A technical probe has found that the pornographic image that emerged on screen in the House chamber during the charter amendment debate last Wednesday was not transmitted by parliament audio-visual staff.
Deputy House secretary-general Khamphi Ditthakorn yesterday invited experts from CAT Telecom and parliament IT officials to investigate the April 16 incident.
The experts checked smartphones and tablets of various brands, including iPhones, Samsung Galaxy Notes, Samsung Galaxy Tabs and iPads. Parliament audio-visual staff smartphones and mobile phones were also checked.
Initial results of the one-hour technical investigation showed that no House employees' mobile phones or communication devices could have sent photo files to the plasma screen displays in the House chamber, said a source.
The probe found iPads and iPhones could not directly send the transmissions of pictures to the screen even though the devices had the LGTV Remote application, a Wi-Fi remote controller. The iPads and iPhones would have asked for a password before sending a picture in that manner, said the source.
Samsung Galaxy Notes and Samsung Galaxy Tabs would have been capable of sending signal transmissions to the plasma screen by using an "all share" programme installed on the devices without the need for a password. The transmissions of pictures takes about five seconds, said the source.
The experts tested the transmission signals of the two Samsung devices and found that both Samsung Galaxy Notes and Samsung Galaxy Tabs could transmit data files to the plasma screen in the House chamber.
However, the phone numbers of the senders could not be checked as the files were sent via a Wi-Fi system, said the source.
Democrat Party leader Abhisit Vejjajiva said the party was willing to let the House committee on parliamentary affairs investigate Democrat MP for Bangkok Nat Bantadtan for looking at a pornographic image while parliament was in session.
Mr Abhisit said he had asked Mr Nat to fully cooperate with the House panel.
Mr Nat was caught by an unnamed photographer looking at a pornographic picture on his smart phone during the charter amendment bill debate in the House last Wednesday. The incident occurred on the same day that the picture of the half-naked woman popped on the giant screen, shocking MPs.
Mr Abhisit said the Democrat Party welcomed the House panel's probe and would not interfere with its work.
If Mr Nat is found guilty, the party would take action against him, Mr Abhisit said.
