AI Technical Summary

Problems solved by technology

For example, desktop video can consume disk space at a rate of over 1GB per hour, and the complexity of the video encoding process is such that video transcoding typically takes between 1 / 2 and 2 times the "real time" to complete
Therefore, it may no longer be acceptable to do all file transcoding at the actual time the media file is being transferred to the playback device

Embodiment Construction

[0024] introduce

[0025] The following discussion is directed to systems and methods for transcoding media content in the background on a source computer device, such as before the target media playback device is connected to the source computer for synchronization of the media content. The systems and methods predict which media content to background transcode based on user input rules and media state data maintained in a transcoding database. Pre-transcoding media content as described herein provides several advantages, including a significant reduction in the time required to synchronize media content between a source computer and a target media playback device. Another advantage is efficient use of CPU power for pre-transcoding media content at times when the CPU may be idling.

Abstract

A system and methods are described for transcoding media content in the background on a source computer device prior to such time as a target media playback device is connected to the source computer for synchronization of the media content. The system and methods anticipate which media content to background-transcode based on user input rules and media status data that are maintained in a transcode database. Pre-transcoding media content provides advantages that include a significant reduction in the time needed to synchronize media content between a source computer and a target media playback device, and an efficient use of CPU power for transcoding media content at times when the CPU might otherwise stand idle.

Description

technical field [0001] The present disclosure relates generally to synchronizing media content between a source device and a target playback device, and more particularly to pre-transcoding media content prior to synchronization by connecting devices. Background technique [0002] As digital media technology continues to advance and storage costs continue to decrease, users are increasingly hosting and consuming digital media on their own host computers (eg, desktop PCs). Examples of such digital media include music, video, still pictures, and the like. [0003] Furthermore, the corresponding increase in the availability of portable media playback devices such as personal digital assistants (PDAs), handheld computers, laptop computers, and smart phones has provided users with more ubiquitous access to information than ever before. As users increasingly rely on such portable computing devices, there is a growing need for applications that efficiently transfer digital media f...
