US Patent:

20120307654, Dec 6, 2012
Filed:

Jun 3, 2011
Appl. No.:

13/153372
Inventors:

Roger Pantos - Cupertino CA, US
Thai W. Then - Santa Clara CA, US
International Classification:

H04L 12/26
US Classification:

370252
Abstract:

Some embodiments provide a method for estimating bandwidth estimate based on a set of statistical measurements that quantifies bandwidth variation. The method receives a piece of media content at a receiving device and computes several instantaneous bandwidth measurements based on sample data blocks or media content received at the receiving device. The method computes the set of statistical measures that quantifies variation between the computed instantaneous bandwidth measurements. Based on the set of statistical measures, the method computes a revised bandwidth estimate for receiving media content at the receiving device. In some embodiments, the method uses the revised bandwidth estimate to determine an amount of media content data to buffer in order to provide an uninterrupted playback.

Filed:

Jun 23, 2005
Appl. No.:

11/166684
Inventors:

Christopher Lance Flick - San Jose CA, US
Thai Wey Then - Santa Clara CA, US
Assignee:

Apple Inc. - Cupertino CA
International Classification:

G06F 17/20
G06F 15/16
US Classification:

707792, 719328
Abstract:

A method and system for accessing media metadata from metadata stored in different native formats is disclosed. A repository contains a plurality of containers for storing media metadata, wherein a first container in the repository stores metadata in the first native format, and a second container in the repository stores metadata in the second native format. A set of routines is used to access all media metadata stored in the repository without regard to the native format in which the media metadata is stored. Each routine in the set of routines identifies a metadata item stored in a container through information passed in a set of parameters. The set of parameters comprises a reference to the repository, an identifier of a container in the repository, an identifier of a structure for a key for the identified native format, and a key.
