208 | Struct status_packet_format includes two common fields and other fields
|

209 | that depend on the type of the originator field of the first status_type

210 | struct. The orignator bitfield of the status_type struct can have the
|
---|
211 | following values: 0 = reserved, 1 = VideoControl interface,
|
---|
212 | 2 = VideoStreaming interface. The second common status_packet_format field
|
---|
213 | orignator includes ID of the Terminal, Unit or Interface that reports the
|
---|
214 | interrupt.
|
---|
215 | If the orginator bitfield value is 1 (VideoControl interface) then third
|
---|
216 | field of the status_packet_format is event field that includes value 0x00
|
---|
217 | for control change. Other values (0x01 - 0xFF) are reserved.
|
---|
218 | The fourth field selector reports the Control Selector of the control that
|
---|
219 | have issued the interrupt.
|
---|
220 | The fifth field attribute specifies the type of control change: 0x00 is
|
---|
221 | Control value change, 0x01 is Control info change, 0x02 is Control failure
|
---|
222 | change and values 0x03 - 0xFF are reserved.
|
---|
223 | After that can be several value fields that can include values 0x00, 0x01
|
---|
224 | and 0x02.
|
---|
225 | If the originator bitfield value is 2 (VideoStreaming interface) then
|
---|
226 | third field of the status_packet_format is event field that can have
|
---|
227 | value 0x00 (Button Press) or values 0x01 - 0xFF (Stream errors).
|
---|
228 | If event value is 0x00 (Button Press) there is only one value field. It
|
---|
229 | can include values 0x00 (Button released) or 0x01 (Button pressed). If
|
---|
230 | event value was some Stream error value, then there can be several value
|

231 | fields.
