Embodiment Construction

[0031] Some embodiments designed according to the present invention will be described below with reference to the accompanying drawings.

[0032] FIG. 1 shows the configuration of a reproduction device designed according to one embodiment of the present invention. This rendering device is realized as a web client 21 which can communicate with the web server 11 . The Web server 11 and the Web client 21 are connected to a network 10 such as a home LAN (Local Area Network). The web server 11 functions as a server of a home network system. The network client 21 functions as a client terminal of a home network system.

[0033] The network server 11 includes a broadcast receiving unit 12 , a storage medium 13 and a network server processing unit 14 as shown in FIG. 1 . The broadcast receiving unit 12 is a receiving device that receives broadcast program data such as TV programs. The broadcast receiving unit 12 receives a digital broadcast signal such as a terrestrial digital bro...

Abstract

A reproduction apparatus includes a unit which receives a stream that is transferred from a server, a buffer which stores the received stream, a decoder which executes a decoding process for reading out the received stream from the buffer and decoding the received stream, a clock generator which generates a clock signal which determines a speed of the decoding process, a unit which determines whether the received stream is a real-time stream or a non-real-time stream, and a unit which executes a process for varying a frequency of the clock signal in accordance with a fill level of the buffer if the received stream is the real-time stream, and executes a process for setting the frequency of the clock signal at a fixed value if the received stream is the non-real-time stream.

Description

technical field [0001] The present invention relates to a reproducing device for reproducing compression-coded data and a decoding control method suitable for such a reproducing device. Background technique [0002] In recent years, a system has been developed that transmits data streams such as digital compression-coded audio / video (AV) from a server to a client through a network. In such a system, a real-time data stream such as broadcast data is transmitted from a server to a client through a network, for example. [0003] In addition, recently, there is a need for a technology that can transmit not only real-time data streams such as broadcast data but also non-real-time data streams that can be read from a storage medium at an arbitrary rate from a server to a client through a network. [0004] Japanese Patent Application Publication No. 2003-134468 discloses a digital signal processing device capable of decoding a transport stream output from a tuner and a program str...
