Abstract: Disclosed herein are a method and apparatus for processing MMTP packets. When an MMTP packet is transmitted, the packet processing apparatus calculates a reference value from partial field values of a reference MMTP packet header, and inserts the calculated reference value into the compressed header. By the reference value, MMTP packets may be correctly distinguished and may be correctly referred to when there are two reference MMTP packets in which the lower 5 bits of packet sequence numbers are identical to each other, or even when the number of reference MMTP packets is a multiple of 256.

Abstract: Disclosed herein are an in-network caching apparatus and method. The in-network caching method using the in-network caching apparatus includes receiving content from a second node in response to a request from a first node; checking a Conditional Leave Copy Everywhere (CLCE) replication condition depending on a number of requests for the content; checking a priority condition based on a result value of a priority function for the content; checking a partition depending on the number of requests for the content; performing a cache replacement operation for the content depending on a result of checking the partition for the content; and transmitting the content to the first node.

Abstract: A digital signage system and a method of providing information using the digital signage system are disclosed. The digital signage terminal includes an emergency detection unit, an emergency detection message generation unit, a communication unit, and an emergency alert message processing unit. The emergency detection unit collects the surrounding emergency-related information of the digital signage terminal. The emergency detection message generation unit generates an emergency detection message including the collected emergency-related information. The communication unit transmits the generated emergency detection message to a digital signage server, and receives an emergency alert message including an emergency alert corresponding to an emergency situation from the digital signage server. The emergency alert message processing unit parses the emergency alert message, and provides the emergency alert included in the emergency alert message to a user.

Abstract: The present invention relates to an apparatus for processing an MPEG Media Transport (MMT) signaling message. As the apparatus for processing an MMT signaling message according to an embodiment, an MMT receiving device includes a context information measurement unit for measuring network context information to be reported to an MMT sending device. A Reception Quality Feedback (RQF) message generation unit sets a valid field indication value and a measured value for the network context information in an RQF message. An RQF message sending unit transmits the RQF message to the MMT sending device.
