7 TA Document , December 15, 2003 TV for Japanese BS/CS Guideline Overview 1.1 Purpose The purpose of this guideline is to clarify the IEEE1394 implementation which is not described in detail in the related AV/C command specifications and ARIB Standard. TV for BS/CS Digital Broadcasting System means a DTV which has the function to receive broadcast service of either BS digital broadcasting or CS digital broadcasting, or both. 1.2 Scope The scope of this guideline is to specify the behavior of the TV which complies with ARIB Standard for Receiver for Digital Broadcasting B (ARIB 3.1[R10]) and has a capability to decode MPEG2-TS signals, which are received from both 1394 interface and the antenna for digital broadcasting, and output the decoded signals through analogue output. This guideline specifies following functions through IEEE1394, Control of power status, and inquiry of the power status. Control of tuning, and inquiry of the tuning status. Inquiry of the input source connected to TV monitor. The function which outputs a selected service through IEEE1394 by control from external device. Following functions are optional and beyond the scope of this guideline. This guideline does not specify the behavior of following functions. The function which changes the DTV status to 1394 input state. The function which makes partial stream from MPEG2-TS stream received from the bus. The function which outputs and displays two or more services simultaneously. The function which outputs the stream from the Tuner Subunit to 1394 bus and analog output plug(s) while decoding and outputting the MPEG2-TS received from the 1394 bus. The function which outputs two or more isochronous stream simultaneously. When a DTV has supports both BS and CS broadcasting, the DTV selects one service from BS signal or CS signal. A DTV, which has capability to select both services of BS and CS simultaneously, is beyond the scope of this guideline. This guideline allows two kinds of implementations. One is based on AV/C Digital Interface Command Set, General Specification Version 4.1 (AV/C General 4.1 [R13]) and AV/C Descriptor Mechanism Specification Version 1.0 (AV/C Descriptor 1.0 [R14]). The other is based on AV/C Digital Interface Command Set, General Specification Version 3.0 (AV/C General 3.0 [R5]). Although this guideline is described based on the implementation according to AV/C General 4.1 [R13] and AV/C Descriptor 1.0 [R14], it corresponds also to implementation according to AV/C General 3.0 [R5] unless otherwise specified. The portion, that has any difference between two implementations, is described expressly with the version number applied. Copyright 2004, 1394 Trade Association. All rights reserved. Page 7

10 TV for Japanese BS/CS Guideline 1.0 TA Document , December 15, System Overview 4.1 Subunit Configuration The Subunits configuration of TV for BS/CS digital broadcasting system which complies with this guideline is shown in Figure 4-1. In this guideline, implementation of Tuner Subunit for BS/CS digital broadcasting system and Monitor Subunit are mandatory. Although implementation of Bulletin Board Subunit is optional, this guideline recommends implementing Bulletin Board Subunit because other device can not detect the reservation confliction without Bulletin Board Subunit. Although implementation of Tuner Subunit for UV analog broadcasting system is optional, refer to chapter 6 about the implementation method if implemented. DTV Unit for BS/CS digital broadcasting system Tuner Subunit (for BS/CS digital broadcasting system) Tuner Subunit (for UV analog broadcasting system) Monitor Subunit Bulletin Board Subunit Figure 4-1 Subunits configuration of DTV for BS/CS digital broadcasting system The implementation of Unit and each Subunit are described in the following chapter. 4.2 Operation Mode of Unit This section describes several Unit operation modes and the state transition between the unit modes. The outline of the state transition of DTV, which has the function of record-reservation and view reservation, is shown in Figure 4-2. In this guideline, the definitions of Record-reservation and Viewreservation are described below, and these reservations are called internal reservation. Record-reservation: Reservation made by DTV itself, which is to record specified program(s) using recording device outside the DTV at the specified date and time. At the starting time of the Record reservation, DTV select the specified program and control the recording device to record the program. If the DTV is power off state at the starting time, it changes its power state to on, and executes above mentioned control. Page 10 Copyright 2004, 1394 Trade Association. All rights reserved.

