This proposal responds to 3.3.1 Video-on-Demand service attributes in CFP. (mainly Access contorol and user profile, Billing/charging, Cotent management) We propose the minimum conditions that should be supported by systems in order to guarantee the quality of VOD services provided to users. It is necessary to specify quality from a wide range of viewpoints. Quality aspects should be treated on a second level with a higher-level set of specifications. Concrete parameters for the minimum specifications and the high-level viewpoint specifications are proposed in the following. Specifically, (1)Considering the privacy of users, we have proposed a protection level for user profiles (user ID, terminal class, password, age, sex, name, address, phone number). We propose that connection times and charge details are recorded with privacy protection. (2)We define the quality of contents and intellectual property protection to make it easier for CPs (contents providers) to provide contents. We have also proposed a definition for the delivery quality of contents to allow safe usage by users. ・We propose limiting the bit rate of the MPEG1 video component in VOD signals up to 4 Mbit/s. (3)To clarify the conditions that the STUs should satisfy when there is a fault in the server, we propose definitions for the on-demand quality (response time, picture quality) and the system-down influence level (time to recovery, recovery level). ・Considering the interface with the STU, the Time-Out of the response from the Server is taken to be 60 seconds.
