Abstract: A transcoding device receives an input stream representing media information designated for display at a sink device. The transcoding device generates multiple display streams based on the input stream, wherein each of the display streams has a different transmission characteristic, such as a different bit rate or resolution. The transcoding device selects one of the generated display streams based on a network characteristic, such as a bandwidth or latency, and communicates the selected stream to the network for transmission to the sink device. In response to a change in the network characteristic, a different one of the generated display streams is selected and communicated to the network for transmission to the sink device.

Abstract: A media source device includes media files in either original source format or in alternative digital formats, based on a content descriptor indicated by a client device from a plurality of content descriptors generated to represent possible transcodings of the source format. In the alternative, a media source device can receive a client device report and subsequent request for a media file. The media source device can send the media file to the client device in a particular digital format based on whether the content descriptor corresponding to the media file is compatible or incompatible with the client device. The bit rate used to send the media file to the client device can be adjusted based on the available transmit bit rate.

Abstract: A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and the state machine executes a process of selecting at least one stream as a target for lowering total bandwidth usage. Once the target stream associated with a client receiver unit is chosen, the amount of data transmitted by the target stream is reduced, which could result in a lower data transmission rate. In one embodiment, the amount of data is reduced by a gradual degradation of the precision of the data, resulting in a greater potential for data compression, and/or by gradually reducing the resolution of the data of the target stream.
