Abstract:
An error correction compensating ones or zeros string suppression system and method for use in a digital transmission system is herein disclosed. In digital transmission systems utilizing error control coding (ECC)/forward error correction (FEC) to reduce the number of bit errors in a bit stream, long strings of ones and zeros are easily suppressed by detecting a prohibited length of ones or zeros, and flipping a bit in the string of ones or zeros. This method and system removes the violation of the ones or zeros bit string requirement by flipping a bit in the string, while the receiving side utilizes the error correction capability of the ECC/FEC to correct the inverted bit.

A system and method for effectively implementing a charging base for a remote control includes a television device that is controlled by the remote control over a wireless RC-TV communications link. The charging base recharges a battery of the remote control when the remote control is docked to the charging base. In addition, the remote control may be docked to the charging base for bi-directionally communicating with the television and other external entities over a wireless base-TV communications link. Furthermore, various compatible peripheral devices may also recharge their batteries and bi-directionally communicate with the television and the external entities over the base-TV communications link while the peripheral devices are docked to the charging base.
Abstract:
A packetized data receiver establishes at the beginning of receiving each respective stream a buffer length for sending packets to higher levels of a protocol stack in the event that a packet is missed. This can be done by requesting retransmission of the first packet and measuring the actual time delay between request and receipt of the retransmitted packet.
Abstract:
A system and method for effectively protecting electronic content information includes a channel setup module that coordinates a channel setup procedure to create a secure communications channel between a content drive and a display module. A source DRM module transmits a special content key from the content drive to the display module over the secure communications channel. A content playback module then initiates a content playback procedure for utilizing the electronic content. The source DRM module responsively encrypts the electronic content with the content key. The channel setup module and the content playback module are unable to access or utilize the content key. A destination DRM module then receives the electronic content over the secure communications channel and utilizes the content key to decrypt the electronic content.

Abstract:
This invention is a data processing apparatus which operates on instruction controlling plural processor actions. Each instruction includes a data unit section and a data transfer section. These instruction sections are independent and may include differing options. In the preferred embodiment, each instruction is 64 bits. The data unit section includes a data operation field that indicates the type of arithmetic logic unit operation and six operand fields. The six operand fields include four source data register fields and two destination register fields. The data unit (110) includes a multiplication unit (220) and an arithmetic logic unit (230). The data unit (110) may include a barrel rotator (235) for one input of the arithmetic logic unit (230). The rotated data may be stored in the first destination register instead of the multiply result. The address unit (120) operations according to the data transfer operation field. This could be a load, a store or a register to register move. Operations may be conditional based upon conditions stored in a status register (210). The status register (210) is set by a prior output of the arithmetic logic unit (230) and the instruction may specify some of the status bits protect from change. The address unit (120) preferably includes a plurality of base address registers (611), a full adder (615) and a left shifter (614). The full adder (615) may add an index as scaled by the left shifter to the base address or subtract the scaled index from the base address. The full adder (615) output may update the base address register (611), either before supply of the address or following supply of the address. The index may be recalled from an index register (612) or an immediate value. In the preferred embodiment of this invention, the data unit (110) including the data registers (200), the multiplication unit (220) and the arithmetic logic unit (230), the address unit (120) and the instruction decode logic (250, 660) are embodied in at least one digital image/graphics processor (71, 72, 73, 74) as a part of a multiprocessor (100) formed in a single integrated circuit used in image processing.
Abstract:
The decode rate of an MPEG decoder of streaming video is set to a relatively slow value at the start of a stream to permit playing, albeit at relatively low speeds, of the video until such time as an appropriate number of packets are in a receive buffer, at which time the decode rate is speeded up to normal.
Abstract:
A data processing apparatus including a multiplier unit forming a product from L bits of each two data buses of N bits each N is greater than L. The multiplier forms a N bit output having a first portion which is the L most significant bits of the of product and a second portion which is M other bits not including the L least significant bits of the product, where N is the sum of M and L. In the preferred embodiment the M other bits are derived from other bits of the two input data busses, such as the M other bits of the first input data bus. An arithmetic logic unit performs parallel operations (addition, subtraction, Boolean functions) controlled by the same instructions. This arithmetic logic unit is divisible into a selected number of sections for performing identical operations on independent sections of its inputs. The multiplier unit may form dual products from separate parts of the input data. A single instruction controlling both the multiplier unit and the arithmetic logic unit permits addition of dual products. The dual products are temporarily stored in a data register permitting the multiply and add operations to be pipelined. The dual products are formed in one data word and added by a rotate/mask and add operation in a three input arithmetic unit.
