Member Description
mailbox # (c_av_st_video_item) m_video_items= new(0);
—
t_pixel_format pixel_transport = parallel;
The Avalon-ST video standard allows you to send
symbols in serial or parallel format. You can set
this control to either format.

int video_packets_sent = 0;
—
int control_packets_sent = 0;
—
int user_packets_sent = 0;
—
int readiness_probability = 80;
Determines the probability of when a sink or
source is ready to receive or send data in any given
clock cycle, as manifested on the bus by the
READY
and
VALID
signals, respectively.
