Abstract
An SDI signal discriminating apparatus for discriminating the type of an SDI signal. The SDI signal type discriminating apparatus comprises an HD-SDI type detector which generates an HD lock signal HD_LOCK when it detects a first periodic component included in an HD-SDI signal in the received SDI signal, and an SD-SDI type detector which generates an SD lock signal SD_LOCK when it detects a second periodic component included in an SD-SDI signal in the received SDI signal. The first periodic component differs in period from the second periodic component.
Claims16
An SDI signal discriminating method for discriminating a type of a received SDI signal, comprising:
- a first detecting step of detecting in the received SDI signal a first periodic component included in a first type of SDI signal to generate a first type detection signal indicating detection of the first type of SDI signal;
- and
- a second detecting step of detecting in the received SDI signal a second periodic component included in a second type of SDI signal to generate a second type detection signal indicating detection of the second type of SDI signal, said second periodic component being different in period from said first periodic component.
An SDI signal discriminating apparatus for discriminating a type of an SDI signal, comprising:
- first detecting means connected to receive an SDI signal for generating a first type detection signal when said first detecting means detects a first periodic component included in a first type of SDI signal;
- and
- second detecting means connected to receive the SDI signal for generating a second type detection signal when said second detecting means detects a second periodic component included in a second type of SDI signal, said second periodic component being different in period from said first periodic component.
