Abstract: A content receiving apparatus has: a communicating unit connecting to a server; a reception buffer receiving and storing transmitted content data; a content reproducing unit reproducing the read-out content data; a controller controlling the communicating unit and the reception buffer; and an operating unit supplying an operation signal to the control unit. The data reception and the data output to the reproducing unit from the buffer are stopped by a reproduction temporary stop instruction. The data reception is restarted by a reproduction temporary stop cancellation instruction. The received content data is written into the buffer. The reception of a disconnection signal from the server is discriminated after the restart of the data reception. If the signal is not received, a predetermined amount of received data is written into the buffer, the reading is started, the data is outputted to the reproducing unit, and the reproduction is restarted.

Abstract: A recording system is constructed with at least first and second recording devices, both of which are connected to a network and have channel selection functions and functions of reserving the recording of broadcast program information forming a broadcast program. The first recording device includes a first memory for storing recording reservation information from a user, a judgment circuit for judging whether the recording reservation information is for a receivable broadcast channel, and a sending circuit for producing a recording reservation request containing the recording reservation information and for sending it to the network when it is judged that the recording reservation information is not for a receivable broadcast channel.

Abstract: A recording system having a plurality of recording apparatuses connected to a network. The apparatuses can select a channel for receiving a broadcast signal and record reservations for recording a program broadcast through a broadcasting channel at a predetermined time of day. One of the apparatuses, denoted as a reservation-receiving recording apparatus, receives recording reservation information from a user and detects if there is any overlapping programs in time using received recording reservation information and prexisting recording reservation information stored in memory. The reservation-receiving recording apparatus sends to the network a recording reservation request including overlapping recording reservation information, if it detects broadcasting time period overlaps, wherein the overlapping recording reservation information causes the overlapping program to be recorded by another recording apparatus connected to the network instead.

Abstract: A mutual recognition process is performed in step S1. When it is determined in step S2 that a request for sending a list of musical pieces has been received, the list of musical pieces is sent in step S3. When a request for sending audio data has been received in step S4, a transfer-rate measurement process is executed in step S5. When it is determined according to the transfer rate in step S6 that the audio can be transmitted, the corresponding compressed audio data is extracted in step S7, the compressed audio data is decoded to generate linear PCM data suited to the transfer rate in step S8, and transmitted in step S9. When the audio data cannot be transmitted, an error message is transmitted in step S10. The present invention can be applied, for example, to a server for distributing audio data and an audio player terminal for reproducing the distributed audio data.

Abstract: A first playback device, upon receiving a synchronized playback command while content playback is in progress, transmits, to a second playback device, information that pertains to the playback content and a synchronized playback start time obtained by adding a predetermined additional time to an elapsed playback time for the content. The second playback device starts receiving content data that begins from the synchronized playback start time from a server. After the data that is memorized in a memory reaches a specified volume, the second playback device transmits a playback preparation completion notification to the first playback device. Once the elapsed playback time for the content reaches the synchronized playback start time, the first playback device transmits a playback start command to the second playback device. Upon receiving this command, the second playback device starts playing back content data that begins from the synchronized playback start time.
