Formula (1) 85&#xb0; C.&#x2266;Y&#x2266;92&#xb0; C. Formula (2) 35&#xb0; C.&#x2266;Y&#x2212;X&#x2266;50&#xb0; C. Formula (3) where X is an onset temperature and Y is an endset temperature of an endothermic peak on a differential scanning calorimetry (DSC) curve of the toner as measured by a differential scanning calorimeter (DSC).

Toner and developer

A toner including base particles each containing a crystalline polyester and a non-crystalline polyester, wherein the toner has a glass transition temperature of 45&#xb0; C. or higher where the glass transition temperature is determined from a DSC curve of the toner obtained in the first elevation of temperature thereof, and wherein the toner has a temperature width of 8&#xb0; C. or lower where the temperature width is a temperature width at &#x2153; the height of an endothermic peak attributed to the crystalline polyester in the DSC curve.

There is provided a receiving device including: a receiving unit that receives a packet stream; an oscillator; a measuring unit that performs a measuring operation; an acquiring unit that reads the newest time stamp read from the packet stream received by the receiving unit and the newest measurement value measured by the measuring unit with a predetermined period, from a point of time when the packet stream starts to be received; a calculating unit that calculates an accumulation value of the time stamps and the measurement values acquired by the acquiring unit; a comparing unit that compares a difference between the accumulation value of the time stamps and the accumulation value of the measurement values calculated by the calculating unit, and a value corresponding to a network jitter; and a frequency control unit that controls the oscillation frequency of the oscillator based on the comparison result by the comparing unit.

Receiving device, clock synchronizing method, and computer program

A data stream inputted to the inventive system from the outside is supplied to a PID (packet ID) extracting circuit, in which a PID is detected from a transport stream TS regardless of whether the transport stream TS is a full transport stream TS or a partial transport stream TS. The PID extracting circuittransmits the thus extracted PID and data stream to a TS replacing/deleting circuit. The TS replacing/deleting circuithas n 188-byte buffers and is able to set replaced TS packets to the buffers. A control circuitsuch as a CPU (central processing unit) designates m PIDs relative to the respective buffers and designates the respective PIDs as the PID of the packet to be deleted or the PID of the packet to be replaced. Then, the TS replacing/deleting circuitcompares the PID received from the PID extracting circuitwith the PID designated by the control circuit. If they are identical to each other, then the PID that is set to be replaced is replaced and the PID that is set to be deleted is deleted. Thus, the packet indicative of attribute of data can be replaced satisfactorily.

Signal processing apparatus and associated methodology for controlling the recording of data streams

FIG.B shows buffer occupancy rate of a transport stream bufferwhen a TS packet is transferred to the transport stream bufferhaving a transport rate Rt and a leak rate Rx. A time Tduring which the buffer occupancy rate of the transport stream bufferincreases and a time Tduring which the buffer occupancy rate of the transport stream bufferdecreases are expressed by (Rt&#x2212;Rx)&#xd7;T=Rx&#xd7;Tand T=(188&#xd7;8)/Rt. A time T is T=T+T=(188&#xd7;8)/Rx. Therefore, the time T is equal to a time T' shown in FIG.C. Thus, when a TS packet is transferred in a cycle of the time T&#x2032;, the transport stream bufferwill not overflow and the transport stream bufferbecomes empty at least once a second, whereby simulation for the transport stream bufferis not required in the simulation for the T-STD model.

Data multiplexer, data multiplexing method, and recording medium

An encoder considers a frame representing a picture as comprised of areas. For each area, the encoder decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area. For each area, the encoder decides which of frame-based or field-based predictive encoding will be most efficient at reducing temporal redundancy in that area. The encoder encodes each area of the picture frame using the most efficient orthogonal transformation technique and using the most efficient predictive encoding technique to produce an encoded signal. A decoder decodes the encoded signal. The encoded signal is recorded on a recording medium, transmitted over a transmission channel, or broadcast.

Picture signal coding method and picture signal coding apparatus, and

An apparatus for coding a moving picture in which one frame is comprised of two fields, includes a coder such that, with respect to all blocks in a frame, the odd field (the first field) and the even field (second field) are divided into blocks, thus permitting motion prediction of the second field from the first field, a coder means adapted for switching, every macro block, whether or not a frame is divided into the first field and the second field to generate block data to adaptively switch these coders every frame, thereby making it possible to obtain a picture of a high picture quality with a lesser quantity of information, to reduce the scale of hardware, and to reduce the capacity of a decoder.

Efficient coding apparatus for picture signal and decoding apparatus

In an encoder, an input picture of a non-interlace structure is sampled by down sampling to form an interlace picture, and the interlace picture is encoded. The encoded data are decoded to form an interlace decoded picture, and the interlace decoded picture is sampled by up sampling and utilized as a predictive picture upon encoding of the non-interlace input picture. In a decoder, a bit stream corresponding to an interlace picture of a low resolution is decoded into an interlace decoded picture. The interlace decoded picture is sampled by up sampling and is utilized as a predictive picture upon decoding of a bit stream corresponding to a non-interlace picture of a high resolution.
