Abstract: Server-side trick mode restrictions in a stream may be provided. The stream may comprise, for example, a Video on Demand (VOD) Adaptive Bitrate (ABR) stream. First, a playlist request corresponding to a stream may be received from a user device. Next, a current stream position in the stream may be determined. In response to receiving the playlist request and when the current stream position corresponds to a non-skip segment, a playlist may be created having a last chunk comprising a next chunk of the stream from the current stream position. The playlist may then be provided to the user device.

Abstract: In one embodiment, a first apparatus includes a processor and an interface, wherein the interface is operative to receive a request from a second apparatus to commence a keyed-hash message authentication code (HMAC) computation, the processor is operative to perform a first computation computing a first part of the HMAC computation using a secret key K as input yielding a first value, the interface is operative to send the first value to the second apparatus, the interface is operative to receive a second value from the second apparatus, the second value resulting from the second apparatus processing the first value with at least part of a message M, the processor is operative to perform a second computation based on the second value and the secret key K yielding an HMAC value, and the interface is operative to send the HMAC value to the second apparatus.

Abstract: A system, apparatus and a method for providing a flexible framework for a video processing infrastructure to enable rapid integration of video analytics algorithms in video security systems. Such a flexible framework preferably features a plurality of ready-to-use libraries, as well as at least one “skeletal” module into which customized programming may be inserted. The skeletal module preferably comprises a generic customizable interface to a hardware device or system, described collectively herein as a video processor.

Abstract: A method, device, and system for facilitating the use of and data entry into a computer having a data entry device such as a keyboard and a display device such as a monitor. A camera is disposed above the keyboard and captures a moving image of the keyboard. The image of the keyboard is shown on th display device, preferably in a small portion of the display device. In this way, a person can look at the display device and see both the subject matter he is typing or entering and the keyboard at the same time. An image of the user's hands is made transparent and overlaid onto the image of the keyboard. The image of the keyboard can be manipulated, e.g., made smaller or larger, corrected for parallax and movement, the characters on the keys can be changed, and the like.
