Channel Tuning (Command: m a) G To tune channel to following physical/major/minor number Transmission [m][a][ ][Set ID][ ][Data0][ ][Data1][ ][Data2][ ][Data3][ ] [Data4][ ][Data5][Cr] Data 0: Physical channel number (Transmit by Hexadecimal code) * NTSC air: 02 ~ 45 NTSC cable: 01, 0E ~ 7D ATSC air: 01 ~ 45 ATSC cable: 01 ~ 87 Data 1, 2: Major channel number(two part) or channel number(One part) * Data1: High byte Data2: Low byte Two part channel number: Major number-Minor number One part channel number: If the channel band is ATSC digital cable, it can be used. In case of using one part channel number, minor channel does not need. Data 3, 4: Minor Channel Number * Data3: High byte * Data4: Low byte 5: Attribute 7 Main/Sub 6 Two/One 5 Picture Part Channel 0 Main 0 Two 0 1 Sub 1 One 1 Using Physical Channel Use No Use 4 3 2 1 0 Step Reser ved x 0 0 0 0 NTSC Air x 0 0 0 1 NTSC Cable x 0 0 1 0 ATSC Air x 0 0 1 1 ATSC cable_std x 0 1 0 0 ATSC cable_hrc x 0 1 0 1 ATSC cable_irc x 0 1 1 0 ATSC cable auto x 0 1 1 1 Reserved x x x x x... x 1 1 1 1 Reserved *Two/One part Channel: 6th bit This bit is used in a cable-ready system. *Using physical channel: 5th bit If the channel band is NTSC air or NTSC cable, channel tuning can be done by only physical channel. In this case, using physical channel bit must be low(0). But if the channel band is ATSC air or ATSC cable, there are two cases that physical channel enable or disable. If the physical channel sending is meaningful, you should set this bit low(0). If the physical channel sending is meaningless, you should set this bit high(1). Example) 1. Analog channel: NTSC cable, channel number(35), main picture Command: ma 00 23 xx xx xx xx 01 attribute(0x01): main picture, two part(it's not mandatory), using physical channel, NTSC cable 'xx' data: don't care major and minor channel number in case analog channel tuning 2. Digital channel: ATSC air, channel number(don't know physical channel, major(30), minor(3)), sub picture Command: ma 00 xx 00 1E 00 03 A2 attribute(0xA2): sub picture, two part, not using physical channel, ATSC air 'xx' data: don't care analog channel number in case digital channel tuning. 3. Digital channel: ATSC air, channel number(physical(20), major(30), minor(3)), sub picture Command: ma 00 14 00 1E 00 03 82 attribute(0x82): sub picture, two part, using physical channel, ATSC air Acknowledgement [a][ ][Set ID][ ][OK][Data0][Data1][Data2][Data3][Data4][Data5][x] [a][ ][Set ID][ ][NG][Data0][x] 22. Channel Add/Del (Command: m b) G To add and delete the channels Transmission [m][b][ ][Set ID][ ][Data][Cr] Data 0: Channel Delete 1: Channel Add Acknowledgement [b][ ][Set ID][ ][OK][Data][x] [b][ ][Set ID][ ][NG][Data][x] 23.
