Abstract

A method and an apparatus for converting multimedia data of a digital format to multimedia data of an analog format, such as NTSC or PAL is disclosed, multimedia synchronous digital multimedia interfaces may be supported in a similar manner. The digital format includes image data and timing data where the timing data includes presentation times stamp information for the image data and is compatible with a communication system in which the transmitter and receiver operate based on a global clock, such as a GPS clock.

Description

[0001] Related Application Cross Reference [0002] This application claims priority over the U.S. provisional application filed on March 10, 2005 and entitled "A METHOD OF TIME BASE RECONSTRUCTION FOR DISCRETE TIME LABELED VIDEO" Application Serial No. 60 / 660,584, which is hereby incorporated by reference in its entirety. technical field [0003] The field of the invention relates to multimedia data, and more particularly to processing multimedia data. Background technique [0004] Streaming media over the Internet and mobile / wireless channels has attracted significant attention due to the explosive growth and apparent success of the Internet and wireless communications, as well as the ever-increasing demand for multimedia services. In heterogeneous Internet Protocol (IP) networks, video is provided by a server and can be streamed by one or more clients. Wired connections include: dial-up, Integrated Services Digital Network (ISDN), cable, Digital Subscriber Line Protocol...
