Appl. No.:

12/737416

Assignee:

International Classification:

H04N 7/26
H04N 5/44

US Classification:

348725, 37524025, 375E07027, 348E05096

Abstract:

A method and apparatus for fast channel change when changing the channel from a channel being viewed full screen as a main picture to a channel being viewed in a secondary channel program display window (e.g., a picture-in-picture (PIP) window). In one implementation, during the channel change, a secondary video stream for a secondary channel program is up-sampled and displayed full screen while receiving the corresponding regular video stream for the video program, of which program contents are identical to those of the secondary video stream. The program contents of the up-sampled secondary video stream is then be replaced seamlessly with those of the corresponding regular video stream at the time when an instantaneous decode refresh (IDR) frame of the corresponding regular video stream is received. In another implementation, the last GOP packets of the corresponding regular video stream, corresponding to a secondary video stream being viewed in the secondary channel program display window, are buffered without being decoded. Upon a request for the channel change, the buffered GOP packets are decoded and displayed immediately while the decoder starts receiving the following frames in the corresponding regular video stream.

Abstract:

There are provided methods and apparatus for fast channel change when changing the channel from a channel being viewed full screen to a channel being viewed in a secondary display window (e.g., picture-in-picture (PIP) window). In one implementation, the base layer stream of the SVC encoded stream is used as the secondary stream for the secondary display and the corresponding enhancement layer stream is used as the corresponding regular stream. Upon channel change request, the decoded base layer picture of the SVC encoded stream is up-sampled, and the up-sampled base layer picture is displayed full screen while receiving the corresponding SVC enhancement layer stream. Then, the up-sampled base layer picture is replaced by the decoded enhancement layer picture upon confirmation of successful receiving and decoding of an enhancement layer instantaneous decode refresh (IDR) frame. In another implementation, the last GOP of enhancement layer stream corresponding to a base layer stream being viewed in the secondary display window is buffered without decoding, and upon a channel change request to the secondary video display window channel, the buffered packets are decoded and displayed immediately while the decoder continues to receive and decode all frames in the corresponding base and enhancement layer streams.

International Classification:

H04N 7/12

US Classification:

37524012, 375E07243

Abstract:

Methods for concealing Scalable Video Coding (SVC) decoding errors. Lost pictures in the target layer are replaced with up-sampled pictures from a lower layer, such as the base layer. In multiloop decoding applications, lost pictures in the target layer are replaced with corresponding up-sampled pictures from the lower layer. Subsequent target layer pictures in the same Group of Pictures (GOP) are either replaced with corresponding upsampled pictures from the lower layer, or they are decoded with up-sampled pictures from the lower layer used as reference pictures. For single-loop decoding, the bit stream of each layer is buffered, for each GOP, and inspected for errors. If an error is detected in the target layer, the pictures of the highest level layer without an error are decoded and up-sampled and used as the output pictures for the current GOP.

International Classification:

A61N 130

US Classification:

604 20

Abstract:

This invention relates to development of an iontotherapeutic device for regulated transdermal systemic administration of ionizable pharmaceutical compounds. It also provides an iontotherapeutic process for transdermal administration of ionized pharmaceuticals, particularly those which are otherwise transdermally absorbed to a small degree or not all, such as peptide pharmaceuticals, for example, insulins. The invention also relates to unit dose forms, for example, those in which an ionized pharmaceutical is dispersed in a hydrophilic polymer. The unit dose is adapted to be assembled as part of the pharmaceutical reservoir electrode, so that the ionized pharmaceutical will be delivered transdermally and then be absorbed systemically when the iontotherapeutic device is in operation.

International Classification:

A61F 7/00

Abstract:

A wearable device includes a housing to encompass a portion of a body part, biometric sensors coupled to the housing, a controller coupled to the housing and biometric sensors, a communication channel for communicating with external devices and a temperature regulator to controllably adjust a temperature of the housing. The wearable device is configured to provide remote controlled heating and cooling of the body part. The wearable device may include an evaporative heat exchanger and a thermoelectric heat pump. The wearable device may provide means for dissipating heat through vaporization of a substance or using an advective flux and phase transition.
