摘要： Encoding a video signal according to a scalable video coding (SVC) technique employs two different encoding paths for the base layer and the enhancement layers respectively, whereby the two encoding paths share common hardware encoding modules. For example, a control module can route received video information associated with the base layer directly to the hardware encoder modules for encoding, while routing video information associated with the enhancement layers to an upscaler. The upscaled video information is then provided to the hardware encoder module for processing in similar fashion to the base layer information. The hardware encoder provides encoded video information to another control module, which determines whether to route the information to a hardware or software entropy encoder, based on whether the encoded video information is associated with the base layer or an enhancement layer, respectively.

摘要： A method and apparatus for dynamic data rate adjustment of a wireless transport channel include processing that begins with one of a plurality of client modules within a wireless multimedia system monitors channel characteristics of a wireless transport channel. The monitoring is done at or below a received packet rate to determine variations in the channel characteristics on a packet-by-packet basis or on a group-of-packets by group-of packets basis. The processing continues when the client module determines whether the variations in the channel characteristics affect the data rate of data contained in the packets received via the wireless transport channel. When the variations in the channel characteristics affect the data rate, the client module provides data rate adjustment feedback to a multimedia server of the wireless multimedia system via the wireless transport channel. The processing continues when the multimedia server adjusts the data rate of the data contained in the packets being transported via the wireless transport channel in accordance with the data rate adjustment feedback.

摘要： The size of received multimedia data (108; 208) is changed by a processing device (102) based on at least a first characteristic of the content. The size can be adapted by changing the bit rate of the received multimedia data, changing a resolution of the received multimedia data, or changing an audio volume of the received multimedia data. The transrating of the multimedia can use rule sets based on content characteristics. An appropriate rule set (326) can be selected using program information (329), such as from an EPG (318). After transrating, the multimedia data can be transmitted via a network to a destination multimedia device (210) or stored locally (106) for subsequent use. An index table can be used to reference a portion of the data with the first characteristic or an identifier can be inserted (316) into the received multimedia data at that point. The data size can also be based on remaining storage capacity.
