RDMA BASED REAL-TIME VIDEO CLIENT PLAYBACK ARCHITECTURE

摘要

A client playback architecture for a media content distribution system is provided. In the preferred embodiment, the client playback architecture is a Remote Direct Memory Access (RDMA) based architecture. The RDMA based architecture enables the client playback device to obtain media content from a central server in real-time or in substantially real-time as the media content is needed for playback at the client playback device. More specifically, the playback device includes RDMA enabled playback circuitry operating to perform RDMA transfers for select media content, buffer the media content received as a result of the RDMA transfers, and provide the media content for presentation to one or more associated viewers via one or more audio/video interfaces.

1. A system comprising:
a network interface; playback circuitry associated with the network interface comprising:
a first buffer circuit associated with the network interface and configured to:
receive an address range of select media content defining a range of addresses in a storage unit of a media content server in which the select media content is stored; andperform at least one direct memory access transfer via the network interface to transfer data stored in the address range from the storage unit of the media content server to the first buffer circuit; anda second buffer circuit associated with the first buffer circuit comprising:
a media content processing function configured to:
receive the data from the first buffer circuit based on a playback rate;process the data to provide the select media content in a format ready for playback; andstore the select media content for playback.
