摘要： The described embodiments relate to methods and systems for detecting the blockiness of a video signal comprised of a number of pixels. The method includes the steps of determining if the pixel forms a part of at least one visible horizontal transition along a macroblock border, at least one visible vertical transition along a macroblock border, at least one flat area or at least one flat macroblock; calculating a horizontal border transitions count, a vertical border transitions count, a flat area count and a macroblock flat area count; and generating at least one blockiness indicator for the region of interest selected from the group consisting of a block border indicator, a flat area indicator and a flat block indicator, wherein the at least one blockiness indicator is based on at least one of the horizontal border transitions count, the vertical border transitions count, the flat area count and the macroblock flat area count.

摘要： Apparatus, systems and methods for routing an input serial digital interface (SDI) signal from an input SDI port to an output SDI port are described. In at least one embodiment, at least one input card, at least one output card, a midplane coupled to the at least one input card and at least one output card and a controller coupled to the midplane are disclosed. At least one input card being configured to receive the input SDI signal at the input SDI port, process the input SDI signal to generate one or more packetized media streams, each including a plurality of packets, with each packet having a packet header including a source address corresponding to that packetized media stream, and transmit each packetized media stream from an IP output port to the midplane. The midplane being configured to identify the source address corresponding to each packet of a packetized media stream, process the corresponding packets to insert a destination address based on controller instructions, and generate and route a corresponding processed packetized media stream based on the destination address. The output card being configured to receive one or more processed packetized media streams at an input IP port, process the received streams to generate a corresponding output SDI signal, and provide the output SDI signal at the output SDI port.

摘要： Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

摘要： A system and method are provided for determining delay of a plurality of media streams. The system and method involve generating, at a source processor, a series of source time packets; transmitting, at the source processor, through a network, the series of source time packets as a source packet stream; generating, at a destination processor, a series of destination time packets; receiving, at the destination processor, through the network, the source packet stream; determining, at the destination processor, a transmission time for the source packet stream based on the source time data and the destination time data; and determining, at the destination processor, a relative synchronization error based on the source signature data and the destination signature data. Each source time packet includes source time data and source signature data. Each destination time packet includes destination time data and destination signature data.
