusing an eventid should update any stored entries for that eventid, but that's about it as far as the specification is concerned. Mar 14 11:38:13 more than enough for the now and next style epg then ;-) Mar 14 11:38:45 Correctly dealing with the EIT data is a bit of an hit-n-miss affair, mainly because broadcasters have their own ideas that do not necessarily align with the ideas of receiver manufacturers. Mar 14 11:40:31 I've done a fair bit of work in this area, developing the technology for IceTV in such a way that it was suitable for DVB based devices as well as other "clueless" platforms, such as PCs/Media Centers. Mar 14 11:42:16 I haven't really looked into wizpimp Mar 14 11:42:27 I think that having separate executables for various subsystems would increase stability. It all runs in the same address space, so it makes no difference in terms of memory protection. Mar 14 11:43:03 and I guess memory fragmentation is handled by bank0 Mar 14 11:44:23 I would not bother with WizPimp at this stage. Last time I checked, IceTV had a lot of work to do to make it good and as far as I know, they have not been putting all that much effort into pimp. Mar 14 11:44:57 ah k Mar 14 11:45:49 Concept is good, protocol is flexible (but closed), but it needs development. Mar 14 11:46:01 I'll probably add file support to wizremote next Mar 14 11:46:04 On both server and client sides. Mar 14 11:46:09 after my svc name changer Mar 14 11:46:17 is a new beta out yet? Mar 14 11:46:25 not yet Mar 14 11:46:28 I have not had time to visit the forums in the last day or two Mar 14 11:46:47 It's still in my head at the moment Mar 14 11:47:04 I need to find out how to calculate the duration too Mar 14 11:47:13 I haven't looked into that yet Mar 14 11:47:51 I'll probably have list,delete and rename functions Mar 14 12:06:39 I'm off now Mar 14 12:06:40 cya **** ENDING LOGGING AT Sat Mar 15 02:59:56 2008
