A concise summary of US Patent US7391791B2 is as follows:

Title: Method and system for synchronization of content rendering

Assignee: Implicit Networks, Inc.

Inventors: Information not authoritatively available.

Filing Date: December 17, 2001

Issue Date: June 24, 2008

Abstract:
A method and system for synchronizing the rendering of content at multiple rendering devices. The system comprises a master device and multiple slave devices. The master device receives a content stream and sends synchronization messages to the slave devices. The synchronization messages contain timing information that allows the slave devices to adjust their rendering of the content to match the master device. This ensures that the content is rendered in a synchronized manner across all devices.

Plain-Language Overview of Each Independent Claim:

Uncertainty Note: Without the full and definitive text of the patent claims, which could not be authoritatively located through public search at this time, a precise analysis of the independent claims is not possible. Independent claims are the broadest claims of a patent and define the core of the invention. A general understanding, based on the patent's title and abstract, suggests that the independent claims likely cover the following aspects:

• A primary method or system for achieving synchronized content playback across multiple devices. This would likely involve a master device that controls the timing and sends synchronization information to one or more slave devices over a network. The claim would broadly outline the steps of receiving content, generating timing information, transmitting that information, and the slave devices adjusting their playback accordingly.

• A master device configured for synchronized content distribution. This claim would focus on the apparatus or system that acts as the central controller. It would describe the components of the master device, such as a content receiver, a clock, a synchronization message generator, and a network interface for sending those messages.

• A slave device designed to operate within a synchronized content playback system. This claim would describe the apparatus or system that receives the synchronized content. It would detail the components of the slave device, including a network interface for receiving content and synchronization messages, a content renderer (like a speaker or screen), and a mechanism for adjusting the rendering speed based on the timing information from the master device.
