2 DV Guideline 1.0 TA Document , December 15, Trade Association Specifications are developed within Working Groups of the 1394 Trade Association, a non-profit industry association devoted to the promotion of and growth of the market for IEEE 1394-compliant products. Participants in working groups serve voluntarily and without compensation from the Trade Association. Most participants represent member organizations of the 1394 Trade Association. The specifications developed within the working groups represent a consensus of the expertise represented by the participants. Use of a 1394 Trade Association Specification is wholly voluntary. The existence of a 1394 Trade Association Specification is not meant to imply that there are not other ways to produce, test, measure, purchase, market or provide other goods and services related to the scope of the 1394 Trade Association Specification. Furthermore, the viewpoint expressed at the time a specification is accepted and issued is subject to change brought about through developments in the state of the art and comments received from users of the specification. Users are cautioned to check to determine that they have the latest revision of any 1394 Trade Association Specification. Comments for revision of 1394 Trade Association Specifications are welcome from any interested party, regardless of membership affiliation with the 1394 Trade Association. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally, questions may arise about the meaning of specifications in relationship to specific applications. When the need for interpretations is brought to the attention of the 1394 Trade Association, the Association will initiate action to prepare appropriate responses. Comments on specifications and requests for interpretations should be addressed to: Editor, 1394 Trade Association 1111 South Main Street, Suite 100 Grapevine, TX USA 1394 Trade Association Specifications are adopted by the 1394 Trade Association without regard to patents which may exist on articles, materials or processes or to other proprietary intellectual property which may exist within a specification. Adoption of a specification by the 1394 Trade Association does not assume any liability to any patent owner or any obligation whatsoever to those parties who rely on the specification documents.

12 DV Guideline 1.0 TA Document , December 15, Overview 4.1 What is DV device? A device that has a Tape Recorder/Player Subunit and supports SD format (incl. SDL format) is called a DV device (e.g. Tape Recorder/Player Subunit + Tuner Subunit + SD format support). Unit Tape Recorder/Player Subunit SD/SDL format Other Subunit Figure 4-1 Subunit structure of DV device A DV device that consists of at least one Tape Recorder/Player Subunit and one Camera Subunit and supports SD format (incl. SDL format) is called a DV camera recorder (e.g. Tape Recorder/Player Subunit + Camera Subunit + Camera Storage Subunit + SD format support). The DV device consisting of Camera Subunit does not mean it implement Camera Subunit command, but it returns responses including Camera Subunit to SUBUNIT INFO status command, UNIT INFO status command, and CONNECT AV status command. Unit Tape Recorder/Player Subunit SD/SDL format Camera Subunit Other Subunit (Camera Storage etc) Figure 4-2 Subunit structure of DV Camera recorder DV devices except DV Camera Recorder are called DV decks (e.g. Tape Recorder/Player Subunit +Tuner Subunit + SD format support).

Camera Subunit, Camera Storage Subunit as well as other Subunit commands are outside the scope of this guideline. The explanations are based on [R6], [R7] Last priority The following AV/C control commands are basically applied to the last priority. Whether the DV device shares the command queue with other commands is vendor-dependent. ABSOLUTE TRACK NUMBER control command BACKWARD control command FORWARD control command PLAY control command RECORD control command WIND control command Figure 4-4 shows the example behavior of last priority.

15 TA Document , December 15, 2003 DV Guideline Implementation of Tape Recorder/Player Subunit This chapter describes the implementation of Tape Recorder/Player subunit on DV devices. 5.1 Implementation of AV/C commands This section describes the conditions for selecting AV/C responses and the target s behavior of command execution for each Tape Recorder/Player subunit commands Support Levels of AV/C commands Table 5.1, Table 5.2, Table 5.3 and Table 5.4 show the support levels of Tape Recorder/Player Subunit commands defined in this guideline. Specific inquiry commands and General inquiry commands are not described in these tables because the detailed implementations of those commands are specified in [R6]. In these tables, M means Mandatory, and O means Option. M commands are AV/C commands whose implementations are described in this guideline, and all DV devices shall implement these commands in principle. O commands are AV/C commands whose implementations are also described in this guideline, but DV devices do not have to support these commands. - means that this command is optional or not defined, and implementations of these commands are not described in this guideline.

The DV device is NOT in VTR mode (e.g. camera mode, DSC mode, memory mode, etc). No tape is inserted. Search is unavailable due to some mechanical troubles. And DV devices may return under the following conditions. Specified ATN is indicating Lead-in area. MIC is opened for read or write access. Search functionality is restricted while another interface is working (e.g. USB port is working, connected printer is running, a still picture is transferred through its serial port(232c), etc.) Current transport state is PLAY FORWARD PAUSE or PLAY REVERSE PAUSE, and specified ATN is indicating the current tape position. DV devices may not return ACCEPTED before returning INTERIM first. Do nothing Except for the above, always returns INTERIM. Starts to search the specified position. Specified position is found. Changes its transport state to PLAY FORWARD PAUSE. Searching became unavailable before finding the specified position due to factors such as key input by user, acceptance of the AV/C command which conflicts with searching, detection of the beginning of the tape and mechanism lock.
