Multimedia server with simple adaptation to dynamic network loss conditions
First Claim
1. A method for communicating data representing a media object encoded into classified data representing base layer information and enhancement layer information through a network fabric comprising the steps of:
- transmitting a composition of the classified data as prioritized data in response to network conditions wherein the classified data comprises at least one of base layer information with associated parity information;
adjusting a composition of prioritized data for transmission in response to a change in network conditions wherein the composition of classified data is modified with enhancement layer information.

Abstract
A method for transmitting prioritized data encoded by a Forward Error Coding operation wherein a media object is separated into different classes of data forming a base layer and at least one enhancement layer of information, with each layer having associated parity data. Data of the separated media object, formed of classified data, is later encoded and stored, whereby information of the base layer is assigned a higher priority for transmission than enhancement layer data. Such priority classifications are used when a server transmits the classified data over a network fabric as prioritized data. Optionally, the composition of transmitted classified data is adjusted in view of a change in network conditions.

13. A method for communicating data representing a media object comprising the steps of:
-
determining network conditions;
transmitting prioritized data in accordance with network conditions, wherein the prioritized data is generated as a composition of classified data representing at least one base layer of information and at least one enhancement layer of information with parity data being associated with each layer of information; and
the composition of transmitted base layer information with associated parity data and the enhancement layer information with associated parity data is determined in response to network conditions. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for decoding communicated data representing a media object comprising the steps of:
-
processing prioritized data, wherein the prioritized data represents a composition of classified data that is pre-encoded into at least one base layer of information and at least one enhancement layer of information with parity data being associated with each layer of information; and
requesting that the composition of classified data transmitted as prioritized data change to reflect different network conditions. - View Dependent Claims (21)
