Abstract
A reproducing apparatus having a function to recover synchronization and a function to display information. The first function resumes synchronous reproduction automatically even though synchronous reproduction is interrupted. The second function lets the user know what is going on in the reproducing apparatus when synchronous reproduction is interrupted.
Claims7
A reproducing apparatus capable of connection to an external display module, which comprises
- a first reproducing unit to reproduce data recorded in a disk-type recording medium,
- a connecting unit for connection to a network,
- a second reproducing unit to reproduce data transmitted from the network through said connecting unit while keeping connection to the network, and
- a control unit for control to display on said display module the data which said first reproducing unit reproduces and the data which said second reproducing unit reproduces, in synchronism with each other, wherein
- said control module displays a message on said display module informing an accidental status in which the data which said first reproducing unit reproduces and the data which said second reproducing unit reproduces cannot be displayed in synchronism with each other and also takes action to recover synchronization for synchronous reproduction.

A reproducing apparatus to reproduce information from a recording medium which comprises
- a reproducing module to read the first stream data from the recording medium,
- a network connecting module for connection to a network,
- a downloaded data memory module to store the second stream data which has been downloaded through the network,
- a reproducing module to reproduce the third stream data transmitted from the network,
- a user interface which is instructed by the user,
- a packet switching module to divide the packets in the entered stream according to the packet identification number and give out the divided packets, said packet switching module having at least three stream input terminals,
- a first buffer memory to temporarily store the stream entered from the first stream input terminal,
- a packet diving module to divide the packets given out from the first buffer memory according to the packet identification number,
- a second buffer memory to temporarily store the stream entered from the second stream input terminal,
- a third buffer memory to temporarily store the stream entered from the third stream input terminal,
- a selecting module to select those packets given out from said packet dividing module and those packets given out from said second and third buffer memories,
- an output terminal to give out those packets selected by said selecting module,
- a monitoring module to monitor the status of data accumulation in said first to third buffer memories, and
- a module to recover synchronous reproduction which recovers synchronous reproduction by setting said packet switching module according to the information acquired from said monitoring module when anomaly occurs in synchronous reproduction, in the case of synchronous reproduction by combination of at least two pieces of stream data from the first stream data reproduced from the recording medium, the second stream data reproduced from said downloaded data memory module, and the third stream data transmitted from said network, according to the user's instruction entered through the user interface.
