  • Patent number: 9942797
    Abstract: A system and method of permitting coexistence of WiFi and Bluetooth® data transfer on a single chip in UE including a transceiver includes using CTS data packets to protect Bluetooth® signals for SCO communication links; using only WiFi circuitry in the chip to determine when Bluetooth® data transfer is required by the UE; establishing a specified period of the Bluetooth® data transfer; and starting WiFi medium contention only upon an end of the specified period of the Bluetooth® data transfer on the single chip. The power save mode of the WiFi circuitry may be used with Bluetooth® ACL data packets in WiFi periodic data transfer gaps. The WiFi data transfer has no timing constraints, whereas the Bluetooth® data transfer has timing constraints and can only occur during the specified period. The WiFi data transfer does not occur when the Bluetooth® data transfer is occurring.

  • Patent number: 9629150
    Abstract: Unbiased media contention in the presence of conflicting wireless operation of data transmission includes beginning media contention only during Bluetooth® operation; treating the Bluetooth® operation as a rejection of media transmission; holding a backoff timer associated with a backoff period steady for a specified duration; upon immediate completion of the Bluetooth® operation, WiFi contends with a small backoff value when media access is busy; using a small random number for the backoff period during a non-Bluetooth® data transfer period; and keeping an overall backoff timer unbiased for a duration of the data transmission. The specified duration may include an end of the Bluetooth® operation or a maximum backoff time that is reached. The random number for the backoff period includes uniform distribution in a contention window. A mean backoff timer value equals a uniform mean value minus a ratio of a Bluetooth® operation period to a total backoff period.

    Abstract: Memory management for WiFi Media Access Control (MAC) frames includes dividing a memory into equally-sized smaller chunks; writing a MAC frame that is larger in size than one-chunk size into several chunks; appending special information to each chunk to specify whether the chunk is a starting chunk or an intermediate chunk of the MAC frame or whether the chuck is currently unoccupied at all; linking the chunks carrying the MAC frame; and specifying a task waiting to be performed for the MAC frame. The several chunks may be noncontiguous or contiguous. The memory management technique may further comprise searching the memory for chunks comprising frames waiting for a certain task. The memory management technique may further comprise marking the chunks as empty after the certain task is completed.

    Abstract: Reducing a frame size in a memory for a receiver includes compressing a first analog television picture frame, storing the compressed frame in the memory, decompressing the compressed frame from the memory, obtaining a second analog television picture frame. The first frame includes a first set of pixels that further include at least one of Red/Green/Blue (RGB) samples and, the second frame includes a second set of pixels. Each of the first set of pixels of first frame being decompressed are compared with the corresponding second set of pixels of second frame to obtain an alpha (?) factor. A Signal to Noise Ratio (SNR) and a motion per pixel of the first set of pixels and the second set of pixels are compared. Each of a pixel is displayed based on the ? factor.

  • Patent number: 8331709
    Abstract: Performing real-time compression on an image for target buffer fullness includes dividing the image into N macro-blocks, performing a discrete cosine transformation (DCT) on each of the N macro-blocks, defining a Quantization Parameter Scalar (Q) for each of the N macro-blocks of the image on the DCT being performed, initializing the Quantization Parameter Scalar (Q) for the first Macro-block to a value that correlates to a buffer fullness of a previously compressed image, and monitoring the buffer fullness by comparing the buffer fullness with the target buffer fullness. The N macro-blocks include 16×16 macro-blocks. The Q value is increased to a first new value when the buffer fullness is greater than the target buffer fullness. The Q value is decreased to a second new value when the buffer fullness is less than the target buffer fullness.

  • Patent number: 8306343
    Abstract: A technique for optimizing a prediction method of samples in blocks of an image is provided. The image includes a first block, a second block, a third block, and a fourth block, each of the blocks include 8×8 blocks and form one Macro block. The method includes performing a prediction of the second block, the third block and the fourth block by performing at least one of prediction methods. A prediction error per block (Pe) is computed for each prediction method that is performed to predict the second block, the third block, and the fourth block. The prediction error per block (Pe) equals an original block value minus a predicted block value. An optimal prediction method is chosen from each of the prediction methods performed that results in minimum ?|Pe| pixels per block (summation on pixels per block). The optimal prediction method and the Pe for each block are stored.
