A system is provided for delivering Internet and digital content to a variety of thin client devices. A web portal for accessing and selecting content is used in conjunction with graphical user interfaces on a personal computer for setting up and controlling the content channels. The user interfaces, scheduling, and communication management are controlled by a system control software application running on a local server with an Internet connection. A high speed local area network provides for streaming content from the Internet or local server to thin client devices. A digital audio playback device is connected to the local server via the local area network connection and decodes streamed audio files, and converts them into analog audio signals for input into a conventional stereo. Digital content is streamed automatically from the local server to another Internet playback device, based on end user content preferences and schedule selections.

A scheme for transmission of control channel information in a compact form intended to support SPS (Semi-Persistent Scheduling) in a wireless communication system. As applied to LTE, the scheme is to indicate a pre-configured UE-specific resource allocation in a Downlink Control Information (DCI) format containing information for multiple UEs in the same PDCCH. In order to avoid increasing the number of blind decodes, the DCI format size may be the same as an existing DCI format. Preferably the size of the new format is the same as that of DCI formats 0/1A/3/3A. The number of required bits per UE is minimised by signalling only one of a limited set of DCI messages per UE. The scheme provides a means for re-configuring SPS resources for multiple UEs using a single PDCCH transmission, whilst enabling better support for variable packet sizes and variable intervals between packets than currently defined SPS.

The invention discloses a polarization code and multi-bit even parity check code cascaded error correction coding method. The method comprises the steps: a transmitting end encoder utilizes a multi-bit even parity check code as an outer code, and utilizes a polarization code as an inner code; a receiving end decoder decodes by utilizing a modified successive cancellation list (SCL) decoding algorithm.

On the aspect of engineering realization, according to the polarization code and multi-bit even parity check code cascaded error correction coding method, the outer code utilizes the multi-bit even parity check code, which is simple to code; the modified SCL decoding algorithm is utilized to decode, bit decision and even parity check are combined to be carried out in a decoding process, and compared with the original SCL decoding algorithm, the method provided by the invention does not increase the decoding complexity, and facilitates the engineering realization.

Tools and techniques for applying scan patterns during encoding and decoding of progressive video are described. For example, a video decoder entropy decodes transform coefficients in a one-dimensional array and scans the transform coefficients into a block according to a scan pattern. The block is 8×4, and the scan pattern biases the vertical direction for at least the lowest frequency AC coefficients in the horizontal and vertical directions. Or, the block is 4×8, and the scan pattern biases the horizontal direction for at least the lowest frequency AC coefficients in the horizontal and vertical directions. A corresponding video encoder applies the scan patterns to scan transform coefficients from blocks to one-dimensional arrays.

An apparatus and a method for inserting and displaying one or more signals during processing and display delays encountered in digital STB-receivers, including those delays encountered during channel changes. Moreover, a means for increasing the channel change delay period, while maintaining subscriber satisfaction, and thereby freeing up bandwidth for other services, is provided.

Providing advertisements or entertainment during the delay period allows for increase in the delay period thus allowing for higher compression and increased availability of bandwidth.

A data code label including a QR code and an ID tag including a memory having an identification code area and a decode data writing area. A data code in the QR code showing an error in decoding is corrected and stored in the memory in the ID tag while the degree of defection of the QR code is low.

If the decode data cannot be read, the error correction is effected. If the error rate is higher than a reference, the decode data is obtained from the memory. If this decreases the error rate under the reference, the error correction is effected.
