Abstract
A method and apparatus for the transmission of multiple control characters of the same type to a receiver to improve the retention of transmitter to receiver synchronization in a noisy environment having receiver code that is less complex and does not require an increase in the bandwidth of the system since the control codes are already utilized to initiate other functions. Detection of any of the control characters of the same type by the receiver allows the receiver to maintain proper synchronization. The receiver will detect these control signals and anticipate the occurrence of an event within a predetermined time period.
Claims20
A data transfer system that maintains synchronization within a communication system comprising:
- a transmitter device within said communication system, said transmitter circuit being configured to transmit data and control characters across an interface;
- a receiver device within said communication system, said receiver circuit being operatively connected to said interface to receive data and control characters from said transmitter device;
- an identification device within said receiver device that can recognize characters transmitted across said interface such that said receiver can detect a plurality of control words as control characters being indicative of a single event;
- and
- a timing device within said receiver device for creating time intervals after detection of one of said control words with respect to said single event.
A communication method for maintaining data synchronization comprising the steps of:
- providing an interface from a transmitter to a receiver with said transmitter being configured to transmit data and control characters across said interface and said receiver being operatively connected to said interface to receive data and control characters from said transmitter;
- forming an identification device within said receiver that can recognize characters transmitted across said interface including a plurality of control words transmitted across said interface as control characters being indicative of a single event;
- sending characters across said interface including said plurality of control words such that a predetermined interval exists between each of said plurality of control words and data;
- and
- generating a timing pulse after a predetermined time period after detection of one of said control words.
