Abstract:
The present invention relates to methods for synchronizing the transmission and the reception of a media stream over a network, such as the Internet, comprising of a receiver clock having an adjustable reset value, where the adjustable reset value may be a function of the reference time for a receiver clock and the reference time for a sender clock.
Abstract:
Techniques are disclosed for multiplexing a dynamic bit-rate video stream with an audio stream received by a client device in a manner that allows the resulting multiplexed stream to be played back without disruption, despite dynamic changes in the bit rate of the video stream that may occur. A content server may stream both a video stream and an audio stream to a client device for playback. The client device may multiplex the video and audio streams prior to them being presented to a playback engine for decoding and playback to a user.
Abstract:
A conductive element and a lamp using the same are described. The conductive element includes a sleeve portion and a conductive portion, and the conductive element is applied to a lamp reflector. The lamp reflector has a main body and a neck portion connected to each other. The sleeve portion of the conductive element is installed in the neck portion, and then a discharge lamp tube through from the main body to the sleeve portion in the neck portion, and the conductive portion forms an included angle with the discharge lamp tube. Therefore, a length achieved after the discharge lamp tube and the lamp reflector are assembled together is shortened.

Abstract:
A disposable plastic injection molded probe cap used in conjunction with a measuring probe of an infrared instant thermometer, essentially comprised of a closed end at the top and an open bell, wherein, the thinner closed end provided with a window portion is connected to the bell by side wall, a fastening portion of the side wall having its diameter slightly smaller than the outer diameter of the front end of said probe for the ear probe cap to interference fit to the front end of the measuring probe is formed at where near to the window portion, in addition, a flange can be formed on the side wall.
Abstract:
Techniques are described herein for using cryptographic elements of the Advanced Access Content System (AACS) in a client-server environment to cryptographically authenticate client applications that are executing on non-revoked AACS-compliant playback devices. The techniques described herein may be used to protect a server application from providing information to client applications executing in non-AACS-compliant or revoked environments. In one embodiment, the techniques are used to authenticate a Blu-ray Disc Java Application executing on a non-revoked AACS-compliant Blu-ray Disc Player.
Abstract:
A content protection system for securely delivering audio/video data from a content server to a content client through an unsecured channel is disclosed. For each session, the content protection system comprises two phases. The first phase is client-server mutual authentication and session key establishment. In this phase, the content server and the content client verify each other's legitimacy, and at the same time exchange information so that both server and client can calculate or derive the same session key. In the second phase, audio/video data is encrypted with the session key in the content server, and then decrypted with the session key in the content client. If a version of server or client is found to be compromised, its ID will be put into a blacklist.
Abstract:
Embodiments for changing bit rates in streaming media are provided. As portions of a streaming media file are downloaded for playback, the size of the portion is compared with an expected size determined prior to initiating playback of streaming AV data. The portion of the media file may be padded such that the size of the portion matches the size specified prior to initiating playback of streaming AV data.
