An apparatus comprising: a data source element (105, 302, 402, 502) configured to provide audiovisual data to a receiver (120, 308, 408, 508) being authenticated using an authenticating protocol; and a first bridge element (110, 304, 404, 504) coupled between the data source element and the receiver, the first bridge element configured to: convert the audiovisual data from a first protocol to a second protocol; receive an operation command from the data source element, the operation command for receipt by the receiver and requiring a response from the receiver to the data source element within a predetermined time frame defined by the authenticating protocol, characterized by the first bridge element being further configured to handle the operation command for a read operation by responding to the data source element within the predetermined time frame without sending the received operation command to the receiver by at least translating a sequential read command to a short read command by filtering out a slave address and an offset included in the sequential read command to handle at least a part of a handshake operation without the receiver thereby to reduce or eliminate clock stretching of the data source element caused by the sequential read command, the short read command requiring less time to complete than the sequential read command. a data source element (105, 302, 402, 502) configured to provide audiovisual data to a receiver (120, 308, 408, 508) being authenticated using an authenticating protocol; and a first bridge element (110, 304, 404, 504) coupled between the data source element and the receiver, the first bridge element configured to: convert the audiovisual data from a first protocol to a second protocol; receive an operation command from the data source element, the operation command for receipt by the receiver and requiring a response from the receiver to the data source element within a predetermined time frame defined by the authenticating protocol, characterized by the first bridge element being further configured to handle the operation command for a read operation by responding to the data source element within the predetermined time frame without sending the received convert the audiovisual data from a first protocol to a second protocol; receive an operation command from the data source element, the operation command for receipt by the receiver and requiring a response from the receiver to the data source element within a predetermined time frame defined by the authenticating protocol, characterized by the first bridge element being further configured to handle the operation command for a read operation by responding to the data source element within the predetermined time frame without sending the received operation command to the receiver by at least translating a sequential read command to a short read command by filtering out a slave address and an offset included in the sequential read command to handle at least a part of a handshake operation without the receiver thereby to reduce or eliminate clock stretching of the data source element caused by the sequential read command, the short read command requiring less time to complete than the sequential read command.
