    摘要： Interpolating a low or medium resolution image to a higher resolution image using a pixel replication and averaging technique. An overlay image having pixels of a first display resolution and a plurality of alpha blending values each indicating the degree of blending with a background image is interpolated to the resolution of the background image. In addition to interpolating pixel values, alpha blending values are themselves interpolated and multiplied by corresponding overlay pixel values prior to being blended with the background image.

    摘要： A graphics blending feature for a terminal such as a home communication terminal (HCT) allows an overlay image to be selectively blended with a background image through the use of a chroma key function and one or more alpha control bits. The chroma key function is used to determine whether the overlay will be completely transparent or not, and the one or more alpha control bits are used to look up a larger alpha value used to blend the overlay and background images. By using a small number of alpha control bits to retrieve a larger alpha value for blending, memory requirements per pixel are reduced. The chroma key function may be implemented by comparing each overlay pixel value to a chroma value and, responsive to a match, making the overlay pixel transparent (i.e., no blending occurs). A dithering function is included in various embodiments to smooth out the resulting image.

    摘要： A system and method for personal video recording (PVR) is provided for recording digitally encoded streams, and for playing back and decoding the recorded streams. The PVR system may receive the digitally encoded streams from a digital cable box or a network server. The system enables trick modes including fast forward and reverse mode displays at various speeds. The system an method for PVR may also be applied to digitally encoded streams without I-pictures, such as, for example, progressive refresh streams or HITS streams. Reverse decode and display may be implemented by starting at a suitable entry point, decoding quickly up to the point of the desired picture, and displaying the result, and repeating the process. Index tables of entry points may be used for proper operation in some modes where the entry points are entry pictures (E-pictures) which start a pattern of progressively refreshing I-slices.

    摘要： Point to multi-point wireless video delivery. Among a group of receiver wireless communication devices (RXs), one is designated (e.g., as acknowledgment (ACK) leader). Media delivery operational parameters are selected based on the designated RX or based on all or a subset of the RXs. For simultaneous media delivery to multiple RXs, characteristics associated with the designated RX [or all, or a subset or RXs] govern the manner by which communications are made. Different respective RXs may be designated to serve in this role at different times. Wireless delivery of media (e.g., video signaling, audio signaling, etc.) to a group of RXs is effectuated in accordance with modified multicast signaling with a designated leader (e.g., ACK leader). Among a group of devices, a least successful receiving device that still receives media at an acceptable level may be chosen as the designated leader (e.g., ACK leader).
