摘要:
A content reproduction device includes: a plurality of communication units (a cellular phone and a wireless LAN communication unit), each receiving a content transmitted in segments from a content transmission device over a communication path; a content reconstruction unit that has a buffer in which each segmented data of the content received by each of the communication units is temporarily accumulated, and that reconstructs each segmented data accumulated in the buffer into the content; a reproduction unit that reproduces, at a predetermined bit rate, the content reconstructed by the content reconstruction unit; and a communication control unit that: calculates, for every predetermined time, target transmission speeds to be assigned for content reception performed by the respective communication units, based on free space in the buffer and the bit rate; and transmits a first request signal indicating the calculated target transmission speeds to the content transmission device via one of the communication units.
摘要:
A transmission system includes a transmission apparatus and a receiving apparatus for repeatedly transmitting and receiving a frame with plural time slots at a constant frequency, in which digital audio data of plural channels and auxiliary data required to playback the digital audio data are transmitted using previously allocated time slots. A multiplexer is provided for multiplexing, assuming an area made up of previously allocated time slots that are included in respective frames amounting to a number of a multiple of n as block data when the predetermined encryption unit is n bytes. The digital audio data and the auxiliary data are allocated as the block data wherein the auxiliary data is allocated to the time slots that are located at the same positions of respective plural frames within the block data, and the digital audio data is allocated in the time slots that are located at the same position in the respective frames amounting to the number of a multiple of n in the block data. An encryptor encrypts at least the digital audio data from the multiplexed block data in the predetermined encryption unit and a communication unit transmits the data encrypted in the encryptor, wherein the receiving apparatus decodes the encrypted data transmitted from the transmission apparatus.

An on-vehicle recording/reproduction apparatus (700) of a data transmission/reception system includes: an extraction unit (502) which compares a database file (710) with a received database file (610) and extracts information regarding audio data recorded in a home recording/reproduction apparatus (600) but not recorded in the on-vehicle recording/reproduction apparatus (700); a sending unit which sends the audio data that is recorded in the on-vehicle recording/reproduction apparatus (700) but not recorded in the home recording/reproduction apparatus (600) and which is extracted by the extraction unit (502) to the home recording/reproduction apparatus (600); a delete determination unit (701) which determines whether to copy a song to the home recording/reproduction apparatus (600) or to delete the song from the recording unit (101) of the on-vehicle recording/reproduction apparatus (700) itself, by checking items “copy origin,” “copy destination,” and “priority level” in the database file (710).

[PROBLEMS] To provide an oxygen storage substance which has higher oxygen storage capacity than conventional substances and is inexpensive. [MEANS FOR SOLVING PROBLEMS] The oxygen storage substance is a calcium aluminosilicate (mayenite), i.e., a substance of a crystal structure which is synthesized by hydrothermally treating a mixture of calcium oxide, alumina (sol), and amorphous silica, has a three-dimensional network composed of AlO4 tetrahedrons and (Al,Si)O4 tetrahedrons in which part of the aluminum atoms have been replaced with silicon atoms, with vertex oxygen atoms being shared, and has oxide ions (O2−) occluded in microspaces in the structure. Part of the calcium atoms may be replaced with atoms of a transition metal, e.g., copper.

In a stream reception device, before the user operates an input section (15), a control section (12) uses locational information of each of n number of selected stream transmission stations (2) to generate and send a distribution request (R), which is data for requesting distribution of a stream (ST) stored in each of the stream transmission stations (2). Then, each stream (ST) is buffered in a stream storage section (14) sequentially from a reproduction start portion thereof. Then, in the case where a stream (ST) to be a target is stored, the control section (12) reads the target stream (ST) from the stream storage section (14), sequentially from the reproduction start portion thereof, and reproduces the target stream (ST), in response to an operation on the input section (15).

Separation of nitrogen and carbon dioxide is accomplished by a method using as a separating material one member selected from the group consisting of sepiolite in the unmodified form, sepiolite which has been heat-treated, and sepiolite which has had part or the whole of the exchangeable cation thereof replaced with zinc ion and which has been subsequently subjected to a heat treatment.
摘要:
A moving picture compressed signal changeover apparatus changes over from a first moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames to a second moving picture compressed signal containing intra-frame coded frames, forward prediction coded frames and bidirectional prediction coded frames such that a frame of the first moving picture compressed signal occurring just before an intra-frame coded frame or a forward prediction coded frame of the first moving picture compressed signal is connected to an intra-frame coded frame of the second moving picture compressed signal. A predetermined signal which is different from the first and second moving picture compressed signals may be inserted between the connected frames of the first and second moving picture compressed signals. Alternatively, at least one of the first and second moving picture compressed signals may be delayed so as to adjust a connecting timing.
