AI Technical Summary

Problems solved by technology

Design considerations for codecs include issues such as bandwidth scalability over the network, computational complexity of encoding / decoding data, resilience to network loss (data loss), and the encoder used to deliver the data representing the media stream / decoder wait time
However, FEC requires the transmitter of the data stream to account for the loss of data packets resulting in deteriorating network conditions or affecting the encoder that encodes the data wirelessly

Embodiment Construction

[0012] As used herein, encoded and transmitted multimedia-related data represents a media object. Throughout the present invention, the terms information and data are also used synonymously to describe audio / video data before or after encoding. The term media object includes audio, video, text, multimedia data files and streaming media files. Multimedia files include any combination of text, image, video, and audio data. Streaming media, including audio, video, multimedia, text and interactive data files, is provided to the user's device through the Internet or other communication network environment, and starts playing on the user's computer / device before the transmission of the entire file is completed. One advantage of streaming is that the streaming file starts playing before the entire file is downloaded, saving the user the long wait typically associated with downloading the entire file. Digitally recorded music, movies, trailers, news reports, radio broadcasts and liv...

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.

Description

technical field [0001] The present invention relates to the field of transmitting prioritized packets based on network conditions. Background technique [0002] With the development of communication networks (network structures) such as the Internet and the widespread acceptance of broadband connections, clients have a need for video and audio packets (e.g., TV programs, movies, video conferencing, radio, etc.) that can be selected and transmitted through the communication network as needed. programs) etc. Video services, known as media objects or streaming audio / video, often suffer from quality issues due to the bandwidth limitations and bursty nature of communication networks typically used to stream video transmissions. Therefore, the design of a streaming media delivery system must consider the codec (encoder / decoder program) used to deliver the media objects, the quality of service (QoS) issues in displaying the delivered media objects, and the The transmission of inf...
