ASSOCIATING FIRST AND SECOND WATERMARKS WITH AUDIO OR VIDEO CONTENT
First Claim
1. A method comprising:
- obtaining data representing audio or video content;
using an electronic logic processor, embedding a protect watermark in the data, the protect watermark providing an indication that the data is protected;
using an electronic logic processor, embedding a rights watermark in the data, the right watermark providing an indication of user rights associated with rendering the audio or video content, in which the protect watermark is more difficult to remove from the data relative to the rights watermark; and
reproducing the audio or video content after said acts of embedding a protect watermark in the data and embedding a rights watermark in the data.

Abstract
The present invention relates generally to processing audio or video content. One claim recites an apparatus comprising: electronic memory, and an electronic logic processor. The electronic memory is for storing data representing audio or video content, in which the data includes a protect watermark embedded therein, the protect watermark providing an indication that the data is protected, and in which the data further includes a rights watermark embedded in the data, the right watermark providing an indication of user rights associated with rendering the audio or video content, the protect watermark being more difficult to remove from the data relative to the rights watermark. The electronic logic processor is programmed for analyzing the data to retrieve the protect watermark only when the rights watermark does not exist in the data. Other claims are described and provided as well.
