US 9762639

Here's a concise summary of US Patent 9762639:

Title: Dynamic manifest generation based on client identity
Assignee: Adeia Media Holdings Inc. (current), Brightcove Inc. (original)
Inventors: Albert John McGowan, Michael M. Gordon
Filing Date: October 28, 2016
Issue Date: September 12, 2017
Abstract: The patent describes techniques for dynamically rewriting timestamps in media streams that transition between different sources, such as live content and on-demand content, to ensure error-free streaming for the client. This is achieved by coordinating the creation of a client manifest with the dynamic generation of media segments ("chunks") to apply continuous timestamps across the transition.

Plain-Language Overview of Independent Claims:

Please note: The provided patent text does not include the numbered "Claims" section. Instead, it describes "An example method," "An example server," and "An example non-transitory computer-readable medium" within its "Definitions" and "Brief Summary of the Invention" sections. These descriptions typically correspond to the independent claims in a patent. The following overviews are based on these exemplary descriptions.

• Example Method Claim (Method of Providing Media Streaming):
  This method involves a system receiving a live media stream and its timing information. When a request to stream this live content is received, the system creates a manifest file. This manifest file is unique because it contains information for streaming parts of the live media and parts of a separate media file (like an advertisement). Crucially, the manifest includes "offset information" derived from the live stream's timing to ensure that the distinct media file segments are presented with continuous timestamps, thereby preventing playback errors during transitions between live and non-live content. The manifest file is then sent to the requesting client.

• Example Server Claim (Server for Providing Media Streaming):
  This claim describes a server equipped with a communications interface, memory, and a processing unit. The processing unit is configured to perform the actions outlined in the example method. Specifically, it receives live media content, obtains its timing information, and responds to a request to stream this content by creating a manifest file. This manifest file, as described above, includes information for both live and distinct media segments, along with offset information for continuous timestamps. The server then sends this manifest file.

• Example Computer-Readable Medium Claim (Non-Transitory Computer-Readable Medium):
  This claim covers a non-transitory computer-readable medium (e.g., storage device) containing instructions. When a computer executes these instructions, it performs the steps of the example method. These steps include receiving live media, obtaining its timing data, receiving a streaming request, and then creating and sending a manifest file that facilitates continuous timestamp playback for mixed live and distinct media content using offset information.

Litigation Information:

Based on the provided patent information, US9762639B2 is currently active.

• A PTAB case, IPR2026-00054, was filed and has a status of "Procedural Termination".
• A US case was filed in the Delaware District Court, case number 1:24-cv-01231.

No CAFC 2026 dockets specifically citing US9762639B2 were found in a live search at this time.## US Patent 9762639: Dynamic Manifest Generation Based on Client Identity

Here's a concise summary of US Patent 9762639, "Dynamic manifest generation based on client identity":

Title: Dynamic manifest generation based on client identity
Assignee: Adeia Media Holdings Inc. (current assignee as of June 4, 2024), Brightcove Inc. (original assignee)
Inventors: Albert John McGowan, Michael M. Gordon
Filing Date: October 28, 2016
Issue Date: September 12, 2017
Abstract: The patent describes techniques for dynamically rewriting timestamps in streams of media that transition from one media source to another (e.g., live content to on-demand content, or vice versa) to ensure error-free streaming by the client. This is achieved by coordinating the creation of a client manifest with the dynamic creation of requested media segments ("chunks") to determine how to rewrite timestamps, ensuring they remain continuous throughout the transition.

Plain-Language Overview of Independent Claims:

The provided patent text does not explicitly list numbered claims, but instead details "An example method," "An example server," and "An example non-transitory computer-readable medium" in its summary sections, which typically correspond to the independent claims. These overviews are derived from those exemplary descriptions within the patent text.

• Example Method Claim (Method of Providing Media Streaming):
  A method for streaming media involves receiving a live media data stream and obtaining its timing information. Upon receiving a request to stream this live content, a processing unit creates a manifest file. This manifest file is unique because it includes information for streaming both segments of the live media content and segments of a distinct media file (e.g., an advertisement). Crucially, the manifest file also contains "offset information" based on the live media's timing, which is used to ensure that the timestamps of the distinct media file segments are rewritten to be continuous with the live content, preventing playback errors during transitions. The manifest file is then sent to the client.

• Example Server Claim (Server for Providing Media Streaming):
  This describes a server designed for media streaming, comprising a communications interface, memory, and a processing unit. The processing unit is configured to perform the functions of the example method: receiving a live media data stream, obtaining its timing information, and receiving a request to stream the live content. It then creates a manifest file that includes information for streaming segments of both live media and a distinct media file, incorporating offset information to maintain continuous timestamps during transitions. Finally, the server sends this manifest file via its communications interface.

• Example Computer-Readable Medium Claim (Non-Transitory Computer-Readable Medium):
  This claim pertains to a non-transitory computer-readable medium (e.g., a storage device) with embedded instructions. When a computer executes these instructions, it performs the steps of the example method. These steps include receiving live media content, obtaining its timing information, receiving a request to stream the live content, and then creating and sending a manifest file that facilitates continuous timestamp playback for mixed live and distinct media content using offset information.

Litigation Information:

The patent US9762639B2 is currently active.

• A PTAB case, IPR2026-00054, was filed and subsequently marked with a "Procedural Termination" status.
• A US case (1:24-cv-01231) was filed in the Delaware District Court.
