Power management for a multi-processor chip includes a centralized global power manager that monitors global power for the whole chip, and local power managers. Local power managers manage power for local blocks such as processor cores, caches, and memory controllers. When a local block executes an instruction or accesses memory, an event is generated and looked up in a local power estimate table. A local power estimate for that event is sent to the global power manager, which sums all local power estimates received from all local blocks. An exponential moving average (EMA) is generated and compared to a global power threshold. When global power is over the threshold, local targets are sent to power managers that generate and monitor local power averages that must remain under the local target. The local block is throttled by the local power manager to reduce power when the local target is exceeded.

A die with embedded memory is packaged together in a same dual-chip package with an EEPROM die. Defects in the embedded memory can be repaired using redundant rows or columns. A built-in self-test (BIST) controller locates defects and a repair image is generated. The repair image is stored in non-volatile memory in the EEPROM die. At power-up, the repair image is copied from the EEPROM die to a volatile repair RAM in the embedded memory die. The redundant rows or columns are mapped to replace defective rows/columns using the repair image in the volatile repair RAM. Although the embedded-memory die has only volatile memory and no fuses, its embedded memory can be repaired using the repair map from the non-volatile EEPROM die. Since the EEPROM die is in the same dual-chip package as the embedded memory die, the repair map is always available.

A method and system that computes viewing statistics for a digital video content stream received at a set-top box. The digital video content stream includes a first segment of video content, a second segment of video content, a third segment of video content, a first timing mark that indicates a transition from the first segment to the second segment, and a second timing mark that indicates a transition from the second segment to the third segment. The method initiates a transmission of the digital video content stream at the set-top box, monitors the transmission of the digital video content stream relative to the first timing mark and the second timing mark, and computes view data for the second segment based on the monitoring of the transmission. The method stores the view data at the set-top box.

A method and computing device that provides viewer impression data for a recorded digital video stream. The method receives a digital video stream as a series of segments, and stores it as a recorded digital video stream having a transition between two consecutive segments at a transition position. The method stores a notification tag that is associated with the transition, and that includes a tag position in the recorded digital video stream, a notification mode, and tag data. During playback of the recorded digital video stream, the method generates a play mode status event, and generates a transition notification when the playback encounters the notification tag and, based on the notification mode, the transition associated with the notification tag. The method collects viewer impression data for one of the two consecutive segments from the play mode status event and the transition notification.

A method of operating a digital video service set top box system is provided. The set top box system accommodates playback of locally stored recorded secondary digital video content. The method begins by initiating playback of a primary digital video program. Insertion points associated with the primary digital video program are detected; these insertion points indicate frame-accurate transition points in the primary digital video program. During playback of the primary digital video program, the recorded secondary digital video program is inserted at any appropriate insertion point in a frame-accurate manner. The termination of the secondary digital video program is likewise marked and triggers a return to the primary digital video program, at the original insertion point or any other desired insertion point which may exist in the primary digital video program.

In a method for transitioning between multiple services in an MPEG stream, the MPEG stream including a pre-transition service and a post-transition service is received. In addition, a service transition point that identifies a location in the MPEG stream where the MPEG stream transitions from the pre-transition service having a first set of packet identifiers (PIDs) to the post-transition service having a second set of PIDs is detected for the MPEG stream and the second set of PIDs is mapped to have the same values as the first set of PIDs.

This is a method and apparatus for interleaving data in a VRAM. A video card is provided which has less VRAMs than the equivalent prior art video cards which have the same speed and same size data paths. Herein is utilized non symmetrical column interleaving whereby each pixel on the display having coordinates X, and Y is mapped into the VRAMS rows and columns R and C according to the formula:R=[TTI of 2(Y/3)]+P1C=LNB{[(TTI of Y mod 3) 341]+[TTI of X/3]}where:TTI means truncation to an integerLNB means lower nine order bits of P1 is "1" if [((X>511) and (Y mod 3=1)) or (Y mod 3=2)]Utilizing the asymmetrical column interleaving of the method and apparatus the rows of each VRAM are completely filled and one can produce a video card for 1024 by 768 display with 8 bits per pixel utilizing three 2 megabit VRAMS.
