Hi everyone, I'm currently investigating some audio-codecs used in radio-broadcasting. Apart of the technical issues involved there is obviously the topic of licencing. On the MPEG FAQ I found a contact at Philips for MPEG layer 2: w.l.vanderkruk@patents.corp.philips.com Unfortunately this email-address / mail-server does not seem to exist anymore. Does anyone here have any pointers where I could try to go next to receive more information about the licencing schemes for this codec? On top of this I'm also interested in the AAC low delay. Who is licencing the IP for this codec? Thanks in advance for your responses... Best regards, Tobias

Try shortening the domain name; to "phillips.com." for example. There is likely to be someone at the company who knows. The hard part is finding someone who will connect you to that person.

Another audio-codec which is widely used in the industry is apt-x. Their website is www.aptx.com Tobias Erichsen wrote:> Hi everyone, > > I'm currently investigating some audio-codecs used in radio-broadcasting. > > Apart of the technical issues involved there is obviously the topic of > licencing. > > On the MPEG FAQ I found a contact at Philips for MPEG layer 2: > w.l.vanderkruk@patents.corp.philips.com > > Unfortunately this email-address / mail-server does not seem to exist > anymore.
