Abstract
The Present invention relates generally to processing audio or video content. In one embodiment, a method is provided including receiving audio or video content, the audio or video content includes a first watermark associated therewith, the first watermark has first data indicating that the audio or video content is rights protected; and associated a second watermark with the audio or video content, the second watermark including second data indicating permissible uses or restrictions associated with the audio or video content, wherein the second watermark is associated with the audio or video content later in time relative to the first watermark. Other embodiments are described and claimed as well.
Claims65
A method comprising:
- receiving audio or video content, the audio or video content comprising a first watermark associated therewith, the first watermark comprising first data indicating that the audio or video content is rights protected;
- and
- using at least a programmed electronic processor, associating a second watermark with the audio or video content, the second watermark comprising second data indicating permissible uses or restrictions associated with the audio or video content, wherein the second watermark is associated with the audio or video content later in time relative to the first watermark.
A method comprising:
- receiving audio or video content, the audio or video content comprising a first watermark associated therewith, the first watermark comprising first data indicating that the audio or video content is rights protected, the audio or video content further comprising a second watermark therewith, the second watermark comprising second data indicating permissible uses or restrictions associated with the audio or video content, wherein the second watermark is associated with the audio or video content later in time relative to the first watermark;
- and
- using a programmed electronic processor, associating a third watermark with the audio or video content, the third watermark comprising third data indicating permissible uses or restrictions associated with the audio or video content, wherein the third watermark is associated with the audio or video content later in time relative to the first watermark and the second watermark.
A method comprising:
- receiving audio or video content, the audio or video content comprising a first watermark associated therewith,
- the first watermark comprising first data indicating that the audio or video content is rights protected, the audio or video content further comprising a second watermark associated therewith,
- the second watermark comprising second data associated with a particular user or user device, wherein the second watermark is associated with the audio or video content later in time relative to the first watermark;
- detecting the second watermark to obtain the second data;
- and
- based at least in part on the second data, and using a programmed electronic processor, controlling reproduction of the audio or video content.
3 more elements
A method comprising:
- obtaining audio content, the audio content including elements to be audibly rendered to a user, where embedded data is conveyed along with the audio content;
- analyzing the embedded data for rights data, wherein the rights data is carried by a header;
- only if the rights data is missing, and using a programmed electronic processor, analyzing the embedded data for protect data that is contained within the elements to be audibly rendered to a user;
- and
- if the rights data is missing and the protect data is present, then restricting processing of the audio content.
2 more elements
An apparatus comprising:
- electronic memory comprising audio or video content, the audio or video content comprising a first watermark associated therewith, the first watermark comprising first data indicating that the audio or video content is rights protected;
- and
- an electronic processor programmed for associating a second watermark with the audio or video content, the second watermark comprising second data indicating permissible uses or restrictions associated with the audio or video content, in which the second watermark is associated with the audio or video content later in time relative to the first watermark.
An apparatus comprising:
- electronic memory comprising received audio or video content stored therein, the audio or video content comprising a first watermark associated therewith, the first watermark comprising first data indicating that the audio or video content is rights protected, the received audio or video content further comprising a second watermark therewith, the second watermark comprising second data indicating permissible uses or restrictions associated with the audio or video content, in which the second watermark is associated with the audio or video content later in time relative to the first watermark;
- and
- an electronic processor programmed for associating a third watermark with the received audio or video content, the third watermark comprising third data indicating permissible uses or restrictions associated with the audio or video content, in which the third watermark is associated with the audio or video content later in time relative to the first watermark and the second watermark.
An apparatus comprising:
- electronic memory for receiving audio or video content, the audio or video content comprising a first watermark associated therewith,
- the first watermark comprising first data indicating that the audio or video content is rights protected, the audio or video content further comprising a second watermark associated therewith,
- the second watermark comprising second data associated with a particular user or user device, wherein the second watermark is associated with the audio or video content later in time relative to the first watermark;
- detecting the second watermark to obtain the second data;
- and
- based at least in part on the second data
- an electronic processor programmed for controlling reproduction of the audio or video content.
4 more elements
An apparatus comprising:
- electronic memory for buffering obtained audio content, the audio content including elements to be audibly rendered to a user, where embedded data is conveyed along with the audio content;
- and
- an electronic processor programmed for:
- analyzing the embedded data for rights data, wherein the rights data is carried by a header;
- only if the rights data is missing, analyzing the embedded data for protect data that is contained within the elements to be audibly rendered to a user;
- and
- if the rights data is missing and the protect data is present, then restricting processing of the audio content.
4 more elements
A method of managing processing of video content, the video content including picture data representing picture elements to be rendered for display to a user, where embedded data is conveyed along with the video content, the method including:
- (a) examining the embedded data for rights data, in which the rights data is carried by a header;
- (b) only if the rights data is missing, and using a programmed electronic processor, examining the embedded data for protect data that is contained within the picture data;
- and
- (c) if the rights data is missing and the protect data is present, then limiting processing of the video content.
