US 10,257,438 B2 · Automatic identification and mapping of consumer electronic devices to ports on an HDMI switch

Abstract

Methods, systems, and apparatuses are described for automatic identification and mapping of consumer electronic devices to ports on an HDMI switch. A device that is connected to an HDMI switch is identified based on data received over an HDMI connection, and ports on the HDMI switch are automatically mapped and configured. Methods, systems, and apparatuses are described for back-end database creation for automatic identification and mapping of consumer electronic devices to ports on an HDMI switch. The back-end database may be created by the based on video and audio signatures received from a consumer electronic device and based on remote control information and signatures.

Dependent claims

A method for generating a database of signatures for automatic identification and mapping of an electronic device to a port on a high-definition media interface (HDMI) switch, the method comprising:

generating a digital video fingerprint by:
capturing a logo that is displayed on a display, the logo comprising video data and identifying the electronic device, during a boot up of the electronic device or during a normal operation of the electronic device, the digital video fingerprint comprising a perceptual-hash (p-Hash) that is generated by:
converting the video data to a gray scale format to generate gray scale video data;
scaling down a resolution of the gray scale video data;
applying a discrete cosine transform (DCT) to the gray scale video data;
extracting one or more data coefficients from the DCT;
and
generating a p-Hash value from a matrix of low-frequency energy coefficients from the one or more data coefficients;
generating at least one signature of the electronic device, the at least one signature comprising a video signature that includes the digital video fingerprint;
and
associating at least the signature with an electronic device name or identifier that corresponds to the electronic device in the database.

8 more elements

A system comprising:

at least one memory configured to store program instructions for generating a database of signatures for automatic identification and mapping of an electronic device to a port on a high-definition media interface (HDMI) switch;
and
at least one processing device configured to execute the program instructions, the program instructions including:
first instructions to:
generate at least one signature of the electronic device, the at least one signature of the electronic device comprising a video signature;
and
generate the video signature to include a digital video fingerprint;
second instructions to generate the digital video fingerprint by:
capturing a logo that is displayed on a display, the logo comprising video data and identifying the electronic device, during a boot up or during a normal operation of the electronic device, the digital video fingerprint comprising a perceptual-hash (p-Hash) that is generated by third instructions to:
convert the video data to a gray scale format to generate gray scale video data;
scale down a resolution of the gray scale video data;
apply a discrete cosine transform (DCT) to the gray scale video data;
extract one or more data coefficients from the DCT;
and
generate a p-Hash value from a matrix of low-frequency energy coefficients from the one or more data coefficients;
and
fourth instructions to associate at least the signature with an electronic device name or identifier that corresponds to the electronic device in the database.
