Synchronized transmission of audio and video data from a computer to a client via an interface

In an interface between a computer and a video client, a method of performing data transmission flow control, the method comprising:

• receiving a stream of input data from the video client according to a first format;
• converting the received input data to an output data according to a second format, the converting comprising generating one or more video data and one or more blanking intervals, the video data configured for display on the computer;
• and
• for each generated blanking interval, transmitting the output data from the interface, the transmitted output data enabling the computer to synchronize to the output data based on a rate of blanking interval reception.

A computer readable apparatus having a storage medium containing instructions which, when executed by a computerized device:

• responsive to receiving a stream of input data according to a first format, convert the received input data to an output data according to a second format comprising one or more video data and one or more blanking intervals, the video data configured for display on a first device;
• for each blanking interval, transmit the video data;
• and
• wherein the video enables the first device to derive a display rate for the video data based at least in part on a determined frequency of blanking intervals.

A computer readable apparatus having a storage medium containing instructions which, when executed by a computerized device:

• responsive to receiving data from a peer device, according to a first format comprising one or more video data and one or more blanking intervals, determine a frequency of receipt for the one of more blanking intervals;
• for each blanking interval, display a corresponding video data;
• and
• synchronize to the peer device, based at least in part on the determined frequency of blanking intervals.
