ELECTRONIC DEVICE SUPPORTING MULTI-EDID READ OPERATION AND OPERATING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240013747 titled 'ELECTRONIC DEVICE SUPPORTING MULTI-EDID READ OPERATION AND OPERATING METHOD

Simplified Explanation

The abstract describes an operating method for an electronic device that communicates with a source device through an HDMI interface. The method involves determining if the source device supports a multi-extended display identification data (EDID) read operation through a display data channel (DDC). If supported, the method sequentially transmits an EDID set stored in a non-volatile memory to the source device using an EDID group corresponding to the size of a cache memory as a transmission unit.

  • The method determines if the source device supports multi-extended EDID read operation through DDC.
  • If supported, the method transmits an EDID set stored in non-volatile memory to the source device.
  • The EDID set is transmitted sequentially using an EDID group corresponding to the size of the cache memory.
  • The size of the EDID set and cache memory determines the transmission unit.

Potential applications of this technology:

  • This technology can be used in electronic devices that communicate with source devices through HDMI interfaces.
  • It can be applied in devices that require EDID data exchange, such as monitors, TVs, and projectors.
  • The method can be used to ensure proper communication and compatibility between the electronic device and the source device.

Problems solved by this technology:

  • The method solves the problem of determining if a source device supports multi-extended EDID read operation through DDC.
  • It addresses the issue of transmitting EDID data from an electronic device to a source device in a sequential and efficient manner.
  • The method solves compatibility issues by using an EDID group corresponding to the size of the cache memory.

Benefits of this technology:

  • The method allows for efficient and sequential transmission of EDID data, improving the communication between electronic devices and source devices.
  • It ensures compatibility between devices by determining if the source device supports multi-extended EDID read operation.
  • The technology simplifies the process of transmitting EDID data by using an EDID group based on the size of the cache memory.


Original Abstract Submitted

an operating method for an electronic device that communicates with a source device through a high definition multimedia interface (hdmi), includes determining whether the source device supports a multi-extended display identification data (edid) read operation through a display data channel (ddc) and sequentially transmitting an edid set stored in a non-volatile memory to the source device using an edid group corresponding to a size of a cache memory, as a transmission unit, based on a size of the edid set and the size of the cache memory, when it is determined that the multi-edid read operation is supported.
