IM1HDMI 1.4a
This course covers the HDMI multimedia interface
Objectives
  • The course describes the architecture of a HDMI source-cable-sink system.
  • An introduction to Video and Audio standards is done prior to clarifying how this standards are transported through HDMI.
  • The analog interface is studied in detail, particularly the TMDS specification.
  • The course clarifies information coding / decoding schemes.
  • Content protection mechanisms are explained.
  • Ethernet connectivity and audio return channel are also covered.

  • This course has been delivered to several companies developing mobile phone chipsets.
A more detailed course description is available on request at training@ac6-training.com
  • Experience of a digital bus is recommended.
  • Theoretical course
    • PDF course material (in English) supplemented by a printed version for face-to-face courses.
    • Online courses are dispensed using the Teams video-conferencing system.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
  • Any embedded systems engineer or technician with the above prerequisites.
  • The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
  • Trainee progress is assessed by quizzes offered at the end of various sections to verify that the trainees have assimilated the points presented
  • At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
    • In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
