The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Waltham (Leicestershire, England) mast?

Dave Lindsay: Re: 10.48 posting, funny you should mention the procedure you were using as I did wonder, not being quite sure if you were injecting the analogue modulator into the system using a "Y" splitter in reverse as a combiner, its common leg going into the Sony and each of the other two legs being fed from the aerial and VCR respectively, although the method used by yourself certainly seemed to be quite effective by the fact of it backing up user i.d: brian's findings (20th @ 7.09pm) of singling out COM5 as being the cause of the problem.

As far as Sony taking measures to address the apparent vulnerability of these boxes to whatever data glitch had caused the problem, I have an open mind on this as to whether or not they would consider it necessary to do this, because the whole situation could simply have been caused accidentally at Arqiva's end by a glitch having occurred when COM5's EPG data was being entered, and not necessarily as a result of any purposeful act of someone having altered the data for any reason.

The other aspect being, that Sony had not carried out any software up dates immediately prior to the problem occurring nor were they involved in any way with the problem clearing up again, and so up to a point anyway it could be said that Sony was relatively blameless in this particular case as corrupted data was responsible.

I have another sneaking suspicion that this sort of thing may also have been the reason for the recent WMC fiasco that blocked the reception of Waltham's PSB2 but only when received via WMC's PC tuners, this problem like COM5's having magically cleared up in exactly the same "silent" way and with no admission of responsibility having been taken for the problem.

I tuned com5 in late yesterday and the system is still ok. It seems that the Gremlin has gone away for the moment!

I contacted both Sony and Arquiva but have had no reply so far. I'm not holding my breath!

New CRIDs for events on Pick TV, Challenge and Sky News were recently added to the DTT EIT.

Previously, all CRIDs in the DTT EIT had a data part that started with "/"; the new CRIDs did not.


The following definition has no requirement of a "/" at the start of the data part.

from ETSI TS 102 822-4 V1.7.1 (2012-12) Section 8:-

http://www.etsi.org/deliv….pdf

==============================================
The syntax of the CRID is:

CRID://<authority>/<data>

<authority> uses the TV-anytime authority naming rules given in clause 7 to assure uniqueness.

<data> is a free format string that is Uniform Resource Identifier (URI) compliant, and is meaningful to the authority given by the <authority> field.

The <data> portion of the CRID is case insensitive.

In its entirety, the CRID is URI compliant. (See RFC 3986 [1] for URI compliance specification). As per RFC 3986 [1], the CRID:// part of the syntax is case insensitive.


Example of a syntactically valid CRID:

CRID://company.com/foobar

CRID created by "company.com" authority, with a data part of "foobar".
==============================================


The following is an example of a typical event on Pick TV before and after the change:-

js: If the "crid" should, according to the specification, have a preceeding / then why was it omitted? Was it thought that it wouldn't matter? Might it have been a slip or was it just plain sloppy?

Dave Lindsay:

Well that's the question. All I have to go by is the ETSI definition in my post and that doesn't require a "/" so I think it was valid.

The equivalent Freesat data is still missing the "/" and has not caused problems as far as I know.

You mean sabotage? Possibly, but if the data was (and is) valid and only a few types of box affected, not very likely.

On the grounds of pure logic, what is the point of wasting bandwidth transmitting something that is always there?

js: The question must be one of whether the slash is required under the specification for the language.

If the answer is "no" then the broadcaster was right to use it and it appears that these boxes have a bug in their firmware/software.

If the answer is "yes" then the broadcaster was wrong not to include them.

Here's an odd thing. On the sitting room TV the freeview EPG for BBC2 @ 19:00 showed "Dad's Army", whereas the one in the bedroom showed "Swimming World Championships" at exactly the same time. They're both tuned to Waltham.

Which mux does the epg come from?

Do the digiboxes store epg data and only very occasionally refresh?

As a matter of interest, the program that actually aired was "Dad's Army".

The digibox in the bedroom is an Icecrypt T5000 (which has always worked well), and the sitting room one is Goodmans GD11FVZS1 (which has always suffered from very illogical idiosyncrasies).
