摘要:
A method of embedding copyright management information in AV content distributed in a downloadable file format is provided. In the MP4 file format, which is a format for distributing downloadable files, content data is separated by code into a general stream and an IPMP-controlled media stream. A box for embedding data required for IPMP initialization and a box for embedding data required to interpret IPMP protection and related parameters are rendered in a first box that is rendered in the control data box.
摘要:
A data distribution system that distributes data adapting to a second terminal from a first terminal having data to the second terminal. The first terminal includes a data recording means that records data of a plurality of formats, a data distribution request receiving means that receives a distribution request of data adapting to the second terminal and that receives a URL related to the information of the second terminal, a terminal information acquiring means that acquires the information of the second terminal from the URL, a data selecting means that selects data adapting to the second terminal on the basis of the acquired information of the second terminal, and a data transmitting means that transmits the selected data to the second terminal. The second terminal includes a terminal information describing means that describes the information of the second terminal in tree structure, a URL recording means that transmits the information of the second terminal described in tree structure to a predetermined URL to record the information, a data distribution request means that requests the first terminal to distribute data adapting to the second terminal and that notifies the first terminal of the URL, and a data receiving means that receives the data from the first terminal.
摘要:
The invention is related to Digital Rights Management (DRM) or Intellectual Property Management and Protection (IPMP) for a generic digital content. The concept of IPMP Control Graph and REL-IPMP Control Graph is introduced to carry protection signalling and rights expression data. Both content packaging and terminal processing relating to the above control graph are clearly defined and elaborated.

The invention provides an intelligent close loop recognition restoring feedback device including a back plate, a casing is disposed at a side of the back plate, and a covering plate is disposed on the casing. A rotating pivot is protruded from the middle of the covering plate and the middle of the casing. Two transverse rotating handles are disposed at an end of the rotating pivot, and the rotating handles are fixed by a plug cover. Two moving-sliding blocks are disposed in the casing, and the two moving-sliding blocks are connected to each other via tensile elastic elements. A cam is disposed between the two moving-sliding blocks, and each moving-sliding block is provided with a cylindrical pin. The two cylindrical pins are located at the same position on the moving-sliding blocks and abut against the edge of the cam. In the invention, the structure of the device is concise, and the device may easily detect the real-time operation conditions and reflect the message about whether the operation is right to the operator, and may prevent the operator from continuing operating the infusion transferring system under improper conditions. As a result, the safety of the device is guaranteed.

A receiver, which receives an ISMA media stream that is MPEG-4 IPMP-expanded, is provided with processes of: receiving an ISMA media stream containing an ISMA head, contents and an IPMP tool list descriptor that indicates a method for processing the contents; acquiring the IPMP tool list descriptor from the ISMA media stream; making an inspection as to whether or not the tool indicated by the IPMP tool list descriptor is present in the receiver; and when the tool is present, processing the contents by using the tool, while, when the tool is not present, completing the processes without causing any failure.

This invention provides an angle rotation controlling device including a main pole, a left arm and a right arm which are rotatable around the axis of the main pole are assembled on the main pole. A vertical rod is assembled at an end of the left arm and right arm, respectively, and a left arm tooth disc is assembled at the left arm's end which is coaxial with the main pole. The right arm tooth disc matched with the left arm tooth disc is assembled at the right arm's end which is coaxial with the main pole. The left arm tooth disc and the right arm tooth disc are assembled on the main pole via a knob. A main pole tooth disc is fastened at the bottom of the main pole to cooperate with the left arm tooth disc. The angle rotation controlling device can not only make the left arm and the right arm rotate relatively, but also can make them rotate around the main pole while keeping them relatively stationary. The height can be adjusted at will, which allows doctors and nurses to move the patients conveniently.

A sea water desalinating system with jetting cavitational technology includes a sea water collecting device for collecting sea-water, a water transmitting pump communicated with the collecting device, a coarse filtering device communicated with the water transmitting pump for filtering impurities, a fine filtering device communicated with the coarse filtering device for further filtering, a booster pump communicated with the fine filtering device for further transmission, at least one jetting cavitational device communicated with the booster pump for sterilizing, flocculating, and preventing scale, a sea water desalination device communicated with the jetting cavitational device for desalinating the sea water, and a fresh water storing device communicated with the sea water desalination device for storing fresh water got from the system.
摘要:
A power amplification circuit having three modes of operation and a single switch is disclosed. Only one switch is used to control three different load impedance levels, one load impedance level for each mode of operation. The remaining “switching” results from selectively biasing each power amplification path by turning ON or OFF amplifiers. A series L-C and a switch are used to control the load impedance. Additional modes of operation may also be created without requiring any additional switch. Further, multiple modes of operation may be implemented using no switches.
