Here's an analysis of the most relevant prior art for US patent 9036010, based on its cited references and the claims of US9036010.

The claims of US9036010 generally pertain to a digital display interface part and related methods for transporting stereoscopic image data over a digital display interface (such as HDMI), utilizing existing data carrying capacity (e.g., deep color modes) by multiplexing stereoscopic components, and using signaling information (e.g., Data Island Packets) to identify the format and characteristics of the stereoscopic data. Some claims also cover distributing stereoscopic data between primary and auxiliary channels.

Here are the cited prior art references, their descriptions, and potential anticipation:

    • Full Citation: US20020009137A1 (Nelson John E.)
    • Publication/Filing Date: Published: 2002-01-24; Priority: 2000-02-01
    • Brief Description: This patent application describes a three-dimensional video broadcasting system that encodes 3D video images by spatially multiplexing left and right eye images into a 2D compatible format. It suggests embedding synchronization pulses within standard video blanking intervals to trigger 3D displays. The system aims to transmit 3D video over existing 2D video infrastructure.
    • Potential Anticipation (35 U.S.C. § 102):
      • Claims 1, 12, 16, 18 (first mode for 2D images): This reference teaches systems designed for 2D compatible formats, implying a first mode for 2D images.
      • Claims 1, 12, 16, 18 (second mode for multiplexed stereoscopic image): The core idea of spatially multiplexing left and right eye images into a 2D compatible format directly relates to multiplexing components of a stereoscopic image for transport over an interface.
      • Claims 6, 15: Specifically teaches "left and right eye images."
      • Claims 3, 4, 13, 14 (signaling in blanking periods/Data Island Packets): The reference mentions "embedding synchronization pulses within standard video blanking intervals to trigger 3D displays." This strongly suggests the use of auxiliary data in blanking periods for 3D signaling, which could potentially anticipate the use of Data Island Packets for signaling.
      • Claim 7, 8: While not explicitly stating sequential transmission, the idea of encoding left and right eye images for a 2D compatible stream could encompass sequential or interleaved approaches.

Most Relevant Prior Art Summary:

Based on the descriptions, the most directly anticipatory references, particularly regarding the core claims of multiplexing stereoscopic data components and using signaling, appear to be:

  • JP2007325101A (Sony Corp): This patent directly teaches multiplexing left/right images or 2D/depth into a single stream and signaling the 3D format, anticipating many elements of Claims 1, 2, 6, 10, 11, 12, 13, 15, 16, 17, 18.
  • US20070296859A1 (Sony Corporation): Similar to the above, it teaches multiplexing multiple video signals (left/right) into a single stream and using auxiliary information for identification, anticipating Claims 1, 2, 6, 12, 13, 15, 16, 17, 18.
  • WO2006137006A2 (Koninklijke Philips Electronics N.V.): This patent, from the same original assignee, specifically addresses transmission of 2D+depth, embedding depth in blanking intervals, and signaling, strongly anticipating Claims 1, 2, 3, 4, 10, 11, 12, 13, 14, 16, 17, 18.
  • US20020009137A1 (Nelson John E.): Its teaching of spatially multiplexing left/right images into a 2D compatible format and embedding synchronization in blanking intervals is a strong early anticipation of the core multiplexing and signaling concepts for 3D over 2D infrastructure.
  • US6914637B1 (Silicon Image, Inc.): While not specific to 3D, it lays the groundwork for using auxiliary data in blanking intervals (like Data Islands) over interfaces like HDMI, which is a key enabling technology for the signaling aspects of US9036010, thereby potentially anticipating Claims 3, 4, 13, 14.

These references collectively disclose methods of multiplexing stereoscopic image components (L/R or 2D+depth), transmitting them over existing display interfaces, and using signaling (often in blanking periods or via auxiliary data) to inform the receiver about the stereoscopic format. While US9036010 emphasizes utilizing "deep color modes" specifically, many of these references already establish the fundamental techniques of multiplexing and signaling for 3D data transmission that could be adapted to higher bandwidth modes.
