4.7Option-1 Licensable CodecsFor several meetings, MPEG had discussions on Option-1 licensable codecs. Especially small companies consider the per-stream licensing fees as cumbersome. At its 91st meeting, MPEG issued document N11221 Possible future actions on standardization with Type 1 licensing where the legal issues are summarized and discussed. Type 1 licensing refers to option 1 of the joint patent declaration form, where an intellectual property holder can indicate that he will not charge for his IP. Laymen refer to this type of licensing as royalty-free. In order to finalize the discussion MPEG issued a resolution at the 92nd meeting related to royalty-free video codecs. Until this 93rd meeting, the CH, CN, IT, KR, and UK NB indicated support. No input document on this support was received. The FR and US NB indicated that they have no resources available. Given that the minimum resources for a new work item is available, MPEG decided to further explore this type of standard. In response to N11533 Call for Evidence on Option-1 Video Coding Technology, MPEG received 2 late inputs from Oracle (US NB), Peking University, Tsinghua University, and Zhejiang University (CN NB). One proposal included the full set of coded video sequences. During this meeting, these sequences were evaluated in an informal subjective test. Compared to MPEG-1, a noticeable improvement in subjective quality and an objective improvement of 1db to 4 db was observed. Comparisons against other standards like VP8 were not available. Given that the proponents envision further improvements of their codecs, a second call for evidence N11676 Call for Evidence on Option-1 Video Coding Technology was made. The due date is the 95th meeting. The adhoc group N11685 AHG on Evaluation of Responses to the Call for Evidence prepares the evaluation. No progress was made with respect to the working guidelines for developing an Option-1 licensable codec. Between the 93rd and 94th MPEG meeting, an indefinite moratorium on airtime fees for Internet video that is free for end users was announced by MPEG LA. Therefore, MPEG asks its members whether there is still a need to develop a type-1 licensable codec and what its performance requirements are. 4.8User IdentificationIn many applications relevant to MPEG standardization, an identification of individual users or a description of users may be desirable. Currently, a user description in the context of MPEG-V is under investigation. A more focused and all-embracing effort related to user identification might be required. This identification of users may be useful for content adaptation and for exploitation of user preferences. Obviously, such an user identification bears some risks related to privacy. The Requirements subgroup kindly encourages organizations to provide input on user identification/description.
