This private branch exchange includes a park portion capable of parking a call put through to a telephone terminal unit via a terminal connection portion and a control portion controlling the park portion, when a nuisance call from the public telephone network is put through to the telephone terminal unit via the terminal connection portion, to park the nuisance call on the basis of a prescribed operation of the user against the nuisance call.

Private branch exchange, VoIP gateway unit and private branch exchange system

A networking apparatus including a PBX that relays between and manages IP and analog telephones that are assigned extension number information has: a VoIP conversion portion which converts an analog audio signal into an IP signal; an IP connection portion to which an IP telephone is connected; and an analog connection portion to which an analog telephone is connected. When a call originated from an IP or analog telephone is relayed and connected to an analog telephone, extension number information of the call originator is output to the analog telephone.

Networking apparatus and telephony system

A communication apparatus includes a first storage portion storing an address control table registering a MAC address which each of a plurality of communication devices connected to the same local area network has, a comparison portion distinguishing each of the registered MAC addresses by comparing the MAC addresses corresponding to the plurality of communication devices registered in the address control table sequentially in a bit-by-bit manner until the MAC addresses can be distinguished from each other and a control portion determining whether or not data transmitted in the local area network is acquired on the basis of a comparison result.

Communication apparatus and communication system

A broadcast receiving device comprising: a memory unit for storing a receivable channel information; a determination-information acquiring unit for acquiring determination information to identify a predetermined transmission condition of the transmission path; a determining unit for determining whether the transmission condition has varied, based on the determination information acquired by the determination-information acquiring unit; a detecting unit for detecting a channel of broadcasting signals which are receivable, by conducting an automatic scanning when the determining unit determines that the transmission condition of the transmission path has varied; and a renewing unit for renewing the channel information stored in the channel memory unit, based on a detected result obtained by the detecting unit.

An image processing device is provided with a picture quality mode which is used to collectively set a plurality of the picture qualities by one operation, a user can select the picture quality mode depending on his preference or content of programs to be viewed. A recording portion stores an association table. The association table is a table in which the picture quality mode and sound quality setting values to direct sound quality setting for a sound quality setting portion, are correlated with each other and stored. When a control portion receives a picture quality setting command by a designation of the picture quality mode, the picture quality setting portion performs setting of the respective picture qualities depending on the picture quality mode. Further, the setting direction portion reads out the association table and obtains the sound quality setting values which are correlated with the designated picture quality mode. Then, sound quality setting is performed by giving the obtained sound quality setting values for the sound quality setting portion.

Image processing device

A television broadcast signal receiving apparatus includes a receiving unit, a control unit and a display control unit. The receiving unit is configured to receive a plurality of audio-video signals. The control unit is configured to receive operation inputs. The display control unit is configured to display images corresponding to the audio-video signals on a main screen and a subscreen in a display component at the same time. The display control unit is further configured to display an image corresponding to one of the audio-video signals, which has been displayed on the subscreen, on the main screen when the control unit receives an operation input to output audio corresponding to the one of the audio-video signals.

An error correction apparatus and an error correction method according to the present invention can reduce an entire lead-in time of a demodulation system by reducing a lead-in time for deinterleave mode judgement, which greatly affects the entire lead-in time of the demodulation system. This error correction apparatus employs an output signal (perror) from a Reed-Solomon decoding unit that is connected outside of a deinterleave unit, as a trigger for changing deinterleave modes (dimode).

Apparatus and method for error correction

A convolutional interleaver performs convolutional inerleaving for a data group in which the input/output data width is b bits, the depth, i.e., the number of data in bit width units, is m, the number of channels is n, and the maximum channel number is C (n&equals;integer satisfying the relation 0&lE;n&lE;C, b,m,C&equals;natural number). This interleaver includes a delay unit comprising first and second delay units and performing a delay of n&tgr; for data of the n-th channel (T&equals;a predetermined amount of delay, T>0) The first delay unit performs a delay of is (S&equals;a predetermined amount of delay, 0<S&lE;T) for the i-th group amongst groups into which all the channels are grouped such that each group comprises at most k channels, and the second delay unit performs a delay equivalent to a deficiency in the delay of the first delay unit for the delay of nT to be given to the data of the n-th channel. Therefore, delays to be commonly generated between channels in each group are generated together by the first delay unit, and delays including differences in delays between the channels are individually generated by the second delay unit, whereby control and structure of the delay means can be simplified.
