Filed:

Feb 26, 1999

Appl. No.:

09/258507

Inventors:

David Randall Ronca - San Jose CA
Stephen Francis Ruhl - Campbell CA

Assignee:

Mitel, Inc. - Herndon VA

International Classification:

G10L 1304

US Classification:

704260, 704258

Abstract:

A text-to-speech converter includes a text-to-speech engine receiving source text and converting the source text into speech data. A read mechanism reads speech data from the text-to-speech engine and writes the speech data to a buffer. A throttle mechanism reads speech data from the buffer and conveys the speech data to a playback operation. The throttle mechanism triggers the read mechanism to read data from the text-to-speech engine and writes the speech data to the buffer so that unread speech data in the buffer remains ahead of speech data read by the throttle mechanism by at least a predetermined amount.

Appl. No.:

09/259986

Inventors:

David R. Ronca - San Jose CA

Assignee:

Mitel, Inc. - Herndon VA

International Classification:

G06F 1700

US Classification:

709104, 370231, 370257

Abstract:

A resource allocation manager to allocate resources to handle applications in a messaging system includes a database storing a set of resource allocation rules to govern the allocation of resources to applications. A resource allocation engine is responsive to events that potentially effect the manner in which resources are allocated. The resource allocation agent accesses the database and interprets the resource allocation rules in response to events to determine if the events warrant a reallocation of resources to handle applications. Allocation agents are responsive to the resource allocation engine and reallocate resources to handle applications when detected events warrant a reallocation of resources. A method of allocating resources in a messaging system is also provided.

David Randall Ronca - San Jose CA

Assignee:

Mitel, Inc. - Herndon VA

International Classification:

H04M 164

US Classification:

379 8825, 379 8818, 379 85, 379 87

Abstract:

A messaging system to store and retrieve messages for playback in response to input user commands includes memory to store user messages. The messaging system also maintains preference records associated with users of the messaging system. Each preference record is associated with a communication device used by a user to access the messaging system and includes user preference data for message playback. A messaging application is responsive to incoming calls from users to playback messages for that user stored in the memory. The messaging application accesses preference records associated with a user calling the messaging system and plays back the messages in accordance with a selected one of the preference records. In one embodiment, the selected one of the preference records is selected based on caller line identification (CLI) data accompanying the call made to the messaging system.

Assignee:

Netflix, Inc. - Los Gatos CA

International Classification:

H04N 7/12
H04L 12/66

US Classification:

37524002, 370352

Abstract:

One embodiment of the invention sets forth an encoding server including components configured to encode a video stream associated with a content title for adaptive streaming. The video stream is first processed by a VC1 encoder to generate an encoded video stream comprising a multiple GOPs, each GOP including a key frame and having a different playback offset. The encoded video stream is then packaged such that the GOPs are stored in data packets of the packaged encoded stream. An SHI generator generates an SHI associated with the packaged encoded stream that includes a switch point associated with each GOP. Each switch point includes the playback offset associated with the corresponding GOP and the data packet storing the key frame of the corresponding GOP. The SHI associated with multiple packaged encoded video streams associated with the same content title and encoded to different playback bit rates have corresponding switch points.

International Classification:

H04L 29/06

US Classification:

380201, 713193, 713182, 713189

Abstract:

One embodiment of the present invention sets forth a technique for decrypting digital content in a secure environment. The technique includes the steps of receiving a digital rights management (DRM) license associated with a first frame of encrypted data from a DRM server, where the DRM license includes a decryption key for decrypting the first frame of encrypted data, transmitting the DRM license to a secure content playback pipeline for storage, and transmitting the first frame of encrypted data to the secure content playback pipeline for decryption, where, in response to receiving the first frame of encrypted data, a trusted processing entity within the secure content playback pipeline decrypts the first frame of encrypted data based on the decryption key included in the DRM license to generate a first set of decrypted data and store the first set of decrypted data in a secure memory space.

US Classification:

37524001, 709231, 375E07003

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.

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.
