    Abstract: A receiver which receives a stream of data packets including video data packets over a physical data link and drops data packets when an error on a physical communication layer is detected, wherein the receiver comprises a processor, configured so that it is able to check whether the received data packet is a video packet and whether it is corrupted by an error on the physical communication layer. If this is the case, the video packet is marked as corrupted and forwarded to the network layer. There is further provided a method for processing a stream of data packets including video data packets, the method including checking for each data packet whether it is a video data packet; checking for each video data packet whether it is corrupted by an error on the physical communication layer; marking a video packet as corrupted if it is corrupted due to an error on the physical communication layer; and forwarding the marked corrupted video packet to the network layer.

    Abstract: Determination of the location of an error condition or a failure includes receiving at a network interface a first framed digital signal from customer premises equipment, and determining whether the first framed digital signal indicates a failure. Overhead bits are modified in the first framed digital signal to generate a second framed digital signal, such that the modification is equivalent to insertion of errors into the first framed digital signal at a bit error ratio (BER) of not greater than a predetermined ratio, if the first framed digital signal indicates a failure. The second framed digital signal is then sent from the network interface in place of the first framed digital signal to indicate that the failure reported by the first framed digital signal is located in the customer premises equipment. Otherwise, if no failure is indicated, the first framed digital signal is transmitted without any modifications.

    Abstract: The invention concerns methods and devices for transferring data in a network and in particular the transfer of multimedia data. According to the invention described, a point of interconnection receives a configuration map from a client. When the point of interconnection receives a data packet from a server, it analyzes the received packet in order to detect the errors. If the received packet comprises errors and belongs to a stream identified in the configuration map, the point of interconnection selects error correction mechanisms specified in the configuration map. If these mechanisms are capable of correcting all the errors in the packet the latter is transmitted to the client in its original stream. If errors remain, the point of interconnection creates a new packet comprising the data of the received packet, possibly partially corrected, and information relating to the errors detected, to the correction mechanisms used and to the original identity of the data. The packets created by the point of interconnection are transmitted to the client by a particular stream not participating in the constitution of the original multimedia sequence.

    Abstract: A multimedia distribution system is disclosed. The distribution system includes a transmitter unit that distributes content from a content provider to one or more wireless subscriber units. The transmitter unit includes a decoder configured to determine whether a plurality of incoming packets include one or more erasures, a transmitter configured to transmit the packets to a receiving unit, and an error detection code generator configured to generate an error detection code for each of the packets transmitted to the receiver unit, the error detection code being modified for each of the erased packets so that the receiver unit will be able to identify the erased packets.
