CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a Divisional Application of U.S. application Ser. No. 10/016,828, filed on Dec. 4, 2001, and is a continuation of and claims the benefit of priority to International Application No. PCT/GB01/01458, filed on Mar. 30, 2001 and from the prior British Patent Application Nos. 0008436.8 filed on Apr. 5, 2000, 0008426.9 filed on Apr. 5, 2000, and 0008398.0 filed on Apr. 5, 2000. The entire contents of each of these documents are incorporated herein by reference. FIELD OF THE INVENTION [0002] A first aspect of the present invention relates to identifying video and/or audio and/or data material. [0003] A second aspect of the present invention relates to digital video tape recording. [0004] A third aspect of the present invention relates to recording apparatus and methods of recording audio and/or video information signals. More particularly the third aspect relates to recording apparatus and methods of recording audio and/or video information signals onto a linear recording medium. Correspondingly, the third aspect also relates to reproducing apparatus and methods of reproducing audio and/or video information signals and in particular information signals recorded onto a linear recording medium. [0005] Material, which may be any one or more of audio, video and data, is represented by information signals which are preferably digital signals. [0006] First Aspect of the Invention. [0007] Description of the Prior Art [0008] It has been proposed to identify video and/or audio material and/or data using UMIDs which are identifiers which universally uniquely identify material. UMIDs in principle could identify video material to the accuracy of one frame. There is a basic UMID and an extended UMID. A basic UMID has 32 bytes each of 8 bits and an extended UMID has 64 bytes. It may be possible in some circumstances to use a reduced data structure UMID where for instance some data of a plurality of UMIDs is common to the plurality of UMIDs. [0009] It is clearly desirable to associate the identifiers as closely as possible with the material which they identify and most preferably include the identifiers in the material or in the case of material recorded on a recording medium record the identifiers on the medium. However, there is little or no spare data capacity in some media, especially tape. In addition it is desirable to record other data such as Good Shot Markers (GSMs) on the medium with the material. Thus other desirable data competes for space on the media. [0010] Summary of the First Aspect of the Invention. [0011] According to the present invention, there is provided a video, audio and/or data signal processing system comprising a recorder for recording video and/or audio and/or data material on a recording medium the recorder including a first generator for generating first material identifiers for identifying respective pieces of material on the medium such that each piece is differentiated from other pieces on the medium, and a second generator for generating second, universally unique, identifiers for pieces of material, second identifiers being generated in respect of one or more of the first identifiers. [0012] A second identifier may be generated for each of the first identifiers. A second identifier may be generated in respect of a group of two or more first identifiers. [0013] The first identifiers, which need to distinguish the pieces of material on the medium, but need not be universally unique, can thus be smaller than universally unique identifiers. For example the first identifiers may comprise only two bytes. That is sufficient to allow the second generator to generate the second identifiers. Also, it minimises the amount of data which need be stored on the medium to identify material thereon allowing other data, e.g. Good Shot Markers, to be recorded. [0014] In preferred embodiments, a medium identifier is provided which identifies the medium. It is for example a serial number. The second generator generates the second identifiers in dependence on the medium identifier and the first identifiers of the material on the medium. [0015] In another embodiment, the medium is housed in a housing supporting a data store. The data store preferably stores the medium identifier and may also store at least one of the first identifiers. Most preferably the first identifiers are recorded on the medium and the store stores only the last produced of the first identifiers to enable the first generator to produce the first identifiers in a regulated manner. [0016] The use of the first identifiers or of the first identifiers plus medium identifiers which may be placed on the medium and/or in the data store allows existing record medium formats especially tape formats to use the identifiers and be incorporated in a production and distribution system which uses universally unique identifiers such as UMIDs and metadata bases. Existing tape formats can accommodate the first identifiers and tape cassettes having data stores are in current use (at the application date of this application). [0017] The embodiments of the invention address the problem of labelling tapes and other recording media by providing the medium identifier. The use of short first identifiers allows GSMs to be recorded. The data store is not essential but can be used if available. [0018] These and other aspects and advantages of the first aspect of the invention are set out in the following description of FIGS. 1 to 30. [0019] Second Aspect of the Invention [0020] Description of the Prior Art. [0021] Several formats of digital video tape have been proposed. The first commercially successful format was the so-called "D1" format, described in the book, "Introduction to the 4:2:2 Digital Video Tape Recorder", Gregory, Pentech Press, 1988. Since then there have been many other formats, either standardised or proprietary. [0022] A feature that these formats have in common is the use of helical scanning. This is a well-established technique in which the tape medium is wrapped at least part of the way around a head drum. One or more rotating read/write heads, mounted on the head drum, sweep out successive slant tracks on the tape medium as the medium is progressed slowly past the head drum. Slant tracks may carry a timecode known in some systems as Vertical Interval Timecode (VITC). Linear tracks may also be used to carry information such as Linear Timecode (LTC), other control information, a cueing audio track and the like. Continue reading...
