Abstract: Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.

Abstract: A receiving system and a method of processing broadcast signals in the receiving system are disclosed. The receiving system includes a tuner, a known sequence detector, a carrier recovery unit, a baseband processor, and a channel equalizer. The tuner receives a broadcast signal of a passband including a data group. Herein, the data group comprises mobile service data, a plurality of known data sequences, and signaling data. The known sequence detector estimates an initial frequency offset and detects a position of each known data sequence based on the known data sequence having the first data pattern. The carrier recovery unit acquires an initial frequency synchronization using the initial frequency offset estimated by the known sequence detector and estimates a residual frequency offset based upon the known data sequences having the second data pattern so as to perform carrier recovery. The baseband processor performs complex multiplication between the received broadcast signal and an output of the carrier recovery unit, thereby converting the passband broadcast signal to a baseband broadcast signal.

Abstract: Error correction coding for streaming communication is provided. A streaming problem is modeled as a non-multicast network problem with a nested receiver structure. Each packet in the streaming problem corresponds to a link, and each deadline in the streaming problem corresponds to a receiver in the non-multicast network problem. For the non-multicast network problem, content to be transmitted in multiple packets to multiple receivers is obtained. Each of the receivers is required to decode specific independent messages from the content, at given time steps, and has access to a subset of the content received by another receiver. The content is allocated into multiple packets to be transmitted on multiple links. No coding occurs across information demanded by different receivers. A capacity region defines a set of information rate vectors that can be communicated to the receivers successfully. A rate vector is successfully communicated if it complies with various inequalities.

Abstract: In one embodiment, protocol violations of a particular protocol are induced at one or more predetermined intervals within a particular stream of information encoded according to the particular protocol in order to produce a marked particular stream of information for use in subsequent identification of the marked particular stream of information. The marked stream is multiplexed or otherwise communicated to a second device. The second device detects, and typically corrects, the induced protocol violations. And based on which stream of information included the induced protocol violations and the multiplexing/distribution pattern of the other streams of information, the second device can identify which stream is which and process or forward accordingly.

Abstract: A first device receives first data that includes a plurality of input vectors, which includes a primary input vector and a set of secondary input vectors and detects uncorrectable errors in the first data based on a quality metric indication. Based on detecting the uncorrectable errors in the first data, the first device substitutes a predetermined codeword for the primary input vector encoded using a non-perfect code, and substitutes a predetermined input vector for the primary input vector. The first device modulates a set of encoded secondary input vectors using the predetermined input vector to generate a modulated set of encoded secondary input vectors and transmits as second data the predetermined codeword and the modulated set of encoded secondary input vectors to a target device, wherein the substituting step creates a first number of errors that is detected by the target device as uncorrectable errors in the transmitted second data.
