Dharun Ravi appeared in state court to formally put on the record his decision to report to jail Thursday and waive his right not to be punished twice for the same crime.
His lawyer, Joseph Benedict, said Ravi intends to begin doing community service when he's out of jail, and will start paying fines on Aug. 1.
The state's appeal of Superior Court Judge Glenn Berman's sentence as too lenient had automatically stayed the sentence. Prosecutors were seeking to have Ravi sent to state prison rather than county jail -- though not necessarily the 10-year maximum sentence Ravi faced for bias intimidation.
But Ravi announced Tuesday he had decided to start his jail term despite the appeal. He also issued his first public apology while continuing to deny his actions were motivated by hate or bigotry.
Ravi was convicted in March of bias intimidation, invasion of privacy and other crimes for the watching a brief live webstream of roommate Tyler Clementi kissing another man in September 2010. Clementi threw himself from New York City's George Washington Bridge days later after learning of the webcam.
Gay rights advocates held up Clementi an example of the consequences of bullying. Ravi's supporters say Ravi was not a bully at all, but a college student who made a bad decision -- and that the charges were so serious only because of Clementi's suicide -- even though Ravi was not charged with his death.
In his apology issued through a lawyer on Tuesday, Ravi, 20, described his actions as "thoughtless, insensitive, immature, stupid and childish."
He said getting his jail term out of the way is "the only way I can go on with my life."
Because Ravi's sentence is less than a year, it decreases the chances that federal immigration authorities will seek to have him deported to India, where he was born and remains a citizen.
