Abstract: A new user interface and display system for a video display device with a touch screen makes it possible to peek at, that is view briefly, a selected video content while watching other content. During a video peek, video from a second video source will be seen to partially displace and temporarily replace a portion of a video presently being viewed. Selection of the other video sources can be controlled, for example, by swiping with one, two, three or four finger tips and by swiping inwardly from any one of the four edges of a video display. Moreover, the video presently being viewed can be interchanged with the video being peeked at.

Abstract: Constant-bitrate rate control is very useful for real-time video transmission. However, it is difficult to realize a good CBR rate control in an MPEG4-AVC video codec. According to the invention, an adapted ?-domain rate control processing for real-time rate control is applied, whereby ? is the percentage of zero amplitude transform coefficients following quantization. A couple of tables are used for mapping between the quantization parameters and ?. A detailed analysis at transform level is carried out in order to get the slope of the relationship between the bitrate and ?. The slope of the linear model is constrained by a look-ahead procedure with respect to the neighbor frames or blocks.

Abstract: A system for line production of a television show can include a newsroom computer system (NRCS 14) which includes a mark-up tool that allows a user to specify temporal metadata corresponding to temporal events contained within a content segment for repurposing content. Through the use of the mark-up tool, a journalist or web producer can use their existing NRCS, or the like, to specify the static, temporal and distribution metadata needed in the production process. Thus, in the event of a change during production, the NRCS can accurately and automatically repurpose the content using previously established temporal metadata.

Abstract: A system and method for initializing a SNMP agent in SNMPv3 mode. In one aspect of the invention, a method is provided that allows an operator to securely enter the initial SNMPv3 privacy and authentication keys into a SNMPv3 device and cause the device to enter in SNMPv3 mode. The SNMP manager and SNMP agent both generate an associated random number and public value. The SNMP manager passes its public value to the SNMP agent in a configuration file, which causes a proprietary MIB element in the SNMPv3 device to be set with the public value of the SNMP manager. The SNMP manager reads the public value of the SNMP agent through a SNMP request using an initial valid user having access to the public value of the SNMP agent. The SNMP agent and SNMP manager each independently compute a shared secret using the Diffie-Hellman key exchange protocol.

Abstract: According to the IEEE1394 bus protocol, priority is given to isochronous data packets. Data transfer is done in transfer cycles under the control of a cycle master. It depends on the allocated bandwidth for isochronous data how much transport capacity is available in a transfer cycle. To managed the mixed data transfer in one cycle it is specified that the bus nodes not having isochronous data to transfer need to wait with their transmission requests until the end of the isochronous data transfers in the cycle indicated with a sub-action gap. The invention aims to improve the efficiency of data transport for the case that none of the bus nodes need to transfer isochronous data. The data link layer devices according to the invention includes means for checking whether isochronous data is to be transferred and if not they switch over to a no cycle master state, in which the local cycle synchronization events are ignored.

Abstract: A method of detecting the reliability of a field of movement vectors of one image in a sequence of video images. The method includes a stage of calculating a stability parameter, Det_Stab(t), for the field. The parameter is based on a comparison (4), over two successive images, of the number of occurrences of the majority vectors of the movement-vectors fields of each of these images. A field is defined as stable if the variation in the number of occurrences lies within a predefined bracket. Reliability (7) is decided on the basis of this stability parameter.
