Solution Overview

Problem

The periodic transmission of large manifests associated with time-shifted multimedia content consumes excessive network bandwidth and CPU resources, particularly in low-speed internet connections, leading to degraded playback performance.

Innovation Solution

Implement a method where initial playback uses smaller manifests of the first type, and upon selection of a command, a request is sent to access the larger manifests of the second type, which are then used for playback, thereby delaying the transmission of the larger manifests until necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If periodic transmission of large manifests is implemented for time-shifted content, then content replay capability is improved, but network bandwidth consumption increases

Engineering Contradiction:
Improvecontent replay capabilityVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments manifest transmission into two types: small manifests for real-time playback and large manifests for time-shifted content. The system selectively transmits only the necessary manifest type based on playback mode, avoiding unnecessary transmission of large manifests during normal real-time viewing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between different manifest types based on user commands. When a user requests time-shifted content, the system transitions from using small manifests to large manifests, adapting the transmission behavior to the current playback requirements.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If periodic transmission of large manifests is implemented, then time-shifted playback capability is improved, but CPU load increases

Engineering Contradiction:
Improvetime-shifted playback capabilityVSAvoidCPU load
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the manifest handling into two distinct approaches: using small manifests for real-time playback and large manifests only when time-shifted content is requested. This segmentation reduces unnecessary processing of large manifests during normal operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses periodic transmission of small manifests for real-time playback, but switches to on-demand transmission of large manifests only when time-shifted content is required, reducing continuous CPU processing load.

Inventive Principle:
Principle #19Periodic action

3Quantity of substance

If small manifests are used for initial playback, then network bandwidth usage is reduced, but content replay capability is limited

Engineering Contradiction:
Improvenetwork bandwidth usageVSAvoidcontent replay capability
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts manifest selection based on user needs. During normal real-time playback, small manifests are used to conserve bandwidth. When a user commands time-shifted playback, the system transitions to using large manifests that provide comprehensive content history.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent extracts the time-shifted content capability from the standard real-time playback flow. Large manifests containing historical content are only retrieved and processed when specifically needed through user commands, separating this functionality from the normal playback path.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method for managing access to manifests associated with content distributed in real time, playback of the content requiring receipt, from a communication network, of manifests of a first type or of a second type, a control interface being accessible during playback. The method includes an initial playback carried out by using manifests of the first type, and, during playback, a request for access to the manifest of the second type is transmitted if a command is selected, playback continuing by using manifests of the second type received from the network.