11 TA Document , December 15, 2003 TV for Japanese BS/CS Guideline 1.0 View-reservation: Reservation made by DTV itself, which is to view specified program(s) at the specified date and time. At the starting time of the View reservation, DTV select the specified program. It is vender dependent whether the DTV has the functions of Recording-reservation and/or Viewreservation. When it does not have these functions, the transitions to the state of reservation execution in Figure 4-2 are not performed. On the other hand, the reservation registered in the Bulletin Board Subunit of DTV from external device is called external reservation in this guideline. The state controlled by external device during the period of external reservation is called external reservation execution. It is vendor dependent whether the DTV distinguish the state external reservation execution from the state of usual power on state and has some restrictions of its operation. (Note that Figure 4-2 has no distinctions). In case of the DTV is power off state, the DTV is under one of tow power off states called i.link standby" and "i.link not standby". The definition of each state is as follows. i.link standby: The state where the DTV is existing on 1394 bus as a node and where it can receive AV/C commands. i.link non standby: The state where the DTV is not existing on 1394 bus as a node, or the state where it can not receive AV/C commands although the device is existing on 1394 bus as a node (repeater state). The selection of i.link standby or i.link non standby is possible only by manual operation of the DTV during power on state by the user. The selection can not be done by the AV/C commands via 1394 bus. Note that a DTV that is in the repeater state may change its state to "i.link standby" state by receiving Link-on packet.

It is vender dependent to permit this transition. *4) Although the transition is possible only during View-reservation execution, it is vender dependent to permit this transition itself. *5) Although this transition can be made only when the state is "Power off" at the time of starting view-reservation, it is vendor dependent to permit this transition. *6) In the case of finishing view-reservation, when the state was "Power off" at the time of starting view-reservation, the state is transitioned to "Power off" or "Usual power on state". As shown in Figure 4-2, the power state of Unit and Tuner Subunit is always the same. Therefore, when one of the power states of Unit or Tuner Subunit is changed by POWER control command, the other power state shall be changed by the internal operation. The basic behaviors caused by user operation and AV/C control commands in each Unit operation mode are shown in Table 4-1.

15 TA Document , December 15, 2003 TV for Japanese BS/CS Guideline Implementation of Tuner Subunit for BS/CS Digital Broadcasting The TV for BS/CS digital broadcasting system complies with this guideline shall implement Tuner Subunit for BS/CS digital broadcasting system according to Supplement to IEEE1394 Interface Implementation Guideline, Tuner Subunit for Japanese BS/CS Digital Broadcasting System[R15]. In addition, The Tuner Subunit shall also be implemented according to the rules described in this chapter. 5.1 POWER Control Command In this guideline, the following rules are added to the rules described in Supplement to IEEE1394 Interface Implementation Guideline, Tuner Subunit for Japanese BS/CS Digital Broadcasting System[R15] regarding the behavior of the POWER control command. Rule When the target returns the ACCEPTED response for POWER control command and changes the power state of Tuner Subunit, it shall change the power state of Unit simultaneously by internal operation. In the model described in Figure 4-1 of this guideline, the power state of Unit and Tuner Subunit are always the same by applying above described rule. For details, refer to Section 4.2.

16 TV for Japanese BS/CS Guideline 1.0 TA Document , December 15, Implementation of Tuner Subunit for UV Analog Broadcasting In case a TV has a built-in tuner for UV analog broadcasting, there are three ways to implement Tuner Subunit. Implementation 1. Implementation with support of Subunit commands Implementation should conform to the specification in Supplement to IEEE1394 Interface Implementation Guideline, Tuner Subunit for UV Analog Broadcasting System [R16]. Implementation 2. Implementation without support of Subunit commands Since commands addressed to the Subunit are not supported, any control (tuning etc ) or getting status of tuner by AV/C commands is impossible. With the notification of the existence of this Subunit by SUBUNIT INFO command, a controller can know correct internal connection by CONNECT status command. Implementation 3. Implementation with substitution by external input plug Not showing the existence of Subunit by SUBUNIT INFO command. That is, a controller cannot recognize the existence of the tuner for analog broadcasting. In this implementation, Tuner Subunit pretends to receive the signal from external input plug during the use of UV analog tuner (refer to for details). Page 16 Copyright 2004, 1394 Trade Association.

17 TA Document , December 15, 2003 TV for Japanese BS/CS Guideline Implementation of Monitor Subunit 7.1 Implementation of Plug In this guideline, Monitor Subunit shall implement at least one input plug (destination plug) as input for a main screen of TV monitor, and this input plug is assigned to 0 as the plug number. 7.2 AV/C Commands This section describes the list of Monitor Subunit AV/C commands supported by the DTV and implementation of each command Support Levels of AV/C Commands Table 7-1 shows the support levels of Monitor Subunit commands specified in this guideline and 1394TA Std. Although Subunit Identifier Descriptor is specified in 1394TA Std, this guideline treats the support of descriptor as option and does not specify the implementation. The shaded portion in the table means optional or recommended commands to which this guideline does not specify any rules. Since the behavior of Specific inquiry and General inquiry command is specified in AV/C General 4.1[R13], description is omitted here.

