An audio-on-demand communication system provides real-time playback of audio data transferred via telephone lines or other communication links. One or more audio servers include memory banks which store compressed audio data. At the request of a user at a subscriber PC, an audio server transmits the compressed audio data over the communication link to the subscriber PC. The subscriber PC receives and decompresses the transmitted audio data in less than real-time using only the processing power of the CPU within the subscriber PC. According to one aspect of the present invention, high quality audio data compressed according to lossless compression techniques is transmitted together with normal quality audio data. According to another aspect of the present invention, metadata, or extra data, such as text, captions, still images, etc., is transmitted with audio data and is simultaneously displayed with corresponding audio data. The audio-on-demand system also provides a table of contents indicating significant divisions in the audio clip to be played and allows the user immediate access to audio data at the listed divisions. According to a further aspect of the present invention, servers and subscriber PCs are dynamically allocated based upon geographic location to provide the highest possible quality in the communication link.

A system, method and computer-readable code for segmenting an audio stream into a plurality of small digital audio files using gaps in the natural language of the audio stream is provided. The small digital audio files are transmitted, loaded, and played in a specific order, such that from the user's perspective, the audio stream is reproduced in an apparently seamless manner. This is done without reassembling the audio stream, either in whole or in part. The small digital audio files are created using natural language gaps, and are generally small enough to ensure that a first small digital audio file can be downloaded and played without significant delay, while successive small digital audio files are downloaded to be played in the future. Accordingly, the user receives audio-on-demand in a timely manner.

The present invention provides IP-centric, multi-channel, time-shifted and real-time telecommunications services to a plurality of system users. The system can capture both digital and analog multi-channel feeds and, through a cross-connect layer, can convert the signals to a digital format and subsequently send them to an encoder to be compressed. The encoding process can use a firmware upgradeable software developed to decrease data bitrates while retaining quality of the information at a desired level. The encoded, compressed signals may either be stored on a data-on-demand server for later viewing services, such as television / video-on-demand or audio-on-demand, or may be streamed directly to system users using a Media Streaming Subsystem (MSS). The M'SS can be responsive to a system user request and operative to forward a selected stream of compressed digital data to the system user via a gateway means. The system can include a System Controller that can provide management and control of the system components and services provided by the system. The gateway means is able to receive compressed digital data from the Media Streaming Subsystem and transmit that data to a system user sending a request over a communication network. A cable modem, DSL modem or other appropriate interface can be located at each system user's location, thereby providing a means for sending multiple signal sources to a system user's Local Area Network (LAN) to which the User Computing Device(s) (UCD) of a system user are connected. The UCD receives the compressed data from the gateway means, subsequently decodes this compressed data and presents this decompressed information to the system user via a presentation system which may or may not be integrated into the UCD, thereby providing the requested entertainment services to the system user.

The invention discloses a method and a device for realizing audio-on-demand through an intelligent radio. The method comprises the following steps of receiving an audio-on-demand message which is sent by a second terminal with a first control right of the intelligent radio, wherein the audio-on-demand message carries a playing channel and playing time of on-demand audio; and controlling the intelligent radio to receive the audio within the playing time through the playing channel according to the audio-on-demand message. According to the technical scheme, the timing playing can be realized, a problem of limited request program time in the correlation technique is avoided, and the second terminal assigns a first terminal as an on-demand object, so that the privacy of audio-on-demand is improved.

The invention discloses a method for audio data transcoding. The method comprises the steps that EPG (electronic program guide) information of audio data stream to be collected is obtained; an audio signal is collected from an equipment interface corresponding to an equipment channel according to the equipment channel arranged in a preset configuration file; the audio signal is encoded into audio data with a preset format according to a coding format and coding parameters arranged in the preset configuration file; and the audio data is stored as an audio program file according to a transcoding audio data file storage position, a naming rule and the EPG information arranged in the preset configuration file. According to the technical scheme, the collected audio data can be independently stored in a server and used for audio on demand in the form of program according to the preset configuration file and the EPG information, and the collection and transcoding efficiency of the audio data can be improved. The invention also discloses a device and a transcoding server for implementing the method.

The invention provides a video on-wall configuration method for an analog TV wall. The method comprises the following steps that a client sends a video on-wall command to a command processing server, and the command processing server forwards the video on-wall command to a video and audio controller; the video and audio controller receives the video on-wall command, forwards a video and audio on-wall command to an Rtsp (real time streaming protocol) server, and also requests a streaming media server to provide a video and audio on demand service; the streaming media server receives the request and then sends a high-bit-rate video and audio stream to the Rtsp server, and then the Rtsp server sends the high-bit-rate video and audio stream with an Rtsp protocol and a control stream to a data matrix or decoder, and the high-bit-rate video and audio stream and the control stream are displayed on a TV wall screen after being processed by the data matrix or decoder; meanwhile, the streaming media server converts the high-bit-rate video and audio stream into a low-bit-rate video and audio stream and sends to the client, and the client displays an image. The invention also provides a video on-wall configuration system for the analog TV wall. The client operation is facilitated and the working efficiency of the client is improved.

The invention provides a method for customizing network broadcasting content. The method comprises the steps of receiving a broadcasting content choice made by a user and determining type and time attributes of the chosen broadcasting content; determining the position of the broadcasting content on a timer shaft according to the type and time attributes of the chosen broadcasting content and forming a timer-shaft broadcasting content view; and presenting the timer-shaft broadcasting content view to the user. The invention also provides a device for customizing the network broadcasting content. The user can add content of live video, live audio, video on demand and audio on demand to the same content broadcasting list, so that mixed editing of content information which comes from different resources is achieved in the same content broadcasting list.
