US 2017/0318068 A1 · LOW LATENCY MULTIMEDIA STREAMING SYSTEM AND METHOD

Abstract

In one example, a method for low-latency multimedia stream reception and output in a receiving device is described. Data packets may be extracted from a multimedia stream received over a network. The sequence of independently decodable units associated with the multimedia stream may be decoded. Each independently decodable unit may include one or more data packets. The sequence of decoded units may be stored in an output buffer. Further, flow of the decoded units from the output buffer to an output device may be controlled based on one of (a) a latency associated with the decoded units and (b) a rate of reception of the decoded units by the output buffer and a rate at which the output device is operating. The decoded units may be rendered on the output device.

Dependent claims

A receiving device comprises:

a network unit to extract data packets from a multimedia stream received over a network;
a processing unit comprising:
a decoder to decode a sequence of independently decodable units associated with the multimedia stream to output a sequence of decoded units, wherein each independently decodable unit comprises at least one data packet;
and
an output buffer to store the sequence of decoded units;
and
an output rate control unit to control flow of the decoded units from the processing unit to an output device based on one of (a) a latency associated with the decoded units and (b) a rate of reception of the decoded units by the output buffer and a rate at which the output device is operating, wherein the output device is to render the decoded units.
