A method and apparatus for providing 3D still image service in a specific time interval during audio-visual service of digital broadcast are provided. The method includes receiving a reference image and a 3D supplement image, which construct a 3D still image, through a data channel or a video channel together with a 2D image; restoring the reference image and the 3D supplement image to the 3D still image; and displaying the 3D still image in a specific interval during digital audio-visual broadcast using the 2D image according to display information which includes a play time and a play mode.
摘要:
Methods and apparatuses for encapsulating inorganic micro- or nanostructures within polymeric microgels are described. In various embodiments, viruses are encapsulated with microgels during microgel formation. The viruses can provide a template for in situ synthesis of the inorganic structures within the microgel. The inorganic structures can be distributed substantially homogeneously throughout the microgel, or can be distributed non-uniformly within the microgel. The inventive microgel compositions can be used for a variety of applications including electronic devices, biotechnological devices, fuel cells, display devices and optical devices.

摘要:
A method for transmitting variable length packets based on FEC coding. Data packets are successively and contiguously stored in a two-dimensional storage device. FEC coding is performed to generate parity packets. The parity packets are stored in the two-dimensional storage device. The data packets, offsets representing positions of the data packets in the two-dimensional storage device, types of packets, and the parity packets are then transmitted.
