Mar 21, 2012

Appl. No.:

13/425914

Inventors:

Jin Zhang - Newark CA, US
Xiaolin Che - Shanghai, CN

Assignee:

Marvell International Ltd. - Hamilton

International Classification:

H04N 5/445

US Classification:

348726, 4552341, 4552342

Abstract:

A demodulator includes an analog to digital converter configured to receive a television signal from a tuner and output a corresponding digitized television signal, where the television signal comprises a digital television signal or an analog television signal. A first gain module is configured to generate, based on the digitized television signal, a first feedback for adjusting the television signal provided to the analog to digital converter by the tuner, where the first feedback is applied to the television signal regardless of whether the television signal is a digital television signal or an analog television signal. A second gain module is configured to generate second feedback for further adjusting the television signal provided to the analog to digital converter by the tuner, where the second feedback is provided to further adjust the television signal only when the television signal is an analog television signal.

Abstract:

A virtual reality (VR) system supports improved interactive control processes/services. These interactive control processes/services include detecting movement of a controller associated with a virtual reality (VR) environment, determining an angle of rotation based on the movement, determining a magnitude of force associated with the movement, determining a path in the VR environment that corresponds to the angle of rotation and the magnitude of force, and projecting the path in the VR environment.

International Classification:

H04L 29/08
G06F 17/30
G06F 21/64

Abstract:

A multi-tenant storage system can store clear text data and associated clear text checksum received from a storage tenant using their associated cryptographic key (“cryptokey”). When the clear text data is compressible, cryptographic data (“cryptodata”) is generated from a concatenation of the clear text checksum and compressed clear text data using the cryptokey. A cryptographic checksum (“cryptochecksum”) is generated from the cryptodata. When the clear text data is uncompressible, cryptographic data (“cryptodata”) is generated by encrypting the clear text data using the cryptokey with an extra verification step to make sure the clear text checksum can be rebuilt during the read request. A cryptographic checksum (“cryptochecksum”) is generated from the cryptodata. The cryptodata and associated cryptochecksum are stored in the multi-tenant storage system, so that repairs to damaged cryptodata can be made using the associated cryptochecksum.

Abstract:

A tenant's clear text data in a multi-tenant storage system can be encrypted using the tenant's cryptographic key to produce encrypted yet compressible data (“cryptographic data”). The cryptographic data can be encrypted using a system cryptographic key that is managed by the multi-tenant storage system and then stored. Use of the system cryptographic key allows for subsequent maintenance activities such as deduplication and compression to be performed on data stored in the multi-tenant storage system without having to access any of the tenants' cryptographic keys.

International Classification:

G06F 3/06

Abstract:

In a storage cluster having nodes, blocks of a logical storage space of a storage object are allocated flexibly by a parent node to component nodes that are backed by physical storage. The method includes maintaining a first allocation map for the parent node, and second and third allocation maps for the first and second component nodes, respectively, executing a first write operation on the first component node and updating the second allocation map to indicate that the first block is a written block, selecting the second component node for executing a second write operation, and executing the second write operation on the second component node. Upon execution of the second write operation, the third allocation map is updated to indicate that the second block is a written block and the first allocation map is updated to indicate that the second block is allocated to the second component node.
