US Patent 10,715,806: Video Transcoding with Metadata

Title: Systems, methods, and media for transcoding video data

Abstract:
The patent describes methods, systems, and computer-readable media for transcoding video data using metadata. These methods involve receiving a first set of encoded images from storage, decoding them based on a first coding scheme to produce decoded images, receiving encoding parameters (metadata) from storage, and then encoding the decoded images into a second set of encoded images using a second coding scheme and the received encoding parameters.

Independent Claim Overviews:

Claim 1: Method for Transcoding with Metadata and Parallel Processing
This claim outlines a method for converting a source video file into multiple alternative video streams. It involves a "media metadata generation device" (a computer system) that creates metadata for the source video, including scene complexity information, before or during transcoding a portion of the source video. This metadata information is then sent to several "transcoding devices." Each of these transcoding devices then performs the following steps in parallel:

1. Receives a portion of the source video (first encoded images) from a media content source.
2. Decodes this portion of the video using its original "source format" to get decoded images.
3. Receives the metadata information from the computer system.
4. Encodes these decoded images into an "alternate video stream" (second encoded images) using a "target format" and the received metadata. This alternate video stream is one of the multiple streams being created.

Claim 11: System for Transcoding with Metadata and Parallel Processing
This claim describes a system that performs the method of Claim 1. The system comprises two main components:

1. A "computer system configured as a media metadata generation device" which is set up to generate media metadata (including scene complexity information) for a source video file prior to or during decoding/transcoding, and to provide this metadata to multiple transcoding devices.
2. A "plurality of transcoding devices" that are configured to operate in parallel. Each device is capable of:
   • Receiving a portion of the source video (first encoded images) in a "source format."
   • Decoding this portion to produce decoded images.
   • Receiving the metadata from the computer system.
   • Encoding the decoded images into an "alternate video stream" (second encoded images) using a "target format" and the metadata, where this stream is one of several.

Claim 21: Method for Transcoding with Specific Metadata Details and Resolution/GOP Determination
This claim presents another method for transcoding a source video file into multiple alternate video streams, similar to Claim 1, but with additional specific details regarding the metadata and encoding steps. It specifies that the media metadata generated by the "media metadata generation device" includes both scene change information (indicating scene start and end) and scene complexity information. Furthermore, it explicitly states additional parallel steps performed by each transcoding device:

1. Receiving the source video portion and decoding it to generate decoded images.
2. Receiving the metadata.
3. Dividing an image within the decoded images into coding units based on a "target format."
4. Specifies that the "source format" and "target format" have different resolutions.
5. Determining the number of bits to encode a "group of pictures" (GOP) based, at least in part, on the number of frames between the start and end of a scene, as indicated by the metadata.
6. Encoding the decoded images into an alternate video stream using the "target format" and the metadata.
