Currently, the vivid emulation of cec message transmission does not force adapters to wait until the cec bus has been signal-free for a certain number of bit periods before transmitting or re-transmitting a message. Without enforcing the signal-free time requirements, adapters do not share the bus very well and some messages are sent too quickly while other messages are lost. By emulating a signal-free time and forcing adapters to wait their turn to transmit, the vivid emulation of cec transmission is much more reliable.