The case where the implementation method is 3, it becomes a state which is same for input to be from the analog input terminal. The DTV has an external antenna input plug (antenna input for BS/CS digital broadcasting system), an external antenna input plug (antenna input for UV analog broadcasting system), a serial bus input plug, one or more external input plug as inputs of the device and a serial bus output plug and one or more external output plugs as outputs of the device. The number of external input/output plugs depends on a device, and this guideline does not specify it. Moreover, when a DTV physically has two or more analog output terminals, these terminals may be logically regarded and implemented as a single external output plug unless the signal source of these terminals can not be changed independently. As for analog input terminals, the number of physical terminals can be different from that of external input plug. Page 22 Copyright 2004, 1394 Trade Association. All rights reserved.

23 TA Document , December 15, 2003 TV for Japanese BS/CS Guideline 1.0 The external input plug (antenna input for BS/CS digital broadcasting system) is a plug which inputs the signal received from the antenna to Unit, and is connected with the antenna destination plug of the Tuner Subunit for BS/CS digital broadcasting system. Antenna input for UV analog broadcasting system (external antenna input plug) is a plug which inputs the signal received from the antenna to Unit, and is connected with the antenna destination plug of the Tuner Subunit for UV analog broadcasting system. The serial bus input plug is a plug which receives the MPEG stream from 1394 bus to Unit. The function that makes partial stream from the received stream is optional, and this guideline does not define it. As for received stream from the 1394, this guideline defines the function that decodes the stream as is, and output the analog signal. DTV may have the digital/monitor-separate-operation-mode. In this operation mode, DTV executes two functionalities simultaneously. One is output the stream tuned by the Tuner Subunit to 1394 bus. Another is displaying the signal from other than Tuner Subunit for BS/CS digital broadcasting system (ex input signal or the signal from Tuner Subunit for UV analog) on Monitor Subunit. In this operation mode, SW1 in Figure 9-1 selects a source plug of tuner subunit, and SW3 selects the other signal source. Thus, SW2 is interlocked with one of SW1 and SW3 when SW1 and SW3 select different signal. It is vendor dependent which SW2 is interlocked with. If digital/monitor-separate-operation-mode is canceled, SW1,2 and 3 select the same signal source. This guideline does not specify which to select between SW1 and SW3 as the same input source. When DTV with digital/monitor-separate-operation-mode is not in the operation mode or a DTV does not have the operation mode, SW1, 2 and 3 are interlocked with one another and the signal source of serial bus output plug, external output plug and Monitor Subunit are always the same. The behavior of SW1, 2 and 3 is specified as follows, and the control of SW1, 2 and 3 by CONNECT control command is optional. Behavior of SW1: SW1 selects source plug of the Tuner Subunit for BS/CS digital broadcasting system while DTV receives the BS/CS digital broadcasting signal from the air. SW1 selects source plug of the Tuner Subunit for UV analog broadcasting system while DTV receives the UV analog broadcasting signal from the air. SW1 selects external input plug of the Unit while DTV receives the analog input signal. SW1 selects serial bus input plug of Unit while DTV decodes the stream from this serial bus input plug. While SW1 selects a plug other than the source plug of the Tuner Subunit for BS/CS digital broadcasting system, the serial bus output plug may not output the stream corresponding to signal source. If a DTV receives DSIT control command addressed to Tuner Subunit for BS/CS digital broadcasting system and accepts the command while SW1 selects a plug other than the source plug of the Tuner Subunit for BS/CS digital broadcasting system, the connection state of SW1 shall automatically be changed to select the source plug of the Tuner Subunit. Behavior of SW2: SW2 is interlocked with SW1 and 3 while the DTV is not in the digital/monitor-separateoperation-mode. This guideline does not specify with which SW2 is interlocked while the DTV is in the digital/monitor-separate-operation-mode. Behavior of SW3: SW3 is interlocked with SW1 and 2 while the DTV is not in the digital/monitor-separateoperation-mode. SW3 selects the different source from SW1 while the DTV is in the digital/monitor-separate-operation-mode. If a DTV receives DSIT control command addressed to Copyright 2004, 1394 Trade Association.

This guideline uses the value complying with ARIB 3.1[R10]. 9C16 is recommended as the value of antenna input plug for UV analog broadcasting system. Note: Some former models use 8016 for the value of antenna input plug of UV analog broadcasting system In this guideline, the external input/output plug numbers are assigned to ascending order from The Table 9-1 uses the number of external input/output plugs described in Figure 9-1 as an example. 9.2 AV/C Command This section describes the list of Unit commands supported by the DTV and implementation method of each command Support Levels of AV/C Commands Table 9-2 shows the support levels of Unit commands specified in this guideline and 1394TA Std.
