    Abstract: A coder (e.g., an encoder or decoder) implements coding of two dimensional blocks of image data using two dimensional differential pulse code modulation (2D DPCM). The coder may switch between DPCM and other types of coding, such as transform coding on a block by block basis. The 2D DPCM may obtain a reconstructed pixel within the two dimensional bloc and code a second, different, pixel within the two dimensional block using the reconstructed pixel. The coder may also create a bitstream of entropy encoded residuals that supports hybrid implicit/explicit specification of coding parameters.

    Abstract: A system implements rate control for encoding and decoding operations, for example, operations performed on slices of data such as image data. The system implements a transformation from actual buffer fullness to rate controlled fullness. With the rate controlled fullness model, the encoders and decoders adapt bit allocation responsive to rate controlled fullness, instead of the actual fullness.

    Abstract: An encoder may implement an indexed color history that stores color values for previously encoded pixels. The encoder may obtain a current pixel or current group of pixels for encoding and determine whether to encode the current pixel using the indexed color history. In doing so, the encoder may compare a color value of the current pixel with color values of the previously coded pixels to determine whether the current pixel is sufficiently similar to a previously coded pixel color value, e.g., by satisfying one or more similarity criteria. When the similarity criteria are satisfied, the encoder may encode the current pixel as an index value referencing the entry in the indexed color history storing a color value that satisfies the similarity criteria. When the similarity criteria are not satisfied, the encoder may encode the current pixel using another encoding method or technique.

    Abstract: Disclosed are various embodiments directed to transcoding a bit stream comprising audio and video frames that contains discontinuities. The video and/or audio portion of the bit stream may be divided into segments, where some of the segments are transcoded in parallel using a plurality of transcoder devices. In some embodiments, a discontinuity is detected in the bit stream before encoding, where the discontinuity is associated with a shift in a set of time stamps associated with the bit stream. A magnitude of the discontinuity is determined. The transcoding system aligns at least a portion of the audio frames to the series of video frames according to at least the discontinuity and the magnitude of the discontinuity. In other embodiments, the discontinuity is detected after encoding by analyzing time stamps that have been established during the transcoding process.

    Abstract: Disclosed are various embodiments directed to transcoding a bit stream in parallel. A bit stream may be divided into a plurality of segments, where a plurality of transcoders encode at least a portion of the segments in parallel. If encoding is performed using variable bit rate (BR) encoding, each encoder may encode a segment and vary a BR for the segment. A measured average BR is compared with a target average BR to determine whether to adjust a video quality level (VQL) or any other encoder parameter. A relatively constant subjective quality may be maintained using variable BR encoding while achieving a target average BR. When using constant BR encoding, a VQL or other encoder parameter is used by encoders to achieve relatively constant subjective quality. For example, a relatively continuous quantization parameter between adjacent encoded segments may be achieved.

    Abstract: A Wireless mobile communication (WMC) device may maintain user preference information, which is unique to the WMC device capabilities and the device user. WMC devices located in near proximity of each other may be enabled to form an ad hoc wireless network wherein each WMC device within the network may function as a router for other devices. Utilizing such routing capability within an ad hoc wireless network may allow WMC devices that are out of their wireless coverage area to use other WMC devices within such ad hoc wireless network to route any impending communication through such other WMC devices wherein these devices may have wireless connectivity to their coverage networks. WMC devices that are may have external connectivity may be enable to be selective in routing information and/or data from other WMC devices in the ad hoc network.
