Abstract: Disclosed is a communication line connecting adapter which adequately connects an ordinary telephone, IP phone and modem/facsimile machine to a connecting party. The adapter comprises first to third switches, a line which connects a common terminal of the first switch to the modem/facsimile machine via a first DAA circuit, a line which connects a zeroth node terminal of the first switch to a public telephone line and a common terminal of the second switch, a line which connects a first node terminal of the first switch to a VoIP gateway via an SLIC, a line which connects the first node terminal of the first switch to a zeroth node terminal of the third switch, a line which connects a zeroth node terminal of the second switch to the VoIP gateway via a second DAA circuit, a line which connects a first node terminal of the second switch to a first node terminal of the third switch, and a line which connects a common terminal of the third switch to an extension line.

Abstract: An audio playback/recording apparatus includes an audio input processing section which receives analog audio data, and converts the analog audio data to digital audio data; a playback/recording processing section which compresses digital audio data output from the audio input processing section and stores the compressed digital audio data into a RAM and which decompresses the compressed digital audio data according to attribution data indicating a type of compression; an audio output processing section which receives the decompressed digital audio data, converts the decompressed digital audio data to analog audio data, and outputs the analog audio data to an output apparatus; and an external recording circuit section which records compressed digital audio data stored in the RAM into an external recording medium, reads out the compressed digital audio data, and stores the data into the RAM.

Abstract: In a content information processing apparatus including a content information inputting section, a content information storage section, a content information reproducing section, and a content information storage section controlling section, the content information storage section substantially time-divisionally carries out a recording operation upon input content information inputted from the content information inputting section for the storage section and a reproducing operation upon output content information in the storage section for the reproducing section.

Abstract: An image processing display apparatus for converting an image signal of an interlace system into a progressive scanning system and displaying an image, having means for conducting low band frequency passing processing so as to reduce flicker for a vertical direction signal component of a still picture signal component included in a video image signal, and means for synthesizing a still picture signal component to which the low band frequency passing processing is applied and a moving picture signal component included in the above-described video image signal to generate a progressive signal.

Abstract: An audio playback/recording apparatus comprising: an audio input processing section 11, which receives analog audio data, and converts the analog audio data to digital audio data; a playback/recording processing section 12, which compresses digital audio data output from the audio input processing section 11 and stores the compressed digital audio data into a RAM 16, and which decompresses compressed digital audio data stored in the RAM 16; an audio output processing section 13, which receives decompressed digital audio data output from the playback/recording processing section 12, converts the decompressed digital audio data to analog audio data, and outputs the analog audio data to an output apparatus; an external recording circuit section 18, which records compressed digital audio data stored in the RAM 16 into an external recording medium 18A, reads out compressed digital audio data output from the external recording medium 18A, and stores the data into the RAM 16.

Abstract: An MPEG coded picture decoding apparatus is provided which can display video data quite the same as original data even if a miss of MPEG coded video data occurs in a transmission line or the like.

Abstract: A biasing voltage is supplied from the emitter of an emitter follower npn transistor. The base current of the npn transistor is supplied from the emitter of an emitter follower pnp transistor. Thus, a constant biasing voltage which is not influenced by an average value of an input signal, is supplied to an amplifier.
