SonyPhilips Digital Interconnect Format (S.’PDIFI input to a different SPDIF inputi. This bit may be used by the Listener to adjust quickly to thc new media clock. This kind of changc need not be seamless but allows the Listener to Lake any appropriate action to minimize the disruption to the stream.
This bit is toggled by the Tnlkcr each time a media clock restart is needed, and it stays at its new value until a new media clock restart is needed. This toggle ensures the media dock restart will not be missed if it were to appear in a single AVTPDU that just happens to be dropped. Once this bit toggles. it must remain in its new state for a minimum of eight AVTPDUs f a given stream.
5.4.2 r: (reserved) field
The reserved bit field (r) is a I bit field reserved for future use in stream data AVTPDLI headers.
This field is act to zero (0) on transmit and ignored on receive.
5.4.3 gv: (gateway_info field valid) field
The gatewr s_info field vahd (gv) field is reserved for use by AVTP gateways that are no; defined by this standard.
AVTP end stations that do not have an AVTP gateway function shall set this field to zero (0) on transmit and ignore this field on receive.
5.4.4 tv: (avtp_timestamp_valld) field
The avtp_timestamp_valid (Ii) field is a I bit field used to indicate the validity of the astp_limeslamp field time value.
If the avptimestarnp_valid bit is set to zero (0) by the AVTP Talker, then this field shall indicate that the astp_rimeiitamp field contains no valid data and therefore shall be ignored by an AVTP Listener.
If the av_tinwstamp_valid bit is set to one (I) by the AVTP Talker, then this field shall indicate that the astp_timeatamp field is valid.
For how the astp_timestamp field is interpreted and processed. see 5.4.8.
5.4.5 sequence_num: (sequence number) field
The sequence number bit field srqucnce_numl is an 8 bit field used to indicate the sequence of AVTPDUS in a stream by the Talker. This field may statS at any value for the firs; AVTPDU of a stream and shall he incremented by one(l), with wrapping, on each subsequent AVTPDD of a stream.
The value of this field is determined by the Talker, Listeners can use the sequence number to detect AVTPLDJs lost in transmission.
5.4.6 reserved: (reserved) field
The reserved field is a 7 bit field reserved for future use in stream data AVTPDU headers. This field is set to zero (0) on transmit and ignored on receive.
