Claim 0:
1. A method of receiving a recovery file format, the method comprising:
receiving a recovery data table;
wherein the recovery data table includes:
(a) a thisComponent element describing a media component embedded with a watermark containing a VP1 payload containing a serverCode and an intervalCode,
wherein the VP1 payload is a specific arrangement of a 50-bit VP1 payload, and
the thisComponent element includes a componentDescription element, wherein the componentDescription element includes:
(i) a component anchor element, wherein the component anchor element includes an intervalCodeAnchor element, a PresentationTime element, and a PresentationTimeMs element,
wherein a format of the intervalCodeAnchor element is an Interval Code to be used as an anchor for a presentation time,
wherein a format of the PresentationTime element is the presentation time in seconds corresponding to the IntervalCodeAnchor element as a least-significant 32 bits of a count of the number of seconds, and
wherein a format of the PresentationTimeMs element is milliseconds offset from a time indicated in the PresentationTime element, and
(ii) a mediatype element, wherein the mediatype element defines by three values indicating an audio component, a video component and the serverCode and the intervalCode are present in both audio and video component;

(b) a queryspread element expressing a maximum duration that a receiver is recommended to delay submission of a dynamic event HTTP request, in units of 1 millisecond, and having a cardinality of 0 . . . 1;
(c) an otherComponent element describing another watermarked media component, and having a cardinality of 0 . . . N;
(d) a contentID element identfying a content identifier, and having a cardinality of 0 . . . N, wherein the contentID element includes a type element being preferably required when the ContentId element is included;
(e) a sourceID element, describing an attributable distribution source that employs ATSC emission specifications, and having a cardinality of 0 . . . 1,
wherein the sourceID element is applicable to circumstances where a watermarked content is included in a redistribution of a service that is broadcast in accordance with ATSC specifications, and
the sourceID element includes;
(i) a country element describing a country code associated with a primary administrative entity,
(ii) a majorChannelNo element describing a major channel number assigned to an ATSC distribution source, wherein the majorChannelNo element is an integer number in a range of 1 to 999,
(iii) a minorChannelNo element describing a minor channel number assigned to the ATSC distribution source, wherein the minorChannelNo element is an integer number in a range of 1 to 999, and
(iv) a svclnetUrl element in a case that the svclnetUrl element is present; wherein the svclnetUrl element includes a URLValue element describing URL to access Internet signaling files; and

decoding at least one element of the recovery data table.
