11 TA Document , December 15, 2003 IEEE1394 Interface Implementation Guideline D-VHS Device Definitions 3.1 Conformance levels expected: A key word used to describe the behavior of the hardware or software in the design models assumed by this Specification. Other hardware and software design models may also be implemented may: A key word that indicates flexibility of choice with no implied preference shall: A key word indicating a mandatory requirement. Designers are required to implement all such mandatory requirements should: A key word indicating flexibility of choice with a strongly preferred alternative. Equivalent to the phrase is recommended reserved fields: A set of bits within a data structure that are defined in this specification as reserved, and are not otherwise used. Implementations of this specification shall zero these fields. Future revisions of this specification, however, may define their usage reserved values: A set of values for a field that are defined in this specification as reserved, and are not otherwise used. Implementations of this specification shall not generate these values for the field. Future revisions of this specification, however, may define their usage. NOTE The IEEE is investigating whether the may, shall, should and possibly expected terms will be formally defined by IEEE. If and when this occurs, draft editors should obtain their conformance definitions from the latest IEEE style document. 3.2 Glossary of terms Internal Timer Event: The event registered for Timer Recording by D-VHS itself External Timer Event: The event registered on the Bulletin Board of D-VHS for Timer Recording by other controller devices than D-VHS itself on the bus EE mode: The condition of D-VHS where the input signal selection of D-VHS is set to the internal analog tuner subunit or the external input plug VV mode: The condition of D-VHS where it is in playback for representing the tape signal Power off mode: The condition of D-VHS where its power switch is turned off but the AC power source is provided. In this condition, D-VHS can communicate with other devices through 1394 interface Mechanism Initialization: The condition of D-VHS where its transport mechanism is transit to the stop position from any other position for initializing when the AC power source is connected Power on reset: The condition of D-VHS where its CSRs are initialized by modifying when the AC power source is connected.

12 IEEE1394 Interface Implementation Guideline D-VHS Device 1.0 TA Document , December 15, System Overview 4.1 Subunit Configuration The subunit configuration of D-VHS which complies with this guideline is shown in Figure 4-1. In this guideline, implementation of both Tape Recorder/Player Subunit and Bulletin Board Subunit are mandatory. Implementation of Tuner Subunit for UV analogue broadcasting system is optional. When the tuner for UV analogue broadcasting system is included in D-VHS, Tuner Subunit for that system shall be implemented according to the following rule. Rule: Tuner Subunit shall be included in the subunit_type field of response frame returned to SUBUNIT INFO status command (referred to ). Implementation of AV/C commands addressed to this Tuner Subunit is optional. When those commands are supported, they shall be implemented according to the rules defined in chapter 6 in this guideline. D-VHS Unit Tape Recorder/Player Subunit (Mandatory) Bulletin Board Subunit (Mandatory) Tuner Subunit (UV) (If UV tuner is included, the implementation of subunit is mandatory, and that of AV/C commands addressed to the subunit is optional. Figure 4-1 Subunits configuration of D-VHS The implementation of each Subunit is described in the following chapter. 4.2 The outline of Unit Operation Mode This section describes several Unit operation modes and the state transition among the unit operation modes. Refer to the section 8.2 for detail information. Page 12 Copyright 2004, 1394 Trade Association. All rights reserved.

Timer Stand-by state ( where the power state is Power off ) The condition where the Timer Event is ready to begin. (Some models do not distinguish the Timer Stand-by state from the Usual state. In those models, Timer Stand-by state is also recognized as the Usual state.) - Timer mode is changed from ON into OFF. - No Timer Event is reserved when Execution of Timer Event ended. - Accept ed Power off command issued by other controllers when No Timer Event is reserved. - Internal Timer Event has begun. - Accept ed Power on command issued by other controllers. - Execution of Timer Event ends while The reserved Timer Event remains. - Accept ed Power off command issued by other controllers when the reserved Timer Event is remained.

14 IEEE1394 Interface Implementation Guideline D-VHS Device 1.0 TA Document , December 15, 2003 The condition of D-VHS shall be satisfied, as the cassette shall be loaded when the transition occurs. The reservation for Internal Timer Event shall be rejected in each condition as follows, while the tape transport is running, and during power off state. When the reserved Timer Event data is modified in Usual state, D-VHS shall return to the Timer Stand-by state after modification is completed. The basic behaviors caused by AV/C control commands, user operation, and timer mode operation in each Unit operation mode are shown in Table 4-1. REJECTED response should not be returned to a status command in any Unit operation modes, and STABLE response should be basically returned. Timer mode cannot be changed by any command through 1394 interface. In the mechanism initialization state, it depends on each vendor whether operations through 1394 interface is available. If it is not available in that state, D-VHS cannot be recognized on the 1394 bus as a node.
