Methods and systems for optimal delivery of internet video over wireless networks

A method for controlling multimedia data transmission to a communication device via a network, the method being performed by one or more processors of a server and comprising:

• obtaining first multimedia data for transmission;
• evaluating, based on timestamps included in second multimedia data that have been transmitted prior to the first multimedia data and an elapsed time for transmitting the second multimedia data, an estimated buffer time associated with the communication device, wherein the estimated buffer time represents an estimation of an amount of multimedia data stored in a buffer of the communication device
• responsive to-the estimated buffer time satisfying a first threshold condition, updating a current transmitting state to be a pacing state, and
• responsive to the estimated buffer time satisfying a second threshold condition, updating the current transmitting state to be a bursting state;
• and
• transmitting the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.

A non-transitory computer readable storage medium storing a set of instructions that are executable by at least one processor of a server to cause the server to perform a method for controlling multimedia data transmission to a communication device via a network, the method comprising:

• obtaining first multimedia data for transmission;
• evaluating, based on timestamps included in second multimedia data that have been transmitted prior to the first multimedia data and an elapsed time for transmitting the second multimedia data, an estimated buffer time associated with the communication device, wherein the estimated buffer time representing an estimation of an amount of multimedia data stored in a buffer of the communication device;
• if the estimated buffer time satisfies a first threshold condition, updating a current transmitting state to be a pacing state, and
• if the estimated buffer time satisfies a second threshold condition, updating the current transmitting state to be a bursting state;
• and
• transmitting the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.

A method for controlling multimedia data transmission to a communication device via a network, the method being performed by one or more processors of a server and comprising:

• obtaining a first multimedia data for transmission;
• transmitting a first portion of the first multimedia data at a transmitting rate corresponding to a pacing state;
• evaluating, based on timestamps included in the first portion of the first multimedia data and an elapsed time for transmitting the first portion of the first multimedia data, an estimated buffer time associated with the communication device, wherein the estimated buffer time represents an estimation of an amount of multimedia data stored in a buffer of the communication device;
• updating, based on the evaluation of the estimated buffer time, the current transmitting state from a pacing state to a bursting state;
• and
• transmitting a second portion of the first multimedia data at a transmitting rate corresponding to the bursting state.
